In fact, a 2016 archeological dig in Israel found evidence that nuts formed a major part of our ancestors’ diet 780,000 years ago.

Dig researchers discovered seven varieties of nuts, along with stone tools to crack them open. These stone tools, called “nutting stones,” are similar to those found in the United States and Europe, and archeologists date them back 4,000 to 8,000 years.

Today, many of us enjoy walnuts, almonds, pecans, Brazil nuts, pistachios, cashews, macadamia nuts, and hazelnuts, plus honorary peanuts (even though peanuts are technically a legume) with enthusiasm.

Nuts are a popular plant-based protein source and are often used in dairy analogues like nut milk and nut cheese. And a variety of nut butters have emerged, beyond traditional peanut butter. Yet, we’re only beginning to appreciate the enormous nutritional benefits that nuts give us.

So how healthy are nuts? What actually constitutes a nut? Are there any downsides to eating nuts? And what are the best ways to store and eat them?

Types of Nuts

Nuts come in many different shapes and sizes. But most of the different types of nuts fall under the tree nut category. As the name suggests, they grow on trees. But botanically, some of what we know as nuts may technically be fruits, drupes, or seeds.

In general, the word nut is used to describe a hard covering or shell surrounding a kernel or “meat” inside.

Some of the most common types of nuts include:

• Almonds
• Pecans
• Walnuts
• Hazelnuts
• Cashews
• Brazil nuts
• Macadamia nuts
• Pistachios
• Pine nuts
• Chestnuts

There are also a few other foods that have “nut” in their name that you may be wondering about. For example, are coconuts nuts? Coconuts are technically drupes because they have three layers: a smooth outer layer, a tough fibrous layer, and the fleshy part surrounding the middle.

Peanuts are also lumped into the nut category but are actually legumes. They’re the edible seeds of the peanut plant and grow underground rather than on a tree. But in terms of culinary usage, they’re very much nutlike.

Additionally, nutmeg does not come from a nut, but from a seed. Water chestnuts are actually roots or tubers. And corn nuts are still corn; they’re just roasted until they’re hard and crunchy like nuts.

Nut Nutrition

Nuts of all sorts have been an important food source for humans for centuries. In fact, it’s theorized that the discovery and inclusion of nuts in our diets may have helped shape our brains and intelligence.

This makes sense when you consider the walnut, especially. Walnuts resemble tiny brains inside a skull. As a result, they were often associated with brain health. But many different nuts have a variety of nutrients beneficial for brain health and beyond.

Nuts are a rich source of complex carbohydrates. Carbs in nuts vary, but cashews and almonds have some of the highest carbohydrate contents at 8.6 and 6.1 grams per one-ounce serving, respectively.

Nuts also contain a good amount of protein, which is why they’re often recommended as a protein source to include in a plant-based diet. Peanuts rank the highest in protein, followed closely by almonds, pistachios, and cashews.

Additionally, nuts contain fiber, contributing to satiety. Hazelnuts and almonds contain the most fiber per ounce at 3 and 4 grams, respectively.

Nuts contain both saturated and unsaturated fats. The high fat content in nuts also contributes to a relatively high amount of calories per serving. If you’re trying to manage weight, you may want to stick to some of the lowest-calorie nuts, such as raw chestnuts or cashews, or limit your portion to no more than one or two ounces per day.

Across the board, nuts also contain significant amounts of vitamins, minerals, and antioxidants. A one-ounce serving of cashews contains 1.9 milligrams of iron, a vital mineral for transporting oxygen in the blood. And almonds, cashews, and peanuts are all good sources of magnesium. A single Brazil nut can also provide an entire daily value’s worth of selenium.

So with all of that to consider, what is the healthiest nut? Opinions may vary, but walnuts have some of the highest antioxidant levels and are also one of the best plant-based sources of omega-3 fatty acids. And researchers found that walnuts had the greatest health benefits among all the nuts studied in PREDIMED, a landmark randomized clinical trial on the Mediterranean diet.

Health Benefits of Nuts Worth Knowing About

When it comes to the health benefits of nuts, there are many worth knowing about. It seems that, unless you’re allergic to them, all nuts might be good for you in one way or another.

Nuts and Heart Health

Epidemiologic studies have linked eating nuts with reduced rates of heart disease. And that’s extremely good news for everyone since heart disease is the leading cause of death worldwide.

A review on nuts and cardiovascular disease risk found that higher consumption of nuts worked out to a 19% reduction in disease incidence and a 25% reduction in death from heart disease. Researchers also found a correlation between nuts and lower risk of atrial fibrillation and stroke deaths.

What’s more, a Korean cohort study discovered that even just one 15-gram serving of nuts per week (about half an ounce) was associated with a lowered risk of high blood pressure.

Nuts and Diabetes

Relatedly, recent studies have also indicated that nut consumption may help manage or prevent type 2 diabetes.

Many people with type 2 diabetes also have some form of heart disease due to its metabolic impacts on the body. As a result, researchers used a systematic review to look at the blood lipid levels in people with type 2 diabetes. They found that both peanuts and tree nuts had an impact on total cholesterol and triglycerides in the diets of diabetes patients.

A 2021 meta-analysis of clinical trials also found that tree nut consumption reduced glucose levels and HbA1c levels in patients with type 2 diabetes.

Nuts and Brain Health

Walnuts do indeed look like little brains and may also help with brain health. A 2022 study in the journal Nutrients showed walnuts have a powerful protective effect against neuroinflammation. This is an important quality to have since neuroinflammation is directly linked to the development of neurodegenerative diseases like Alzheimer’s.

Another more recent review also suggests that nuts have a positive impact on cognitive health across the lifespan and may especially help prevent cognitive decline in older adults. In particular, walnuts were noted as the most promising nut in supporting cognition due to their omega-3 fatty acid content.

Nuts and Longevity

Speaking of being protective across your lifespan, a study of Seventh-Day Adventists (a religious denomination that emphasizes healthy living and a vegetarian diet) found that those who ate nuts at least five times per week gained, on average, an extra two years of life expectancy. The nut eaters also experienced a significant reduction in heart disease risk.

And perhaps most dramatically of all, a large-scale, 30-year-long study found that people who regularly ate one ounce of nuts at least seven times per week were 20% less likely to die for any reason, compared to those who avoided nuts in their diet.

Nuts and Cancer

Many nuts have also been linked to lower rates of certain cancers. Studies done on walnuts, in particular, have found that they appear to be particularly protective against breast and prostate cancers. Walnuts and many other nuts contain a number of potent nutrients that may help fight cancer and boost overall health. These nutrients include ellagic acid, a phytochemical, and gamma-tocopherol, an antioxidant and the major form of vitamin E — both of which have strong anti-inflammatory and cancer-protective effects.

Nuts and Erectile Dysfunction

A clinical study published in the International Journal of Impotence Research looked at what happened to men with erectile dysfunction (ED) who ate three to four handfuls of pistachios a day for three weeks. They experienced a significant improvement in blood flow through their private parts. The researchers concluded that three weeks of pistachios “resulted in a significant improvement in erectile function… without any side effects.” That’s pretty impressive, considering the side effects of prescription ED medications.

Results from the FERTINUTS trial, a study examining the impact of nuts on sperm quality, also had positive things to say. The consumption of 60 grams a day of mixed nuts versus no nuts at all showed a significant increase in sexual function and desire among men.

Disadvantages of Nuts

Despite all the impressive health benefits of nuts, there are a few things to consider when adding them to your diet.

Nut Allergies

Perhaps the most obvious downside to nuts is that many children and adults are allergic to them. Tree nut allergies are the most common type of food allergy. And most children with a tree nut allergy are allergic to more than one nut and do not usually outgrow their allergy — as is sometimes the case with other food allergens.

Although peanuts are botanically legumes and not tree nuts, there is also a significant crossover between peanut and tree nut allergies. Around 25–40% of people with a peanut allergy also have a tree nut allergy.

Both peanut and tree nut allergies can have a range of symptoms, from coughing and wheezing to indigestion to hives, and, most severe of all, anaphylaxis. Obviously, if you have a peanut or tree nut allergy, do not consume them.

The American Academy of Allergy, Asthma & Immunology (AAAAI) suggests that seeds (sesame, sunflower, or pumpkin) are often better tolerated in individuals with tree nut allergies. Coconuts, macadamia nuts, and pine nuts are also considered okay for many people with tree nut allergies since the former is botanically a fruit, and the latter two also fall under the seed category. Individuals should consult with their health care team to confirm these foods’ safety.

Nutrient Density

Nuts are some of the most nutrient-dense foods you can eat. This makes sense, considering they are a small package that has the potential to grow into a tree! But because they’re loaded with nutrition (and calories), a little can actually go a long way.

So what’s the recommended serving size of nuts? In general, current dietary guidelines recommend a 30-gram serving, or a little over an ounce. However, a handful has also been suggested as a valid (although, admittedly, not very scientific) nut serving size.

The one exception to this is Brazil nuts. Because a single Brazil nut can contain up to 96 micrograms of selenium, which is almost double the recommended amount, it’s probably best to only consume one to two Brazil nuts per day. Brazil nuts also contain barium, which can be toxic in large doses.

Antinutrients in Nuts

Because nuts and seeds contain the building blocks for new life, they also tend to come with protections in place to ensure that life succeeds. Antinutrients are plant chemicals that are meant to make a plant less tasty, to deter predators.

Nuts contain antinutrients like phytates, tannins, lectins, and oxalates. Antinutrients are so named because they interfere with the absorption of certain nutrients. So, is this a reason to avoid eating nuts?

Although antinutrients are controversial in the nutrition world, they aren’t the bad guy they’re often made out to be. As we’ve seen in this article, nuts have amazing benefits. On the other hand, many studies done on antinutrients examine them in isolation, which is not how they’re consumed.

Antinutrients are found in many plant foods, along with a variety of beneficial vitamins, minerals, antioxidants, and other plant compounds. In fact, their very inclusion may actually contribute to some of the health benefits seen in nuts and other plant-based foods.

So there’s no need to fear antinutrients in nuts. But if you do want to lessen your antinutrient consumption for whatever reason, you can do so by soaking nuts in water for 24–48 hours. Cooking, sprouting, or fermenting nuts also has the same effect.

For more on antinutrients, see our article, here.

How to Enjoy Nuts

Based on numerous studies, it appears that eating at least one serving of nuts a week, and potentially up to a serving per day, may lead to tremendous health benefits. But how you get those benefits is up to you.

You can enjoy nuts straight as a snack, with a sprinkling of salt or other seasoning, in trail mix or granola, or added to smoothies. Nuts also go well in a nut loaf or casserole, as a topping for salads, blended into nut milk, or prepared into nut cheeses, nut butters, or even pie crusts.

However, because nuts contain different types of fat, they’re prone to spoilage. Walnuts, in particular, are high in omega-3s and may go bad more quickly than other nuts. Fresh in-shell walnuts are best. If you’re a little adventurous, you can get a nutcracker and crack them yourself.

If you opt for shelled walnuts, store them in airtight containers in the refrigerator to prevent their oils from going rancid. According to the University of California Agricultural and Natural Resources, nuts will retain their nutritional and flavor quality for up to one year if stored in the refrigerator or two years in the freezer. You can find out how long each type of nut lasts by viewing this chart on Eat By Date. Throw out (or compost!) any nuts that smell or taste sour or bitter.

And, of course, a food is only as healthy as the company it keeps. When nuts are overly salted or laden with sugar or with artificial additives and flavorings, they lose much of their nutritional value and can become a less healthy choice.

Nut Recipes

Enjoy nuts of all varieties for breakfast, lunch, dinner, and dessert with these outrageously nutty and wonderfully delicious nut recipes!

1. Toasted Pistachio and Cherry Overnight Oats

Toasted Pistachio and Cherry Overnight Oats are a tasty way to get a healthy dose of powerful plant nutrients. Oats, cherries, chia seeds, and pistachios offer a great deal of fiber, protein, and healthy fats. Not to mention, cherries and pistachios are packed with nutrients to fight inflammation from their abundant phytonutrients, making this a nourishing breakfast that provides long-lasting energy and health.

2. One Sheet Spicy Almond Tofu and Green Beans

Creamy almond butter breathes new life into protein-packed tofu and crisp green beans. In this recipe, the green beans are brushed with Spicy Almond Sauce before baking alongside the tofu and onions for a sheet pan meal that is efficient and scrumptious. Once everything’s done baking, pile your ingredients on top of rice (or your favorite whole grain), drizzle more nutty almond butter sauce on top, and garnish with additional flavors and textures for a restaurant-worthy nut recipe!

3. Fudgy Chocolate Chip and Walnut Brownies

What’s better than a warm fudgy brownie? If you guessed a warm fudgy brownie with walnuts, you’d be correct! These Fudgy Chocolate Chip and Walnut Brownies may seem too good to be true, but you certainly can have your (plant-based) cake and eat it, too. Made with fiber-rich oat flour, dairy-free, fair-trade dark chocolate, applesauce, and mashed banana, these brownies will have you coming back again and again. With dense gooey chocolate, crunchy walnuts, and a fudgy texture, these brownies are a naturally sweet treat you’ll be excited to sink your teeth into!

You’d Be Nutty to Ignore Nuts!

No matter what type of nuts you enjoy, you will find beneficial qualities in them. Nuts are nutritional powerhouses providing a potent source of plant-based protein as well as healthy fats, vitamins, minerals, and antioxidants. Their robust nutritional profiles also explain why they’re so good for you. From protecting your heart health to prolonging your life to even helping you out in the bedroom, nuts have a lot to offer.

And while there are a few downsides of nuts to consider, overall, the benefits far outweigh any drawbacks (unless you’re allergic, of course). From homemade nut butters to salad toppings, nuts offer a versatile and convenient way to elevate both taste and well-being, making them an indispensable addition to a health-conscious diet.

The post Nut Health Benefits: You Won’t Believe How Good They Are for You appeared first on Food Revolution Network.

Those are all well and good, but what would seriously make my day is an Olympic event highlighting the foods that do the most to support health and longevity.

If I were a betting man, I’d put my money on the benefits of turmeric to win the gold. And that would be fitting since turmeric is known in India as “haldi,” the Golden Spice. It earned its nickname not just from its bold yellow-gold color but its associations with prosperity, purity, and good fortune.

In India, powdered turmeric features prominently in a traditional pre-wedding ceremony. Turned into a yellow paste, it’s applied liberally to the bride and groom’s bodies to bring them good fortune and ward off the evil eye. Unmarried friends and family members may also benefit, as whoever gets touched by the paste will supposedly find an attractive partner soon.

In addition to its ritual uses, turmeric has been revered in India for its powerful medicinal properties for over 4,000 years. A mainstay of Ayurveda, the Indian healing tradition, as well as Traditional Chinese Medicine, turmeric is now being extensively studied by modern science for its potential health benefits.

In fact, it’s thought that turmeric may be one of the most potent anti-inflammatory compounds ever examined. And preliminary evidence suggests it may reduce the risk of just about every major chronic condition.

As a result, turmeric has achieved virtual superfood status in the industrialized world, bottled into a variety of supplements. But is it effective in supplemental form? And if you get it through food, how much is enough? Can you get too much? And should you be concerned about lead exposure?

Let’s dive into the world of turmeric and explore the evidence about the health benefits and risks of the Golden Spice.

What Is Turmeric?

Turmeric, or Curcuma longa to botanists, is a plant in the ginger family (called Zingiberaceaea, which would get me knocked out of a spelling bee if I didn’t have it written out in front of me). Other members of that family include galangal and cardamom.

Turmeric is native to Southeast Asia, where it’s now grown commercially (primarily in India) and used as a cooking spice.

There are over 50 different cultivars of turmeric, with the most common being the Madras and Alleppey varieties.

The culinary part of the plant is its rhizome (underground stem). Think gingerroot, just a bit skinnier and a whole lot yellower. As a spice, turmeric has a slightly bitter, pungent, and nutty taste. And its intense hue can range from yellow to gold to orange. It’s the main spice in many curry powders and the one that gives them their distinctive color.

Turmeric has both culinary and medicinal uses. Around the world, almost one billion people use it daily as a cooking spice. You can eat the rhizomes whole, either cooked or raw. And you can also use them dried and ground into a spice powder. In addition to its culinary uses, turmeric is also used as a preservative for food and as a coloring agent for mustards.

