B is for blood type. There are four basic blood types – O, A, B, and AB. These are determined by chemical markers called antigens. Antigens are in every cell of the body and are a key part of the immune system. When your immune system senses a foreign element, it looks to the blood type antigen to determine if the element is good or bad.
Because each blood type has its specific set of antigens, each of has different immune responses to chemicals in our bloodstream. One important source of chemicals in our blood stream comes from the food that we eat. Every food has specific lectins or proteins that interact with our cells and our immune system. When the interaction is negative, all cellular functions are interrupted. These include you digestion, metabolism and immune system.
By avoiding the negative foods for your blood type, you reduce stress on your digestive tract and immune system, freeing up vital energy that can now manifest as health, vitality and energy. Foods that are beneficial to your blood type tend to strengthen and heal your body, while foods that are negative to you will tend to act like a poison.
Each blood type carries certain characteristics – both in personality and in physical nature.
Type O is the hunter-gatherer type who does well on meat and vegetables. O’s tend to self-reliant leaders with strong digestive systems. O’s are prone to inflammatory diseases, ulcers, allergies and blood clotting disorders. Type O’s should avoid milk, wheat (both white flour and whole wheat products), white potatoes, peanuts and citrus fruits such as orange and tangerine.
Type A stands for agrarian. They tend to be adaptable, sensitive, creative and can be prone to anxiety. A’s can also have sensitive digestive tracts. They are prone to high cholesterol, heart disease, liver and gallbladder disorders and diabetes. Type A’s do well on light meats such as chicken and fish, soy, fruit and nuts. Type A’s should limit red meat, pork, milk, wheat and oranges. Type A blood types tend to not make enough stomach acid to digest heavy meat. If you are an A and insist on eating lots of red meat, consider adding a digestive enzyme containing betaine.
Type B’s are the most balanced blood type. They tend to have strong immune systems, although when out of balance, B’s are prone to auto-immune problems such as diabetes, rheumatoid arthritis, lupus, etc.. B’s do well on fish, turkey, dairy, potatoes, and vegetables. They should avoid pork, chicken, tomatoes, peanuts, shellfish and wheat.
Type AB is a hybrid with some of the characteristics of both A and B. AB’s tend to be loyal and reserved. Type AB has an immune system that tends to be over-tolerant resulting in proneness to infections, allergies, and parasites. AB’s do well on fish, turkey, eggs, cultured dairy, beans and spelt. Type AB is the only blood type that handles tomatoes well. AB’s should avoid chicken, pork, corn, wheat, and bananas.
