Blood Type AB


According to Dr. Peter DÁdamo, author of Eat Right For Your Type, a chemical reaction occurs between your blood and the foods you eat. This reaction is part of your genetic inheritance. This reaction is caused by a factor called Lectins. Lectins, abundant and diverse proteins found in foods, have agglutinating properties that affect your blood. So when you eat a food containing protein lectins that are incompatible with your blood type antigen, the lectins target an organ or bodily system and begin to agglutinate blood cells in that area. Different lectins target different organs and body system.

Fortunately, most lectins found in the diet are not quite so life threatening, although they can cause a variety of other problems, especially if they are specific to a particular blood type. For the most part your immune systems protect you from lectins. Ninety-five percent of the lectins you absorb from your typical diets are sloughed off by the body. But at least five percent of the lectins you eat are filtered into the bloodstream and different reactions in different organs.

Your blood type diet is the restoration of your natural genetic rhythm. Your blood type diet works because you are able to follow a clear, logical, scientifically researched plan based on your cellular profile. Each food groups are divided into three categories: Highly beneficial ( food that acts like Medicine), Foods allowed (food that are no harm to the blood type) and Foods not allowed (food that acts like a Poison)

Multiple antigens make Type ABs sometimes A-like with weak stomach acid, and sometimes B-like with genetically programmed for the consumption of meats. Type AB do best when their muscle tissues are slightly alkaline. Type ABs can't metabolize meat efficientlybecause of low stomach acid, so it is important to watch the portion size and frequency. Chicken has lectin that irritates the blood and digestive tracts of Type ABs also. Tofu is a good protein supplements for Type ABs. Nuts, seeds, beans and legumes present a mixed picture for Type ABs. Eat nuts and seeds in small amounts and with caution.

Type ABs can tolerate dairy foods fairly well. But watch out for excessive mucus production.

Generally Type ABs do well on grains, even wheat, but keep in mind that the inner kernel of the wheat grain is highly acid forming in the muscle for Type ABs. Type AB benefits from a diet rich in rice rather than pasta.

Type ABs has a weaker immune system, so you will benefit from the vegetables, which are high in phytocheicals and the more alkaline fruits, which can help to balance the grains that are acid forming in the muscle tissues. Tomatoes do not impose any ill effects on Type ABs.

Type AB should begin each day by drinking a glass of warm water with the freshly squeezed juice of half a lemon to cleanse the system of mucus accumulated while sleeping.

Characteristics of Type AB - Best on Mixed Diet in moderation


Most Beneficial

Food allowed

Food not allowed

Meat and Poultry

Type AB do not produce enough stomach acid to effectively digest too much animal protein. So the key is portion size and frequency.

Lamb, mutton, rabbit, turkey

All kinds except those listed not allowed

Beef, Chicken, Cornish Hens, Duck, Goose, Pork, Patridge, Veal, Venison, Quail

Cured meats can cause stomach cancer Type ABs with low levels of stomach acid


If you have family history of breast cancer, introduce snails (Helix pomatia) into your diet

Cultured and soured products are easily digested for Type ABs

Yogurt, Kefir, Non-fat sour cream, egg, Mozzarella, Goat cheese and milk, Ricotta

All kinds except those listed not allowed

American Cheese, Blue cheese, Brie, Buttermilk, Camembert, Ice cream, Parmesan, Provolone, Sherbet, Whole Milk


Use sparingly


Oil (Corn, Cottonseed, Safflower, Sesame, Sunflower)


Powerful immune booster for Type A and Type AB

Peanut, Walnuts

Type Abs tend to suffer from gallbladder problems, so nut butters are preferable to whole nuts. Also eat small amounts with caution.

All kinds except those listed not allowed

Filberts, Poppy seeds, Pumpkin seeds, Sesame seeds, Sunflower seeds


These beans are important cancer-fighting food for Type AB. They are known to contain cancer-fighting antioxidants.


These beans slow insulin production in Type AB.

Kidney beans, Lima Beans

Beans (navy, pinto)

All kinds except those listed not allowed

Beans (Aduke, Azuki, Black, Fava, Garbanzo) Black-eyed Peas


The inner kernel of the wheat grain is highly acid forming for Type AB. Wheat is not adviced if Type AB is trying to lose weight. The inner kernel of wheat grain is alkaline in Type Os and Bs, it becomes acidic in Type As and AB.

Millet, Oat bran, Oatmeal, Rice Bran, Puffed rice, Rye, Speltand sprouted wheat and any products such as flour, bread and noodles made with these grain products

All kinds except those listed not allowed

Buckwheat, Corn (any products such as flour, bread and noodles made with these ), Kamut, Kasha, soba noodles, Artichoke pasta

Type AB benefits from a diet rich in rice rather than pasta

All kinds of Rice and any products such as flour, bread and noodles made with these


Fresh vegetables are an important source of phytochemicals which have a tonic effect in cancer and heart disease prevention, these diseases afflict Type AB more often as a result of weaker immune system.

Broccoli, Beets, Cauliflower, Celery, Green Leafy Vegs, Cucumber, Eggplant, Garlic, Maitake Mushroom, Parsley, Parsnips, Sweet potatoes, Alfalfa Sprouts, Tempeh, Tofu, All types of Yams

All kinds except those listed not allowed

Artichoke, Avocado, All thype of Corns, Lima Beans, Black Olives, All kind of Bell Peppers, Radishes, Mung Bean Sprouts, Radish Sprouts


Emphasize the more alkaline fruits to balance the grains that are acid forming in Type AB muscle tissues

All kinds of Grapes and Plums, Berries (cranberries, Gooseberries, Loganberries), Cherries

Tropical fruits doesn't agree with Type AB. But pineapple is an excellent digestive aid for Type AB.


Mangoes, Guava, Coconuts, Bananas

Oranges are stomach irritant for Type AB, they also interfere with th absorption of important minerals. But Grapefurit exhibit alkaline tendencies after digestion. And lemons aid digestion and clearing mucus from the system.

Grapefruits, Lemons


Vitamin C-rich fruits help preven stomach cancer because of the antioxidant properties of vitamin cup


All kinds except those listed not allowed


Sea salt and kelp should be used in place of salt. Kelp has immensely positive heart and immune system benefits

The ingredients are acidic

Vinegar, Pepper (white, black, cayenne, red flakes)

Garlic, Horseradish, Parsley


Type AB employed these herbal teas to rev up the immune system.
