Dr. Peter J. D'Adamo created the Blood Type Diet. D'Adamo believes that your diet should be dictated by your blood type. For example, people with type A blood do well on a vegetarian diet, while those with type O should concentrate on eating seafood and organic meats and avoid wheat and dairy. Type AB people should eat a diet that combines A and B blood-type diets. Both AB positive and AB negative individuals should eat the same food.
Proteins
According to Edwards Drugs Wellness Center, the best proteins for AB type are seafood, non-fat or low-fat dairy, tofu and lentils. Avoid beef, chicken and pork and instead eat more lamb and turkey. Soft cheeses, like cottage cheese and feta, are best for AB types. Also try goat cheese. While most beans are acceptable or neutral sources of protein for AB types, the best options are navy, pinto and red beans.
Whole Grains
Type AB should avoid sweets and white flour and instead focus on whole grains only. Millet, oatmeal, brown rice, puffed rice cereal, oat bran and rye are the best choices. Avoid buckwheat and corn. Other grains and cereals, like granola, barley and pumpernickel, are considered neutral, which means they can be consumed in moderation and only when the best choices are not available.
Vegetables
D'Adamo recommends that type AB focus on green vegetables. Examples of appropriate choices include broccoli, kale, mustard greens, sprouts, collard greens, celery, cucumber and parsnip. Other acceptable vegetables include beets, cauliflower, yams and garlic.
