Black Raspberries vs. Oral Cancer

Black raspberries may cause complete clinical regression of precancerous oral lesions (oral intraepithelial neoplasia).



Carnitine, Choline, Cancer, & Cholesterol: The TMAO Connection

Expanding on the subject of my upcoming appearance on The Dr. Oz Show, a landmark new article in the New England Journal of Medicine shows that choline in eggs, poultry, dairy, and fish produces the same toxic TMAO as carnitine in red meat—which may help explain plant-based protection from heart disease and prostate cancer.



Do Fruit & Nut Bars Cause Weight Gain?

Despite the caloric density of both nuts and dried fruit, they do not appear to lead to the expected weight gain.



Flesh and Fructose

Meat and sugar increase uric acid levels, which are associated with increased risk of gout, hypertension (high blood pressure), obesity, prediabetes, diabetes, kidney disease and cardiovascular disease.



Whole Grains May Work as Well as Drugs

The consumption of three portions of whole grains a day appears as powerful as high blood pressure medications in alleviating hypertension.



Metabolic Syndrome and Plant-Based Diets

Plant-based diets appear to protect against metabolic syndrome, also known as syndrome X, which is characterized by the so-called “deadly quartet”—abdominal obesity, high fasting sugars, high triglycerides, and high blood pressure.



Unsweetening the Diet

All sweeteners—natural and artificial; caloric and non-caloric—help maintain cravings for intensely sweet foods.



Neurobiology of Artificial Sweeteners

The disconnect between sweetness sensations coming from our tongue, and the lack of a caloric feedback loop in the gut, may result in overeating.



How Diet Soda Could Make Us Gain Weight

People consuming low-calorie sweeteners may overcompensate by eating more than they otherwise would.



Standing Up for Your Health

Prolonged daily sitting is associated with a shorter lifespan, even in those who exercise regularly. Standing and treadmill desks are two potential solutions for office workers.



The Best Baby Formula

Exclusive breastfeeding for a full six months may, ironically, improve our children’s taste for vegetables—whereas children fed formula grow up with increased rates of inflammatory diseases such as asthma, cancer, and diabetes.



Modern Meat Not Ahead of the Game

Since chronic inflammation underlines many disease processes, and saturated fat appears to facilitate the endotoxic inflammatory reaction to animal products, researchers have looked to wild animals for less unhealthy meat options.



Prostate vs. Plants

All men should consider eating a prostate-healthy diet, which includes legumes (beans, peas, lentils, soy); certain vegetables (like garlic and onions); certain seeds (flax seeds); and the avoidance of refined grains, eggs, and poultry.



Slimming the Gecko

A workplace dietary intervention study at GEICO corporate headquarters demonstrates the power of plant-based eating.



To Snack or Not to Snack?

A review of the best available science examining the impact of eating frequency on both weight and health.



Diet Pills Do Fat a Lot of Good

Common slimming supplements are found to be ineffective, whereas a diet centered on whole plant foods is described as perhaps the safest approach to weight control.



Waist Circumference Less than Half Your Height

Waist-to-height ratio may be a better predictor of disease than body mass index.



Cattlemen’s Association Has Beef with Study

Meat consumption is not only associated with weight gain, but specifically abdominal obesity, which is the most metabolically concerning.



Meat and Weight Gain in the PANACEA Study

In one of the largest nutrition studies ever, total meat consumption was significantly associated with weight gain in men and women—and the link remained even after controlling for calories.



Diet vs. Exercise for Weight Loss

When asked whether food and beverage consumption, or physical activity, was more important, the majority of people get the answer wrong.



The Ice Diet

The water content of plant foods may help explain why those eating plant-based diets are, on average, so slim. Can ice be thought of as having even “fewer” calories than water, since the body has to warm it up?



Tipping Firmicutes to Bacteroidetes

Certain phytonutrients may tip the balance of healthy gut bacteria in favor of flora associated with improved weight control.



Boosting Good Bacteria in the Colon Without Probiotics

Certain good bacteria in our gut can turn the fiber we eat into an anti-inflammatory, anti-cancer compound—called butyrate—that we absorb back into our system. We may be able to boost the number of butyrate-producing bacteria by eating a plant-based diet.



Fawning over Flora

The good bacteria in our gut can digest the fiber we eat, and turn it into an anti-obesity compound—called propionate—that we absorb back into our system.



Fat Burning via Flavonoids

Flavonoid phytonutrients (found concentrated in citrus, berries, red onions, beans, green tea, grapes, and cocoa) may boost metabolism enough to significantly slim one’s waistline.



Fat Burning Via Arginine

The arginine content of nuts may explain their metabolism-boosting effects—though, in a list of the top food sources of arginine, nuts don’t even make the top ten.



Testing the Fat-Burning Theory

Finally, there’s a solution to the mystery of why nuts don’t seem to make people gain weight. It appears to be a combination of factors—including a boost to our metabolism, which results in us burning more of our own fat stores.



Testing the Dietary Compensation Theory

An elegant study is presented, testing the appetite-suppressing effects of walnuts.



Testing the Pistachio Principle

If the fecal fat losses associated with undigested pieces of nuts (due to inadequate chewing), and the tedium of shelling them in the first place, help account for why nuts don’t tend to lead to weight gain, then studies on nut butters would presumably turn out differently.



Solving the Mystery of the Missing Calories

A few theories have been proposed as to why nuts don’t appear to contribute to weight gain, including the “pistachio principle” and the fecal excretion theory.



Nuts and Obesity: The Weight of Evidence

Nut consumption does not appear to lead to the expected weight gain.



Uprooting the Leading Causes of Death

Death in America is largely a foodborne illness. Focusing on studies published just over the last year in peer-reviewed scientific medical journals, Dr. Greger offers practical advice on how best to feed ourselves and our families to prevent, treat, and even reverse many of the top 15 killers in the United States.



The Acne-Promoting Effects of Milk

Dairy is considered a major cause of the acne epidemic, and other more serious chronic diseases in the Western world, due to the “abuse” of the mammalian postnatal signaling system by widespread cow milk consumption.



Vegetarians vs. Healthy Omnivores

Even after controlling for a variety of dietary and nondietary factors, those eating plant-based diets appear to have lower overall cancer rates.



The Dangers of Broccoli?

A case report of a woman after Roux-en-Y gastric bypass surgery trying to eat right.



Atkins Diet: Trouble Keeping It Up

A case report in the Journal of the Academy of Nutrition and Dietetics (formerly Journal of the American Dietetic Association) of a man who went on the Atkins diet, lost his ability to have an erection—and nearly lost his life.



Amla vs. Diabetes

For a dollar a month, Indian gooseberry (amla) powder may work as well as a leading diabetes drug—without the side effects.



Dietary Guidelines: The First 25 Years

How have the Dietary Guidelines for Americans evolved over the years since they were first issued in 1980?



Nation’s Diet in Crisis

Survey reveals the vast majority of Americans are not eating healthy, even by U.S. Dietary Guideline standards.
