Whether blood type nutrition is effective or not?

Many exotic diets are based on facts, the scientific evidence of which, when tested, is very “lame”. This happens because the hopes for the normalization of body weight are sometimes associated with absurd and anti-scientific ideas, and empirical evidence of the effectiveness of such diets is the result of completely different processes occurring in the body with certain nutritional characteristics. The question of whether nutrition by blood type is effective or not can be answered with several scientifically proven facts.

Why does blood differ by group? A number of protein compounds responsible for blood clotting may be present in human blood: agglutinins (found in the blood plasma) and agglutinogens (found on the surface of the red blood cells themselves). These proteins are responsible for the clotting of other types of blood (they cause an agglutination reaction - erythrocytes stick together and precipitate, followed by the formation of clots). The agglutination reaction is an ancient biological mechanism for protecting the body from foreign protein compounds, in which agglutinogens act as erythrocyte antigens, and agglutinins play the role of antibodies in human blood plasma. When mixing the blood of different people, the mechanism of searching for erythrocyte antigens by blood plasma antibodies begins to work. This reaction is similar to immune reaction to search for and neutralize foreign antigens with antibodies. The agglutination reaction acts as a protective mechanism of human life support. Erythrocytes, recognized as foreign proteins - antigens, are toxic and cause hemotransfusion shock, which can lead to the death of the human body.

Empirically, biochemists have found that such proteins are found in erythrocytes and in the blood plasma of all people, but in various combinations. In the erythrocytes of the first blood group (0) there are no antigenic proteins, and in the fourth blood group (AB) there are no agglutinins (antibodies) in the plasma. Those who do not have antigenic proteins in their blood erythrocytes are universal donors. Thus, in a number of multiple combinations of blood from different people, four types of blood were identified - which were called groups, and according to these groups, blood transfusions are carried out, pregnancy planning, but they do not agree on the structure of nutrition.

The biochemical composition of blood suggests that people do not have absolutely the same blood due to the fact that their genetic characteristics (transfer of blood type and Rh factor by inheritance), nutrition and living environment directly affect the composition of the blood. There are a number of universal quantitative indicators of the substances that make up the blood - these are blood-forming elements (norm and deviation from the norm), and the rest is added by the person himself, eating according to his preferences and abilities, living in an impeccably clean atmosphere and in stresses that significantly change the composition of the blood.

For each person, the process of nutrition and digestion is purely individual, since there is a set of digestive enzymes, which can be different both in composition and concentration of these enzymes during their secretory release into the digestive tract. Accordingly, the quality of digestion, and with it the volume of absorbed substances, will vary greatly. All this has nothing to do with the blood type, but is directly related to physiological processes and their disturbances in metabolism and in the process of digestion and assimilation of food.

Some people have substances in the body that prevent the digestion and absorption of certain food components, such as gluten or histamine, which also affects the quality of digestion, but is not associated with blood groups.

Under such nutritional conditions, no blood type diet will work. The blood type is important only for transfusion in emergency cases, but not in nutrition for the formation of the required body weight.

The effectiveness of nutrition by blood type depends more on the psychological mood of a person to normalize weight. Such a psychological factor will not cause harm if they do not deviate in nutrition towards extremes that are unacceptable for life support, such as starvation, monotonous and poor nutrition, and artificial restriction of the consumption of vital products (proteins, fats and carbohydrates).

All useful elements for the structure of organ tissues must be present in the blood, regardless of what type of blood a person has. But the composition of the blood matters, as it reflects the entire palette of incoming nutrients, as well as violations in their absorption. Therefore, correlating nutrition with blood composition, it is necessary to take into account the indicators of the norm of blood composition, but not blood group.
