Introduced by Peter D'Adamo, the Blood Type Diet is based on the assumption that everyone is an individual. And who are we to argue? Logically, just because we share the same row and column in the BMI chart, it shouldn't define the way our dietary habits are. The Blood Type Diet makes interesting claims that people fare better (which includes weight management) when their diet is tailored to their specific blood type.
Individuals who fall under the Type A blood group should basically stick to fruits and vegetable. Their blood types is generally thicker than other blood types, and possess a sensitive immune system. These individuals should not consume (or should reduce intake) dairy products, animal fats and meats. They are also at a heightened risk for cardiovascular disease, diabetes and cancer.
Type B blood groupers should consumer a balanced diet of fruits and vegetables, grains, dairy and meat. However, they should try to refrain from chicken, and increase intake of red meat such as duck and beef. Unlike the other blood types, Type B individuals have the best chance of bypassing or overcoming everyday types of diseases, as well as heart disease and cancer.
For Type AB individuals, intake of a mostly vegetarian diet is recommended. And only on rare occasions should they indulge in some fish, meat (not chicken) and dairy.
Those that fall under the Type O blood type should basically stick to a high protein diet, low carbs, as well as a balanced intake of fruits and vegetables. However, food foes for Type Os include most grain food such as corn and wheat germ. They should also try to avoid dairy products. Type O types are commonly affected with hypothyroidism, high stomach acid (leading to ulcers), and thinner blood with greater resistance to blood clotting.