Turmeric and extracts made from it are also consumed as a supplement, orally in capsule or liquid form, or even as a paste.

Turmeric Nutrition

Like a lot of other spices, turmeric is a rich source of many essential minerals. These include iron (the nonheme variety that doesn’t build up in blood), copper, manganese, zinc, magnesium, and potassium. Fresh turmeric also delivers a small amount of fiber.

Turmeric’s big claim to fame, though, is its curcuminoids — the compounds that give the root not just its yellow color but also many of its health benefits. The main curcuminoid is curcumin, which, despite its name, doesn’t come from cumin. Curcumin is a polyphenol, a plant compound that acts as an antioxidant in our diets and has disease-fighting properties.

For more on polyphenols, check out our full article here.

The Benefits of Turmeric

At the top of this article, I said that turmeric could win a gold medal at the Nutrition Olympics. Let’s look at the evidence that leads me to give the spice a 10 out of 10.

Turmeric Anti-Inflammatory Benefits

Curcumin is often used as an anti-inflammatory agent in Ayurveda and Traditional Chinese Medicine. And many studies have put this application to the test.

A 2019 article reviewed test-tube and animal studies where curcumin showed protective effects against several gastrointestinal problems that were caused or worsened by inflammation (our view on the use of animals in medical research is here). These included acid reflux, Barrett’s esophagus (where the esophageal lining experiences damage from acid reflux), and H. pylori infection of the stomach.

Curcumin has also shown promise in reducing the effects of inflammatory bowel disease (IBD). It seems to work by helping to calm cells that are involved in inflammation. As a result, it’s theorized that curcumin could be a treatment option for reducing IBD flare-ups.

A 2021 meta-analysis also found curcumin to be effective in lessening the pains of rheumatoid arthritis (RA) by reducing inflammation, swelling, and pain. Included among the results was a 1980 study out of Iran that found curcumin supplementation helped reduce morning stiffness and joint swelling in human patients with RA.

Turmeric and Blood Sugar

Curcumin also shows great promise in treating and perhaps even preventing type 2 diabetes. A 2021 meta-analysis provided evidence that the compound may achieve these results by reducing inflammation and blood sugar levels.

And a 2023 meta-analysis of human trials found that turmeric can help lower blood sugar and hemoglobin A1c levels in people with type 2 diabetes. Unlike many diabetes drugs, however, the side effects of turmeric were positive. They included lowering total and LDL cholesterol, triglycerides, blood pressure, insulin resistance, and markers of inflammation. The results appeared to be dose-dependent — that is, the more turmeric people consumed, the greater the effects.

Turmeric and Brain Health

Because of curcumin’s anti-inflammatory and other beneficial properties, it’s being studied as a potential treatment for Alzheimer’s and other neurodegenerative diseases. The challenge is to deliver the curcumin in a way that enables it to easily cross the blood-brain barrier. Researchers are trying to make the compound more bioavailable by binding it to “carrier molecules.”

A 2022 review article reports that curcumin may also help people with early-onset Alzheimer’s lessen the sleep disturbances that often accompany the disease. This is important because your body requires quality sleep to “do maintenance” on the brain and clean out harmful substances — so Alzheimer’s and poor sleep make for a vicious cycle of increasing brain damage.

Turmeric and Cancer

Research shows that curcumin can help prevent the initiation of cancers and slow their development once they’ve occurred. How does it do this? Researchers believe that its anticancer mechanisms include inhibiting cellular growth, reducing the invasion and migration capabilities of cancer cells, enhancing programmed cell death, reducing inflammation, and favorably altering the intestinal microbiome.

Based on studies of which molecules curcumin targets in cancer cells, it may be that curcumin could be particularly effective in combating prostate cancer, colorectal cancer, and head and neck squamous cell cancer.

And according to a 2020 review article, several studies suggest that adding curcumin to chemotherapy treatment regimens enhances the efficacy of both chemotherapy and radiotherapy. This combination may extend the survival times of patients, boost the levels of proteins that prevent the spread of cancerous tumors, and alleviate adverse effects.

Turmeric and Heart Health

A 2017 meta-analysis found that the curcumin in turmeric might help lower LDL (“bad”) cholesterol and triglycerides in the blood. It seems particularly effective in reducing cholesterol levels in people with metabolic syndrome — a cluster of conditions that increase the risk of heart disease. While much research has focused on curcumin, some studies also suggest that whole turmeric may be even more effective at lowering cholesterol than supplemental curcumin alone.

There are several conditions that increase the risk of cardiovascular disease. And these conditions all share several underlying factors: oxidative stress, impaired mitochondrial function, metabolic irregularities such as changes in lipid levels and glucose processing, as well as inflammatory responses. Curcumin demonstrates a wide range of effects that target these particular factors, suggesting that it could reduce the risk of heart disease in some of the most vulnerable populations, including elderly people as well as those who are obese and/or have type 2 diabetes.

Curcumin Bioavailability

To recap, science has recognized what many cultures have known for centuries: Turmeric has powerful medicinal properties that can help treat a wide variety of diseases and conditions. But much of the data and recorded health benefits of turmeric have been based on studies that used supplements and extracts of curcumin rather than whole turmeric root or turmeric powder.

This creates a challenge because we know that human bodies aren’t great at absorbing curcumin, either from food or in supplemental form. That’s because curcumin is what’s known as hydrophobic, which doesn’t mean it’s afraid of swimming pools. Rather, it’s very poorly absorbed in water, which makes it hard for your body to get the compound into your cells where it can do good. That means the underlying science is unavoidably muddy since it’s hard to know what dose of curcumin a patient has absorbed. You can only tell the amount given.

Fortunately, researchers have begun finding proven ways to increase curcumin’s bioavailability.

1. Turmeric and Black Pepper

When you eat dishes that contain turmeric, you can absorb more curcumin if you add black pepper. This gives you the synergistic compound piperine, which significantly enhances the serum concentration, absorption, and bioavailability of curcumin. One study found that people who ate piperine along with curcumin absorbed 20 times more of the curcumin than people who didn’t receive black pepper. (If you’re looking to make this sound impressive, you can also say that black pepper increases curcumin bioavailability by 2,000% — which is just a fancy way of adding two zeros and a percent sign.)

You can take advantage of this finding by following Dr. Greger’s advice: Every day, consume a quarter teaspoon of dried turmeric with a pinch of black pepper.

2. Eat Turmeric with a Healthy Fat

Another way to increase the bioavailability of curcumin is to eat a healthy fat along with your turmeric. That’s because, while curcumin isn’t very soluble in water, it gets along really well with fat. Traditional Indian cuisine reflects this insight, as Indian dishes that include turmeric are often cooked with coconut milk, vegetable oil, or ghee.

If you want to stick to whole plant foods, remember that nuts, seeds, and avocados are generally good sources of healthy fat that can increase curcumin bioavailability as well.

Here are some of our favorite turmeric-containing recipes to help you get more of the Golden Spice into the cells of your body.

3. Curcumin Supplements

Researchers have also found ways to increase the bioavailability of supplemental curcumin.

Nanoparticle Curcumin

One is by encapsulating the curcumin in nanoparticles, which are just like regular particles, but a lot more nano.

Okay, okay. I’ll look it up for you: Nanoparticles are very (very, very) small particles measured in nanometers, and a nanometer is one-millionth of a millimeter. The thing about nanoparticles is that at that size, they behave differently than larger particles, both on a physical and chemical level. And one of those differences is in the way they can dissolve in water while protecting the curcumin they’re surrounding.

Micellar Curcumin

A second technique for increasing the bioavailability of supplemental curcumin is to chemically change it to a micellar form. Micelles are very small lipid molecules that act as a carrier for fat-soluble curcumin and make it water-soluble, which allows the curcumin to sneak in, so to speak.

But does that actually work? Well, to put it to the test, researchers conducted a study, published in Molecular Nutrition & Food Research in 2014. They gave participants a 500-mg dose of curcuminoids in either a native curcumin powder, micronized powder, or liquid micelles, and then measured blood levels of curcuminoids in the 24 hours that followed. The researchers found that, compared to the native curcumin, the micronized powder conferred a 9-fold increase in absorption. That sounds pretty impressive until you hear about the winner — the liquid micelle format, which led to a 185-fold increase.

In their discussion, the researchers also compared their bioavailability results with those found in other studies on bioavailable curcumin forms, including the use of the piperine found in black pepper (which led to a 20-fold increase in bioavailability), turmeric essential oils (which had a 7-fold higher bioavailability), and curcumin incorporated into lecithin (which conferred a 4-fold better absorption). They called micellar curcumin’s 185-fold result “unrivaled.”

Liposomal Curcumin

A third method of increasing bioavailability is to create liposomal conjugated curcumin. Liposomes are tiny spherical structures made up of lipid bilayers that can carry therapeutic agents like drugs or natural compounds. Like micellar curcumin, liposomal curcumin has an outer membrane that bonds with water, which allows the fat-loving curcumin inside to enter human cells more readily.

Downsides & Risks of Turmeric

The way curcumin is vying for that nutritional gold medal, you might think that the more of it you get, the better. But there are several reasons to be cautious about overconsumption of the Golden Spice.

Human studies on the effects of turmeric as a food have looked at doses ranging from less than 1/16th of a teaspoon a day up to about 2 tablespoons a day. And participants have taken these amounts sometimes for more than a month.

And while traditional Indian diets may include as much as a teaspoon of turmeric per day (or about an inch of fresh turmeric root), supplemental forms of curcumin with enhanced bioavailability could deliver the equivalent to cups of turmeric — definitely not a dose that you could achieve by eating real food.

According to the European Food Safety Authority and the World Health Organization, the acceptable daily intake value of curcumin is 0–3 milligrams per kilogram of body weight. So someone weighing 150 pounds (68 kilograms) is advised to limit their consumption to 204 milligrams of curcumin per day, or approximately 1 tablespoon. Although curcumin has been found to be safe at doses of 8 grams per day in both phase I and phase II clinical trials, there is some concern that very high doses, perhaps especially when combined with enhanced bioavailability, could lead to some side effects.

Turmeric Side Effects

Too much turmeric might possibly be able to cause DNA damage — at least, that’s what researchers have found in test-tube studies. So people who are pregnant, in particular, may want to moderate their turmeric consumption. High-dose curcumin also appears to thin the endometrial lining, which can interfere with in vitro fertilization.

Turmeric helps the gallbladder pump more vigorously, which is one way it can protect the liver and even prevent gallstones. But if there’s already an obstruction in the bile duct, those additional gallbladder contractions can cause a lot of pain.

Moderating turmeric consumption may also be a good idea for people with a predisposition to forming kidney stones. That’s because turmeric is high in oxalates, which can bind to calcium to form calcium oxalate, the key ingredient in about 75% of all kidney stones. (Some curcumin products, however, contain little to no oxalate.)

And in some people, high doses of turmeric may also cause gastrointestinal problems, including diarrhea, constipation, flatulence, and nausea.

Turmeric can also act as a blood thinner, which means it may interact with several classes of medications, including blood thinners, aspirin, and diabetes drugs.

Lead in Turmeric

There’s one more issue with turmeric that isn’t about the plant itself, but its preparation.

Turmeric powder from Bangladesh and India sometimes contains lead chromate, which enhances the spice’s appearance by making it a brighter shade of yellow. Which is to say, some turmeric powder is contaminated with lead.

There’s no safe level of lead; it can seriously damage reproductive, neurological, and cardiovascular systems — especially in children. If you want to protect yourself and your family from possible lead contamination, the best option is to buy fresh turmeric root or to buy organic turmeric and curcumin products.

To be extra safe, you can contact manufacturers to ask if they test for lead and other metals. California’s Proposition 65 seeks to protect, or at least inform, consumers by providing warnings about lead in foods like ground turmeric.

Use Turmeric in Good Health — Thoughtfully

Turmeric, the Golden Spice, has long been venerated in India and other Asian countries for its vibrant hue, culinary appeal, and medicinal qualities. Rich in curcuminoids, turmeric boasts antioxidants and disease-fighting polyphenols, making it a superfood of immense value. And modern scientific studies are confirming and highlighting its anti-inflammatory properties, brain-boosting effects, and potential for managing conditions like diabetes, cardiovascular disease, and cancer.

Despite all those beneficial properties, turmeric comes with some concerns. While supplements promise convenience, their proper usage and dosage require consideration. And potential lead contamination concerns may lead some people to make sure their turmeric is grown organically or comes in a tested supplement, rather than dried and powdered. As with many medicinal spices, moderation and informed sourcing is key.

In the “at least things haven’t gotten worse” department, the price of food and other essentials stabilized somewhat but remains well above what it was pre-pandemic. Factors maintaining high prices include the continuing effects of the pandemic on the food chain and the impact of the Russia/Ukraine war.

Meanwhile, climate chaos (a phrase that’s much more accurate than the anodyne “climate change” or “global warming”) is already causing havoc, contributing to higher food prices by bringing droughts to some places and floods to others, leading to crop failures and economic hardship.

In many parts of the world, climate chaos will continue to hamper food production, particularly in areas suffering from prolonged drought and relying more and more on groundwater — leading to accelerated aquifer depletion. This threatens to create massive disruptions when wells run dry — something that’s already happening in many places and is likely to intensify dramatically in the years ahead.

I was stunned by a recent opinion piece in the New York Times about Uzbekistan’s disappearing Aral Sea. A photo accompanying the article shows rusted boats stranded in a lifeless desert that used to be a thriving port — now 75 miles from the nearest body of water.

All these developments highlight the critical importance of eating lower on the food chain. Doing so can save massive amounts of land, water, and other natural resources — and can significantly reduce the food system’s contribution to climate chaos.

And, as we frequently discuss on this site, eating more plants, fewer animals, and less processed food can also be a great move for your health.

In short, the mission of the Food Revolution Network is more important than ever.

“With WHOLE Life Club, I sought support and information to help me on my journey to a…  whole food, plant-based diet. It has done that and a whole lot more! I have lost over 120 pounds since September 2022. My A1c dropped from 10.4 to 4.5, my triglycerides are now in a normal range, my LDL cholesterol has dropped tremendously, and my HDL cholesterol is in a healthy range and creeping higher. I feel so much better, with more energy, motivation, and a healthier mindset. Thank you to WLC and all its members! I enjoy how positive everyone is, and the nonjudgmental way the leaders include everyone as they teach, no matter what phase students are in on their journey.”

Plant-Based Coaching Certification graduate Terry Baker from Oro Valley, AZ, USA, wrote:

“Food Revolution Network’s Plant-Based Coaching Certification was truly the answer to my prayers, and I am so eternally grateful. I value the PBCC so highly because not only did I learn about the vast intricacies of the human body and exactly what it needs to be truly healthy at any age, but also I gained the knowledge and confidence to successfully share this vital information with others, hoping to end unnecessary suffering and disease. Do not hesitate in taking this course! You have no idea what a beautiful, powerful, and positive impact you could have in this world! Thank you to EVERYBODY in the Food Revolution Network for making this course possible.”

The Future of Plant-Based Eating

More and more people around the world are showing an interest in moving toward a more plant-based diet, and the number of people who make the shift is also increasing.

Veganuary — a fun portmanteau of vegan and January — broke all previous records with more registered participants than ever, from nearly every country in the world. And many of those folks maintained a more plant-based diet after the 31 days of the event.

More and more restaurants, businesses, and other organizations are responding to an increased demand for plant-based options — and sometimes leading it — by cutting down on animal products or eliminating them altogether. NYC Health + Hospitals, which operates 11 public hospitals in New York City, now serves plant-based meals to inpatients by default. Not only are the meals healthier than before, but they’re also changing perceptions of how “hospital food” tastes — with chefs creating dishes inspired by Latin American, Asian, and other cuisines representing the populations served by these institutions.

In a move that might have seemed unbelievable just a few years ago, the US Conference of Mayors (a nonpartisan organization that includes the mayors of all 1,400 US cities with populations of 30,000 or more) ratified a resolution supporting a plant-based approach to fighting the epidemic of chronic disease, mitigating climate chaos, and saving money desperately needed by the municipalities.

The number of restaurants offering plant-based menu options is also increasing. According to research by the Plant Based Foods Association, 95% of restaurants that offer plant-based selections expect sales of those items to remain steady or increase. And four times as many foodservice operators were planning to add plant-based options as the number that were planning to remove them.

