Scam Alert: Peter D'Adamo's Blood Type Diet

Eat Right For Your Type by Peter J. D’Adamo, N. D.

This book's basic premise is that the ABO blood type is the most important factor in determining a healthy diet. According to his theory, people with Type O are "hunters" and thrive on a meat-rich diet. Type A's should be vegetarians, while Type B's should eat more dairy products.

Without going any further, any medical professional or even a first-year medical student would tell you that this idea is unbelievable. Just as your liver does not control your thoughts and emotions, the blood groups have nothing to do with the metabolism of food. Also, there are people with the B blood type who are lactose-intolerant, and should not consume dairy. Just that alone puts into dispute his entire argument, which is full of loop-holes.

A more thorough critique of the Blood Type Diet is described by Dr. M. Klaper. Read his essay for some excellent arguments disputing this quack theory.
