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 fi rst 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 fi sh. Dairy products, corn, and most grains should be eliminated.
Group O food and nutrition 44 food and nutrition 45 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 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 make 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.
