Is blood type really related to longevity? A type, B type, O type, AB type, which blood type is more prone to cancer
Recently, I saw such a rumor that type O blood is a kind of longevity, and as long as it is type O blood, people will not get cancer. However, the comments below keep coming. Some people say that blood type O is more prone to cancer, but others say that blood type does not determine life at all, nor can it predict the occurrence of cancer. What can really do is character.
Is blood type really related to cancer? With your doubts in mind, let's take a closer look at the mystery of blood types.
01 Is blood type really related to longevity? A type, B type, O type, AB type, which blood type is more prone to cancer.
Blood type refers to the types of antigens (including red blood cells, white blood cells, and platelets) on the surface of blood components. 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 called the red blood cell AB blood group system and the Rh blood group system.
A blood type.
The ABO blood group is based on the presence or absence of antigen A and antigen B on the red blood cell membrane, and blood is divided into four blood types. Only antigen A on red blood cells is type A, and only antigen B is type B. If both A and B are present, the anti-principle is type AB, and neither antigen is present.
Human sera of different blood groups contain different antibodies, but do not contain antibodies against their own red blood cell antigens. For example, type A serum contains only anti-B antibodies. Among the people of all ethnic groups 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 antigen as rhesus monkeys, called Rh-positive blood group, without this anti-principle is called Rh-negative blood group. Among the Han and most ethnic minorities, Rh-positive blood type accounts for about 99%, while Rh-negative blood group accounts for only about 1%.
The Rh blood group system is the most complex of the red blood cell types, and more than 40 Rh antigens have been found, among which the D antigen is the strongest. Therefore, D antigen on red blood cells is often referred to as Rh positive, while D antigen deficiency on red blood cells is referred to as 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 life expectancy. After scientific calculation and analysis, it was found that the average life expectancy is 87 years old, the average life expectancy of type B blood is 77 years old, the average life expectancy of blood type AB is 70 years old, and the life expectancy of blood type A is the shortest, and the survey results are all 62 years old.
Psychologists have done related research and found that people with blood type A are always introverted, sensitive, and shy. A popular word to describe them is social fear. People with this social fear have difficulty communicating properly with others. They will describe various scenarios in their minds to prevent humiliation and jokes.
At this point, it's not hard to see that people here are more prone to blush because they are always more sensitive, which causes them to care too much about others, which will increase their burden, and once there is a burden, the body will reflect various disease protests, So type A blood has a very short lifespan.
Will there be other changes in the elderly with longevity? Taking Beijing, China as an example, the blood type of 100 long-lived elderly people over 90 years old was analyzed, and it was found that their hemoglobin, white blood cells, white blood cell classification, reticulum and cell blood type distribution all changed to varying degrees.
1. In terms of gender: the haemoglobin of the long-lived elderly is not significantly abnormal, which may be due to the decreased secretion of sex hormones. For example, testosterone production in older men decreases and estrogen production in women increases, so the gap narrows.
Another value is white blood cells. Men's white blood cells decrease, and women's white blood cells do not change much. From the perspective of cell classification, there were significant changes in leukocyte classification in the long-lived elderly, which indicated that immune function decreased with age, and there were no obvious changes and differences in network cells.
2. Blood type distribution: The number of blood type O is more, accounting for 40%, followed by blood type A, accounting for 28%. The survey found that the average life expectancy of people with blood type A is 62 years. The average life expectancy for type B blood is 77 years, while the average life expectancy for type O blood is 87 years. For this survey data, it was concluded that people with blood type O live longer, leading to the rumor that blood type can determine lifespan.
In fact, it's easy to break this rumor. Other scholars have also done similar experiments. They conducted surveys in other regions and found that blood type B had a longer lifespan, while Japanese scholars' survey data showed that blood type A had a longer lifespan.
Therefore, different samples and different sampling locations can easily draw different conclusions. 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 type is closely related to cancer, there is no significant difference between different blood types in terms of overall cancer mortality. Blood type is only one of the factors that affect the occurrence of cancer, which belongs to the internal cause of cancer occurrence. In addition to internal causes of cancer, there are also external causes such as genetic mutations, dietary habits, viral infections, and long-term exposure to carcinogens.
Usually, I like to eat hot food, gobble irregularly, eat too much, and like to eat fried and grilled food, which may increase the incidence of esophagus, stomach, mouth, throat and other cancers. Therefore, there is no scientific basis for which blood type is more likely to develop 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, and studies have found that total cholesterol and low-density lipoprotein cholesterol (LDL-C) concentrations are higher.
Patients with type B blood are closely related to diabetes. The study found that women with type A blood had a 10 percent higher risk of diabetes than women with type O blood, and women with type B blood had about a 21 percent higher risk of diabetes than women with type O blood.
People with blood type O are more likely to develop peptic ulcers because peptic ulcers are associated with Helicobacter pylori infection, and Helicobacter pylori prefers to invade people with blood type O to destroy their stomach environment and gastric parietal cells.
People with type AB blood have poor memory. Studies have found that people with type AB blood have a worse 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 a person's lifespan!
- Genetic factors: Human lifespan has a lot to do with genes. It is well known that males and females have different genes. Men have more chromosomes than women. Studies have shown that women have a higher life expectancy than men, which is also caused by genetics.
In males, there are genes that impair their longevity, so males will have a relatively short lifespan. Male friends should pay attention to develop good living habits, thereby prolonging their lifespan.
Psychological factors: Psychological factors are also known as personality factors. Research shows that maintaining a positive and optimistic attitude can increase life expectancy. 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 appearance of diseases and shorten people's lifespan.
Dietary factors: Dietary factors are the biggest factor affecting longevity. An unhealthy diet can lead to a shorter lifespan. For example, eating irregularly, sometimes not eating, 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 a good diet, have a great impact on the body.
- Living habits: A person's living habits are also very important. Usually smoking, drinking and staying up late are very harmful to the body, especially staying up late. Staying up late equals chronic suicide. The more you stay up late, the shorter your lifespan. Therefore, you must develop good living habits.
Reminder: The occurrence of cancer is related to various factors. It is very unscientific to rely on blood type to determine whether you will have cancer. Do not believe in rumors in daily life.