A student-led campaign in the UK, Plant-Based Universities, is working to get all university catering facilities to transition 100% of their menus to plant-based. Begun in late 2021, the campaign has given a voice to students who are voting to remove animal products from university food halls specifically to address the climate crisis.

And in the US, Representative Jim McGovern of Massachusetts won our “best acronym” award by introducing the Peas, Legumes, and Nuts Today (PLANT) Act in the House of Representatives on July 28, 2023. If passed, the act would establish an Office of Plant-Based Foods and Innovative Production at the United States Department of Agriculture (USDA), and help fund farmers who produce ingredients specifically for plant-based foods, like legumes and mushrooms. It would also create a research program to further the development of plant-based proteins that could replace meat and offer technical and financial assistance to businesses that move the food industry in a more plant-forward direction.

Plant-Based Diets Continue to be Better for Your Wallet, Health, and the Planet

One of the nice things about advocating for more plant-based eating is that it tends to make people’s lives better right away — starting with their wallets. A study by the Physicians Committee for Responsible Medicine found that adopting a low-fat vegan diet led to a 16% reduction in grocery bills, for an average savings of $500 per person per year.

If you’d like to avail yourself of the economic advantages of a plant-based diet, a good place to start is our article 7 Healthy Recipes for Eating Plant-Based on a Budget.

While the benefits of a whole foods, plant-based diet to your pocketbook can be felt immediately, it might take a few days, weeks, or months to notice health improvements. But scientific research continues to find more and more evidence that such improvements are likely.

A 2023 study published in the American Journal of Lifestyle Medicine followed 59 patients with type 2 diabetes as they were placed on a low-fat, plant-predominant diet for six months, along with receiving standard medical treatment. By the end of the study, 37% of the patients, whose average age was 71, had their diabetes in remission.

A 2023 study published in the journal Nutrients looked at how diet, genes, and lifestyle factors contribute to obesity by analyzing body fat in adults. Researchers discovered that a plant-based diet helped reduce the risk of obesity, even for those with a genetic predisposition to higher body fat.

Another article published in the past year collected data from 55 recent human trials on the effects of a plant-based diet on cardiovascular disease. The authors wrote that the preponderance of evidence showed that incorporating more plant foods into the diet can protect against heart disease and may also help prevent other chronic conditions.

Plant-based eating, especially a diet rich in whole foods, was also found to be predictive of mental health. A 2023 study found that a high-quality plant-based diet may offer protection against depressive symptoms and should be considered as a lifestyle-based treatment for people suffering from the condition.

And in November 2023, the results of a carefully conceived and remarkable randomized controlled trial involving 22 pairs of identical twins were published in JAMA (Journal of the American Medical Association) Network Open. The study authors concluded: “The findings from this trial suggest that a healthy plant-based diet offers a significant protective cardiometabolic advantage compared with a healthy omnivorous diet.”

What About the Earth?

One of the major drivers of the trend toward more plant-based eating is increased awareness of the scope of the chaos wrought by human-made climate change. While switching to electric vehicles and replacing energy-guzzling appliances with more efficient ones are steps in the right direction, the impact of these actions pales in comparison with the effects of adopting a plant-based diet.

Research published in the prestigious journal Nature in 2023 found that, on average, vegans produce 75% fewer food-related greenhouse gas emissions than meat-eaters. And plant-based dietary patterns also reduce harm to land, water, and biodiversity.

Becoming a B Corp

Speaking of impacts on the world around us, we wanted to share some exciting company news about FRN. In 2023, FRN submitted an application for B Corp status with high hopes that the submission will be approved in 2024 (our Owners and Board members are Ocean Robbins and John Robbins, as you might guess).

A B Corp, or benefit corporation, is a type of company that’s recognized for meeting higher standards of social and environmental performance, accountability, and transparency. B Corps are committed to generating positive impacts on society and the environment.

The application process includes an extensive review of the company’s mission and where its impact is and is not aligned with that mission. The review looks at things like donation of money, products, or services to social causes and at-risk communities; decreasing pollution, greenhouse gas emissions, and production of waste; use of renewable energy and resources; support of tree planting and other forms of carbon sequestration; equitable compensation of team members; integration of mission-related responsibilities into employee performance evaluations and job descriptions; and providing employment and advancement opportunities for women, people of color, and other traditionally marginalized groups.

Since we started FRN in 2012, our mission has been front and center. We’re committed to healthy, ethical, sustainable food for all! So becoming a certified B Corp seems to be a natural next step to formalize our values.

On a Personal Note

In 2023, my dad, colleague, and dear friend — and FRN cofounder — John Robbins, experienced the progression of a health condition, post-polio syndrome, that has had a significant impact on his life and on our family. He is working with it in a profound way, and we shared about it in this video. We have received nearly a thousand deeply moving responses to this sharing, and they have lifted our family’s spirits. The way my dad is working with this condition is profoundly moving to me — and to many other people, too.

My dad and I are profoundly privileged to work with an amazing team of 25+ at FRN. This is, without a doubt, the most friendly, cooperative, dedicated, accountable, and effective team either of us has ever been a part of. The FRN team works virtually, and as much as digital tools like Zoom and Slack allow us to collaborate and be in each others’ lives, they aren’t a perfect substitute for in-the-flesh human interaction. So I’m delighted to share that in October 2023, we hosted our first in-person team retreat since 2019.

Thank You for All that YOU Do

We work hard at FRN, and sometimes the mission that we’ve staked out, along with the tasks and deadlines that bring that mission to life, can feel daunting. So it’s important for us to constantly remind ourselves that the food revolution movement is a mission much bigger than my dad, much bigger than me, much bigger than any one person, and much bigger than the FRN staff. It’s a movement that is growing and gaining traction, saving lives and bringing healing to our world.

And that movement includes you, about whom I’ve saved the last word.

FRN has a voice and influence because of you. When famous and influential people and brands consider whether to partner with us, one of the things they look at is our “reach.” Because we’re over a million members strong, we can work with the folks who gave the world movies like Fantastic Fungi and The Need to GROW. We can interest a book publisher like Hay House in publishing our cookbooks (with another coming back for final editing next week for publication in 2024).

We can attract an all-star lineup to share their ideas in our annual Food Revolution Summit because they know that a huge audience is there to “eat up” their wisdom — and use it to improve the lives of themselves and their loved ones, their communities, and the entire world.

There’s a video that was published in 2009 on YouTube that went viral and has now amassed over 24 million views. Titled “Sasquatch Music Festival 2009 — Guy Starts Dance Party,” it’s a 3-minute clip showing a lone dancer doing a series of pretty goofy moves. After a while, he’s joined by his first follower and then a second. A little over one minute into the video, it suddenly turns into a dance party — a mass movement. The energy grows and becomes contagious. When I first watched it, I wanted to jump through my laptop screen and join in.

Without you, dear reader, my dad, our staff at FRN, and I would still be the first three dancers, enjoying ourselves but lacking impact at scale. Your willingness to embrace the mission and the frequent calls to action — and to share and amplify the messages and make them your own — is what allows us to make the contributions highlighted above.

So please know how absolutely grateful we are to you for all the ways you generously support our work and provide loving and helpful feedback to help us improve. And for all the ways you assume leadership in your families and communities, day in and day out.

Like: Moving toward a plant-based diet. Choosing organic produce when you can. Buying local, from farm stands and farmers markets. Buying less and loving more. Donating to worthy causes. Loving the people you love with your whole heart. Trying new healthy recipes from our blog articles. Sharing articles, films, and healthy food with friends and loved ones.

Thank you, thank you, thank you!

Thank you for caring about the food that you eat and the food you share with others. Thank you for caring about the well-being of the people who produce that food.

Thank you for aligning your actions and purchases with your values, and for being willing to look at inconvenient truths and adapt your behavior accordingly.

Thank you for all the ways in which you strive to be the change we all wish to see, and to manifest, in the world.

Here’s to all we accomplished together in 2023, and to the healing, compassion, and beauty we’re creating, one meal at a time.

May all be fed. May all be healed. May all be loved.

Ocean Robbins and John Robbins

The post Looking Back: Food Revolution Network’s 2023 Year in Review appeared first on Food Revolution Network.

The collapse didn’t happen, thanks to, depending on what you believe, the hundreds of millions of dollars spent upgrading code in the late 90s (whoops, 1990s) or because there was never any real risk of calamity.

But the hype — some would say hysteria — that gripped many as January 1, 2000, was approaching forced the world to consider what would happen if our information networks shut down. Now, imagine if those information networks were inside your body instead.

Your nervous system is kind of like a miniature version of the internet. Your bodily tissue (or fascia) contains approximately 250 million nerve endings, all of which are continuously gathering and sharing electrical impulses back and forth between your brain and the rest of your body. When everything works well, you can just go about your day without giving your nerves a second thought.

But when even a few of those quarter billion nerve endings are damaged or otherwise dysfunctional, you may experience a cascade of calamities throughout your body. Damaged nerves can’t deliver electrical signals optimally, or in some cases at all. This dysfunction can cause pain and a number of other symptoms, including the sensation of pins and needles, muscle problems, and even loss of normal bodily functions like digestion and breathing.

The word for this kind of nerve damage is neuropathy.

Many neurologists recommend surgery or medications as first-line treatments for neuropathy, and in fact, many advanced cases can benefit from this approach. But there’s evidence that some neuropathies, especially in their early stages, could benefit more from what’s in your pantry than what’s in your medicine cabinet.

In this article, we’ll look at neuropathy nutrition and the relationship between what we eat and nerve health.

What Is Neuropathy?

Neuropathy is the medical term for damage to nerves outside of the brain and spinal cord. This damage can cause pain, numbness, weakness, and other uncomfortable and sometimes dangerous symptoms. It’s also called peripheral neuropathy, as it disproportionately affects nerve endings that are located closer to the body’s extremities than the core.

Neuropathy can mess up nerve signals in three ways. It can lead to complete loss of signaling, inappropriate signaling, or distortion of the messages that are sent.

If only one nerve is affected, that’s called mononeuropathy. A common mononeuropathy is carpal tunnel syndrome, which is often caused by repetitive use damage to the median nerve of the arm. Polyneuropathy, which involves multiple nerves (and not talking parrots), is the more common condition.

Types of Neuropathy

There are also subcategories of neuropathy, named for the nerve function they affect.

Motor Neuropathy

Motor neuropathy interferes with the movement of the muscles typically under conscious control, such as those used for walking, grasping things, or talking. Examples include muscle weakness or shrinking, or uncontrollable muscle twitching (which is also called fasciculation).

Sensory Neuropathy

Sensory neuropathy interferes with the transmission of sensory data from the extremities to the brain, such as temperature, the pain from a paper cut (ouch!), the feeling of a light touch, or information about the location of limbs in relation to one another. This can lead to loss of reflexes, coordination, or balance; burns or infections because there’s no impulse to pull away from a hot stove or clean a wound; and feeling pain from stimuli that aren’t actually harmful, such as the weight of a blanket on the feet.

Autonomic Neuropathy

Autonomic neuropathy impairs the brain’s ability to regulate activities that people do not control consciously, such as breathing, digesting food, and heart and gland functions. People who suffer from this type of neuropathy can experience heat intolerance and excessive sweating, light-headedness from low blood pressure, and vision problems, among other things.

Proximal Neuropathy

Proximal neuropathy is a type of nerve damage centered in the hip, buttock, or thigh. It usually causes pain in just one side of the body.

Focal Nerve Neuropathy

Focal nerve neuropathy affects a single nerve and may cause symptoms such as double vision, weakness on one side of the body, or partial paralysis, and associated pain. This type most often targets nerve endings in the legs, hands, head, or torso.

What Causes Neuropathy?

There are more than 100 different conditions, both inherited and developed, that can lead to neuropathy. But a few of them cause the vast majority of cases.

Neuropathy and Diabetes

Diabetes, both types 1  and 2, commonly causes neuropathy. That’s because high glucose levels can damage the small blood vessels that supply your nerves. As those nerves cannot access the nutrients they need, their fibers suffer damage and they may eventually die. At this writing, there’s no known way to reverse the damage once the nerves have atrophied. But there are many ways to prevent and reverse prediabetes and type 2 diabetes. (I hosted a whole masterclass on the topic with diabetes expert Brenda Davis, RD — to watch it for free click here.)

Neuropathy and Autoimmune Diseases

Autoimmune diseases cause harm by attacking the body’s own cells and tissues as if they belonged to a foreign invader. Two autoimmune conditions that target the nerves include Guillain-Barré syndrome and celiac disease.

Guillain-Barré syndrome typically presents after a gastrointestinal or respiratory infection, or following a vaccination. For some reason, the immune system responds to these challenges by starting to destroy the myelin sheath that surrounds the axons of many nerve cells. It can then progress to damaging the axons themselves.

Most people recover fully, a process that can last from a few weeks to a few years. But in some cases, the neuropathy progresses to paralysis that can threaten the ability to breathe.

The most common form of neuropathy that accompanies celiac disease involves both motor and sensory nerves. Other autoimmune diseases, including autoimmune thyroid disease, rheumatoid arthritis, systemic lupus erythematosus, and Sjögren’s syndrome, are linked to both neuropathy and celiac disease. Because the nerve damage appears to be triggered by exposure to gluten, symptoms may improve or even resolve on a gluten-free diet.

Neuropathy and Alcoholism

Neuropathy is among the most common negative side effects of chronic alcohol overconsumption. It typically shows up as pain, pins and needles, and lack of muscle control in the lower extremities. Alcohol, it turns out, directly poisons nerves. And the poor nutrition that often accompanies alcoholism is a separate risk factor for neuropathy. Patients who abuse alcohol also tend to consume fewer other calories, and their gastrointestinal tracts struggle to absorb the nutrients they do encounter.

Because alcoholism is a chronic condition, the neuropathy it causes may become permanent. But in cases that are caught early enough, stopping alcohol consumption may help improve neuropathy.

Other Causes of Neuropathy

Toxins other than alcohol can also cause neuropathy, among them mercury, certain types of toxic mold, and chemotherapy drugs. Injury and trauma can also induce neuropathy if it involves compression or crushing of a nerve, as can happen in automobile accidents, falls, sports, and even some medical procedures.

What Vitamins and Minerals Help with Neuropathy?

We know that certain vitamins and minerals are essential for healthy nerve function. And a lot of studies have looked at specific nutrients focused on supplemental forms and doses, but very few have looked at the impact of dietary nutrients on neuropathy. So it makes sense that one of the best ways to reduce your odds of developing neuropathy is to eat a diet rich in the nutrients known to nourish your nerves. But unfortunately, the evidence for this statement is a bit indirect and circumstantial. Therefore, let’s look at the specific nutrients that have been studied, remembering that all of these nutrients are available in foods as well as in supplements.

Vitamin B12

Vitamin B12 helps your body produce a substance called myelin that shields some nerves and helps them transmit information and sensations faster and more efficiently. You can think of them as the insulation on electrical cables and wires. Getting enough B12 is essential for your health, and specifically for the prevention of neuropathy, which is the most common symptom of B12 deficiency.

Supplementing with B12 (especially in plant-based eaters who have a harder time getting this nutrient from food) can improve peripheral neuropathy, including the forms that are primarily caused by diabetes.

For more on B12, including how to ensure that you’re getting enough along with the best plant-based sources, check out our comprehensive article: Vitamin B12: Why it’s Important and How to Avoid B12 Deficiency.

Vitamin B1

Vitamin B1, also known as thiamine, is also a critical nutrient for your nerves. Peripheral neuropathy can be caused by a B1 deficiency, something that’s seen as part of the cluster of symptoms associated with beriberi. That’s because B1 plays a key role as a coenzyme in carbohydrate metabolism, which is the main energy supply for nerve fibers. It also protects nerves from oxidative damage.

Supplementing (with food-based thiamine or with a synthetic analogue, benfotiamine) or eating foods rich in B1 can help prevent or treat deficiency and neuropathy. In severe cases, patients may need intravenous thiamine to relieve symptoms.

Vitamin B3

Another neurological superhero from the B-Vitamin Cinematic Universe is vitamin B3, aka niacin. B3 plays a key role in the development and survival of nerve cells. Studies of rats have shown that supplementation with this family of vitamins can protect against nerve pain and injury, preserve muscle function and vision, and lessen pain and discomfort. (Our view on the use of animals in medical research is here.)

