Does blood type really have anything to do with longevity? Type A, Type B, Type O, Type AB, which blood type is more likely to get cancer
Recently, I saw such a rumor that type O blood is a kind of longevity, as long as people have type O blood, people will not get cancer. However, the comments below keep coming. Some people say that blood type O is more likely to suffer from cancer, but others say that blood type does not determine life at all, nor can it predict the occurrence of cancer. All it can really do is character.
Does blood type really have anything to do with cancer? With your doubts, let us find out and see the mystery of blood type.
01 Is blood type really related to longevity? Type A, Type B, Type O, Type AB, which blood type is more likely to get cancer.
Blood type refers to the type of antigens on the surface of blood components (including red blood cells, white blood cells and platelets). Generally speaking, blood type refers to the specific antigen type on the red blood cell membrane, which is most closely related to clinical practice. It is known as the red blood cell AB blood group system and the Rh blood group system.
A blood type.
The ABO blood type is based on whether antigen A and antigen B are present on the red blood cell membrane, and blood is divided into four blood types. Only antigen A is type A on red blood cells, and only antigen B is type B. If both A and B are present, the antigen is type AB, neither of which is present.
Human serum of different blood types contains different antibodies, but does not contain antibodies against self-red blood cell antigens. For example, type A serum contains only anti-B antibodies. Among people of all nationalities in China, blood types A and O account for about 30%, and type AB only accounts for 10%.
Rh blood type:
Human red blood cells have the same antigens as rhesus monkeys, which are called Rh positive blood types, and those without this anti-principle are called Rh negative blood types. Among the Han and most ethnic minorities, Rh-positive blood types account for about 99%, while Rh-negative blood types only account for about 1%.
The Rh blood group system is the most complex among red blood cells, and more than 40 Rh antigens have been discovered, among which the D antigen is the strongest. Therefore, the D antigen on red blood cells is often called Rh positive, while the lack of D antigen on red blood cells is called Rh negative.
02 Is blood type really related to longevity?
At one point, a doctor and mathematician, Steven, M. Weisberg, and another fitness expert did a questionnaire. Type O blood has the longest lifespan. After scientific calculation and analysis, it is found that the average life expectancy reaches 87 years, the average life expectancy of B blood is 77 years, the average life expectancy of AB blood is 70 years, and the life expectancy of A blood is the shortest, and the survey results are all 62 years old.
Psychologists have done relevant research and found that people with blood type A are always introverted, sensitive, and shy. To use a popular word to describe it, it is social fear. People with this social phobia have difficulty communicating normally with others. They will describe various scenarios in their heads to prevent embarrassment and jokes.
At this point, it is not difficult to see that people here are more likely to blush because they are always more sensitive, causing them to care too much about others, and caring too much about others will increase their burden. Once there is a burden, the body will reflect various diseases and protest, So type A blood has a short lifespan.
Will there be other changes in the long-lived elderly? Taking Beijing, China as an example, the blood types of 100 long-lived people over 90 years old were analyzed, and it was found that their hemoglobin, white blood cells, white blood cell classification, reticulation, and cell blood type distribution had changes to varying degrees.
1. In terms of gender: the hemoglobin of the long-lived elderly has no obvious abnormality, which may be due to the decreased secretion of sex hormones. For example, older men have less testosterone and women have more estrogen, so the gap narrows.
Another value is white blood cells. Men's white blood cells decreased, and women's white blood cells did not change much. From the perspective of cell classification, the leukocyte classification of the long-lived elderly has changed significantly, which indicates that the immune function decreases with age, and there is no obvious change and difference in network cells.
2. Blood type distribution: There are more people with O blood type, accounting for 40%, followed by A blood type, accounting for 28%. The survey found that the average life expectancy of people with blood type A is 62 years. Type B blood has an average life expectancy of 77 years, while type O blood has an average life expectancy of 87 years. For this survey data, it was concluded that people with type O blood live longer, leading to the rumor that blood type can determine life expectancy.
In fact, it is easy to break this rumor. Other scholars have done similar experiments. They conducted surveys in other areas and found that type B blood lived longer, while survey data from Japanese scholars showed that type A blood lived longer.
Therefore, it is easy to draw different conclusions from different samples and different sampling locations. Therefore, this theory is not universal and not scientific enough. The point is that there is no inevitable causal relationship between blood type and longevity.
03 Type A. Type B. Type O.
Although a large number of studies have confirmed that blood types are closely related to cancer, in terms of overall cancer mortality, there is no significant difference between different blood types. Blood type is only one of the factors affecting the occurrence of cancer, which is an internal cause of cancer. In addition to the internal causes of cancer, there are also external causes, such as gene mutations, eating habits, viral infections, and long-term exposure to carcinogens.
Usually, I like to eat hot food, eating irregularly, eating too much, like eating fried and grilled food, which may increase the incidence of esophageal cancer, gastric cancer, oral cancer, laryngeal cancer and other cancers. Therefore, there is no scientific basis to say which blood type is more prone to cancer.
04 These diseases may be related to blood type.
In addition to cancer blood type, there are certain links:
People with blood type A are closely related to coronary heart disease. Studies have found that the concentration of total cholesterol and low-density lipoprotein cholesterol (LDL-C) is higher.
Patients with blood type B are closely related to diabetes. The study found that women with type A blood have a 10% higher risk of developing diabetes than women with type O blood, and women with type B blood have a 21% higher risk of developing diabetes than women with type O blood.
People with O blood type are more likely to suffer from peptic ulcers, because peptic ulcers are related to Helicobacter pylori infection, and Helicobacter pylori prefers to invade people with O blood type and destroy their gastric environment and gastric parietal cells.
People with AB blood type have poor memory. Studies have found that people with AB blood type have memory loss in later life, which is more serious than other blood types, so they are more likely to suffer from Alzheimer's disease.
05 These four factors determine the length of human life!
- Genetic factors: Human life span has a lot to do with genes. It is well known that men and women have different genes. Males have more chromosomes than females. Studies have shown that the average life expectancy of women is higher than that of men, which is also caused by genes.
In males, there are genes that impair their lifespan, so males tend to have a relatively short lifespan. Male friends should pay attention to developing good living habits, so as to prolong their lifespan.
Psychological factors: Psychological factors are also called personality factors. Studies have shown that maintaining a positive and optimistic attitude can prolong life. If you're in a good mood, you're less likely to get sick. If you are in a state of great stress and depression for a long time, the mental state and physical condition of the whole person will not be good, which will lead to the emergence of diseases and shorten people's life span.
Dietary factors: Dietary factors are the biggest factors affecting life expectancy. An unhealthy diet can shorten lifespan. For example, eating irregularly, not eating at times, eating a lot when you are hungry, and the food you eat is also fast food. This habit is very harmful to the stomach.
Usually like to eat some junk food and fast food, which is not very healthy, because these foods can cause cancer, cancer is difficult to cure, and has a great impact on life, so usually eat more fruits and vegetables, maintain good eating habits, It has a great effect on the body.
- Living habits: A person's living habits are also very important. Generally, smoking, drinking and staying up late are very harmful to the body, especially staying up late. Staying up late is tantamount to slow suicide. The more you stay up late, the shorter your lifespan. Therefore, you must develop good living habits.
Warm reminder: The occurrence of cancer is related to various factors. It is very unscientific to rely on blood type to judge whether you will have cancer. Do not believe rumors in daily life.
