Also called the biotype diet, the Blood Type diet was designed by author Dr. Peter D’Adamo, who outlined the program in his book "Eat Right for Your Type." On the plan, dieters eat certain foods deemed beneficial for their particular blood type. According to D’Adamo, food proteins called lectins are digested differently depending if you are a Blood Type A, B, AB or O. The B Blood Type person has more flexibility in her diet compared to O and A, but does best on a gluten-free diet.
Some of the sweeteners on the beneficial list for Blood Type B people include black strap molasses and real maple syrup. Honey is considered neutral, which means it’s not harmful, but doesn’t have any special nutritional properties that benefit Blood Type B. The natural sweetener stevia, as well as artificial sweeteners, should be avoided.
The Type B Blood Type should avoid chicken, bacon and shrimp. Beef, eggs and turkey are neutral sources of protein. Highly beneficial protein sources include wild salmon, lamb, goat, mutton, rabbit, venison and sardines. Most beans should be eliminated, although kidney and navy beans are acceptable.
Type B Blood Types typically have lactose intolerance. They may have some low-fat and milder dairy including mozzarella cheese and goat cheese. Kefir and yogurt, which both contain probiotics, are also beneficial to digestion for the B Blood Type. Feta cheese and rice milk are also on the approved list for Blood Type B.
Blood Type B dieters have the most weight gain issues with corn, wheat and buckwheat. They are allowed to eat rice, which is a neutral food for them. Highly beneficial flours or gains include oat flour and spelt. They should avoid buckwheat soba noodles.
Fruits and Vegetables
Dieters with a Blood Type B should avoid tomatoes and stick to a lot of green vegetables. The Blood Type B beneficial fruits include pineapple, watermelon and bananas. Approved beneficial vegetables include carrots, sweet potatoes, broccoli, Brussels sprouts, onions and lima beans. These fruits and vegetables are believed to help the body resist diseases.
Oils and Spices
Olive oil and flaxseed oil can be included in the Blood Type B diet. Most spices have a neutral effect on Blood Type B, although pepper and cinnamon should be avoided. They should also avoid sesame, corn and sunflower oils. Curry and parsley are considered beneficial and can be eaten frequently on the Blood Type Diet.
