He also authored three other books in 1975, '76 and '78 about nutrition. These books might have been in response to the death of his father, from what he grew to believe was a preventable disease. These books suggest we should live by these three principles: Eat no refined sugar, eat no white flour, and do not take vitamin pills or other supplements. The three books are "The Save Your Life Diet", "The Save Your Life Diet High-Fiber Cookbook", and "Everything You Always Wanted to Know About Nutrition". The last book was written in the same style as his famous book "Everything You Always Wanted to Know About Sex".
