We had a request here at PositiveMed to inform about this particular diet, so here it is:
The Blood Type Diet is a nutritional diet advocated by Peter D’Adamo, the premise of this diet being that your blood type determines the food and exercise you need to be healthy. Food is divided into 3 categories 1)Highly beneficial 2)Neutral and 3)Avoid. Type 1 foods work as medicine, Type 2 work as food, and Type 3 are toxic to that person.
The blood types O, A, B, and AB determine your diet and exercise personality according to D’Adamo, Type O is the hunter, you should have vigorous exercise and a high protein diet. Type A is the agrarian, which is a more vegetarian diet with gentle exercise. Type B is the nomad, the only type that can eat dairy, should have moderate exercise. Type AB is the enigma, mixture of A and B with calming exercise.
Dr. D’Adamo works out of the Center of Excellence in Generative Medicine at the University of Bridgeport in Connecticut. He has written several books and teaches classes out of the Center, called COE, he is an expert at naturopathic and integrative medicine.
The problem with this diet program, according to many experts, is that there is no scientific evidence to support these claims, many of the claims he has made for many years state studies in progress but these studies have not been published and others are unable to duplicate results. David W. Grotto, RD, LD, stated the beliefs are “very obscure and lacking in science.” Most reputable physicians and dietitians do not advocate any diet plan which leaves out any of the food groups, proper nutrition requires a balance of many nutrients.