For people who are dealing with ongoing neuropathy, B3 supplementation appears to help only when done in combination with other B vitamins. When neuropathy is associated with cardiovascular disease, there’s research indicating that B3 may work better in conjunction with statins.

For more on the B vitamin family, check out our article: What B Vitamins Do You Need — And What Are The Best Vegan Sources of B Vitamins?

Vitamin E

Your central and peripheral nervous systems are both big fans (and avid users) of vitamin E. Deficiency of this nutrient negatively affects both systems and can lead to peripheral neuropathy. That’s because not having enough vitamin E can cause changes in peripheral nerves and hasten the loss of a type of neuron known as a DRG cell. DRG — dorsal root ganglia — cells are of particular importance because they are afferent neurons, conveying information inward from the body to the brain and spinal cord.

A 2014 study found that vitamin E supplementation reduced neuropathic pain in patients with diabetes. And a 2021 study of people with peripheral neuropathy caused by chemotherapy also found that vitamin E supplementation was an effective treatment.

For more on vitamin E, including its health benefits and some possible risks of supplementation (spoiler alert: it’s probably better to get it from food than from pills!), read our article on Vitamin E Benefits: Why it Matters & the Best Places to Find It.

Magnesium

Magnesium is important for the nerves to transmit messages optimally, as well as for neuromuscular coordination. Magnesium plays a bunch of roles in the nervous system, including keeping overexcited nerve cells from self-destructing. In blocking a nerve receptor called N-methyl-d-aspartate (NMDA), magnesium both calms the nervous system and prevents pain hypersensitivity.

Patients with diabetic neuropathy also tend to have lower levels of magnesium in their blood. And a 2015 study of rats showed improved neurological function recovery and enhanced nerve regeneration with a high-magnesium diet.

Find out more about magnesium in our article: All About Magnesium: Health Benefits, Risks, & Magnesium-Rich Foods You Should Know About.

Omega-3s

Omega-3s are another nutrient group that’s essential for the development and maintenance of healthy nerves. They can help prevent the death of nerve cells and improve their function by chilling out pro-inflammatory and oxidative stress pathways.

A 2017 study that gave supplements of the omega-3 fatty acids EPA and DHA to mice showed that the supplementation sped up their nerve regeneration and, based on observations of a reduction of pain behaviors, reduced their pain as well.

A 2021 study of humans with diabetic neuropathy also found that the lower the plasma DHA levels, the more prevalent multiple neuropathies were. Giving the subjects omega-3 therapy led to greater nerve regeneration.

Find out more about omega-3s in our comprehensive article: Omega-3s: Why Are They Important — And What Are the Best Sources for Your Health?

Alpha-Lipoic Acid

Alpha-lipoic acid is an antioxidant that your body manufactures in the mitochondria (or energy center) of your cells. It works to eliminate reactive oxygen species (ROS), and helps with neuropathy by improving circulation and enhancing the dilation of blood vessels. It also helps suppress a cytokine called prostaglandin E2, which is a key compound involved in inflammation. By affecting several different pathways of oxidative stress, alpha-lipoic acid may reduce sensory neuropathy pain.

Recipes That May Help with Neuropathy

Increasing consumption of healing plant-based foods could be a wonderful and gentle support to anyone who is suffering from (or wants to avoid) nerve pain. With these tasty plant-based recipes, incorporating foods that contain supportive nutrients necessary for your nervous system can be enjoyable, simple, and nourishing for your nerves and your entire body.

1. Matcha Muffins

Whether enjoyed with your morning tea or as an afternoon pick-me-up, our Matcha Muffins are a testament to the idea that wholesome ingredients can be both delicious and supportive of your well-being. Made with oats, which contain a type of soluble fiber called beta-glucans, these muffins may aid in reducing inflammation and supporting overall nerve health. Their subtle sweetness and earthy undertones create a harmonious flavor blend that will satisfy your sweet cravings without the refined sugar.

2. Kale Caesar with Tofu Croutons

Kale Caesar with Tofu Croutons has many vital nutrients that can positively influence the health of your nerves. Kale contains sulforaphane, which may go a long way in reducing oxidative stress and inflammation, providing relief to those experiencing nerve damage and discomfort. The creamy Caesar dressing, nutty walnut parmesan, and crunchy tofu croutons are also brimming with nutrients such as B12, omega-3s, and magnesium — all essential for proper nerve functioning. This wholesome salad is a great go-to meal when you are looking for something consistent to enjoy in your journey toward improved nerve health.

3. Saffron Cauliflower and Chickpeas

Saffron may not be the first thing you think of when you consider natural remedies to help with pain relief, but it has actually been shown to have therapeutic effects for those living with neuropathy thanks to its anti-inflammatory properties. When combined with sulforaphane-rich cauliflower, this wholesome side dish will not only be a savory delight for you to enjoy but a nourishing experience for your nervous system as well.

Consider Your Diet When Dealing with Neuropathy

Healthy nerves require good nutrition. And without some specific nutrients, neuropathy can develop or become worse. For people with diabetes, it’s particularly important to eat a diet rich in nutrients, like fruits, vegetables, and whole grains, all of which contain compounds that act like superheroes for our nerves.

On the other hand, some foods, especially those high in sugar and saturated fats, act a bit like neuropathy villains, worsening the problem and causing additional suffering. Once you understand the connection between what’s on your plate and how your nerves feel and function, you can make choices to support your health and quality of life.

What do you do to stay alive and thrive in the face of all these challenges? If you answered “synthesize polyphenols,” then congratulations! You’ve just won this round of “Are You as Smart as a Plant?”

Polyphenols are a class of compounds (a huge class, actually, made up of at least 8,000 different ones that we know of) that are in a wide variety of plant foods. You may have heard of some of them, like resveratrol (found in grapes and red wine) and EGCG (featured in green tea).

Plants produce them as protection from various threats, including disease and sun damage. And animals who consume those plants can also benefit from polyphenols in similar ways.

As industrialized societies struggle to contain multiple epidemics of chronic disease, many medical experts and researchers are now pointing to polyphenols (and other nutrients found in whole, minimally processed plant foods) as powerful allies in preventing and treating a variety of chronic conditions.

So in this article, we’ll explore the world of polyphenols, including how they work in your body, their health benefits, and whether you should get them from food or supplements.

What Are Polyphenols?

Polyphenols are natural compounds found in various plants. Researchers consider polyphenols to be kind of “bonus” compounds, or in their jargon, “secondary metabolites.” This means they’re not directly involved in the growth, development, or reproduction of a plant.

Plants produce polyphenols as a defense mechanism against ultraviolet radiation and aggression from pathogens. But they aren’t purely defensive; they’re also deployed to attract pollinators.

From our perspective, polyphenols play a significant role in the flavors and health benefits that many plant foods offer. They can change the way plants taste, and determine their colors and aromas.

Polyphenols are also antioxidants, so their presence can keep plant foods from rotting (a trick known as “oxidative stability”). They also can help prevent oxidative stress in your body after you consume them, which can help stave off many types of disease.

There are several subfamilies of polyphenols, including flavonoids, phenolic acids, and lignans. In addition to resveratrol and EGCG mentioned above, another well-studied polyphenol is curcumin, found in turmeric root and powder.

What Are the Health Benefits of Polyphenols?

The “poly” in polyphenol means that all compounds in this family have multiple phenolic hydroxyl groups — but could just as easily refer to their ability to prevent and treat multiple health conditions.

Polyphenols and Cancer Prevention

Both test-tube and animal studies suggest that polyphenols can help prevent the initiation and progression of several cancers. They do this via a number of mechanisms, including inhibiting the proliferation and spread of cancer cells, suppressing tumor growth, preventing the formation of new blood vessels, and fighting inflammation.

Different classes of polyphenols exhibit different anticancer properties. For example, flavonoids, including quercetin and kaempferol, can inhibit cancer cell growth and induce cancer cell death. Resveratrol suppresses tumor growth, inhibiting metastasis and reducing angiogenesis. And curcumin, derived from turmeric, is multitalented; it’s anti-inflammatory, antioxidant, apoptotic, antiangiogenic — and a bunch of other words that don’t begin with A.

Many forms of polyphenols are also known to influence critical signaling pathways that are integral to the initiation, advancement, and spread of cancer.

And polyphenols aren’t just cancer fighters on their own; they’re also team players. Researchers have found that polyphenol combinations are more powerful than the effects of each one individually. For example, a mixture containing quercetin, curcumin, green tea, Cruciferex (a proprietary blend of polyphenols found in cruciferous vegetables), and resveratrol significantly inhibited the growth of a particular cancer of the head and neck.

Polyphenols and Heart Health

Polyphenols can also protect your heart in a bunch of different ways. They reduce cardiac inflammation and oxidative stress, support cell mitochondria in doing their job properly, and increase survival signaling (the ways cells talk to each other when they encounter a potential threat).

Some polyphenols have also been found to reduce the formation of blood clots, which decreases the risk of heart attacks and strokes. And the flavonoid family of polyphenols promotes the dilation of blood vessels, which helps lower blood pressure and improve blood flow — both of which help with cardiovascular health.

Polyphenols can also improve your cholesterol profile — specifically, lowering LDL and increasing HDL cholesterol levels, thereby reducing the risk of atherosclerosis.

Some polyphenols are not easily absorbed by your small intestine, but it turns out that these polyphenols can be metabolized by the microbes in your gut into compounds that contribute to cardiovascular health.

Impressed by these myriad beneficial mechanisms, some researchers are now studying therapeutic protocols for using polyphenols in medicine to prevent and treat cardiovascular disease.

Polyphenols and Diabetes

One of the most dangerous consequences of diabetes can be vascular disorders, where persistent high blood sugar levels cause damage to blood vessels through inflammation, oxidation, and cell death. Polyphenols can combat all three mechanisms. And scientists are exploring how to use them to modulate the expression of the genes involved in the development of vascular conditions.

Human and animal studies (our views on the use of animals in medical research can be found here) show that polyphenols can lower high blood sugar levels and enhance the body’s ability to secrete insulin quickly and respond to it effectively.

It appears polyphenols accomplish this via several mechanisms. They slow down how quickly your body absorbs sugar from the food you eat. And they encourage your pancreas to produce more insulin in response to carbohydrate consumption. They also regulate how much glycogen the liver releases into your blood in the form of sugar.

If all that wasn’t enough, polyphenols also help insulin receptors work more efficiently and help tissues absorb more sugar than they would otherwise.

Polyphenols also fight diabetes by helping to protect pancreas cells that produce insulin from damage due to high glucose levels. They also promote the growth of these cells and slow down their death.

Polyphenols and Osteoporosis Benefits

As you age, you lose bone mass — that’s natural. But your diet and lifestyle can significantly influence the rate at which that happens. In some people, the process accelerates due to oxidative stress messing with the living tissues in bone: the osteoblasts and osteoclasts that build and break down bone, respectively.

Since polyphenols are such powerful antioxidants, researchers theorized that eating berries (one of the richest food sources of the compounds) could help reduce bone loss due to stress and aging. And they might have been on to something because several studies have now shown that people who eat a lot of berries also have higher bone mass. Since the standard pharmaceutical treatments for osteoporosis have a high rate of serious side effects, there’s a lot to be gained by exploring how eating polyphenol-rich foods can help prevent or slow bone loss.

In addition to oxidative damage, it appears that bone loss can also be caused by inflammation. A 2019 literature review found evidence that polyphenol-containing foods like fruits, vegetables, tea, and soy may combat osteoporosis by reducing inflammation, thus allowing the body’s bone remodeling process to proceed without hindrance.

A 2023 study out of Korea also found concrete evidence for the link between high polyphenol intake and protection from osteoporosis. Researchers gave bone density tests and food intake questionnaires to 4,600 women and followed up with them for an average of five years. They found that the postmenopausal women who reported eating the most phytochemical-rich foods (i.e., those high in polyphenols) had a 16% lower risk of developing osteoporosis than those who ate the least.

Polyphenols and Brain Health

One of your body’s most important functions goes by the strange name autophagy, which literally means “eating oneself.” Instead of visualizing someone chomping on their own arm, however, think of your tissues constantly absorbing and discarding malfunctioning cells, proteins, and other bits and bobs that are no longer doing their jobs. This process in the brain is key in protecting you from neurodegenerative diseases such as Parkinson’s, MS, ALS, Huntington’s, Alzheimer’s, and other types of dementia.

Research shows that polyphenols support the brain’s clean-up process by removing misfolded proteins. They also reduce brain inflammation and stress, helping protect the brain from damage that can lead to neurodegenerative conditions.

Polyphenols are especially suited to supporting your cognitive health for several reasons. First, unlike many other nutrients, they can easily pass into your brain from your bloodstream (crossing that very finicky blood-brain barrier). Second, they help to remove harmful substances known as reactive oxygen species that can damage your brain cells. Third, they can capture and neutralize certain metal ions, such as copper and iron, that could be harmful to your brain in high concentrations.

But wait — there’s more! Polyphenols have another special brain ability: They can increase the amount of neurotrophic factors in your brain that promote the health and growth of your nerve cells. By attaching themselves to the receptors of these neurotrophic factors on the surface of nerve cells, polyphenols enhance the cells’ abilities to adapt, survive, multiply, and grow. It appears, in fact, that polyphenols can not only protect your brain from degeneration but may even support learning, memory, and other cognitive abilities.

Is There an RDA for Polyphenols?

Given how awesome polyphenols are, you might think that government bodies tasked with setting nutritional standards would have come up with a recommended daily allowance (RDA). But no such standard exists in the US because the compounds aren’t considered “essential” nutrients — that is, there aren’t any diseases specifically caused by a deficit, the way insufficient vitamin C leads to scurvy and not enough B1 inevitably produces beriberi.

Instead, not getting enough polyphenols can shorten a lifespan by making a person more likely to develop one of the chronic diseases mentioned above. For example, a 2013 study found that people who consumed more than 650 milligrams of polyphenols per day had a 30% lower chance of dying in any given year compared with people who got less than 500 milligrams per day.

So instead of a numerical RDA, the quasi-governmental Food and Nutrition Board of the Institute of Medicine recommends five fruits and/or vegetables a day, which theoretically would give you a significant amount of polyphenols. And if you “eat the rainbow” pretty much every day — that is, consume foods of many different colors (and no, Skittles don’t count) — you’ll also therefore get a wide range of polyphenols.

What Foods Are Rich in Polyphenols?

What Influences Polyphenol Amounts?

Unfortunately, you can’t simply look up a food’s polyphenol content in an online database and know exactly how much you’ll get when you eat that food. And even if you could, there are various factors that can influence how much you actually absorb.

Polyphenol Bioavailability

On the whole, polyphenols tend to have low bioavailability, which means your body can absorb and use only a small percentage of what you swallow.

The exact conversion ratio is based on many factors, including the health and makeup of your gut microflora. Since your microbiome can change on a constant basis, depending on what you feed it, how much of the polyphenols in your food you can actually get into your cells may also vary widely from day to day.

Also, the different polyphenols differ greatly in how bioavailable they are. The most abundant dietary polyphenols typically have lower absorption rates than less common ones.

Food Handling Impact

How plant-based foods are processed, stored, and cooked also strongly influences their polyphenol content.

If you remove the peels and hulls of certain foods, you can lower their polyphenol content. On the other hand, macerating (such as in a blender or food processor) some foods can increase their polyphenol content.

When it comes to food storage, the cold storage of apples, pears, and onions appears to maintain high polyphenol levels. But when cut fruits turn brown, which tends to happen if they are exposed to air, they begin to lose polyphenols.

Many foods lose polyphenol levels with time. For example, in wheat flour, concentrations of polyphenols drop by about 70% after six months. But black tea actually increases its polyphenol content after some oxidation.

Some polyphenol levels also increase with cooking, while others decrease — it depends on the food, the particular polyphenolic compound, and the cooking method. For example, onions and tomatoes lose between 75% and 80% of their initial quercetin content after boiling for 15 min, and 65% after cooking in a microwave oven.

So Should You Take Polyphenol Supplements?

A limited amount of research has indicated that people may possibly see benefits from polyphenol supplements. For example, athletes who were experiencing physiological stress were given polyphenol supplements, and they experienced some benefits in performance and recovery.

