The Individual Diet Solution to Staying Healthy, Living Longer and Achieving Your Ideal Weight
Peter J. D’Adamo, N.D.
Overview:
D’Amano, a naturopath, claims that an individual’s blood type should determine what foods to eat and which ones to avoid. He asserts that when a particular blood type consumes “off-limit” foods, the effect is akin to a transfusion of mismatched blood. His theory attempts to tie the evolution of man to changing blood types and diets. Recommended caloric intake varies widely from day to day.
Advantages:
The diet emphasizes lean sources of protein in addition to recommending several servings of fruits and vegetables for all dieters.
Disadvantages:
Current scientific research does not support D’Amano’s claim that blood type determines an individual’s response to certain foods. Further, most critics of this diet cite the lack of a relationship between blood type and disease as well as the false assumptions made about the diet of early man.
One criticism of D’Adamo’s hypotheses and recommendations claims that he provided inadequate evidence. For example, his first book, Eat Right 4 Your Type, published in 1997, contains only a single reference.
Another criticism is that even though D’Adamo claims there are many ABO specific lectins in foods, this does not agree with what is found in the scientific literature. In research done by separate and independent groups of biochemists, on lectins in different foods and their reactions with ABO blood type, it was shown that there were no differences in how lectins react with human ABO blood type.
Long-Term Success:
Recommended menus include unusual and hard-to-find foods, and hopefully everyone in your family has the same blood type or meal preparation could prove challenging over the long term.
