Principles on which blood type formula is based.
1, gene theory
According to the research of some scientists, the ancestors of many ancient people were hunters, such as Eskimos in Alaska and some native Indians in the United States. Their food rarely included vegetables. However, they have no problems with cancer or heart disease. This is because their blood types are mostly O type.
Blood type A is the second most common blood type. Compared with people with type O blood, people with type A blood have much weaker digestive organs. The ancestors of people with type A blood were the first to engage in farming crops, and they were quite adapted to vegetarian food. Tofu, soybeans, eggs and vegetables are all suitable for them. Some plants, such as protein and soybean protein, are their best healthy food, which can prevent cardiovascular diseases and cancer if eaten regularly.
Compared with O type and A type, B type belongs to late blood group in anthropology. This kind of people are the first nomadic people to adapt to climate changes. Type B blood is easier to achieve balance in the human body and has a strong immune system. Therefore, it is unique in eating method, almost unlimited, extremely suitable for meat and vegetables, and dairy food is also very useful.
Type AB is the newest and rarest blood group, accounting for less than 5% of the total population. Can adapt to changes in diet and environment. This kind of person has the characteristics of part A blood and part B blood. They are suitable for both animal protein and plant protein, and the most suitable meat proteins for AB blood group people are mutton, eggs and fish and shellfish.
2. "Hemagglutinin" theory
Each blood type of human beings has a specific antigen, which acts on phytohemagglutinin (a kind of protein attached to food) in different ways. When the phytohemagglutinin in food "matches" the blood type of the consumer, it will have the effect of delaying aging, gaining ideal weight and improving immunity.
In daily life, hemagglutinin in most foods is not fatal at once, but through years of accumulation, even weak hemagglutinin similar to your blood type can cause various health diseases. Usually, the body's immune system will help the body filter out the hemagglutinin absorbed in the daily diet, but at least 5% of the hemagglutinin will slip into the blood, affecting or destroying red blood cells and white blood cells.

Expert tips
Li Qun, director of the Nutrition Department of Jiangsu Provincial Hospital, pointed out that there is no scientific basis for determining people's diet according to blood type. In fact, there is no nutritional survey on blood type in China at present.
If we deliberately choose food according to blood type, but ignore the food that may lead to obesity of a certain blood type, it may cause artificial partial eclipse. Whether eating meat or chocolate, as long as the overall calorie intake does not exceed the standard, you can achieve the goal of losing weight.
In real life, men and women are different, and people with different constitutions cannot have the same requirements for food, nor can they copy it mechanically. If citizens think they are obese and need to improve their diet, it is best to go to the nutrition clinic for consultation, and the doctor will tailor meals specifically for their physique. Healthy weight loss still requires a reasonable diet, a balanced diet and more exercise.
