  • How Foods Are Tested for Depression

    What is the science behind the marketing of foods for antidepressant effects? If you go online, you can see claims about “coconut water being beneficial for depression,” and studies are even cited. You can see it yourself in black and white—“Young coconut water ameliorates depression”—as shown at 0:16 in my video Flashback Friday: Coconut Water […]

  • Heavy Metal Detox Diet

    What dietary change can simultaneously help detoxify mercury, lead, and cadmium from the body? I’ve previously explored the issue of lead contamination in calcium supplements, such as bonemeal, but bone meal isn’t all that can be contaminated. “Substantial quantities of lead have been reported in some over-the-counter calcium supplement preparations,” and testing has revealed continued […]

  • Blueberry Blocking Effects of Yogurt

    What happened when researchers tried to tease out what’s in dairy that interferes with the health benefits of berries and tea? A trio of Harvard studies that followed more than 100,000 women for more than a decade found that those consuming the most anthocyanins—the brightly colored pigments found in blueberries, strawberries, and other berries—had an […]

  • Dinosaur Kale and Red Cabbage Put to the Test

    Dinosaur kale and red cabbage are put to the test.  LDL cholesterol is bad, but oxidized LDL may be even worse. What role might our diet play? “Increased fruit and vegetable consumption has been reported to reduce the risk of developing CVD”—cardiovascular disease, heart attacks, and strokes. That may be due in part to all […]

  • Sports Drinks Are Neither Safe Nor Effective

    Commercial influences may have corrupted the American College of Sports Medicine’s hydration guidelines. If you had to name the greatest medical advance over the past two centuries, what would you pick? Smallpox vaccine jumped to my mind, then I remembered it was discovered back in the 1700s. The British Medical Journal compiled a list of […]

  • Water vs. Coconut Water vs. Sports Drinks for Athletes

    Coconut water is tested head-to-head against plain water and sports drinks in athletes. As you may know, I’ve previously reviewed the evidence on coconut oil and coconut milk that suggests neither is good for you, but what about coconut water? When I first learned about athletes using coconut water as a type of natural Gatorade, […]

  • Is Soy Harmful, Harmless, or Helpful for Fibroids?

    When it comes to uterine fibroids, is soy harmful, harmless, or helpful? About one in four women will eventually suffer from fibroids, most commonly manifesting as excessively heavy periods, pain, or pressure. Why might you feel pressure? Because, as you can see at 0:17 in my video Should Women with Fibroids Avoid Soy?, you may […]

  • Do Any Benefits of Alcohol Outweigh the Risks?

    What would happen if you effectively randomized people at birth to drink more or less alcohol their whole lives? Would they get more or less heart disease? Once you remove the “systematic error” of misclassifying former drinkers as if they were lifelong abstainers from studies on alcohol and mortality, moderate alcohol consumption, like a glass […]

  • Is It Better to Drink a Little Alcohol Than None at All?

    Even if alcohol causes cancer and there is no “French paradox,” what about the famous J-shaped curve, where excessive drinking is bad, but light drinkers appear to actually have lower mortality than abstainers? “Why do we not see the corporate interests of the alcohol industry as clearly as we see those of the tobacco industry?” […]

  • The Best Source of Resveratrol

    Is there any benefit to resveratrol? If so, should we get it from wine, grapes, peanuts, or supplements? “Alcohol is a neurotoxin which can cause brain damage…[and] can cause cancer,” so perhaps the “consumption of alcohol…cannot be considered a healthy lifestyle choice” since it’s an addictive carcinogen. Cancer is only killer number two, though. Killer […]

  • Can Alcohol Cause Cancer?

    If even light drinking can cause cancer, why don’t doctors warn their patients about it? As I discuss in my video Can Alcohol Cause Cancer?, we’ve known about “the possible association of the consumption of alcohol with excessive mortality from cancer” for more than a hundred years. Though there is “accumulating evidence that alcohol drinking […]

  • Apple Peels Put to the Test for Chronic Joint Pain

    Are the health benefits associated with apple consumption simply due to other healthy behaviors among apple-eaters? Regular apple intake is associated with all sorts of benefits, such as living longer and, more specifically, a lower risk of dying from cancer. At 0:17 in my video Apple Peels Put to the Test for Chronic Joint Pain, […]

  • Does Chocolate Cause Acne? 

    What are the effects of dairy products, sugar, and chocolate on the formation of pimples? Acne affects nearly one in ten people globally, “making it the eighth most prevalent disease worldwide.” What is nutrition’s role? If we go back a century, dermatology textbooks “recommended dietary restriction”—for example, advising those with acne to avoid foods like […]

  • Does Laptop Wi-Fi Affect Fertility?

    Should laptops not be on laps? What is the effect of WiFi exposure on sperm motility and DNA damage? “It is impossible to imagine a modern socially-active man who does not use mobile devices and/or computers with Wi-Fi function.” Might cell phones or wireless internet be harmful for male fertility? You may recall that I’ve […]

  • Millions of Years of Healthy Life Lost Due to Cannabis

    Every year, cannabis is estimated to result in two million years of healthy life lost due to disability. How much is that compared with alcohol and tobacco? “The popular notion seems to be that marijuana is a harmless pleasure,” but what are the potential adverse effects of marijuana use? That’s not an easy question to […]

  • Dr. Greger’s Daily Dozen Healthiest of Healthy Foods 

    In my book How Not to Die, I center my recommendations around a Daily Dozen checklist of everything I try to fit into my daily routine.  In my book How Not to Die, I suggest we try to center our diets around whole plant foods. Some plants are healthier than others, though. Apparently, you can live for extended periods eating practically nothing but white potatoes, for example, […]

