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.

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.

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.



Can Oatmeal Reverse Heart Disease?

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

Which foods should we eat and avoid to prevent and treat acid reflux before it can place us at risk for Barrett’s esophagus and cancer?



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.



Bowel Wars: Hydrogen Sulfide vs. Butyrate

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?



Stool pH & Colon Cancer

Fermentation of fiber in the gut may help explain the dramatic differences in colorectal cancer incidence around the world.



Preventing Ulcerative Colitis with Diet

The toxic rotten egg gas hydrogen sulfide may explain why animal protein is associated with inflammatory bowel disease.



Plant-Based Workplace Intervention

Employee wellness programs may help boost the corporate bottom line.



The Problem with the Paleo Diet Argument

The Paleolithic period represents just the last two million years of human evolution. What did our bodies evolve to eat during the first 90% of our time on Earth?



Preventing Alzheimer’s Disease with Plants

If foods like berries and dark green leafy vegetables have been found protective against cognitive decline, why aren’t they recognized as such in many guidelines?



Preventing Crohn’s Disease with Diet

Diets centered around whole plant foods may help prevent Crohn’s disease through the benefits of fiber on the maintenance of intestinal barrier function and the avoidance of certain processed food additives such as polysorbate 80.



Can Diet Protect Against Kidney Cancer?

Plant-based diets appear to protect against renal cell carcinoma both directly and indirectly.



If Fructose Is Bad, What About Fruit?

Does the fructose naturally found in fruit and fruit juice have the same adverse effects as excess “industrial fructose” (table sugar and high fructose corn syrup) and if not, why not?



Juicing Removes More than Just Fiber

The majority of polyphenol phytonutrients may be bound to fiber, helping to explain the marked difference in health impacts between whole fruit and fruit juice.



Lifestyle Medicine Is the Standard of Care for Prediabetes

Lifestyle modification is considered the foundation of diabetes prevention. What dietary strategies should be employed, and why don’t more doctors use them?



Telomeres: Cap It All Off with Diet

Is the reversal of cellular aging Dr. Dean Ornish demonstrated with lifestyle changes due to the plant-based diet, the exercise or just to the associated weight loss?



Garlic & Raisins to Prevent Premature Birth

Consumption of even small amounts of garlic or raisins are associated with significantly lower risk of pregnant women going into premature labor or having their water break too soon.



Barriers to Heart Disease Prevention

According to the Director of the famous Framingham Heart Study, the best way to manage cholesterol and heart disease risk is with a more plant-based diet. Why then, don’t more doctors advise their patients to change their diets?



How to Prevent Prediabetes in Children

Prediabetes is a disease in and of itself, associated with early damage to the eyes, kidneys, and heart. The explosion of diabetes in children is a result of our epidemic of childhood obesity. A plant-based diet may help, given that vegetarian kids grow up not only taller, but thinner.



How to Prevent Prediabetes from Turning into Diabetes

Approximately 1 in 3 Americans have prediabetes, but only about 1 in 10 knows it. What works better at preventing it from turning into full-blown diabetes—drugs or diet and exercise?

Breast Cancer and Constipation

The reason why women who have more frequent bowel movements appear to be at lower risk for breast cancer may be because bile acids absorbed from our intestines concentrate in the breast and have a estrogen-like tumor promoting effect.
