Dean Ornish, MD

​Dr. Ornish has been conducting research on diet and lifestyle interventions for 35 years. His landmark Lifestyle Heart Trial 

demonstrated that a combination of intensive lifestyle changes including a low-fat plant-based diet could reverse heart disease. Since the Lifestyle Heart Trial he has used these same intensive lifestyle interventions to demonstrate positive outcomes in patients with diabetes, prostate cancer, depression, high cholesterol and high blood pressure.

Caldwell Esselstyn, MD

Similar to Dr. Ornish, Dr. Esselstyn also demonstrated that patients with cardiac disease could reverse the disease by following a plant-based diet with no more than 10% of calories from fat. Unlike Dr. Ornish's study, Dr. Esselstyn's patients were not instructed to make any other lifestyle changes besides diet.

 Neil Barnard, MD

​Dr. Barnard has conducted several studies using a plant-based diet to assess its effect on health. The results of these studies have shown that a low-fat plant-based diet can improve glycemic and lipid control in patients with diabetes, promote wt loss in overweight post menopausal women and reduce menstrual pain in women.

​​T. Colin Campbell, PhD

​​Dr. Campbell has been involved in nutrition research for over 40 years and has authored more than 300 research papers. His 20 year collaboration with Cornell University, Oxford University and The Chinese Academy of Preventive Medicine known as the China Project or China Study produced over 8,000 statistically significant associations between diet and disease. 

The China Study produced over 50 peer reviewed publications and details of the study can be found in T. Colin Campbell's book The China Study. The study found that plant-based diets were associated with less diseases such as heart disease, cancer and diabetes and that people who ate the most animal-based foods got the most chronic diseases.

The China Study did not prove that plant-based diets protect from disease but it added a great deal of weight to other mounting evidence that a dietary pattern consisting mostly of plant foods is beneficial.
