For more than 20 years, heart expert Dr. Dean Ornish has studied how changes in diet and lifestyle can prevent and even reverse coronary heart disease. Now he's faced with the challenge of convincing the medical community, big business and the public at large that his plan really works. Dr. Oz talks with Dr. Ornish about his many initiatives to spread the word about how combining a low-fat, vegetarian diet with exercise and meditation can improve health, prevent chronic illness and still be economically viable.
From his work with global food manufacturers in implementing healthier foods, to gaining support from healthcare providers such as Medicare, Dr. Ornish discusses the ways he's working to affect public policy change and improve the quality of life for Americans today. "These are profoundly human issues, and I think we need to find creative solutions [so] when we work at that level, it's not only medically effective, it's cost effective," Dr. Ornish says.