But the evidence is a bit murky: Many researchers don’t use pure polyphenols or mixtures, but add in other antioxidants — so it’s hard to know how much of the benefit is coming from the polyphenols, the other active ingredients, or some synergistic interaction of multiple elements.

There’s also not a lot of safety data available about these supplements. And as polyphenol marketing gives these compounds their place in the sun, some manufacturers are taking advantage of their popularity to create mega-dose formulations that have never been tested for safety or efficacy.

Because research on the benefits of polyphenols typically uses amounts much higher than those commonly found in human diets, we just don’t know the levels at which they are safe and beneficial for human consumption.

Some supplements (including those containing polyphenols) could cause liver damage in high doses, and may also block the absorption of nonheme iron, which is an essential nutrient.

Perhaps the best argument against supplementation is that it’s probably completely unnecessary for most people, as polyphenols are abundantly available in a wide variety of fresh and healthful foods.

Plus, just like every other plant-based antioxidant and phytonutrient, polyphenols work better in harmony with other nutrients that naturally occur in food. And when you consume whole plant-based foods, you also get the benefit of fiber and other health-promoting micronutrients.

In general, most people are better off getting their nutrition from food rather than from supplements, and there’s no reason to think that polyphenols are an exception.

Polyphenol Recipes

From bitter to salty, from sweet to tart, polyphenols are in abundance in many of your favorite plant-based foods. These delicious and nourishing polyphenol recipes are a great way to experiment with and incorporate them into your daily meal routine.

1. Banana Tahini Coffee Smoothie

Coffee is a plentiful source of polyphenols as it contains chlorogenic acids, which fight free radicals and prevent oxidative stress damage, making it a potent antioxidant-rich ingredient. Not only does it give you a burst of energy — you get a powerful health boost, too! Together with creamy banana, nutty tahini, nutrient-rich cauliflower, and sweet spices, this Banana Tahini Coffee Smoothie is an easy-peasy and ultra-creamy way to enjoy polyphenols.

2. Apple Walnut Sage Dressing

Apples have an abundance of polyphenols, more specifically anthocyanins, flavanols (catechins), flavonols (quercetin, rutin), chlorogenic and caffeic acids, and dihydrochalcones, which can help to reduce inflammation, support your immune system, and even help with seasonal allergies! We don’t think you’ll need any more convincing, but this creamy Apple Walnut Sage Dressing is an inflammation-fighting, health-promoting, and deliciously sweet and savory sauce that is the perfect polyphenol-rich addition to your favorite summer or fall salad.

3. The Shine Brightly Salad

We love The Shine Brightly Salad for many reasons. And the addition of sweet and juicy blueberries is a major factor! Blueberries are loaded with anthocyanins, resveratrol, and flavonols (quercetin), which are all under the umbrella of polyphenols. You’ll also get a hefty dose of health-promoting spinach, red onion, sunflower seeds, and lemon juice. With so many colorful plant foods combined, you know you’ll be getting a wide variety of phytochemicals, antioxidants, and other polyphenols that will keep your body in tip-top shape — and shining brightly from the inside out!

Eat More Plants to Reap the Benefits of Polyphenols

From fending off cancer and heart disease to supporting healthy blood sugar levels and bone density, polyphenols are like real superheroes of our dietary choices, working tirelessly to safeguard our well-being. These compounds are readily available in a wide array of whole foods.

While some individuals may find benefit from polyphenol supplements, on the whole, the safety and efficacy of high-dose polyphenol supplements remain unclear. So it’s probably best to get your polyphenols from food. And let your plate be a canvas of color and flavor, celebrating the goodness that polyphenols have to offer.

The post Polyphenols: Nature’s Prescription for a Healthier You appeared first on Food Revolution Network.

The list would almost certainly include persistent droughts in many heavily populated parts of the globe, depleted soils, global hunger, nutritional deficiencies, overuse of pesticides, and climate chaos caused by the carbon footprint of burning fossil fuels.

The bad news is you probably don’t have actual magical powers that allow you to create such a food. (If you do, please apply for a job at Food Revolution Network!)

The good news is, that crop already exists. It’s called fonio (pronounced “fone-yo”), and it’s the oldest known cultivated grain in Africa.

While many Indigenous West Africans revere the grain and incorporate it not only into their diets but also into their healing and spiritual practices, its cultivation was discouraged by decades of agricultural and economic policy that sought to “modernize” the region and grow monocropped grains for food and export.

But fonio is making a comeback, growing in popularity around the world. And for good reason. It’s highly nutritious, exceptionally delicious, and environmentally resilient, making it an important crop for arid regions. Those include its home, West Africa, but also many other places around the world prone to prolonged heat and drought: southern Europe, the Middle East, North Africa, much of the US (including California, Texas, the Midwest, Sunbelt, and Southeast), Southeast Asia, and Australia, among others.

In this article, we’ll explore all things fonio. We’ll look at where and how it grows, its nutritional profile and health benefits, its environmental impacts, and why you might want to add fonio to your diet even if you don’t live in West Africa.

We’ll also cover its versatile culinary uses, and share some fonio-filled recipes.

What Is Fonio?

Fonio, aka Digitaria exilis (Latin for “slender fingers”), has been cultivated in parts of Africa for about 7,000 years. In the Dogon language of Mali, one of the names for the plant means “seed of the universe.” In a narrative strikingly similar to the Big Bang, Dogon mythology describes the Creator bringing the universe into existence by exploding a single fonio grain.

Fonio is a member of the millet family and is related to other grains important in African agriculture, including pearl millet and sorghum. Technically, fonio is a very tiny pseudocereal, like quinoa and buckwheat — which basically means it’s a seed that’s eaten like a grain.

You may have also heard of fonio by one of its other names. These include acha, fundi, findi, iburu, Asian millet, fonio millet, pearl millet, and hungry rice. (That last name is something of a smear, implying that fonio is a lesser food that’s eaten only when there’s not enough rice.)

Fonio is native to West Africa with roughly 70% of the world’s fonio grown in Guinea. Additional production occurs in Nigeria, Mali, Senegal, and several neighboring countries.

Fonio has played a critical role in food security in these countries, especially in rural areas. For reasons that we’ll soon discover, fonio is a reliable staple crop even when other food sources are scarce.

The plant is prized for its resilience, able not just to grow, but to positively thrive in poor soil conditions. As a significant bonus, fonio is also the speed champion of grains. It’s the world’s fastest maturing cereal, going from seed to harvest in as little as 60 days. And it’s drought tolerant. In fact, the less rain the plant receives, the faster it matures.

Types of Fonio

There are two main types of fonio:

• white fonio, called acha (the more common of the two, and quicker cooking)
• black fonio, called iburu (less common, and higher in fiber)

Both types of fonio have a similar taste that’s been described as rich and nutty — similar to couscous (but unlike couscous, fonio is a whole grain, and it’s gluten-free!).

Fonio Nutrition

On a nutrient-by-nutrient basis, fonio appears to be one of the most nutritious of all African cereals, as well as one of the tastiest. A cup of cooked fonio (which requires a quarter cup of dry grain) provides about 170 calories, largely from carbohydrates, and a small amount of protein.

It’s also a rich source of gut-healthy fiber, providing as much as five times as much fiber as a serving of white rice. (I don’t know about you, but I sometimes opt for white rice over brown rice when I’m in a hurry since it cooks much more quickly. Well… fonio cooks even faster yet! So it is a winner by many measures of comparison.)

What about the essential amino acids that make up protein? The acha variety of fonio is particularly rich in sulfur-containing amino acids, like methionine, which is an amino acid that is typically low in legumes. However, similar to whole grains, acha is low in lysine (where legumes excel!). While we love fonio, we don’t recommend that you only eat fonio all day. Variety, including beans and other legumes, is important to ensure you’re receiving a variety of nutrients, including plenty of all the different essential amino acids.

Fonio is also a solid source of several minerals, including calcium, iron, zinc, magnesium, and copper. Since fonio is gluten-free, it can substitute for gluten-containing grains such as wheat, barley, and rye for people with Celiac disease and gluten sensitivity.

Fonio Health Benefits

Just as fonio has been systematically neglected and marginalized by industrialized agriculture, it’s also largely ignored by nutrition researchers. While its powerful nutrient profile is well-documented by modern science, the same is not true of its potential for supporting human health.

To give you a sense of the gap, when I did a search for “fonio nutrition” in the database of the US National Institutes of Health National Library of Medicine, I got 17 hits (only one of which even looked at the relationship between fonio and human health). By comparison, “corn nutrition” generated over 12,000 articles, and “sorghum nutrition” almost 1,200.

So in order to make useful statements about how fonio might help you prevent and heal from disease, we have to consider both its nutritional properties and Indigenous healing practices.

In West Africa, fonio is considered to have medicinal properties for several health conditions. In Senegal, fonio has been traditionally used to alleviate conditions such as meteorism (or bloating and abdominal distension caused by an accumulation of gas in the digestive system), constipation, and as a diuretic. Also, the Senegalese use fonio to treat blood clots, diarrhea, loss of appetite, dysentery, stomachache, chicken pox, and asthma.

In Burkina Faso, fonio is known for its slimming properties. Roasted, it’s used for wound healing. And fonio dough is given for relief of symptoms in people with type 2 diabetes.

Based on its nutritional profile and similarity to other pseudocereals, it’s probable that fonio may reduce the risk of developing both type 2 diabetes and some cancers. And with a low glycemic index (in the low 40s, to be imprecise) and favorable amounts of both resistant and nonresistant starch, fonio may help improve blood glucose management in diabetic and prediabetic patients.

Challenges Facing Fonio

We’ve seen that, in many respects, fonio is a near-perfect crop to address hunger on a planet that’s growing increasingly hot and dry. But now it’s time to address the one drawback to fonio: It takes a huge amount of hard human labor to produce.

Labor

In West Africa, where fonio is still a staple food for millions of people, all stages of its growth cycle are very labor-intensive.

Men harvest the grain by uprooting the plant or cutting off the grain head with a homemade knife or sickle. Threshing the grain — separating the edible from inedible parts of the plant — is just as labor-intensive. It’s done by either beating or trampling over the dry straw.

In West African countries, women perform the lion’s share of the work. Women typically do the weeding, collecting seed heads, dehusking the grain, cleaning, drying, and processing as well as selling the fonio. On average, a woman must pound fonio for an hour to dehusk just two pounds of the grain.

Although this unfairly puts a large burden on women to process the fonio and get it ready for market, from a climate perspective, the hard work does pay off. Its impact in terms of greenhouse gas emissions, as well as soil and water contamination, is minimal to nonexistent. There’s also no need for fuel to run giant harvesters and other agricultural machines, or to power running water for irrigation.

And in a region with chronically high rates of unemployment, some would argue that providing more jobs for people (as opposed to having the work done by machines produced overseas) makes good economic sense, too. Plus, there’s the fact that farmers don’t have to spend money on fertilizers or pesticides since fonio thrives in poor soil and has few natural enemies.

But in terms of growing enough fonio to feed the world, the fact that the crop hasn’t, at least so far, been able to benefit from economies of scale has been a very real stumbling block.

In the 1990s, a Senegalese mechanical engineer named Sanoussi Diakite invented a fonio husking machine that could process eleven pounds of grain in just eight minutes. However, there are very few machines in use, even today, because the $3,000 price tag renders them too expensive for the vast majority of West African farmers.

Low Demand and Rural Depopulation

Capitalizing on fonio’s status as a highly nutritious and easy-to-grow whole grain is a serious challenge facing West African farmers. In addition to the difficulties of production and postharvest processing, there are two other stumbling blocks: low market demand and rural depopulation.

Because demand from the wealthier nations is low (at least before this article was published!), farmers fear not receiving a return on their investments of money and effort. It’s more secure to grow maize, which has a predictable market, or some of the higher-margin cash crops like coffee, bananas, cashews, or cacao, which can be exported to wealthier countries.

Another obstacle is a lack of younger farmers willing to do the work of fonio farming. Many move away from rural areas to seek employment in the cities, sparking a depopulation crisis that continues to spiral as more and more people view farm life as an economic dead end.

Garnering Interest in Fonio

Some people are trying to encourage increased fonio production by creating demand for it in the US and Europe. Making fonio more fashionable, somewhat akin to what’s happened to quinoa, can mean higher profits and more stable income for farmers.

For example, Senegalese chef Pierre Thiam has been instrumental in bringing fonio to US markets. He cofounded Yolélé Foods in order to, quoting from their website, “create economic opportunity for smallholder farming communities; to support their biodiverse, regenerative, and climate-resilient farming systems.”

Yolélé Foods is also building processing facilities and collaborating with governments, intergovernmental agencies, and NGOs to train and equip smallholders for increased productivity through conservation farming.

If you’re feeling adventurous and want to try fonio for yourself, check out some of Yolélé’s fonio products online. If they’re out of stock (as seems to happen from time to time), Aduna makes an organic variety, linked here. The cost tends to be a bit higher than rice or quinoa but is lower than wild rice.

How to Cook Fonio

If you do decide to try fonio (and create more demand for it), you’re in luck. Not only is it super delicious (at least in my opinion), but it cooks super fast (just a few minutes!). This speedy quality also makes it a great option when you want to eat a whole grain but don’t have a long time to wait for one to cook fully.

One cup of fonio cooks in two cups of water and yields four cups of grain!

You can use fonio in any recipe that calls for other types of grains. Examples include grain bowls, porridge, side dishes (like couscous or pilaf), stuffed vegetable recipes, and so on.

Fonio flour has been used to make biscuits, bread, and dumplings. Some researchers have experimented with making sourdough bread using fonio. It’s also possible to make delicious cakes, cookies, and other snack foods and desserts from fonio. And you can use whole meal fonio flour to create gluten-free biscuits and other baked goods.

Fonio Recipes

This ancient West African grain deserves to be making some serious culinary waves because it offers a delightful canvas for kitchen creativity. From savory to slightly sweet, get to know this delightful ancient grain that can add wonderful texture and substantial nutritional value to your meals.

1. Savory Turmeric Fonio Porridge

Savory Turmeric Fonio Porridge feels like a warm and comforting hug for your belly.

The Bottom Line on Fonio

Fonio is a nutritious and versatile whole grain that has a low environmental impact. It also tastes delicious, cooks quickly, and provides many nutrients that are crucial to human health. Plus, it’s gluten-free and so is suitable for those with Celiac disease or gluten sensitivity.

Unfortunately, farmers face many challenges growing fonio because demand is unpredictable, and it’s labor-intensive to harvest and thresh. While some technology is now available to lessen that burden, until demand grows, few farmers will be able to afford to use these machines to increase production.

Increasing awareness of and demand for fonio in industrialized countries can be a win-win. Not only does the crop have the potential to improve the nutritional status of those populations, but increased demand may translate into funding to make harvesting and processing more efficient. If done in an environmentally low-impact way, this could pave the way for greater economic opportunities for farmers in West Africa.

If being a part of that solution sounds good to you, check out the recipes included above and consider making fonio a part of your life.

The post What Is Fonio? Get to Know This Ancient Supergrain from Africa appeared first on Food Revolution Network.

Well, that’s the experience I just had researching this article about figs. I thought I knew a lot about this yummy fruit until I started digging into the topic. Spoiler alert: They’re not even fruits! And when I discovered how they get pollinated — that’s a drama worthy of a Game of Thrones episode!

But aside from their storied pollination method, figs have a lot to offer. In addition to being a delicious food, figs have also traditionally been used for healing and for some very practical purposes. For countless generations, people around the world have made poultices from fresh or dried figs, fig leaves, and fig wines. Fig stems and leaves contain latex. And, of course, fig leaves have served as, well, strategically placed garments since the Garden of Eden (at least according to some Renaissance painters).

You can also find mention of figs in both the Bible and the Quran. Biblical writers often use figs as metaphors for the physical and spiritual health of the people, with phrases like “everyone under their own vine and under their own fig tree” depicting a time of peace and prosperity. The Quran quotes the prophet Muhammad as telling his followers to eat the fig “as it cures various diseases.”

In this article, we’re going to focus on the culinary uses of figs. We’ll explore what figs are, how they taste (and how they differ from dates), the nutritional value of fresh vs dried, and their health benefits and downsides.

We’ll also look at how they get pollinated (so dramatic!), and if that process might render figs unfit for a vegan diet.

What Are Figs?

