Review of Studies Confirms Plant-Based Diets Improve Cardiovascular Health

Plant-based diets improve markers of cardiovascular health among people at highest risk of developing heart disease, according to a meta-analysis published in JAMA Network Open. A comprehensive review of 29 randomized control trials found that cholesterol, blood sugar, and body weight all improved more on vegetarian/vegan diets than they did simply by using standard therapy for cardiovascular disease.1  

Numerous Physicians Committee studies were included in the analysis, including a recent study that found a low-fat vegan diet outperformed a Mediterranean diet in improving multiple cardiometabolic risk factors.2
