The blood type diet is based on the theory that your blood type regulates what are the kinds of food that you should consume to attain optimum health, promote weight loss and fight disease. Peter D’Adamo, a Naturopathic doctor formulated the blood type diet based on how an individual’s body responds to different kinds of food depending on their blood type.
The theory behind this diet is eating foods with lectins (any of a class of proteins, chiefly of plant origin) that are discordant with a person’s blood type that causes agglutination (blood cell dumping) and results in ailments such as heart or kidney or cancer. It also affects a person’s capability to digest different foods due to the changes in digestive secretions linked with different blood types. For example, blood type O, finds it easy to digest meat well due to high levels of stomach acid.
Principles of the blood type diet:
People with blood type A should stick mainly to a vegetarian diet with high intake of fruits, vegetables, grains, beans, legumes, nuts, seeds and avoid dairy products. Do yoga and meditation to lower stress levels.
People with blood type B should stick to a highly diverse diet (including fruits, vegetables, grains, beans, legumes, meat, poultry, fish, eggs, dairy) and stay away from nuts and seeds. Cycling, tennis, hoke and golf are some activities that they can choose to stay physically and mentally strong and active.
People with blood type AB can take any food allowed for blood types A and B. However, a pure vegan diet is recommended. A combination of activities that include meditation and intense exercises like running, aerobics and weight training to stay physically fit is suggested.
People with blood type O should take a diet high in meat content, low in grains, and with a minimal amount of vegetables, eggs, nuts and seeds; at the same time avoid dairy products. Go for exercises that works your cardiovascular and muscular system, like running, Zumba and more to stay fit.
The blood type diet highlights whole foods and minimizes intake of processed foods.