Fig trees (or Ficus carica) are native to the Mediterranean region and were one of the first plants to be cultivated.

Figs are members of the mulberry family, which, contrary to the nursery rhyme, is mostly populated by trees, not bushes to “go ‘round and ‘round.” (Other family members include the banyan, breadfruit, jackfruit, and Osage orange.)

A fig fruit (which, again, is not really a fruit) is known as a syconium. According to the Ecological Society of America, “a fig is not actually a fruit; it is an inflorescence — a cluster of many flowers and seeds contained inside a bulbous stem.” And as we’ll see, it’s that structure that makes its pollination so darn interesting.

Because the fig flower is arranged so unusually, the seeds — which are actually the ovaries of the fig — can’t be pollinated by ordinary flying insects like bees, moths, and butterflies. Instead, it requires a pollinator with the skills of a safecracker who can operate in dark, confined quarters (more on that later).

Types of Figs

There are more than 750 different varieties of fig. Some of the types you’re likely to encounter include Adriatic, Black Mission, Turkish/Brown Turkey, Calimyrna, Kadota, Celeste, and Tiger. Different types have different flavor profiles, and feature in a variety of dishes, from sweet desserts to more savory fare.

The most common dried figs in the US are Black Mission and Golden, both of which are grown in California.

Figs are light green as they grow. They may remain green or change color as they ripen, ranging from yellow to brown to dark purple, depending on the cultivar.

The Differences Between Figs and Dates

Figs and dates are two very different foods that people sometimes get confused with one another, kind of like the actors who play Harry Potter and Frodo. Here are some key differences. Frodo didn’t go to Hogwarts — oops, I mean, here are some key differences between figs and dates.

While figs originated in the Mediterranean region, dates are native to several geographical locations, including North America. Figs grow on trees, while dates are the fruits of palm trees, which are technically grasses and not trees (this is such a genus-bending article!).

Furthermore, figs grow on fig tree branches, while dates grow in clusters on offshoots from the main trunk of the palm tree. Dates contain a single pit, while figs have many small edible seeds.

When it comes to eating the fruits, they’re also quite different. Figs have three times the amount of water as dates, which also makes them much lower in calories (about four times lower, if you’re counting). So dates are a much more concentrated source of carbohydrates, mostly in the form of simple sugars. Dates are also richer sources of some minerals, such as calcium and potassium.

Nutrients in Figs

The good news is figs deliver a lot of essential nutrients. The predominant macronutrient (the one that provides calories) is carbohydrates, but they’re also rich in some vitamins and organic acids. As whole plant foods, they also provide important dietary fiber.

According to the US National Nutrient Database, two medium raw figs contain roughly 3 grams of fiber. Doing the math, this means that if you ate just 8 figs a day and nothing else, you’d still get about half as much fiber as the average US resident consumes in a day. (To be clear, I am NOT recommending the “8 Fig a Day Diet,” although someone could probably write a best-selling diet book with that title.)

However, some researchers have measured much greater amounts of fiber in different fig cultivars. According to the American Botanical Council, two fresh or 4–5 dried figs provide a whopping 12 grams of fiber.

So we have credible authorities telling us that two figs provide 3 grams of fiber, while others say the correct figure is 12 grams of fiber. It reminds me of the old saying, “A person with one watch knows what time it is. A person with two watches… is never quite sure.” So for now, let’s just say that figs are high (potentially very high!) in fiber, and leave it to the good folks at the US National Nutrient Database and the American Botanical Council to duke it out on the details.

Figs are a good source of many bioactive phytonutrients, too, including flavonoids, phenolic acids, carotenoids, and tocopherols.

(Here’s a fun article all about flavonoids, which starts with a weird story about a bunch of soldiers trying to cross a bridge.)

They’re also solid sources of potassium, calcium, sodium, magnesium, and phosphorus. What’s more, figs provide essential trace elements, including iron, manganese, zinc, and copper.

You’ll get the most nutrients if you don’t peel your figs; the highest concentrations of phytonutrients are in their skin. And darker fig varieties contain more polyphenols and antioxidant power than lighter ones.

Figs also lose some phytonutrients when dried. Studies show a loss of 29% to as much as 86% of the polyphenol content when figs are dried.

Health Benefits of Figs

In the Middle East and Mediterranean regions, figs have long been revered for their contributions to human health and longevity. The fruit, leaves, latex, bark, and roots of fig trees have been used to treat gastrointestinal, respiratory, inflammatory, and cardiovascular disorders, as well as ulcerative diseases and cancers. The various parts of the fig tree possess a wide variety of properties; they can help you poop, relax muscle spasms, fight viruses and bacteria, bring down high blood sugar, and even help your body expel parasites.

And modern scientific research has only added to our understanding of the power of figs to promote health.

Figs and Gut Health

When patients with irritable bowel syndrome add figs to their diet, they often experience decreased symptom occurrence and severity. A 2019 study gave IBS patients 90 grams of dried figs per day for four months. Compared to controls who didn’t get anything, the fig-enhanced group had reduced frequency of pain, less intestinal distention, more frequent pooping, and softer stools. Unsurprisingly, they also reported “a significant increase in quality of life.”

In a 2018 animal study, rats with induced ulcerative colitis were fed a liquid extract containing figs. The treatment had a natural laxative effect but did not lead to diarrhea, and it improved their gastrointestinal functioning. (Our view on the use of animals in medical research is here.)

Figs and Diabetes

Figs (and fig leaves) can also be deployed to treat diabetes. A 1998 study found that people with type 1 diabetes who drank tea made from fig leaves were able to lower their blood sugar immediately following meals. And a 2019 study showed that a fig leaf decoction was able to lower blood sugar in people with type 2 diabetes by about half as much as the drug metformin (after two months of treatment).

It’s not just the leaves, though — fig fruits contain a compound called abscisic acid (which should definitely be included in spelling bees) that has been shown to reduce blood sugar levels after meals.

Figs and Cognitive Decline

Studies with experimental animals have shown that figs may help us stay sharp and avoid or delay cognitive decline. One animal study compared the effects of a diet that included figs to a fig-free diet in mice that were genetically engineered to develop Alzheimer’s disease. The mice who ate figs did better on memory tests, displayed fewer anxiety behaviors, learned new things more quickly and fully, and had better motor coordination. Furthermore, the fig-eating mice had lower levels of the toxic amyloid beta proteins that are associated with the development of Alzheimer’s disease.

Are Figs Vegan?

This may seem like an odd question, but remember that Game of Thrones reference from earlier? It turns out, fig tree pollination is a bit controversial.

You see, there are two types of fig trees: wild and cultivated. And wild-growing fig trees require pollination to bear fruit. The critters that have volunteered for the job are fig wasps, a term that describes any of several hundred different, mosquito-like tiny creatures from the Agaonidae family. Each species of fig wasp pollinates only one variety of fig.

Basically, here’s how it works.

A female wasp, loaded with pollen, flies to an unripe fig and burrows into its center to deposit her eggs. While she’s doing this, two things happen. One, she spreads her pollen onto the female flowers. And two, the effort of fighting her way through the flower strips her of her wings.

Now the fig goes to work, building structures called galls over the wasp eggs and producing seeds in the flowers that don’t contain the eggs. Meanwhile, the mama wasp dies, whereupon her exoskeleton is dissolved by figgy enzymes. (Cue the emotional orchestral music.)

The heroic male wasps hatch first, and travel around the syconium fertilizing their sisters who are still pupating in their galls. (This is definitely HBO-worthy stuff!) Then they dig holes through which the fertilized females can escape with their wings intact. Once the females hatch, they fly off to repeat the process, leaving the males to die in the maturing fig.

Pretty intense family drama, huh?

As a result, some vegans do not eat figs because they don’t want to consume dead wasps, and also because animals died as part of the process that produced them. However, there’s good news if you want to adhere to a vegan diet and still enjoy delicious figginess.

First, the wasps are completely dissolved by the plant enzymes, so you are not likely to encounter a dead insect in your fig. And second, almost all figs produced and sold in the US are of the cultivated variety and are self-pollinating. This means they don’t need the sacrificial services of the fig wasps, and are considered vegan-friendly.

Fig Downsides

Aside from the fig wasp controversy, there are some other things about figs to consider. For one, some people may have to avoid them because of allergic reactions, including oral allergy syndrome. The latex in the plant may also be a source of irritation and allergy, especially if you’re harvesting figs.

Also dried (but not fresh) figs are high in compounds called salicylates, which may cause swelling, itching, hives, worsened asthma, and food intolerance symptoms in people who are sensitive to them.

The other thing about figs is that it takes a lot of water to grow them. Although they’re not as needy as some other crops like citrus, almonds, alfalfa, and pasture grasses, in places straining under multiyear droughts, such as California and Spain, this can be a problem.

On the other hand, fig trees, like almond trees, are drought tolerant, so they can be a good solution in some cases. While they may not bear fruit during times of drought, they can survive until the rains return. There are several strategies growers can implement, including mulching, thinning fruit to help the remaining fruit develop fully, and protecting trees with shade cloth during the hottest parts of the day.

One other challenge with growing figs, and I say this from personal experience, is that for some reason gophers love their roots. So if you aim to grow a fig tree, it may be wise to place a wire gopher barrier in the planting hole to protect the root ball from those sharp little teeth.

Overall, growing figs appear to be a net positive for the environment. Offsetting their water needs and their moderate carbon footprint, they don’t require heavy use of pesticides. Plus, fig trees sequester carbon in their biomass, keeping it out of the air and not contributing to the climate crisis.

We Dig Figs!

As you’ve probably gathered by now, figs are pretty unique! Their biology is fascinating, and the saga of their pollination is dramatic, to say the least. They also offer a wide range of essential nutrients and health benefits. From their versatile culinary uses to their historical uses as healing agents, figs have proven themselves valuable partners to the humans who have loved, cultivated, and revered them for millennia.

Since then, the search for a fountain of youth has been a recurring obsession of kings and explorers, pilgrims and pirates. As far as I know, none of them ever found it (or if they did, they aren’t sharing any details). No spring, river, pond, lake, or sea has magically rejuvenated the bathers who submerged themselves in its water to the point where creaky elders limp in and dewy-eyed adolescents leap out.

If you’re searching for clues to living a long and healthy life, you probably need to look elsewhere. And a huge factor in the rate of aging turns out to be a class of compounds found in many of our most common (and sadly, most beloved) foods. If you want to slow down your biological clock, limiting your consumption of these foods appears to be a much more reliable and effective strategy than dunking yourself in a mangrove swamp in Bimini or a waterfall pool at the foot of a South Indian mountain.

The compounds are known to biochemists as advanced glycation end products, which might be hard to remember except for their most excellent acronym: AGEs. As in, AGEs that accumulate in your tissues — make you age faster.

Aging isn’t just a vanity issue that sells stock image licenses to fashion magazines and anti-wrinkle creams to their readers. It’s a big deal for your overall health because, statistically speaking, the single biggest risk factor for disease and death isn’t your genes, or your diet, or how much you exercise, or whether you live downwind of a Superfund site, or whether you drink enough water or put on sunscreen, or any lifestyle or environmental factor; it’s your age.

Which means that because AGEs can contribute to the development of various age-related diseases and conditions, they can shorten your lifespan.

The good news is, you have a lot of control over the amount of AGEs you consume, which in turn largely determines the concentrations of these compounds that accumulate in your body and how much harm they get to perpetrate.

In this article, we’ll dive into the world of AGEs and their impact on your health. We’ll see how your food choices — as well as various cooking methods — can affect the formation of AGEs. And we’ll discover some simple and delicious ways to minimize AGEs in your diet — so you can increase your odds of a longer, healthier, and happier future.

What Are AGEs?

Advanced glycation end products are harmful compounds that form through a natural process called glycation. It takes place inside your body when the sugars in your bloodstream react with proteins, lipids (fats), and nucleic acids from the food that you eat.

You can also introduce AGEs into your body fully formed, as it were. They form exogenously (that is, outside the body) when foods are browned and their outer layer becomes crispy and crunchy. This chemical reaction is known as the Maillard reaction, or nonenzymatic browning. The Maillard reaction gives foods a texture, taste, color, and aroma that most people find very pleasing.

You can also introduce AGEs into your body through drinking alcohol and smoking.

As you age, AGEs can start to accumulate in your tissues and organs. The more your blood sugar levels fluctuate, the more AGEs form, and the more the effects of glycation intensify and accelerate the aging process.

AGEs can also cross-link with various proteins in your body, leading to the formation of abnormal structures and interfering with the functioning of important molecules. This further contributes to the aging process.

Why Are AGEs Bad for You?

Advanced glycation end products have been shown to be toxic, immunogenic (triggering an immune response, typically unwanted and over-the-top), and capable of triggering cellular injury. Another remarkably on-point acronym, RAGE, stands for Receptor for Advanced Glycation End Products. It is a receptor protein for AGEs that plays a role in the inflammatory response and has been implicated in various age-related diseases and conditions, including skin damage, respiratory disorders, neurodegenerative diseases like Parkinson’s and Alzheimer’s, cancer, type 2 diabetes, and cardiovascular disease.

Skin Health

AGEs contribute to skin aging, including the formation of wrinkles and brown spots. They affect how proteins work in the dermis (the middle layer of your skin), leading to lots of problems: decreased elasticity, delayed recovery from wounds, accelerated skin aging, and inflammation that can contribute to skin conditions like dermatitis and psoriasis.

Collagen (a type of protein found in our connective tissue, cartilage, bone, and tendons) is one of the structures most easily attacked by AGEs. Over time, AGEs can accumulate on collagen, causing the skin to turn yellow.

Neurodegenerative Diseases

Autopsies of people who died from or with Alzheimer’s disease have shown accumulations of AGEs have been found in their brain plaques, as well as in their blood serum and cerebrospinal fluid. AGEs can also hasten the ravages of Parkinson’s disease by contributing to neuronal cells’ self-destruction as well as the formation of Lewy bodies (structures associated with abnormal deposits of a particular protein in the brain).

Respiratory Disorders

The more AGEs a person consumes, and the more frequently they eat meat, the more likely they are to experience breathing problems. This includes symptoms of asthma in children, such as wheezing. Kids who consume the most AGEs typically need more asthma meds, have their sleep interrupted by wheezing episodes, and are most limited in their ability to exercise without shortness of breath.

When COVID-19 hit, many of the initial deaths were linked to an immune system overreaction known as a cytokine storm. AGE consumption appears to be linked to worsening outcomes in COVID patients due to more extensive lung damage. AGEs also can lead to severe pneumonitis (inflammation of the lung tissue) by impairing the immune response, triggering inflammation, changing the structure of lung tissue in a way that decreases lung function, and enabling bacteria to adhere more easily to the lungs.

Type 2 Diabetes

The AGEs that are created by cooking certain foods in certain ways (known as exogenous AGEs, to differentiate them from the endogenous AGEs that are synthesized inside our bodies) can be extremely harmful to people with type 2 diabetes. In addition to adding to the inflammation that can trigger the development of the disease, AGEs also contribute to diabetic retinopathy and other related issues that can damage eyesight.

Some of the vascular dysfunction associated with diabetes can be prevented by blocking the RAGE receptors. And proactively consuming a diet low in AGEs can increase insulin sensitivity, which can reduce the risk of developing type 2 diabetes in the first place.

Cancer

With cancer, AGEs can act like gasoline thrown on a fire, increasing carcinogenic processes in a wide range of cancers and promoting their malignant behaviors. A 2015 study of male members of the US-based AARP found that the more AGEs they consumed, the greater their risk of developing pancreatic cancer. And a 2022 study of over 14,000 Japanese men found that high AGE intake was significantly associated with an increased risk of liver cancer.

AGE-Forming Foods

I hope by now you’re motivated to find out where these AGEs are hiding, so you can consume as little of them as possible. So here are the five main categories of AGE-forming foods.

Meat

In the standard industrialized diet, meat is typically the largest contributor to AGE formation. They’re created when the proteins in meat get a little too friendly with sugars, particularly glucose and fructose, that can be added during processing (some examples are many forms of bacon, hot dogs, and corned beef) or via marinades.

When meat is cooked at high temperatures, especially over an open flame or on a grill, it can produce harmful compounds that contribute to AGE formation. Some of the worst offenders are heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which are classified as potential and known carcinogens, respectively.

