From March 13, 2002: Physician, researcher and author of the New York Times best-selling book Reversing Heart Disease, Dr. Dean Ornish advises women on how to prevent and reverse heart disease through diet and lifestyle. He discusses the importance of knowing your cholesterol level, the physical effect of toxic emotions and how just one minute a day of meditation can improve your health. Dr. Ornish also highlights three categories of food—the foods to eat most often, those to eat in moderation and those to eat least often.
