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.



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.

Advanced glycation end products in our diet may suppress sirtuin enzyme activity and play a role in age-related brain volume loss.



Flaxseeds for Hypertension

Extraordinary results reported in a rare example of a double-blinded, placebo-controlled, randomized trial of a dietary intervention (flaxseeds) to combat one of our leading killers, high blood pressure.



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?

How do canned versus germinated beans (such as sprouted lentils) compare when it comes to protecting brain cells and destroying melanoma, kidney, and breast cancer cells.



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?



Does Meditation Affect Cellular Aging?

Dr. Dean Ornish showed that his plant-based diet, exercise, and stress management intervention could in effect reverse the aging of our DNA. What effect might the stress management component have had?



Beans, Beans, They’re Good for Your Heart

Legumes such as lentils, chickpeas, beans and split peas may reduce cholesterol so much that consumers may be able to get off their cholesterol-lowering statin drugs, but to profoundly alter heart disease risk we may have to more profoundly alter our diet.

Four simple health behaviors may cut our risk of chronic disease by nearly 80%, potentially dropping our risk of dying equivalent to that of being 14 years younger.



Caloric Restriction vs. Animal-Protein Restriction

The lifespan extension associated with dietary restriction may be due less to a reduction in calories, and more to a reduction in animal protein (particularly the amino acid leucine, which may accelerate aging via the enzyme TOR).