Regardless of the cooking method, any blackened or charred meat will contain these compounds. The levels depend on the type of meat (beef is worst), cooking conditions, and final internal temperature.

If you’re wondering why humans tend to love the color, smell, texture, and taste of something that’s so bad for us, it’s probably because the Maillard reaction is a good indicator that the meat has been cooked enough to kill the pathogens that could kill you. From an evolutionary perspective, the AGEs that keep us from reaching old age are far preferable to the germs that could end your life in the next few hours or days.

Fried Foods

Frying and other high-heat cooking methods also increase the AGEs in foods. A big culprit here is the repeated heating and use of cooking oil in commercial settings. That oil accumulates large amounts of AGEs, which get transferred to those fries or mozzarella sticks when they’re submerged in their fryer basket.

The longer the food is exposed to high-temperature frying, the more opportunity there is for the Maillard reaction and AGE formation to occur. Even changing the cooking oil daily leaves room for lots of AGEs. Swapping out large containers of hot oil is a dangerous and not very fun job, so some restaurants or commercial kitchens schedule the task only every few days. (I asked a friend’s son who once worked in a local restaurant how often they changed their cooking oil, and he responded, puzzled, “I have no idea if they ever do.” Sometimes I’d rather not know certain things.)

Cheese

The highest concentrations of AGEs are found in aged and hard cheeses in particular, probably because they’re pasteurized and/or they spend a lot of time aging or curing at room temperature — conditions that make up a veritable AGE factory. But all dairy cheeses are potential sources of AGEs, perhaps because dairy contains large amounts of fat along with natural lactose sugar.

Processed and Packaged Foods

Processed and packaged foods are often high in AGEs. Many of them contain added sugars, and undergo high-temperature processing as they’re baked or fried. They’re high in AGEs via that good old Maillard reaction, which is responsible for the browning and flavor development in cooked foods, and which can also extend shelf life.

Sugary Foods

Since AGEs form via glycation (essentially, sugarcoating proteins and fats), foods high in added sugars, such as candies, pastries, and sugary beverages, can provide fodder for the glycation process and contribute to the formation of AGEs.

There’s data that suggests that the glycation process following high sugar intake may be a key player in the development of metabolic disturbances.

Foods and beverages with a high fructose-to-glucose ratio may promote AGE formation. These can include anything with high-fructose corn syrup, agave nectar, honey, and filtered fruit juices. A glaring exception to this rule is fruit, which is actually protective against AGE-related disease thanks to its high fiber content.

Especially worrisome are commercial soft drinks sweetened with high-fructose corn syrup, which are often high in an intermediate product of the Maillard reaction called methylglyoxal.

Why Eating a Whole Food Plant-Based Diet Is the Best Way to Avoid AGEs

You can’t avoid AGEs entirely — pretty much every food contains some. But whole plant-based foods, including fruits, vegetables, whole grains, legumes, nuts, seeds, and herbs and spices, naturally have lower levels of AGEs than animal-derived foods. And some cooking methods commonly used on plant foods — steaming, boiling, and baking — produce fewer AGEs than the higher-temperature methods like frying, grilling, and broiling that are commonly used for foods of animal origin.

It’s definitely possible to get exposed to significant quantities of AGEs on a plant-based diet if you routinely fry starchy foods like potatoes (I’m looking at you, potato chips and french fries!). These foods also produce acrylamide, another compound that may be problematic for some people when consumed in large quantities.

But even when fried or broiled until brown and crispy, most whole plant-based foods offer compounds that can mitigate the damage caused by AGEs. Many are rich in antioxidants, such as vitamins C and E, the provitamin beta-carotene that your body converts to vitamin A as needed, and various phytochemicals that help neutralize the free radicals that can contribute to AGE formation and oxidative stress in the body.

Also, the soluble fiber available from plants helps regulate blood sugar levels and can reduce the glycation process by slowing down the absorption of sugars in the bloodstream.

5 Foods (and 1 Beverage) That Prevent Glycation

You can go a long way toward reducing AGEs and RAGE in your body by avoiding or limiting highly processed foods and those of animal origin, and by using lower-temperature cooking methods that don’t produce crispy, crusty browning on the outside.

In addition to those strategies, you can also consume some specific foods that contain compounds that inhibit the glycation process, so that the AGEs you do inevitably consume have less risk of causing aging and accompanying health problems.

Berries

The antioxidants in berries help reduce the conditions that lead to glycation by scavenging and neutralizing free radicals. Polyphenols found in berries, especially anthocyanins and quercetin, may directly inhibit the formation of AGEs. And extracts made from the skins of red grapes (which are, botanically speaking, berries) were able to inhibit the creation of AGEs in a test tube containing fructose-glycated proteins.

Berries also deliver anti-inflammatory and blood sugar-balancing effects.

For more on berries and some “berry” great recipes, see our article here.

Spices

Many spices, some commonly used in modern kitchens and some still awaiting their turn as superfood du jour, have been shown to prevent AGE formation through their powerful antioxidant activity. Examples include star anise, cinnamon, allspice, and cloves, which are staples in many traditional cuisines around the world. And good old black pepper also performed well at this task.

Other powerful anti-AGE spices include garlic and turmeric which contains the powerful antioxidant curcumin.

For more on herbs and spices, see our article here.

Nuts

Nuts, led by walnuts and pistachios, are great at inhibiting the glycation process in early and intermediate stages, before they even have a chance to reach the end stage indicated by “AGEs.” They are also powerful anti-inflammatories, helping to prevent damage related to any glycation that still occurs. Additionally, nuts have high antioxidant capacity (thanks to their concentrations of vitamin E) and are rich in phenolics and flavonoids that fight free radicals.

For more on nuts, see our article here.

Cruciferous Vegetables

Cruciferous vegetables contain the powerhouse antioxidant and anti-inflammatory sulforaphane, which is famous not just for giving cabbage and broccoli their distinctive odors, but also for being one of the most effective cancer fighters ever identified.

One of the ways sulforaphane delivers its massive health benefits is by inhibiting AGE-induced damage. In this way, it may prevent cardiovascular and diabetes-related complications. Broccoli sprouts, in particular, may play a protective role against vascular injury by inhibiting the AGEs’ (and their receptors’) axes and exhibiting anti-inflammatory actions.

For more information about sulforaphane and how to get it into your diet even if you aren’t a cabbage fan, check out our comprehensive article here.

Citrus

Perhaps the OG antioxidant, and certainly the one with the most publicity, vitamin C lives up to its reputation by helping to inhibit glycation processes. When researchers marinated lean beef in lemon juice for an hour before cooking, it ended up with half the AGEs as the same cut of beef marinated in vinegar.

It’s not just the vitamin C in citrus foods that deserves the credit. Flavonoids such as hesperidin, naringin, and quercetin have anti-inflammatory effects and help reduce the conditions that promote glycation. Hesperidin in particular is being studied for its potential to treat glycation-induced neurotoxicity involved in Alzheimer’s disease.

Citrus fruits also support healthy endothelial function. The endothelium, a layer of cells that lines your blood vessels, can contribute to the development of AGEs when it isn’t working properly, so the support of compounds in citrus fruits can go a long way in keeping glycation in check.

For more on the health benefits of oranges, see our article here.

Green Tea

There’s a compound found in green tea called epigallocatechin 3-gallate, which goes by its fun acronym EGCG, which sounds like the name of a trendy dance club from the 1980s (there may be an alternate universe in the multiverse in which I know very little about nutrition and a great deal about house music). EGCG helps protect proteins and other molecules from glycation by neutralizing free radicals before they have the chance to party and form AGEs. In this way, green tea consumption may help prevent neurodegenerative disease.

Through the same pathways, EGCG may also reduce plasma glucose and alleviate complications of diabetes.

AGEs can Age You!

AGEs contribute to a number of health conditions, from skin aging and respiratory disorders to neurodegenerative diseases and cancer. Although AGEs occur naturally as you age, and are found in food and produced in your body, you do have a lot of control over how much you’re exposed to them through diet. By avoiding AGE-forming foods such as animal products and processed foods, you can minimize your intake and protect your body from further harm. You can also reduce your exposure by embracing healthier cooking methods, reducing or eliminating added sugars, and choosing antioxidant-rich plant foods like berries, spices, nuts, cruciferous vegetables, citrus fruits, and green tea.

Humans have been cultivating grapes for a long time — possibly as long as we’ve been living in civilizations. Babylonian ruler Hammurabi, famous for publishing the world’s first written code of laws, used his power to regulate the wine trade in the 18th century BCE.

The ancient Greeks and Romans worshiped the God of Wine (named Dionysus and Bacchus, respectively) with festivals, rituals, and, yes, drunken parties, too. When the Vikings first landed in North America, they found it so covered in wild grapes that they named it “Vinland.”

And the grape’s popularity hasn’t diminished with time. By edible weight, grapes are the world’s number one fruit crop, with about 74 million tons produced each year.

Grapes are grown for three purposes: eating fresh (as table grapes), eating dried (as raisins), and drinking (as wine and grape juice). But roughly half of all grapes grown around the world end up in wine bottles.

Given that grapes are high in naturally occurring sugars, and that they’re frequently fermented in alcoholic beverages, are grapes actually healthy? What about when that sweetness is concentrated in raisins? And how do we make sense of all the conflicting information about whether compounds in wine help us live longer, or cause disease?

What Are Grapes?

Grapes are small, round fruits — technically berries — that grow in clusters on deciduous vines of the flowering plant genus Vitis.

There are a number of grape colors, ranging from yellow to green to red to crimson to purple to black (with even some dark blue and orange varieties thrown in for good measure). The darker grapes get their hue from differing kinds and concentrations of anthocyanins, a type of flavonoid that’s very interesting to health and antiaging researchers because of its unique antioxidant effects.

The taste of grapes can vary from very sweet to slightly tart, depending on the variety. They’re commonly enjoyed both fresh and as a key ingredient in various culinary preparations such as juices, jams, jellies, wines, and raisins.

Types of Grapes

While you could theoretically dehydrate any old grape into a raisin, cook it into jelly, or press and ferment it into wine, there are different varieties that are considered optimal for each of these culinary purposes.

Vitis vinifera is the dominant grape species for winemaking (in Latin, its name means “grapevine carrying wine”). You may be familiar with some of its more famous varieties, including Sauvignon Blanc, Syrah, Riesling, and Muscat Blanc. Vinifera grapes have a high sugar content and come in a wide range of berry sizes.

Table grape varieties include Thompson, Flame, Crimson seedless, Concord, Muscat, Niagra, and Red Globes. Most are bred to be seedless.

I know that seedless fruit can seem weird and unnatural (how do they have children!), but they are created through natural mutation and cultivated via cuttings. That’s a completely different process from genetic engineering. Interestingly, the descendants of this process are clones of their parents (meaning that they are genetically identical).

Raisin grapes are also typically high-sugar cultivars that are seedless. Some of the most popular raisin grapes include common table grapes like Muscat, Sultana, Thompson seedless, and Fiesta.

Grape Nutrition

As proud members of the fruit and berry families, grapes are nutritional powerhouses. According to the USDA, a serving of grapes is one cup or about 32 grapes. (I would have guessed fewer. But this is one experiment that is totally safe to do at home, so the next time I buy a bunch of grapes, I’m going to count one cup’s worth myself.)

In addition to a hefty dose of hydration, a cup of grapes will provide, on average:

• 104 calories
• 27.3 grams of carbohydrates
• 23.4 grams of sugar
• 1.1 grams of protein
• 1.4 grams of fiber
• 18% of the daily value (DV) for vitamin K
• 6% DV for potassium
• 21% DV for copper
• 9% DV for thiamin
• 8% DV for riboflavin
• 8% DV for vitamin B6

Raisins also contain a decent amount of potassium, copper, and fiber. However, because the water content of the grapes has been removed, you’re mostly left with a concentrated sugar source. One small 1.5-oz box of raisins can contain a whopping 28g of sugar! However, as you’ll see below in the section on health benefits, raisins do share many of the health benefits of raw grapes. But make sure to brush your teeth after, as dried fruit tends to stick to the teeth.

Antioxidants in Grapes

When it comes to antioxidants, the darker the grape, the higher the antioxidant concentration. And the red and purple grape varieties are highest in anthocyanins. Research shows that these compounds may help reduce the risk of heart disease, cognitive decline, and type 2 diabetes, as well as support healthy weight maintenance and a normal inflammatory response.

Grapes also contain resveratrol, which has been associated with increased nitric oxide (NO) production. This NO isn’t a Bond villain, but a powerful neurotransmitter that helps blood vessels relax and also improves circulation, both of which are associated with heart health.

Resveratrol also acts against tumors, and people are looking into using it to help prevent and treat several kinds of cancer.

One challenge is that, in general, resveratrol has a low bioavailability, which means that even if you consume large quantities, your body can only absorb a little. The good news is resveratrol can interact with fatty acids, so you can increase its bioavailability by consuming foods that contain it (like grapes!) alongside a healthy source of fat.

Grapes and avocado toast, anyone?

Don’t turn your nose up at green grapes just because they aren’t anthocyanin or resveratrol superstars, though. They also deliver a wealth of phytonutrients and antioxidants, most of which belong to the flavanol family of polyphenols.

What Are Grapes Good for?

With all those antioxidants and polyphenols and anthocyanins and NO boosters, you’d expect grapes to provide oodles of health benefits. And luckily, they don’t disappoint.

Grapes and Type 2 Diabetes

Grapes can be very sweet. So you might be surprised to learn that both red and green grapes, as well as unsweetened grape juice, are considered to be low on the glycemic index and have a low glycemic load. Apparently, the fiber, water, and other cofactors in grapes help to create balance and to slow the absorption of the sugars they contain.

And might grapes also contain compounds that are helpful in the prevention of type 2 diabetes? Yes! The skin and seeds of the Vitis vinifera grape can reduce inflammation, prevent cell death, and encourage cell growth in people with type 2 diabetes. They can also reduce oxidative stress (which can damage cells) and improve the way your body metabolizes fats. Ironically, the skin and seeds of grapes, called grape pomace, are typically discarded in the wine-making process. But they are included in many fresh grape juices.

In 2021, researchers discovered that grape pomace can help treat type 2 diabetes. They chose a grape called Carménère (used in Chilean winemaking) and subjected its pomace to hot pressurized liquid extraction (which would make a great name for a spy thriller about a plot to smuggle hot water balloons out of the country).

Several of the polyphenols of interest in the resultant mixture were found to inhibit diabetes-related enzymes. A cluster of proanthocyanidins reduced the activity of two of the enzymes more effectively than the drug acarbose (you might know it as Precose or Prandase) that’s prescribed to accomplish the same thing.

Grapes’ Metabolic Benefits

Metabolic syndrome is a group of conditions, often caused or worsened by diet, that can lead to serious problems like high blood pressure, type 2 diabetes, and heart disease. The polyphenols found in grapes may protect the body from some of the health problems that are often associated with a high-fat, highly processed diet: high LDL cholesterol, high blood sugar, and high blood pressure. The polyphenols also appear to protect the stomach and liver, and can help prevent obesity.

A 2017 study found that a compound extracted from the skin of grapes also improved metabolic markers in rats fed a high-fat diet. Protection included lower cholesterol, decreased insulin resistance, protection against oxidative damage, and reduced inflammation. (Our view on the use of animals in medical research is here.)

Are Grapes Good for the Liver?

In 2012, researchers studied the effects of extracts from the Suosuo grape variety, which is popular in China, on mice whose livers had been damaged by an overactive immune response. They discovered that two substances from the grapes, triterpenoids and flavonoids, seemed to calm this response down. They also reduced the concentrations of harmful chemicals in the liver, helped restore its enzyme activity, and balanced out proteins that control cell death, as well as regulated immune system messengers in the liver.

Eight years later, scientists were able to more or less replicate these findings in humans. A 2020 study found that the flesh and skin of seedless black grapes protected people’s livers from chemical damage more effectively than the standard-of-care drug, silymarin. A particular class of polyphenols known as phenolics decreased stress and inflammation in the liver, which in turn helped to reduce damage and prevent liver scarring.

Grapes and Inflammation

Inflammation in the body is a good thing — until it’s not. Acute inflammation helps with wound healing, but chronic inflammation can cause damage to tissues and organs, lead to diseases like heart disease, type 2 diabetes, and inflammatory bowel disease, and lead to premature aging.

