Doctors Discuss Diet, Nutrition, and Heart Disease


These doctors add an interesting perspective to the diet and health debate. Drs. Ornish and Esselstyn specialize in treatment and diet-related issues in regard to reversing heart disease. I have found these doctors to be thoughtful and passionate. 

Of course, if you have any type of heart disease or any other health issue, you must consult with your own physicians. It is important to note: This information is not meant, in any way, to replace your own medical professionals.
