John A. McDougall, M.D. is a physician on a mission: He believes he can heal a logjam of illnesses by diet alone and that means no meat, dairy, eggs or oil. At first blush, this may seem like a radical idea for those accustomed to the trials of traditional medicine, but McDougall’s work is not speech or a rant. His work is backed up by disinterested scientific studies and his presentation of these facts is stunning. As a Vegan, I found Dr. McDougall’s program appropriate, accessible and helpful.
