Is blood type related to longevity? Type A, Type B, Type O, Type AB, are there different cancer risks?
What blood type are you?
Some people say that people with blood type A pursue perfectionism, from the beginning to the end, people with blood type B love freedom, full of vitality, type AB sensibility, full of innocence, people with type O blood are open-minded and goal-oriented, and do not know how to refuse...
As magical as it sounds, blood type determines personality and is not universally recognized. However, scientists have confirmed that the ABO blood type is associated with a variety of diseases, which blood type is most prone to cancer?
- Study finds: B blood types with low cancer risk
For many years since the discovery of blood type by ABO in 1901, blood type seems to be closely related to the development of cancer.
In 1953, it was found that blood type A was associated with the occurrence of gastric cancer. In order to understand the relationship between blood type and cancer in China, Yuan Jianmin's team from Shanghai Jiao Tong University/University of Pittsburgh has been following up for more than 20 years since 1986.
A total of more than 18,000 volunteers participated in the study, of whom 32% were blood type O, 31% were blood type A, and 27% were blood type B, AB, 3,973 people with cancer, digestive Systemic tumors were the most common tumors, accounting for 51% of total cases.
The study found:
①The risk of digestive system tumors is about 20% lower than that of people with type A blood;
Specifically, B gastric cancer risk was reduced by 25%, and colorectal cancer risk was reduced by 22%; AB gastric cancer risk was reduced by 24%, and colorectal cancer risk was reduced by 32%; the difference.
② AB blood type has the highest risk of liver cancer, which is the highest risk of liver cancer than non-type blood. AB is 42% higher than A type and 45% higher than A blood type;
But AB blood type and O blood type can reduce the risk of pancreatic cancer compared with A blood type, AB can reduce the risk of pancreatic cancer adenocarcinoma risk by 17%, O can reduce the risk of pancreatic cancer by 15%.
③ Overall, blood group B antigens were associated with lower tumor risk. ABO blood type and risk of lung cancer. Skin cancer. Prostate cancer. Connective tissue tumors. Bone cancer risk is irrelevant.
- Does blood type determine life expectancy?
Why might ABO be linked to cancer? Some scholars put forward some hypotheses:
Some tumor antigens are similar in structure to ABO blood group antigens, so the antigens of these tumors may be disguised as blood group antigens to avoid recognition and attack by human immune cells.
ABO glycosyltransferases are required to participate in intercellular adhesion. Host immune responses. If the activities of these enzymes are unbalanced, cell membrane signaling pathways and the processes of angiogenesis and apoptosis may promote the occurrence of cancer.
3.ABO blood group antigen may affect the inflammatory response of the whole body, and it will affect the inflammatory response of the whole body.
However, research on the link between various blood types and cancer is still a long way off. More research is needed on how blood type affects cancer.
Cancer is a combination of factors, so don't judge or worry too much based on blood type.
There are also studies that speculate on the relationship between blood type and other diseases:
① Blood type 0: risk of heart disease. Low risk of Alzheimer's
In 2012, researchers at the Harvard School of Public Health tracked 89,500 adults for 20 years and found that blood type O had the lowest risk of heart disease;
In addition, researchers at the University of Sheffield performed magnetic resonance imaging scans of the heads on 189 healthy volunteers. Then, through an analysis of the data, it was found that people with more gray matter in the brain were those with type O blood, and that a reduction in the volume of gray matter in the brain increases the risk of Alzheimer's disease and other diseases. Therefore, people with blood type O have a lower risk of developing Alzheimer's disease.
②AB blood type: more prone to thrombosis
There is also a certain relationship between blood type and thrombosis. A study published in the journal Circulation found that an important risk factor for thrombosis is that the AB blood type accounts for about 20% of the causes of blood clots.
③B-diabetes prone blood type
In a French study published in the journal Diabetes, after analyzing more than 80,000 patients, it was found that the risk of type 2 diabetes was 21% higher than that of those with type O blood, that is, the difference between diabetes and type B blood. There may be correlations between them.
Currently, however, the relationship between blood type and life expectancy is uncertain. These studies may be influenced by other factors. For example, people participating in a survey may be specific to a population or location. Additionally, conclusions may be affected by legal differences. Sampling error. Contributing factors such as racial stratification or ethnicity.
- If you want to live a long life, don't count on blood type. Do these more reliably
Instead of counting on your blood type to live a long life, do these things well:
- Be optimistic. Have a good attitude
Negative emotions can affect the body's metabolism and reduce immunity.
A study published in PNAS found that optimistic people may live longer, even beyond the age of 85.
Therefore, we must have an optimistic attitude. When encountering difficulties, we must think from multiple perspectives, adjust our pessimistic thoughts in time, and maintain our love for life.
- Stay fat, but not fat
In terms of longevity, people who gain a little weight may have an advantage as they age.
According to a 2020 study from The Ohio State University, healthy body mass index (BMI) weight gainers gradually increased, but people who did not reach obesity levels lived the longest.
If you are already obese in adulthood and gain weight afterward, you will have a higher mortality rate.
- Healthy living habits
Professor Hu from Harvard School of Public Health pointed out in a study published in the journal "Circulation" that he insisted on not smoking. Sticking to exercise. Healthy eating. Maintaining a healthy lifestyle, such as a healthy weight, can greatly reduce the risk of cancer and cardiovascular disease risk, extending life expectancy after age 50 by more than 10 years.
- Participate in social activities
Social activities can also have a certain impact on life. Social activities can not only increase a sense of identity, but also reduce loneliness and reduce the risk of Alzheimer's disease and depression.
According to the last study in Social Sciences, positive social relationships and survival increased by 50%, and isolated social groups were associated with a 29% increased risk of cardiovascular disease and a 32% increased risk of stroke.
In short, there may be a link between blood type and certain diseases, but if you want to live a long life, you can't rely on blood type, quit bad habits, and live a healthy life is more important.
