“I have no problems with the blood type A recommendations, which is a plant-based diet,” says Grotto. They should avoid caffeine, alcohol, and smoked and cured meats and try to eat more small meals throughout the day.

Type AB People whose blood is type AB should choose tofu, seafood like mahi-mahi and salmon, dairy like yogurt and kefir, and green vegetables like kale and broccoli.They should avoid certain foods - like corn, wheat, buckwheat, lentils, tomatoes, peanuts, sesame seeds, and chicken - and instead opt for goat, lamb, mutton, rabbit, green vegetables, eggs, and low-fat dairy products. Type B People whose blood is type B are identified as omnivores who can eat a variety of foods.They are also encouraged to eat organic and fresh food in as natural a state as possible. Type A People whose blood is type A are steered toward a vegetarian diet, including soy proteins, grains, and vegetables.Reach instead for fruits, vegetables, and lean, organic meats. Type O If you are type O, like an estimated 46 percent of the population, the Eat Right 4 Your Type program suggests that you stay away from wheat, dairy, caffeine, and alcohol.If you’re interested in exploring the eating plan, here’s an outline of what foods you should eat and stay away from, based on each blood type: “To base a whole diet on that is probably not very sensible,” she says. In fact, while people often have different nutritional needs, humans are complex animals, and chalking up these specifics to blood type may oversimplify those needs, Weinandy says. However, the diet is specific about which foods are allowed for different blood types - and that can be restrictive, Weinandy says. In addition, he recommends exercise and overall healthy habits, like drinking enough water, Weinandy explains.

Reducing their potential health harms is relatively easy: For example, lectins found in dried beans can be eliminated simply by soaking the beans in water for a few hours and then boiling them for 10 minutes, Weinandy says.īut D’Adamo uses his theory to develop separate diets for people with blood types A, B, AB, and O. Liz Weinandy, RD, at the Ohio State University Wexner Medical Center in Columbus, Ohio, says that lectins can be dangerous to our health if eaten in large amounts, but the way D’Adamo presents their effects may be misleading. Avoiding agglutination, D’Adamo argues, can improve health by helping people manage weight better and fight cancer and heart disease. D’Adamo says that protein components in food called lectins bind with antigens on blood cells and lead to blood cell clumping, or agglutination.
