The relationship between the blood group and the diet is not absolute, but it is certainly there. The human blood group is one of the biological components of the general characteristics of its body. By obeying the laws of nature, blood groups have not generally changed since the appearance of man. "This is our ancient ancestors signed on the eternal parchment of history" (Peter D. Adamo). The blood group is a clear genetic imprint, indicating heredity and helping to maintain and improve health. With the blood group that determines the evolutionary process of a person, the dietary needs of people are partly related. A specific diet, corresponding to your blood group, provides restoration of the natural genetic rhythm, laid many millennia ago. The complex biochemical reactions between blood and consumed food, the nature of which is part of the genetic heritage, helps the human immune and digestive systems to maintain a predisposition to the products used by its ancestors with the same blood group. If everyone followed his "instructions", that is, his biological nature, sometimes sounding at the subconscious level, he would significantly improve his state of health. The choice of diet for each of us is made many thousands of years ago.
Thirty years of research by a group of American doctors led by Peter D. Adamo confirmed the thesis that there is a direct link between the human immune and digestive systems through blood groups. All this is also connected with the evolutionary process, therefore, the food should correspond to these groups, because the human body is configured for the type of food, which is also determined by its group affiliation.
Blood group 1 (0) is the oldest and most common. People of this group are born "hunters", strong, self-confident. This "meat-eaters" with a physiologically stable digestive tract, an active immune system, but a poor adaptation to the newfangled diets. They need the activation of metabolic processes. Adequate physical activity for them is an effective way to relieve stress. In the basis of nutrition proposed D. Adamo, for people of this group put the use of lean dark meat (beef, lamb), poultry, fish with restriction of dairy products, eggs and cereals. They entered the diet of an ancient person later than the formation of this group of blood - with the emergence of agriculture and cattle. Diseases, which are primarily predisposed to the owner of the blood group 1, - inflammatory, joint, hypothyroidism, blood diseases.
The appearance of II (A) blood group is associated with the formation of agricultural communities. The people of this group are thoughtful, ambitious, and willing to cooperate. They are mostly vegetarians, who have a sensitive digestive tract and a tolerant immune system. They adapt well to changes in the environment and nutritional conditions. First of all, meditation (self-complacency) helps to relieve stress. In nutrition, they need to restrict meat, because, unlike the organism of "hunters", where meat is quickly "burned", in "farmers" it is more transformed into fat, which is associated with the corresponding type of acidity of gastric juice (elevated). Dairy food is digested worse. It is necessary to limit wheat, acidifying blood. Natural products with low fat content, as well as vegetables, vegetable oils and cereals are useful. A good addition are the seeds of pumpkin, sunflower, walnuts. Improve the metabolic processes help seafood, liver, cabbage. Possible diseases - heart, anemia, liver and gall bladder disease, diabetes mellitus.
The great-grandparents of the blood group III (B) were "nomads" whose life was connected with the continuous movement through vast territories with a more severe climate. These are balanced, calm people with an active immune system, a good digestive tract, which allows you to expand the range of used foods, including. milk. Structural work contributes to the protection of stresses. To prevent weight gain, you should limit corn, peanuts. "Nomads" react poorly to gluten, found in food products from wheat and whole grains. Possible diseases are autoimmune, diabetes mellitus.
The blood group IV (AV) is the youngest, it appeared less than a thousand years ago as a result of the confusion of other groups. People with this blood type have a sensitive digestive tract and a labile immune system. The optimal way to maintain active viability is to combine intellectual activity with easy physical labor. To activate metabolic processes, it is necessary to limit meat products, combining them with vegetables ("hide meat in vegetables"), seafood (except canned, dried and smoked).
Therefore, when determining the dietary regimen, the diet should be based on the individual characteristics of your body, incl. and blood group. Scientists, examining the relationship between the nature of nutrition and blood groups, studied the effect of many food products on the level of hemoglobin in humans. It turned out that extracts from unwanted foods agglutinated (glued) blood cells in certain groups due to the protein agglutinogens found in food (lectins - phytohemoagglutinins). By their characteristics, a number of food lectins are close enough to antigens of one blood group, which makes them an "irreconcilable" enemy for others. For example, milk has B-like lectins, and if it is used by the "bearer" of the II blood group, then the body immediately begins the process of agglutination in order to reject this product. The most innocuous, to what this binding of cells can result, is irritation of the gastrointestinal tract.
The immune system does not quite protect us from lectins - phytohemoagglutinins: 95% of them are excreted from the body, but at least 5% penetrate into the blood, where they exert a destructive effect on blood cells, often leading to anemia. Even a scanty amount of a lectin threatens to agglutinate a large number of cells, especially if the "wrong" blood group contributes to it. That is why it is worth considering the recommendations on the recruitment of products that correspond to a certain blood group. Lectins (especially common cereal lectins (wheat) - gluten) slow down the metabolism of insulin, depriving the effective use of energy resources, calories, lead to obesity. Due to atrophy of the mucosa of the upper sections of the small intestine, chronic unstable stools, lack of appetite, weight loss, anemia occur. The satellite of negative effects of lectins is hypothyroidism with fatigue, increased sensitivity to cold, edema, weight gain.
When choosing a diet, based on the characteristics of the blood group, you should take into account the degree of influence of these or other products on the increase or decrease in body weight. The daily diet of the blood group was destined to become the most justified dietary regimen. In it it is necessary to distinguish especially useful products acting in the role of health, and neutral, acting only as a source of nutrition. Avoid products that are undesirable in your blood group.
If you are interested in this idea, you, of course, will not be satisfied with its brief presentation in this article. The best thing is to get a book about everyday nutrition by blood group. And then you will be able to thoroughly study the recommendations of the American scientist not only on nutrition according to his blood group, but also to strengthen his health. And also for the prevention of diseases, which are predisposed to belonging to this blood group, the most useful for you types of physical activity, effective ways to relieve stress.
