Naturopath Dr. Peter J. D’Adamo developed the theory that people with different blood types should eat more of certain foods while avoiding others. He believed that this would boost the immune system, help to control weight and the effects of aging, and fight cardiovascular disease, cancer, diabetes, and liver disorders.
Blood Type A
Should stick to a vegetarian diet consisting of fruits, vegetables, and grains. Oats are recommended for those with blood type A. Their main benefit is their high soluble fiber content. Whether it’s in salad, soup, or hummus, beets are recommended. Lentils are rich in protein and minerals, allowing for a balanced diet without eating meat. Cod is high in omega-3 and vitamin B12, which means that those with blood type A should include it in their diet. All types of meat and dairy products should be avoided. Crustaceans should also be avoided, including crabs and prawns.
Blood Type B
Should follow a carnivorous diet. Though often given a bad reputation, red meat does have some good qualities and is recommended for those with blood type B. In particular, it’s rich in vitamins B3, B12, and B6, as well as iron, zinc, creatine, and carnosine. Dairy products contain high levels of calcium, which is ideal. Studies have shown that eggs contain choline, which is essential to developing brain function and memory. Those with blood type B are lucky that they can include them in their diet. They should avoid chicken, turkey, and duck. Soy is a definite no-no.