  • Tomato Sauce Put to the Test for Prostate Cancer

    What happened when cancer patients were given three quarters of a cup of canned tomato sauce every day for three weeks? “Occasionally…positive things happen in the field of cancer prevention science to popular, good-tasting foods.” Cruciferous vegetables like broccoli are wonderful, but they may be “a hard food for the public to swallow.” By contrast, […]

  • Dr. Gundry’s The Plant Paradox Is Wrong

    A book purported to expose “hidden dangers” in healthy foods doesn’t even pass the whiff test. I started getting emails about The Plant Paradox, a book purporting to expose “the hidden dangers in ‘healthy’ foods that cause disease and weight gain”—foods like beans, whole grains, and tomatoes. Hidden dangers? The author’s talking about lectins in […]

  • Dietary Cure for Hidradenitis Suppurativa

    What is the role of dairy- and yeast-exclusion diets on arresting and reversing an inflammatory autoimmune disease? A landmark study suggested that exposure to dietary yeast, like baker’s yeast, brewer’s yeast, and nutritional yeast, may worsen the course of Crohn’s disease, an autoimmune inflammatory bowel disease. The reason the researchers even thought to do the […]

  • Is Candida Syndrome Real?

    Does the presence of Candida in stool correlate with “Candida-hypersensitivity” symptoms, such as headaches and tiredness? And what happens when people are placed on a high-sugar diet? Despite its extensive use in the brewing and baking industries, only about 5 percent of healthy people—1 in 20—have anti-yeast antibodies in their bloodstream, whereas that percentage is […]

  • How Much Arsenic in Rice Is Too Much?

    What are some strategies to reduce arsenic exposure from rice? Those who are exposed to the most arsenic in rice are those who are exposed to the most rice, like people who are eating plant-based, gluten-free, or dairy-free. So, at-risk populations are not just infants and pregnant women, but also those who may tend to […]

  • How Risky Is the Arsenic in Rice?

    Getting rice down to the so-called safe water limit for arsenic would still allow for roughly 500 times greater cancer risk than is normally considered acceptable. Given the level of arsenic in rice, how could we figure out how much rice is too much? There are no U.S. standards for arsenic in rice, even though […]

  • Arsenic in Rice Milk, Rice Krispies, and Brown Rice Syrup

    I recommend people switch away from using rice milk For kids and teens, the amount of arsenic flowing through their bodies was found to be about 15 percent higher for each quarter cup of rice consumed per day, and a similar link was found in adults. A study of pregnant women found that consuming about […]

  • Arsenic in Infant Rice Cereal

    When it comes to rice and rice-based products, pediatric nutrition authorities have recommended that arsenic intake should be as low as possible. “The US Food and Drug Administration (FDA) has been monitoring the arsenic content in foods” for decades, yet despite the “well-established science describing the health risks associated with arsenic exposure, no standards have […]

  • Where Does the Arsenic in Rice, Mushrooms, and Wine Come From?

    What happens when our crops are grown in soil contaminated with arsenic-based pesticides and arsenic drug-laced chicken manure? When arsenic-containing drugs are fed to chickens, not only does the arsenic grow out into their feathers, which are then fed back to them as a slaughterhouse byproduct, but the arsenic can also get into their tissues […]

  • Açaí vs. Wild Blueberries for Artery Function

    “Plant-based diets…have been found to reduce the risk of cardiovascular disease” and some of our other leading causes of death and disability. “Studies have shown that the longest living and least dementia-prone populations subsist on plant-based diets.” So why focus on açaí berries, just one plant, for brain health and performance? Well, “foods rich in […]

  • The Antioxidant Power of Açaí vs. Apples

    There are so many açaí products on the market now, from frozen pulp in smoothie packs to freeze-dried powder and supplements. How is it eaten traditionally? “In the Brazilian Amazon, the Indian tribes of the forest cut down the tree and eat the palm heart…then urinate on the rest of the tree to attract a […]

  • Topical Green Tea for Acne and Fungal Infections

    Which plant should we use for which skin disease? That’s the topic of my video Natural Treatment for Acne and Fungal Infections. Thousands of studies have been published to date about the health effects of green tea, but it wasn’t until fairly recently that researchers began to look at the possibility of using green tea […]

  • The Flint Lead Crisis May Be the Tip of the Iceberg

    Back in the 1960s, a Pulitzer prize-winning scientist described the problem of childhood lead poisoning as “so well defined, so neatly packaged with both causes and cures known, that if we don’t eliminate this social crime, our society deserves all the disasters that have been forecast for it.” As I discuss in my video Lead […]

  • How the Lead Paint and Gas Industries Got Away with It

    We have known for thousands of years that lead can be toxic and for more than a century that children could be poisoned by lead paint. Since those first cases, the “lead industry has mobilized against the advances of science,” as I discuss in my video How the Lead Paint Industry Got Away with It. […]

  • What Happens if You Have Red Wine or Avocados with a Meal?

    Whole plant sources of sugar and fat can ameliorate some of the postprandial (after meal) inflammation caused by the consumption of refined carbohydrates and meat. Studies have shown how adding even steamed skinless chicken breast can exacerbate the insulin spike from white rice, but fish may be worse. At 0:18 in my video The Effects […]

  • Boosting Antiviral Immune Function with Green Tea

    Unlike most antiviral drugs, green tea appears to work by boosting the immune system to combat diseases such as genital warts (caused by HPV) and the flu (caused by the influenza virus). According to one study, “The belief in green tea as a ‘wonder weapon’ against diseases dates back thousands of years.” I’ve talked about […]
