Cook Right 4 Your Type:
The Practical Kitchen Companion to "Eat Right 4 Your Type"
Today we are talking about the Blood Type Diet. Actually, four diets for four Blood Types. The author is Peter D'Adamo and he seems to reveal the connection between blood type, diet, and health. If you know your blood type (most of us do), then all you have to do is to open your blood type chart and see what you can eat, what you can't and all in between. There's also 30-day meal plans and more than 200 recipes for every type.
Peter D'Adamo graduated from Bastyr University with an ND degree. He is now in private practice in Connecticut as a physician and lecturer. The "Eat Right" book is based upon years 35 years of research by his father, James D'Adamo, a naturopathic physician, and later on his own theory and observations.
Alternative Medicine Review Vol. 2 No. 2 Review by Greg Kelly, ND:
The premise of the book is that if you use your blood type as a guide for eating and living, you will be healthier, you will reach your ideal body weight, and you will slow the aging process. Because blood types historically evolved due to changes in diet, culture, and social conditions, each blood type has particular strengths and limitations. When these are known and followed, it becomes easier to maintain health.Review in the Townsend Letter For Doctors, review by Jule Klotter:
Each of the four blood types, which develop at separate times in human evolution, exhibit biochemical differences. Type O, the oldest and most common blood type, has no true antigens (chemical markers that incite antibody production). Because of this, type O, also called "the universal donor," does not cause antibody production when given to people with other blood types. The next oldest, Type A, first appeared in Asia or the Middle East between 25,000 and 15,000 BC as an evolutionary response to the rise of densely populated agrarian communities. The Type A antigen causes antibody reactions in Type O and Type B, the third blood type. The Type B antigen appeared between 10,000 and 15,000 BC among nomads in the Himalayan highlands. The most recent and least common, Type AB, has the antigens of Types A and B, combining many of the characteristics of the two. People with AB blood can receive blood from A, B, as well as AB and O donors without experiencing an antibody response.Now, what is known to the medical science?
Not much to tell you the truth. However, these few facts at least can show that something - some vague connections - between body functions relating to digestion on one side, and blood types on the other side, might be existent.
1. The level of LDL, the "bad" cholesterol, can increase in response to a low fat diet. The degree of this adverse effect depends on one's blood type. (Twin study at Queensland Institute of Medical Research, Brisbane, Australia - Clinical Genetics. 51(5):291-5, 1997)
2. There is a certain intestinal enzyme going under the ugly name "high molecular mass intestinal alkaline phosphatase." During fasting, this enzyme works best for blood groups O and B and the lowest activities were associated with blood group A. (Department of Clinical Chemistry, Saitama College of Health, Urawa, Japan - Clinica Chimica Acta. 277(1):13-24, 1998)
3. Depending on one's blood type, there can be higher or lower probability of duodenal ulcer. However, these relations can be masked by food habits, diet, smoking, and family history. (Bangladesh Medical Research Council Bulletin. 12(1):32-6, 1986).
4. Certain types of sugars in the blood are blood type dependent: the "blood group A trisaccharide" (Clinica Chimica Acta. 114(1):11-9, 1981) and "blood-group-active oligosaccharides" (European Journal of Biochemistry. 100(2):385-92, 1979), all having different reactions to oral intake of galactose (a free sugar), lactose, and sucrose.
5 The concentrations of so called gut-brain regulatory peptide gastrin during fasting and after meals were different depending on blood type (Acta Hepato-Gastroenterologica. 25(6):482-6, 1978).
That's it! At least this is all I've managed to find in the most professional medical database Ovid. Why the "Blood Type Diet" is reportedly so successful? Have any ideas? Tell me!
