They may seem a little faddish sounding, but Joel Fuhrman has several books written for a popular audience on dietary interventions for a variety of health conditions, diabetes and heart disease among them. Eat for Life was his first book, and then he wrote The End of Diabetes. Both books lay out a fairly restrictive diet plan for improving health. His patients come of medications quite quickly and he provides anecdotal stories of several patients who have had long term conditions that were able to reverse the problems through diet.
