A physician and nutrition expert who teaches better health through vegetarian cuisine, John A. McDougall, MD has been studying, writing, and speaking out about the effects of nutrition on disease for over 50 years. Dr. John and Mary McDougall believe that people should look and feel great for a lifetime. Unfortunately, many people unknowingly compromise their health through poor dietary habits.

T. Colin Campbell, PhD has been dedicated to the science of human health for more than 60 years. His primary focus is on the association between diet and disease, particularly cancer. Although largely known for the China Study--one of the most comprehensive studies of health and nutrition ever conducted, and recognized by The New York Times as the “Grand Prix of epidemiology”--Dr. Campbell’s profound impact also includes extensive involvement in education, public policy, and laboratory research.
