Nothing fundamental in human physiology, and certainly nothing
fundamental in the human genome, has changed over just the past
few decades during which epidemic obesity has emerged. Human
physiology is substantially the same as it ever was. - Dr. David L. Katz

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.
