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



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.



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.



How to Prevent High Blood Pressure with Diet

High blood pressure, the #1 killer risk factor in the world, may be eliminated with a healthy enough diet.



Antioxidants and Depression

Neither antioxidant or folic acid supplements seem to help with mood, but the consumption of antioxidant-rich fruits and vegetables and folate-rich beans and greens may lower the risk for depression.



Improving on the Mediterranean Diet

What are the four problematic nutritional aspects of even plant-based Mediterranean diets?



Why Was Heart Disease Rare in the Mediterranean?

What was it about the diet on the Greek isle of Crete in the 1950s that made it so healthy?

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?



Which Dietary Factors Affect Breast Cancer Most?

American Institute for Cancer Research recommendation compliance associated not only with cancer prevention and survival but less heart and respiratory disease mortality and a longer lifespan.



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.



Second Strategy to Cooking Broccoli

Adding myrosinase enzymes in the form of even a pinch of mustard powder to cooked cruciferous (cabbage-family) vegetables like kale, collards or Brussels sprouts can offer anti-cancer sulforaphane levels comparable to raw, removing the necessity to pre-chop for maximum health benefits.



Anticancer Potential of Sweet Potato Proteins

Sweet potatoes are not just one of the healthiest and cheapest sources of nutrition; the predominant protein is a type of protease inhibitor that may have cancer-fighting properties.



Longer Life Within Walking Distance

Researchers find exercise often works just as well as drugs for the treatment of heart disease and stroke, and the prevention of diabetes. Exercise is medicine.



Cancer Risk from French Fries

The association between cancer and the consumption of deep-fried foods may be due to carcinogens formed at high temperatures in animal foods (heterocyclic amines and polycyclic hydrocarbons) and plant foods (acrylamide).



Food Antioxidants and Cancer

Antioxidant intake from foods (not supplements) is associated with lower cancer risk.



Greens vs. Glaucoma

Kale and collard greens contain vision-protecting plant nutrients, such as zeaxanthin, that may significantly lower the risk of glaucoma—a leading cause of blindness.



Cavities and Coronaries: Our Choice

Coronary heart disease, our #1 cause of death, was found to be almost non-existent in a population eating a diet centered around whole plant foods.



The Broccoli Receptor: Our First Line of Defense

There is a receptor in our intestines activated by phytonutrients in cruciferous vegetables that boosts immune function (the aryl hydrocarbon [Ah] receptor).



Nutrient-Dense Approach to Weight Management

Americans eating meat-free diets average higher intakes of nearly every nutrient, while maintaining a lower body weight—perhaps due, in part, to their higher resting metabolic rates.



Enhanced Athletic Recovery without Undermining Adaptation

Might the antioxidant and anti-inflammatory properties of plant-based diets undermine some of the benefits of exercise?



Testing Your Diet with Pee and Purple Cabbage

Plant-based diets tend to be alkaline-forming. This may help protect muscle mass, and reduce the risk of gout and kidney stones. The pH of one’s urine can be estimated with natural pigments, using kitchen chemistry.



Tricks to Get Kids to Eat Healthier at Home

Tips like cutting vegetables into shapes, covertly puréeing greens into sauces, and modeling healthy behaviors can improve our children’s diets.
