Does blood type determine life expectancy? Scientists study 600,000 people and conclude that type O blood may lead to longer life

Regarding blood type, there are many sayings circulating on the Internet. Some people say that a person’s personality can be seen from the blood type, and some people say that type A blood or “naturally” is more prone to stroke, while type O blood has the longest life span, which has caused endless debate.

Can the blood type on the "cusp of the storm" really predict the physical condition? Recently, researchers from the University of Maryland in the United States have made a study on this and found that people with type A blood have a higher risk of stroke before the age of 60.

Study finds: Type A blood more likely to have a stroke

In this study, the researchers collected 48 studies on genetics and ischemic stroke, including 16,730 stroke patients and 599,237 healthy people, and then analyzed all the collected chromosomes to find out whether there is a relationship between stroke and stroke. The associated genetic variation eventually found a link between early-onset stroke before age 60 and a region of the chromosome that determines blood type.

In these early-onset stroke groups, the proportion of blood type A was the highest, accounting for 48%, while the proportion of blood type O was the lowest.

After adjusting for gender and other factors, the researchers compared the data again and found that type A blood had a 16 percent higher risk of early-onset stroke, while type O blood was 12 percent less likely. However, it should be noted that this study can only prove that there is a certain relationship between blood type and early-onset stroke, but the increase in stroke is not directly related to blood type, so people with blood type A do not need to worry too much.

O blood type is related to longevity?

In fact, as early as 1961, a study revealed the link between blood type and life expectancy. By collecting the blood of 50 people over the age of 90, the researchers finally concluded that there is no correlation between ABO blood type and life expectancy, but O blood type seems to be closely related to longevity.

Although there is no clinical data to prove it, it still drives people to yearn for O-type blood. Many foreign rich people are even willing to take the risk of replacing young O-type blood in order to make the body "return to youth".

However, as far as the current technology is concerned, there are still many risks in blood replacement. In addition, type O blood is not "universal blood". Although the red blood cells of type O blood do not contain A and B antigens, the plasma does contain Antibodies A and B, once transfused into the body of other blood types, will destroy the patient's original normal red blood cells, thus posing a threat to life.

With the current anti-aging technology at the blowout node, there is a safer way to return the body to a younger age. In 2013, Harvard geneticist Sinclair accidentally discovered an anti-aging substance called "Wright Weijian" that can reverse the aging of organisms and prolong the lifespan. When it first came out, the threshold was as high as 20,000 yuan. one gram.

At the same time, Keio University also confirmed in clinical trials that after the subjects received the external intervention of "Lightway Health" anti-aging substances, many physiological indicators of the body tended to be younger. Reliable "blood replacement", the potential of this substance to interfere with aging is more convincing.

In recent years, with the participation of many domestic and foreign bio-companies, the cost of "Wright Weijian" material has also achieved a cliff-like decline. After iterative quantification, it finally sank to Jingdong-Tmall at a 4-digit price . Although the threshold is still not close to the people, it still cannot resist the fans of high-net-worth groups. In their view, "spending money to buy health" has become a "new rigid demand", which also reflects people's self-confidence health is also more important.

Blood type is not everything

Throughout the ages, there have been countless studies on blood types. Although relevant personnel have revealed the statement that type O blood may live longer, it is too early to make such an assertion from the perspective of clinical trial guidance.

All in all, no matter what blood type you are and what risks they represent, in our daily life, if we can pay attention to a healthy diet and a regular healthy life, I believe that our physical condition will be better.

The United States once conducted a 9-year study on men and women with different lifestyles, and found that the impact of people's lifestyles on their health far exceeds the sum of other factors. In short, a healthy lifestyle It is an important factor affecting life expectancy!
