How about AB blood? Please talk about its advantages and disadvantages.

In favor: the immune function and adaptability to the environment of AB type people are the best among the four blood types. Type AB blood is a mixture of type a blood and type b blood, which can adapt to changes in diet, life and environment.

Disadvantages: people with AB blood type have both characteristics of A and B, so they are prone to heart disease, alcoholism, pneumonia and urethritis. Because of its weak digestive organs, basically foods with blood type A and B are not suitable for people with blood type AB.

Advantages and disadvantages of other blood types in extended data:

1, type o: the risk of pancreatic cancer is low. A study by Yale University in the United States found that people with type O blood have a relatively low risk of pancreatic cancer. Scientists have found that there are no two specific antigens carried by blood groups A and B on the surface of red blood cells of type O people, so the risk of pancreatic cancer is relatively low.

2. type a: it is easier to be anxious. It is found that type A people have higher levels of cortisol (a stress-related hormone), so they are more prone to anxiety. Once they are in trouble, it will take longer to solve it. Instead of running and lifting weights, it is better to do more sports such as Tai Chi and Yoga. The study also found that AB people can enhance their immunity by doing various exercises. Dr. Ginger Nash, an American naturopathic expert, said that type O people can't excrete cortisol quickly, so they are slow to produce stress and relieve stress.

3. Type B: The most beneficial bacteria are in the intestine. The results showed that the number of beneficial strains in the intestine of type B people was 50 thousand times that of type A and type O people. Dr. Peter DeDamon, an American naturopathic expert, said that more and more studies show that changing the microbial content in the digestive tract can alleviate or treat metabolic diseases such as type 2 diabetes and obesity. Blood type and endocrine status play a decisive role in the overall health of digestive tract.

Characteristics of AB blood group:

AB blood cells have corresponding antigens, but because blood cells are the main input, there is less serum and lectin, and lectin is less bound to antigens, which is safer.

Type AB blood is called universal recipient, but the amount of blood transfusion should not be too large. It can only be used in emergencies (such as the battlefield), and the safety factor is not high.
