Type A, type B, type AB, type O, which blood type has good physical fitness? listen to the doctor's explanation

Since Landsteiner discovered the first human blood group system in 1901, the ABO blood group system, 35 different red blood cell blood group systems have been discovered. The ABO blood group system and the Rh blood group system are most closely related to clinical practice.

These four types of blood have a certain incompatibility, that is, when one type of blood needs a transfusion, it can only lose the matching blood type. Type O blood can donate blood for any of the other three blood types, while type O blood itself can only be accepted.

Type AB blood transfusion can accept donations from any blood type, but as an exporter, it can only lose to type AB. How are these blood types distinguished? Now let's see.

01 Methods to distinguish different blood types.

Type A blood means that an antigen is expressed on the surface of the red blood cell membrane, and its serum does not express B antibodies. Type B blood means that B antigens are expressed on the surface of red blood cell membranes, but A antibodies are not expressed in serum. Type O blood does not express A antigen nor B antigen, and its serum contains A antibody and B antibody. Type AB blood expresses both A and B antigens, and there are no antibodies in the serum.

According to the expression of D antigen on the surface of erythrocyte membrane, the Rh blood group system is divided into Rh negative blood and Rh positive blood.

02 The role of blood

We differentiate between different blood types based on certain components in the blood. Do you know the important role of blood in the human body?

1. Shipping.

The blood gets oxygen from the lungs, nutrients from the digestive tract, and then transports the oxygen and nutrients to all the tissues of the body. Carbon dioxide and waste from other parts of the body are transported to the excretory, which plays an important role in transport.

2. Immune function .

Plasma contains a variety of immune substances, such as antitoxins and lysins, which fight or destroy foreign bacteria and toxins, thereby protecting the body from infectious diseases. In addition, white blood cells can phagocytose foreign microorganisms and ring dead tissues in the body, and have a good defense function.

3. Buffer.

The levels of water and minerals in the blood are relatively constant. As a buffer system, plasma not only maintains the acid-base balance between the plasma itself and the extracellular fluid, but also maintains a relatively constant pH when acidic or basic substances enter the blood.

Of course, our blood can also regulate body fluid balance through colloid osmotic pressure. In addition, the water in the plasma also regulates body temperature.

03 Is blood type related to health?

We know that blood types are more refined when transfused, but few people know that blood types are actually closely related to our health. Next, let's talk about the close relationship between blood type and health.

1. blood type A

Most people with blood type A are workaholics and usually need to pay more attention to coping with stress. If you stay up too late, your vascular health can also suffer. Therefore, people with type A blood need to pay more attention to this aspect of their health. In the usual health work, we must pay attention to maintaining regular work and rest, and know how to release stress.

2. Type B blood

In addition to being susceptible to dental caries, B-type friends are also generally more likely to suffer from tuberculosis, oral cancer, breast cancer and leukemia than other blood types.

But they have good metabolic function, can discharge waste and toxins from the body in a short time, and effectively maintain cardiovascular and cerebrovascular health. It should be noted that patients with blood type B should protect the health of lung function, eat more heat-clearing and detoxifying foods such as pears and white fungus, and stay away from cigarettes.

AB blood type.

Patients with type AB blood have a rapid neurological response. Although this blood type suffers from tuberculosis, the probability of anemia during pregnancy is much lower than other blood types, but they are prone to ischaemic heart disease and schizophrenia. At the same time, coronary heart disease and cervical cancer are also easy to patronize.

4. Type O blood

People with type O blood may feel that their blood type is healthier because they all say that type O blood is everything. To a certain extent, people with type O blood do have a relatively strong metabolism, relatively good body repair ability, less likely to suffer from any serious diseases, healthier and more likely to live longer. But this is not absolute, usually or through a sensible diet and more exercise to ensure physical and mental health.

04 A healthy diet guide for people with different blood types.

1. blood type A

People with blood type A typically produce less gastric acid, which makes them less able to digest meat. Therefore, they should be careful with beef, lamb and other meats. If you eat a lot of meat and suffer from indigestion, it is easy to accumulate a lot of fat in the body, leading to obesity.

Therefore, if people with blood type A want to lose weight, they must be careful to eat meat such as beef and mutton. It is best to use fresh fish and chicken instead.

2. Type B blood

People with blood type B are prone to cardiovascular and cerebrovascular diseases and hyperlipidemia because their blood is viscous. Therefore, dietary principles should eliminate the intake of high-fat diets, which are beneficial to maintain healthy vital signs.

In general, you can supplement with moderate amounts of soy products, corn, and soapy rice to prevent high-cholesterol foods and high-fat meats. When eating meat, you can also eat fish and a small amount of fatty donkey meat.

3. AB blood type.

People with type AB blood are not only adapted to animal proteins, but also to plant proteins. These people have a more sensitive digestive system and should eat smaller meals more often. Usually, fish, tofu, green leafy vegetables and dairy products can be properly supplemented as their healthy food.

4. Type O blood

For people with blood type O, if you want to be healthier, you can eat more meat rich in high-quality protein. It's important to note that people with blood type O are relatively poor at digesting bread and grains, so they can't eat more, or they'll easily gain weight.

05 Tip: Doing this will help keep your blood vessels healthy.

1. A reasonable diet.

In daily life, we should pay attention to the rules of three meals, balanced nutrition, eat less food high in sugar, oil, fat and salt, and eat more food rich in dietary fiber, such as grains, dried beans, dark vegetables and fresh fruits. These all help to remove blood waste and metabolize excess fat in blood vessels, thereby enhancing the elasticity of blood vessels.

2. Eat nuts in moderation every day, dark chocolate.

Nuts are rich in unsaturated fatty acids. Moderate consumption of nuts can effectively reduce the content of bad cholesterol in the human body. To a certain extent, it can improve vascular endothelial function and help our blood vessels to be healthy.

In addition to eating some nuts, eat a little dark chocolate. The polyphenols contained in dark chocolate have antioxidant properties and also make our blood vessels younger.

3. Quit smoking as soon as possible.

Tobacco is considered the enemy of cardiovascular health. Harmful substances in tobacco smoke can easily cause coronary artery spasm, myocardial ischemia and hypoxia, accelerate the process of atherosclerosis, and easily form thrombus.

4. Exercise more

Regular exercise can not only lose weight and shape, but also enhance physiological functions, and it is also an important way to prevent, treat and recover many cardiovascular diseases.