IL-8, also known as Interleukin-8, is a type of protein in the body that plays a major role in the inflammation process. It’s needed to fight infections and heal wounds, but too much IL-8 can also lead to excessive inflammation and potentially contribute to disease. And many people in the modern world suffer from ongoing and excessive chronic inflammation.

A 2016 study found that a Turkish variety of raisins had a significant effect in reducing the release of IL-8. It was discovered that this was mainly because these raisins have seeds, unlike many other types.

In 2020, Romanian researchers tested fresh and fermented extracts of the pomace of a local grape variety, Fetească neagră, as well as pomace from Pinot Noir grapes, to compare their effects on inflammation, oxidative stress, and cancer cell growth in test tubes and in rats with inflammation. Both fresh and fermented pomace extracts reduced oxidative stress caused by inflammation, while the fermented Fetească neagră extracts most powerfully inhibited cancer cell growth.

And a 2023 review article noted that grape extracts’ antioxidant and anti-inflammatory properties make them ideal ingredients in skin care products, due to their potential to improve skin condition and reduce signs of aging.

Grapes’ Antimicrobial Benefits

Grape extracts can also do a number on potentially harmful microbial pathogens. Compounds from grape pomace may help control gum inflammation caused by harmful bacteria, suggesting that you might start seeing grapes in the ingredient list of some brands of toothpaste.

A 2015 study measured the antibacterial and antifungal activity of black grape peel extracts against antibiotic-resistant bacteria and toxin-producing molds. Impressively, researchers found that the extracts significantly inhibited many bacterial and mold species.

Are Grapes and Grape Products Good for You?

Fresh grapes check a lot of nutritional boxes. They contain antioxidants and flavonoids that can help to reduce inflammation and lower heart disease risk. They’re high in fiber, which can promote healthy digestion. And thanks in part to their fiber, which is especially high in grape skins and seeds, grapes’ high sugar content doesn’t appear to be a problem for most people. But what about other grape products, like wine, raisins, jams, juices, and jellies? Do the benefits of consuming those foods outweigh the negatives?

Wine

There’s a lot of evidence that drinking alcohol, even in moderation, can increase your risk of certain cancers and cardiovascular diseases. But recent research has found what appears to be an exception for wine. A 2023 review determined that wine differs from other alcoholic beverages in how it interacts with our cells. Drinking wine in moderation not only does not increase the risk of chronic degenerative diseases, the researchers concluded, but it may actually be associated with health benefits.

One reason could be wine’s high polyphenol content, including but not limited to resveratrol, anthocyanins, catechins, and tannins. Polyphenol content and composition vary from grape to grape and wine to wine, but red wines tend to contain more polyphenols than whites.

Variations in winemaking techniques matter as well when it comes to potential wine health benefits. Fermentation, maceration (grinding up the grapes), aging, clarification (fining and filtering), and the use of preservatives can impact what polyphenols make it into the bottle and how long they remain active.

And there are other well-known catches related to alcohol to consider, too, including its negative effects on mental health and its well-known propensity for addiction.

Grape Juice

So maybe the best way to get all these awesome polyphenols is to drink the juice of the grape before it’s fermented into alcohol. It’s certainly a common way to consume grapes: Grape juice is one of the most popular fruit juice flavors in the US. And it has a similar biochemical makeup as wine, so it could potentially deliver similar health benefits minus the alcoholic toxicity and danger of dependence.

The downside here is that many brands of grape juice contain added sugar. If you want to drink grape juice, you may want to consider making your own, so you can be sure the final product is 100% juice.

But — even if you find a brand with zero added sugar, or make your own, the juice still may deliver large concentrations of sugar to your body all at once. That’s because it’s missing the fiber that can act to slow down absorption, meaning it could trigger an unhealthy blood sugar spike in some people.

Grape Jam and Jelly

Grape jams and jellies are another popular way to consume grapes. And for a fruit that’s already so sweet on its own, you might be shocked to discover how much refined sweetener is often added to the final product. Many brands of grape jam and jelly use high-fructose corn syrup manufactured from bioengineered (GMO) corn. They may also contain other harmful additives, such as artificial colors, flavors, and preservatives.

The bottom line here? If you want to derive the maximum health benefits from grapes, the safest way is to consume them in their whole food form.

Other Downsides and Risks of Eating Grapes

That’s not to say that all grapes are safe for all people. Many grapes (as well as the wines, raisins, and condiments made from them) contain concerning levels of pesticide contamination. So much so, in fact, that grapes have “earned” a spot on the Environmental Working Group’s “Dirty Dozen” list, meaning they are among the 12 types of produce you should consider purchasing organically. That goes for grape products as well.

While rare, grape allergy is also a thing for some people — although those who react in an allergic fashion to grapes are more likely to be experiencing oral allergy syndrome, a condition that affects some people who are already allergic to different types of pollen.

And then there’s the issue of FODMAPs — short-chain carbohydrates that are poorly absorbed and can trigger gastrointestinal symptoms in people with irritable bowel syndrome. Grapes are generally considered low-FODMAP, but the amount of FODMAPs may depend on the grape variety and how they’re processed. Raisins and sultanas may also contain more FODMAPs than raw grapes because their sugars are concentrated (and primarily fructose and glucose).

Grapes Can Be Great!

Grapes are packed with essential vitamins, minerals, and powerful antioxidants. In their whole food form, they offer a host of health benefits, including lessening symptoms of metabolic syndrome, providing anti-inflammatory properties, protecting the liver, and fighting harmful pathogens.

While there are some risks associated with consuming nonorganic grapes in particular, for most people they’re an excellent fruit to include in a balanced diet. And a one-cup serving can be a sweet, juicy, and delicious way to help you meet the five-a-day recommendation of fruits and vegetables.

The post Are Grapes Good for You? appeared first on Food Revolution Network.

It took over 100 years for scientists to recognize the tremendous healing potential of rutin. Nobel Prize-winning Hungarian biochemist Albert Szent-Györgyi was working with vitamin C and noticed that many of the foods containing vitamin C had more of a health-boosting punch than they should have.

He determined that there must be some other compound(s) in plants acting synergistically with vitamin C. As a result, he began looking for what he called “vitamin P” in a mixture of Hungarian red peppers (which gave the theoretical vitamin its letter) and lemon juice.

If you’re rootin’ for rutin to fit the bill, congratulations! While “vitamin P” never really caught on (eventually, it was discovered that rutin, along with many other plant compounds, were totally different from vitamins, and were dubbed “phytochemicals”), it did show that rutin is a nutritional powerhouse, with more health benefits being discovered all the time.

If rutin is already on your radar, you may have come across it as a supplement recommended for a variety of health conditions, including varicose veins and inflammation. You may also have heard about it in association with buckwheat, one of the plants highest in the nutrient.

But there’s much more to rutin’s uses than just vein-free skin. In this article, we’ll dive into the world of rutin, exploring its top health benefits, where and how to get it in food, and whether you need to take supplements to get enough.

What Is Rutin?

Rutin is a bioflavonoid formed by the flavonol quercetin and the disaccharide rutinose, which are plant chemicals that offer health benefits when consumed. Technically, rutin is what’s known as a glycoside, meaning it contains a sugar group that’s bonded to a non-sugar group (kind of like a merger of The Partridge Family and Death Cab for Cutie). Some plant-derived glycosides are poisonous to humans, but luckily, rutin isn’t among them.

As we’ve seen, it’s also sometimes referred to as vitamin P, but to be fair, it’s not the only compound that is. Rather than pick one flavonoid and give it all the glory, it’s more accurate to say that the whole lot of them, collectively, act as a “vitamin P” which increases the beneficial effects produced by citrus compounds.

Rutin is also an antioxidant powerhouse and may contribute to healing in the body. When combined with vitamin C, both antioxidants increase their effectiveness; the action of C combined with P exceeds the sum of the two compounds on their own. (Like how Paul McCartney and John Lennon were great songwriters individually, but transcendent as a duo. Or Abbott and Costello. Or — you get the idea.)

What Is Rutin Good for?

The more researchers look, the more good things they’re discovering about how rutin can support your health. But we have to be a little cautious here since many of the studies involved either test tubes or animals. That means the results may not translate directly into human benefit. (And here’s what we think about the use of animals in medical research.)

That said, there are some promising human trials on rutin. Even though they’re small, with not a lot of participants, the benefits of rutin have been so great that they were detectable even in small numbers.

One further disclaimer: Although there are a lot of studies that have looked at the health applications of rutin, they’ve all used rutin or rutinosides in supplemental form, and not in the context of whole foods. So just keep that in mind since, as with any plant compound, rutin likely works best synergistically with the variety of vitamins, minerals, and phytochemicals that are found in whole foods.

Rutin and Vascular Health

Rutin has been shown in a number of clinical trials to produce modest improvements in severe symptoms of chronic venous insufficiency (CVI), a condition in which blood pools in the veins rather than circulating freely back to the heart. (I like to imagine the endothelial cells crooning the Back Street Boys’ “Back to Your Heart” over a soulful saxophone solo by the one-way valves in the legs.)

A 2016 meta-analysis found that rutin (also referred to as rutosides) reduced swelling, leg pain, and discomfort in people with varicose veins. To determine the mechanisms involved, researchers fed rutoside extracts to arthritic rats. They discovered that the extracts blocked certain genes responsible for inflammation in cells, and also inhibited the release of certain molecules that cause swelling.

Rutin’s Anti-Inflammatory Benefits

Inflammation and oxidation are at the root of many chronic diseases, so substances that protect you from those processes can deliver significant health benefits. An obviously cruel 2021 study out of India explored whether rutin could protect the livers, kidneys, and brains of rats from damage. The researchers administered different doses of rutin to the rats for six days and then exposed them to harmful substances called D-galactosamine and lipopolysaccharide on the sixth day.

After those exposures, several liver and kidney blood markers increased significantly, and tissue samples also showed signs of increased toxicity. But the rats who were given rutin beforehand showed fewer harmful effects.

The reason for this protection, according to current scientific understanding, is that rutin protects tissues by reversing inflammation, blocking the action of free radicals, and stopping healthy cells under attack from self-destructing prematurely.

Rutin Brain Benefits

Rutin has been found to have numerous positive effects on the brain, including reducing inflammation, protecting against toxic buildups of proteins, and improving the function of important enzymes. Researchers hope that rutin can help treat neurodegenerative diseases, including Alzheimer’s, Parkinson’s, Huntington’s, and prion diseases (I looked this up; they’re infectious brain diseases and not caused by being in an accident with a Prius).

Iranian scientists in 2018 conducted a pair of experiments to assess rutin’s potential to protect the brain and nervous system from damage. In the first one, rutin was found to enhance cell viability, reduce the production of reactive oxygen species (ROS) and lipid peroxidation (a nasty process that’s basically a cascade of molecular damage), and decrease DNA damage and self-directed cell death. These results suggest that rutin may have neuroprotective properties and could help prevent and treat strokes and neurodegenerative disorders.

Their second experiment investigated the effects of rutin in rats with reduced blood flow to the brain. The flavonoid protected against oxidative damage, inhibited apoptotic mechanisms (that is, it stopped cells from self-destructing when there was no need), and reduced DNA damage.

A 2023 mice study also explored the potential therapeutic effects of rutin and its related flavonoid, quercetin, in Alzheimer’s disease. Researchers found that both compounds may have beneficial effects on various markers of Alzheimer’s, including antioxidant enzyme activity, BACE1 activity (that’s an enzyme that’s key in the production of damaging amyloid plaque), and amyloid precursor protein (APP) expression, neurodegeneration, and inflammation.

In plain English, it looks like rutin is very good for your brain.

Rutin and Type 2 Diabetes

A 2016 study investigated the effects of rutin on diabetic neuropathy in rats. Rutin showed significant protection by reducing pain sensitivity and improving nerve conduction. It also lowered blood glucose and reduced oxidative stress and inflammation. In fact, rutin actually outperformed insulin, making it a promising treatment for diabetic neuropathy.

Then in 2023, a randomized, placebo-controlled trial examined what happened when adults with type 2 diabetes took 500 mg of rutin every day for three months. One group got the rutin, and the other got a placebo. The rutin group improved on a bunch of different disease markers, including fasting blood glucose, insulin, A1c (a long-term and stable measure of blood sugar), and various cholesterol levels and ratios.

Rutin and Cancer

Rutin is also getting more and more attention as a potential cancer fighter. It has demonstrated the ability to inhibit the growth of various cancers and tumors, including breast, colon, lung, and prostate cancers. Rutin regulates key signaling pathways involved in cancer development and apoptosis (cell death). And when used alone or with other drugs, rutin shows promise in preventing tumor growth, reducing drug resistance, and minimizing chemotherapy side effects.

In a 2021 test-tube study, rutin showed strong inhibitory effects against the Jab1 oncogene. This pugilistic-sounding gene inactivates proteins that suppress tumors, so switching it off allows the body to fight cancers with its own innate tools.

A 2022 test-tube study also explored mechanisms by which rutin slowed the progression of pancreatic cancer. Researchers found the flavonoid significantly inhibited pancreatic cancer cells’ proliferation and migration while promoting their self-destruction.

Rutin Heart Benefits

Rutin appears to counteract the harmful effects of certain pollutants on the heart. A 2021 study exposed rats to two environmental toxins, bisphenol-A (BPA) and dibutyl phthalate, on the cardiovascular system. Researchers found that these pollutants caused oxidative stress and inflammation in the heart. However, when the rats were given rutin, it prevented these negative effects by activating certain protective pathways in the heart.

What Foods Contain Rutin?

So now that you know how powerful rutin is for your health, where can you get it?

Unsurprisingly, you can get rutin from many different kinds of plant foods.

1. Buckwheat

Buckwheat has the most dietary rutin of any plant studied so far. Tartary buckwheat malt and sprouts, in particular, can deliver as much as 54 grams per kilogram.

To find out more about the wonderful world of buckwheat, including the different kinds and how to include it in your diet, check out our article on buckwheat.

2. Apples

All apples contain rutin, but there are wide variations in how much. Some varieties have up to 20 times the rutin of others. Of the popular types you can find in the US, Granny Smith is the winner, although some Indian varieties, such as Lal Ambri, contain almost twice as much.

3. Olives

Both green and black olives are good sources of rutin — although a 2017 study gave green a slight edge.

For more information on the health implications of eating olives, including whether their salt content is a problem, check out our article here.

4. Teas

Moringa leaves owe much of their well-deserved reputation as rich sources of antioxidants to their rutin content. And matcha green tea also delivers a significant amount of rutin when brewed.

5. Citrus

Citrus fruits contain both rutin and vitamin C, in that synergistic combination that so interested the Hungarian biochemist, Szent-Györgyi. Mandarin oranges are a particularly rich source of rutin.

6. Stone Fruits

Stone fruits, including apricots, cherries, plums, and peaches, are also great places to get your dietary rutin. If you can find an Eastern European plum variety called “Rausvė,” you’ll have met the rutin champion of stone fruits.

7. Asparagus

If you’re more of a veggie person looking for rutin, then asparagus is your friend. Green asparagus is a rich source and can contain between 1.51 and 7.29 mg/g.

Rutin Supplements

Aside from specific foods that contain rutin, supplements containing rutin are also available, often in combination with vitamin C, citrus bioflavonoids, and quercetin.

However, even though it’s a potent antioxidant, health authorities like the FDA and the World Health Organization have never established a specific recommended dietary allowance for rutin. That said, it may be useful for some conditions, including one mentioned in the health benefits section of this article.

So how much rutin should you take? Is there such a thing as too much rutin?

Well, Spanish health authorities suggest an upper daily limit of 600 mg of supplements that contain both rutin and quercetin. As most rutin supplements deliver 500 mg, they’re under that limit.

Nevertheless, side effects of rutin supplementation may still occur. Rutin supplements could, at least in some rare cases, cause blurred vision, dizziness, headache, nervousness, slow or fast heartbeat, and swollen feet and ankles.

Rutin may also interact with some medications, such as blood thinners like warfarin. It’s usually a good idea to consult with a health care professional before starting any new supplement or medication.

Ultimately, if you want the health benefits of rutin without potential side effects, and in the synergistic combinations that inspired Albert Szent-Györgyi to search for the amazing vitamin P, you may want to get it from your diet with whole plant foods.
