Why does our immune system confuse unhealthy diets with dysbiosis—an overrun of bad bacteria in our colon?



Microbiome: The Inside Story

The microbiome revolution in medicine is beginning to uncover the underappreciated role our healthy gut bacteria play in nutrition and health.



What Are the Healthiest Foods?

Based on the Dietary Guidelines for Americans, which foods best supply shortfall nutrients while avoiding disease-promoting components?



Everything in Moderation? Even Heart Disease?

Health authorities appear to have taken the patronizing view that the public can’t handle the truth and would rather the science be watered down.



Treating Ulcerative Colitis with Diet

If the avoidance of sulfur-rich proteins and food additives can help prevent inflammatory bowel disease, might similar dietary changes help prevent relapses of ulcerative colitis?



Liquid Calories: Do Smoothies Lead to Weight Gain?

If our body doesn’t register liquid calories as well, why are blended soups more satiating than the same ingredients eaten in solid form?



Green Smoothies: What Does the Science Say?

Might disrupting the fiber by blending fruit result in overly rapid sugar absorption?



Are Green Smoothies Bad for You?

Eating intact grains, beans, and nuts (as opposed to bread, hummus, and nut butters) may have certain advantages for our gut flora and blood sugar control, raising questions about blending fruits and vegetables.



Putrefying Protein and “Toxifying” Enzymes

Certain gut bacteria can “retoxify” carcinogens that your liver successfully detoxified, but these bacteria can be rapidly suppressed by simple dietary changes.



How May Plants Protect Against Diabetes?

Protective properties of whole plant foods against diabetes include antioxidants, lipotropes, fiber, and the ability to suppress the estrogen-producing bacteria in our gut.



Food as Medicine: Preventing and Treating the Most Dreaded Diseases with Diet

Dr. Greger has scoured the world’s scholarly literature on clinical nutrition and developed this new presentation based on the latest in cutting edge research exploring the role diet may play in preventing, arresting, and even reversing some of our most feared causes of death and disability.



Does Rye Bread Protect Against Cancer?

The lignans in rye could explain why rye intake is associated with lower breast and prostate cancer risk.



Does Fiber Really Prevent Diverticulosis?

The parable of the tiny parachute explains the study that found no relationship between dietary fiber intake and diverticulosis.



Diverticulosis: When Our Most Common Gut Disorder Hardly Existed

More than two-thirds of Americans over age 60 have diverticulosis, but it was nearly unknown a century ago, and remained extremely rare among populations eating whole food plant-based diets.



Preventing Brain Loss with B Vitamins?

One week on a plant-based diet can significantly drop blood levels of homocysteine, a toxin associated with cognitive decline and Alzheimer’s disease. Without vitamin B12 supplementation, though, a long-term plant-based diet could make things worse.



Should You Sit, Squat, or Lean During a Bowel Movement?

Squatting and leaning can help straighten the anorectal angle, but a healthy enough diet should make bowel movements effortless regardless of positioning.



How Many Bowel Movements Should You Have Every Day?

Most people have between 3 bowel movements a day and 3 a week, but normal doesn’t necessarily mean optimal.



Diet and Hiatal Hernia

Straining at stool over time may force part of the stomach up into the chest, contributing to GERD acid reflux disease. This may explain why hiatal hernia is extremely rare among populations eating high-fiber diets.



Solving a Colon Cancer Mystery

Even though modern African diets may now be as miserably low in fiber as American diets, Africans still appear to have 50 times less colorectal cancer than Americans (our second leading cancer killer).



The Safety of Heme vs. Non-Heme Iron

Heme iron, the type found predominantly in blood and muscle, is absorbed better than the non-heme iron that predominates in plants, but may increase the risk of cancer, stroke, heart disease, and metabolic syndrome.

Less than 3% of Americans meet the daily recommended fiber intake, despite research suggesting high-fiber foods such as whole grains can affect the progression of coronary heart disease.



Diet and GERD Acid Reflux Heartburn

How to Prevent Kidney Stones with Diet

Interventional studies support the population data that animal protein consumption appears to markedly increase the risk of kidney stones.

Sulfur dioxide preservatives in dried fruit, sulfites in wine, and the putrefaction of undigested animal protein in the colon can release hydrogen sulfide, the rotten egg gas associated with inflammatory bowel disease.



How to Prevent a Stroke

Insufficient intake of fiber-rich foods may lead to the stiffening of our arteries associated with risk of having a stroke.



How Much Fruit Is Too Much?

Does the threshold for toxicity of fructose apply to fruit or just to added industrial sugars such as sucrose and high fructose corn syrup?



Can Oatmeal Help Fatty Liver Disease?

Is whole grain consumption just a marker for healthier behaviors, or do whole grains have direct health benefits?
