Blood groups and diet – part 7

The AB group is still today the rarest. It is the last transformation of human blood and, rather than from an evolutionary need, originated about 1,000 years ago in the Caucasus area from the mixture between nomadic populations, mainly of group B, and non-permanent populations, mainly of group A.

The AB group is a mixture between the two groups “parents” and this legacy can be in some cases a strong point and in others a great limit. It has both antigens A and B and therefore cannot develop antibodies A or B: this protects it from autoimmune diseases because the immune system is not induced to attack parts of its own body.

The disadvantage is the tendency not to activate even in the presence of mutant cells in one’s system, exposing oneself more to tumors. Its immune characteristics protected it during the great medieval epidemics, such as typhus and plague. Instead it is more subject to bacterial infections of the respiratory tract, Candida infections and intestinal parasites, while it is well protected from cold viruses.
It has a rather sensitive digestive system, able to tolerate only the foods that are advantageous for both groups A and B, with due exceptions such as tomatoes and wheat lectins which, in excessive doses, can cause weight gain.

From the point of view of sporting activity, the members of this group are the ones who best reflect the characteristics of the modern era: sport is not fundamental but nevertheless advantageous and therefore they should prefer relaxing activities such as swimming, golf, yoga and long walks.

The AB group is relatively young, rare and even biologically complex. It appeared less than a thousand years ago and is owned only by 2-5 percent of the population. In principle, most of the foods harmful to group A or B are also harmful to the AB group with some exceptions.

Weight loss

The simultaneous presence of the two antigens A and B creates some problems. The genetic predisposition to consume meat (characteristic of group B), remains unsatisfied in the AB group since the cells of its stomach secrete, as in group A, scarce amounts of hydrochloric acid and hormones connected to it: a condition that makes it difficult meat digestion. For a weight reduction, the AB group must therefore drastically reduce the consumption of meat. The consumption of Spanish and Lima beans, maize, buckwheat or sesame seeds must also be avoided, as in group B, as they limit the efficiency of insulin activity in favor of carbohydrate metabolism. Although the AB group tolerates wheat-based foods well, it must however limit its consumption because it would make its muscle tissue too acidic, while the AB group metabolism is more efficient under alkaline conditions.

Promote weight gain

  • Red meat, Spanish beans, maize, buckwheat because their fats are poorly metabolized by altering the flora of the intestinal tract.
  • Beans because they limit the efficiency of insulin activity for carbohydrate metabolism.
  • Wheat because they limit the efficiency of insulin activity and muscle alkalinity.

Promote weight loss

  • Fish activates the metabolism.
  • Milk and cheese because they improve insulin production.
  • Green leafy vegetables because they activate the metabolism.
  • Pineapple because it stimulates intestinal motility.

Particular foods and group AB

Meat and poultry
The low gastric acidity does not allow it to be digested well, unless it is reduced in quantity and infrequently. However, lamb and turkey meat are preferred.

Fish and shellfish
They are an excellent source of protein for the AB group. Only anchovies, eel, prawns, oysters, octopus, sea bass, smoked salmon, clams should be avoided.

Milk, dairy products and eggs
In this case, component B takes on a dominant role in relation to A. Green light therefore for yogurt and low-fat cheeses. Component A, however, tends to produce an excess of mucus responsible for respiratory disorders, sinusitis and otitis. In the presence of these problems and in hypercholesterolemia, reduce the consumption of aged dairy products, butter and eggs.

Oils and fats
The AB group must favor olive oil for the presence of monounsaturated fats, corn oil, rich in polyunsaturated fats, only raw; peanut oil, rich in saturated fats that promote cholesterol levels in the blood, only in frying.

Dried fruit
To limit consumption because it contains lectins able to reduce insulin activity and therefore carbohydrate metabolism in the AB group.

Legumes
Only Spanish and Lima beans, chickpeas, green beans with eyes and broad beans should be avoided.

Cereals
The AB group tolerates cereals well. Wheat is unique in that it can cause problems with excess mucus, especially in people with problems with the respiratory tract, sinuses and ear. It is good, however, that the AB group limits pasta consumption to once or twice a week.

Vegetables
Fresh vegetables are, for the AB group, even essential because they reduce the cardiovascular risk to which it is subjected. It is good to take them several times a day. Even tomatoes, poorly tolerated in A or B, do not create problems. Some problems with artichokes, corn, peppers, black olives, radishes.

Fresh fruit
The AB type must favor the most alkaline fruits such as grapes, prunes and berries. To avoid the oranges because irritating the stomach and therefore able to interfere with the absorption of some essential minerals. Grapefruit and lemon, on the other hand, at the time of digestion develop a certain degree of alkalinity and therefore can be taken without problems. The banana produces absorption problems in the AB group; in its place, for a good source of potassium, apricots, figs and melon are to be consumed.

Juices and drinks
The AB group should start the day by drinking a glass of water flavored with the juice of half a lemon, to eliminate excess mucus. Other preferred drinks are carrot, cherry, blueberry, grape and papaya juice.

The spices
The AB group must limit the intake of sodium salt and vinegar; avoid pepper, garlic, curry, parsley.

Preserves and sauces
Avoid all pickled and pickled foods as well as ketchup containing vinegar.

Infusions and drinks
The AB group must stimulate its too lazy immune system even with infusions of alpha alfa, burdock, hawthorn, chamomile, echinacea, and dog rose. Excellent red wine for its activity on the arteries that can reduce the cardiovascular risk; also one or two cups of coffee because it increases acidity and therefore gastric digestion and contains the same enzymes present in soy. To obtain maximum benefits, it is advisable to alternate coffee and green tea regularly.

This concludes our mini series regarding the blood groups types and the best suited diets for them. I would like to thank all of you who have participated with comments and helped to shine even more light into this broad topic. If you liked this series and would love to read more of this kind of “series” you are welcome to leave your comment, we will take it in consideration for future posts.

    As a result, the subject with blood group AB can, being free of specific antibodies, receive blood from both donors of type A, B, AB and 0

    the AB group contains antigens A, antigens B and none of the corresponding plasma antibodies

    AB gropup is an universal receiver, while those who have blood group 0 can receive only from donors with group 0 but, at the same time, they are able to donate blood to anyone (universal donor).

    The AB blood group is the rarest in Europe and beyond: according to the Stanford School of Medicine, only 0.6 percent of the world population has a type AB blood type negative.

    The concept of “blood type” is not entirely meaningless to our health. In particular, various studies show that the type of blood group can be a risk factor for some diseases.

    I binge read all this series with interest. By far my favorite. It would be with joy that I would read more of this series type of article. Thanks for all your good advice.

    All good but…Ultimately, studies are needed to investigate the possible correlation between blood group and health because nothing certain is known about this topic.

    @Nicole Bryan I thought I had read something similar and then read your comment. Yes Peter D’Adamo is the “founder” of this so called “blood type” diet.

    According to Peter D’Adamo, in some foods there are particular proteins, lectins, which can influence the various blood groups in different ways. However, the “blood group diet” has no scientific assumption: according to various studies, the various types of lectins are contained simultaneously in the vast majority of foods and therefore would not be able to selectively attack only one blood group.
