These medical doctors have been at the forefront of advocating a plant-based, whole foods, vegan diet to prevent and reduce cardiovascular disease, stroke, cancer, and other chronic diseases, while promoting optimal overall health and longevity. These world-renown physicians have individually conducted numerous medical and scientific research studies on the role of nutrition and diet on health; authored ground-breaking research papers and articles published in prestigious medical, scientific and nutrition journals; led national and international expert committees on nutrition and health; authored multiple books and produced TV series; launched non-profit organizations and led pioneering renown nutrition programs; and opened health and medical clinics — to promote the benefits of a plant-based, whole foods diet.

This list of doctors is not conclusive, but represents some of the leading internationally-recognized experts in the field today.
