Blood group tests are available, which some professionals believe can give you an indication of which foods suit your genetic makeup; more simply, you can just ask your doctor what blood type you are and then follow the general advice below.
Blood types can be broken down into group O, group A (which further differentiates into A1 and A2), group B, and group AB.
diet for blood group o
Historically, the blood group O diet was apparently the first to evolve and is associated with hunter-gatherer societies. People who are Group O do well on diets that are high in proteins such as meat, poultry, and fish.
Dairy products, corn, and most grains should be eliminated. Group O individuals are generally associated with higher levels of hydrochloric acid in the stomach, which helps to digest the higher amounts of proteins found with this type of diet. Fruits and vegetables should also be eaten in larger amounts to help balance the body’s pH level.
diet for blood group a
Historically, blood group A individuals have adapted well to an agrarian form of the diet, which evolved later and consists primarily of fruits, vegetables, nuts, and grains. Generally, little or no meat should be allowed, and then only as a condiment. Milk and cheese should also be eliminated, especially in type A2 individuals. Grains and beans contain higher amounts of naturally occurring agglutinins (lectins), which makes their assimilation by the body more difficult. Larger amounts of fruits and vegetables are recommended for group A individuals, who tend to secrete lower amounts of hydrochloric acid and thus metabolize calories and obtain energy at a slower rate. Raw fruits and vegetables are higher in natural enzymes, which promote digestion, absorption, and assimilation. diet for blood group b Apparently, the blood group B diet evolved later than that of group O or A and is associated with nomadic and herding societies. People who are group B do well with diets that are high in fermented dairy products.
These individuals do better on ovo-lacto vegetarian diets, which are higher in products that contain milk, cheese, and eggs. Natural agglutinins in such foods as chicken, sunflower, sesame, and buckwheat may cause problems for a group B person and should be used in moderation. Group B individuals are generally associated with lower levels of hydrochloric acid in the stomach and may need enzyme and hydrochloric acid assistance if higher amounts of proteins are ingested.
Group B persons do well with a good balance of the different food groups allowed rather than an emphasis on a particular food type.
diet for blood group ab
Apparently, the blood group AB diet evolved last, and it is felt to be associated with modern diets. Because of the presence of both A and B antigens, group AB individuals are well adapted to vegetarian, grain, and seafood diets with small to moderate amounts of milk products. Natural agglutinins in such foods as red meat, chicken, potatoes, tomatoes, and many grains and beans may cause problems for a group AB person and should be used only in moderation. Group AB individuals are generally associated with lower levels of hydrochloric acid in the stomach and may need enzyme and hydrochloric acid supplementation if higher amounts of proteins are ingested. Group AB people do well with a good balance of the different food groups allowed rather than emphasis on a particular food type or group.
