Blood group AB is actually a blood group, which means that human serum does not contain anti-A and anti-B antibodies. Although AB blood cells have corresponding antigens, they are mainly imported from blood cells, so there is really little serum, so there is little lectin imported, and the combination of lectin and antigen is relatively safe. Now many of us call AB blood universal blood, but the amount of blood transfusion should not be too large. Generally speaking, it can only be used in emergencies (such as the battlefield of death), and the safety factor is not high. People with AB blood have both characteristics of type A and type B, so they are very prone to heart disease, alcoholism, pneumonia and urethritis. Having said that, the immune function and ability to adapt to the environment of AB type people are the best among the four blood types. So in our daily life, we really don't need to have any special views on our health because of our blood type.
People with AB blood type have better metabolism of plant food, but relatively poor metabolism of animal food. Therefore, after entering the age of 50, they can appropriately increase the intake of vegetarian food and appropriately reduce the intake of meat. In addition, compared with other blood types, people with AB blood type are more prone to dyslipidemia. There may be some friends here who have doubts. Since people with AB blood type have poor digestive function, it means that they are prone to malnutrition. How can there be dyslipidemia? In fact, the fundamental reason is this: the most important thing for human blood lipids is in vivo synthesis, followed by intake from food.
