The Blood Type Diet

I first heard about the blood type diet on Facebook. I thought it sounded feasible so did some research.

There are 4 blood types: O, A, B, and AB. If you have ever given blood, have had major surgery, or have served in the military, then you probably know your blood type. There are other distinguishing characteristics of blood including Rh factor and secretor status. Please google them for more info.

Dr. Peter J. D'Adamo

Dr. Peter J. D'Adamo is considered the father of the blood type diet. He has written a best selling book and published a website on the subject.

Peter D'Adamo is a naturopathic physician. He is considered a world expert in glycobiology (the study of the structure, biosynthesis, and biology of saccharides that are widely distributed in nature), principally the ABO (ABH) blood groups and the secretor (FUT2) polymorphisms.

In 1990 Dr. D'Adamo was awarded Physician of the Year by The American Association of Naturopathic Physicians. He is Adjunct Clinical Professor for the Southwest College of Naturopathic Medicine, Tempe AZ, and the National College of Naturopathic Medicine, Portland OR.

According to Dr. D’Adamo and other researchers, blood type is a key genetic factor that influences many areas of health and well-being including metabolism and chances of developing a chronic illness like cancer.

Specific Information on Blood Type Characteristics

People with blood type O have a lower risk for heart disease, but a higher risk for developing stomach ulcers. People who are blood type A have higher risks of microbial infections, but Type A women experience a higher rate of fertility. People with type AB and B blood have a much higher risk of developing pancreatic cancer. Type A people have higher levels of the stress hormone cortisol. People with type O blood have a reaction to stress which results in the overproduction of adrenaline. It takes type O’s longer to recover from stress because it is more difficult for them to clear the adrenaline from their bodies. If you are blood type O or B, the best way you can keep you bones healthy and protect your cardiovascular system is to insure an adequate amount of healthy fats and animal protein in your diet. If you are type A or AB, your digestive strengths lie elsewhere, and you are best served by a plant-based diet.

People of different blood types have different gut bacteria. This goes back to our ancestors whose digestive tracts developed to accommodate one type of diet over another. For example – people with blood type A break down carbohydrates much more efficiently than people with blood type O who tend to store carbs as fat.

Type O-People fare best on intense physical exercise and animal proteins and less well on dairy products and grains, says Dr. D'Adamo. The leading reason for weight gain among Type O's is the gluten found in wheat products and, to a lesser extent, lentils, corn, kidney beans, and cabbage. Ideal exercises for Type O's include aerobics, martial arts, contact sports, and running.

Those with blood type A, however, are more naturally suited to a vegetarian diet and foods that are fresh, pure, and organic. As Type A's are predisposed to heart disease, cancer, and diabetes, "I can't emphasize how critical this dietary adjustment can be to the sensitive immune system of Type A," says Dr. D'Adamo. Type A's can derive significant benefit from calming, centering exercise, such as yoga and tai chi.

Type B's have a robust immune system and a tolerant digestive system and tend to resist many of the severe chronic degenerative illnesses, or at least survive them better than the other blood types. Type B's do best with moderate physical exercise requiring mental balance, such as hiking, cycling, tennis, and swimming.

Blood type AB, the most recent, in terms of evolution, of the four groups and an amalgam of types A and B, is the most biologically complex. For this group, a combination of the exercises for types A and B works best, says Dr. D'Adamo.

We can’t change our blood types, but worrisome statistics can be changed by eating the right foods for each blood type. Everyone does not have the same basic nutritional needs -- a lot depends on blood type. The Blood Type Diet combines anthropology, medical history, and genetics into lifestyle recommendations that brings health and well-being to followers.

When following the Blood Type Diet, improvements such as increased energy, weight loss, a lessening of digestive complaints, and improvement of chronic conditions (such as asthma, headaches, and heartburn) should be noticed within two weeks.
