“It's not one set of dietary guidelines for improving your performance as an athlete, another one for reversing heart disease, a different one for reversing diabetes, a different one for reversing prostate cancer. It's the same for all of them.”
— DR. DEAN ORNISH IN THE GAME CHANGERS
A review of multiple major cohort studies published in Nutrients concluded that “Vegetarian diets confer protection against cardiovascular diseases, cardiometabolic risk factors, some cancers and total mortality. Compared to lacto-ovo-vegetarian diets, vegan diets seem to offer additional protection for obesity, hypertension, type-2 diabetes, and cardiovascular mortality.” (27)
Conversely, researchers studying lapsed vegetarians found that those who started eating meat at least once a week experienced more than double the increase in odds of heart disease, stroke, and diabetes, triple the increase for weight gain, and an associated 3.6-year drop in life expectancy (44).
Plant-based diets have also been shown to improve symptoms, often dramatically, for people suffering from numerous inflammatory diseases and conditions, including rheumatoid arthritis (45), multiple sclerosis (46,47), inflammatory bowel diseases (48,49), and asthma (50,51).
There even seems to be emerging evidence that a plant-based diet could also help prevent and/or reduce symptoms of dementia, including Alzheimer’s, for many the most feared disease of all. As a result, the 2014 “Dietary and Lifestyle Guidelines for the Prevention of Alzheimer’s Disease” published in the journal Neurobiology of Aging, recommended that “vegetables, legumes (beans, peas, and lentils), fruits, and whole grains should replace meats and dairy products as primary staples of the diet.” (52,53)
