This is the first time I’ve heard about this, but it makes sense!

Scientific Explanation for Food Recommendations Based on Blood Type

There is still a debate among scientists about the scientific foundation of the Blood Type Diet. Dr. D’Adamo says that the various substances in each blood type interact differently with certain nutrients. This means that some foods can be good or bad for a person depending on their blood type. Lectins are proteins in food that attach to antigens in blood types, impacting digestion and health. However, there is not enough solid scientific proof to support these statements, and many researchers doubt this theory.

Foods for Blood Type A: What to Eat and What to Avoid
People with blood type A are thought to do well on a diet that does not include meat. Foods that are good for this blood type are vegetables, fruits, tofu, seafood, grains, beans, legumes, and just a little dairy. Foods to avoid are meat, especially red meat, dairy, kidney beans, lima beans, and some wheat products. The theory proposes that people with type A personality have a more delicate immune system and less stomach acid, which makes it easier for them to digest and process plant-based foods.

Foods for Blood Type B: What to Eat and What to Avoid

People with blood type B are believed to have a well-rounded immune system and can eat a variety of foods. It is suggested to eat green veggies, eggs, meats such as lamb and goat, low-fat dairy products, and certain grains. Foods you should stay away from include chicken, corn, wheat, lentils, peanuts, and tomatoes. The diet recommends that people with type B blood should eat foods that improve metabolism and keep their gut healthy.

Foods for Blood Type AB: What to Eat and What to Avoid

People with blood type AB should follow a diet that includes recommendations from both type A and type B diets because they have both A and B antigens. Foods that are good to eat are tofu, seafood, dairy products, green veggies, and grains such as quinoa and brown rice. Foods to avoid include chicken, corn, buckwheat, and kidney beans. This diet focuses on foods that help the immune system and digestion, which are important for people with both A and B antigens.
