So why do some people think that people with type O blood should eat less whole grains and people with type A blood should eat less meat? Their theory is this:
They believe that type O blood is the earliest blood type in the world. At that time, people mainly ate animal meat, and such people often had a better digestive system. Therefore, it is recommended to eat more high-protein foods such as meat and fish, and try to eat less whole grains, otherwise it will become fat and be stored in the body.
As for type A blood, they think that these people's stomach acid level is relatively low, and their digestive ability is much weaker for some high-protein and high-fat foods such as meat. In order to avoid indigestion, such people try to eat less meat and more vegetables.
But to be honest, these theories have no scientific basis and are all made up. A person's digestive system has nothing to do with blood type, so naturally there is no question of what blood type should and should not eat. The reason to distinguish blood types is not to classify food, but because people have different blood types. When a large number of blood transfusions are needed, if the input blood type is different from your own, it will start the epidemic prevention system in the human body and attack this part of the blood, leading to adverse reactions, which is not conducive to blood transfusion treatment. Therefore, it is necessary to distinguish blood types to achieve the best therapeutic effect.
It is also said that people with certain blood types tend to get fat, while people with certain blood types don't. This is a fabrication. If a person eats casually and does not exercise, do you think he will get fat in the long run, so we should not believe such rumors. Now the network is developed, the news spreads quickly, and it is easy to spread to all places, making people believe it. We should learn to distinguish the authenticity of such news.
