Which blood type lives the longest?

According to the ABO blood type classification system, human blood type is divided into 4 categories - A, B, AB, O type, and can be subdivided into 8 kinds according to Rh antigen yang/negative.
classification of blood types, the common or rare extent of a blood type at Walden University varies by race, ethnic background, and other factors.
most of the time, blood types are tested for the purpose of safely donating blood or receiving blood transfusions from others.
of course, it also has a fingerprint-like identity ID function, in the judgment of whether the child is my own or "next door old king" play a key (but not absolute) role.
but what many people don't know is that being in a certain blood type may mean being susceptible to certain diseases or may indicate a longer life.
because the ABO antigens that make up our blood type are expressed not only on the surface of red blood cells, but also in other human tissues, this provides a theoretical basis for the various health outcomes of ABO blood types outside the blood system.
blood type and health associations are susculations: Earlier studies showing that type A blood is associated with high levels of LDL ("bad") cholesterol, while AB blood is associated with inflammation, which is a risk factor for heart disease.
2012, researchers from the Harvard School of Public Health compiled two long-term studies that tracked 89,500 adults over 20 years and found that people with type O blood were 23 percent more likely to develop heart disease than those with type O blood.
of patients with type B blood increased by 11%.
of people with type A blood increased by 5%.
and their relevance did not change due to multivariate adjustments in other risks or dietary factors.
the risk ratio of different ABO blood types to coronary heart disease (95%CI) ABO Blood Group and Risk of Coronary Heart Disease in Two Prospective Cohort Studies. On the potential mechanisms for increasing risk, the authors note that plasma VIII-vWF factor levels are about 25% higher in non-O-type individuals than in patients with type O blood type.
previously identified elevated levels of the VIII-vWF factor as a risk factor for coronary heart disease.
this, it will be especially important for people with non-O-type blood to maintain a healthy heart lifestyle that includes improving cholesterol levels, quitting smoking, controlling high blood pressure and diabetes, exercise, maintaining a healthy weight, limiting alcohol consumption, and dealing with stress.
risk of stomach cancer in people with type A blood has many factors associated with a higher risk of cancer, so it is sometimes difficult to know which factors are dominant.
However, studies have confirmed that people with different ABO blood types have different risks of cancer, people with type A blood have an increased risk of stomach cancer, and people with non-O blood type (A, B, AB) have an increased risk of pancreatic cancer.
a cohort study from Taiwan included 339,432 healthy people with laboratory-based blood types.
The study, after adjusting age, sex, education level, smoking, alcohol consumption, physical activity and body mass index, showed a significant correlation between type A blood and gastric cancer risk and mortality compared to type O blood, and non-O type blood was associated with an increased risk of pancreatic cancer.
, AB blood was inversely associated with the risk of kidney cancer compared to type O.
HRs by ABO blood type for overall and specific eganological cancer incidence, partial screenshots of ABO blood types and cancer risk-A cohort study of 339,432 subjects in Taiwan.doi: 10.1016/j .canep.2014.12.006 The findings from the American Journal of Epidemiology also suggest that if the blood type is AB, the risk of stomach cancer is about 26% higher than that of type B or O, and 20% higher if it is type A.
other cancers, researchers at the Institute of Cancer Research at the Chinese Academy of Sciences have even confirmed that ABO blood type is an independent prognosis for ovarian cancer patients.
study analyzed the relationship between ABO blood type and clinical characteristics in ovarian cancer patients and found that ovarian cancer patients with type B/AB blood had poor OS, especially in patients with FIGO I, stage IV, and menopause.
and multivariate analysis shows that this association is independent.
doi:10.7150/jca.36236 Again, although blood type cannot be changed, there are ways to reduce the risk of cancer, such as focusing on a healthy diet, eating more fruits, vegetables, whole grains, fish, etc., and exercise regularly to avoid smoking.
avoiding Helicobacterrobacteria infections is an important measure to prevent stomach cancer, and some experts believe that people with type A blood may over-react to the bacteria' immunity, thereby increasing the risk of cancer.
have a low risk of Alzheimer's disease in people with type O blood are associated with reduced brain function and memory.
people with type A, B and AB blood were 82 percent more likely to have cognitive and memory problems that could lead to dementia than people with type O blood.
by researchers at the University of Sheffield in The United States has revealed the role of blood types in the development of the nervous system.
study, which performed magnetic resonance imaging (MRI) scans of the heads of 189 healthy volunteers and calculated the volume of gray mass in the brain, found that people with type O blood had more gray mass in their brains (more gray mass in the back of the microcephaly), and people with type A, B or AB blood had smaller gray mass volumes in the tizoe and edge areas of the brain, including the left sea mass.
these findings suggest that smaller gray mass volumes are associated with non-O-type blood.
the grayscaness in the brain tends to decrease with age, leading to an increased risk of diseases such as Alzheimer's disease.
the left sea mass was one of the first parts of the brain to be destroyed by Alzheimer's disease.
smaller gray matter volume associated with non-O-type blood 'O' blood type is associated with with larger grey-matter volumes in the cerebellum. doi:10.1016/j.brainresbull.2015.05.005 The study suggests that blood type is likely to affect the development of the nervous system and further exploration is needed in the future.
in our daily routine, we still need to maintain cognitive strength by exercising regularly, avoiding stress, and getting enough regular sleep.
so much, we all know that there are often many factors that affect disease, blood types are just one of them, and there may be contradictions in different studies.
may eventually return to a hard indicator, life expectancy.
the study has logically expanded to look at the potential association between ABO blood types and life expectancy, but in the mid-twentieth century, studies began to try to explain differences in life expectancy between individuals of different blood types.
people of different blood types really live different lives? Which blood type lives longer? Is blood type related to longevity? The first study in 1961 found that 125 healthy older men (65-89 years old) had more type A blood.
, a study of 50 residents over the age of 90 found no correlation between ABO blood type and life expectancy.
study of German doctors over the age of 75, type O blood appeared to be associated with longer life expectancy.
two studies of centenarians found to be contradictory.
among 269 Japanese centenarians, a higher proportion of type B blood was observed (29.4 per cent).
contrary, U.S. studies have concluded that type B is not so much associated with longevity as a sign of early death.
as far as current research is speaking, the link between blood type and life expectancy is inconclusive.
these differences may be explained in several ways.
, for example, any identified associations may be population- or location-specific.
, different conclusions may be influenced by methodological differences, including potential pitfalls prevalent in research in this area.
sampling error and racial or ethnic stratified may also be the reasons why different research groups reach different conclusions.
, race and ethnic factors also lead to differences in the distribution of the ABO gene by as much as 5 to 20 percent among the population in the same country or even in the same city.
, sampling errors can cause differences of up to 4% between samples from 1,000 individuals.
if the link between blood type and life expectancy is to be clarified, it is important to clarify the mechanisms that cause this interaction, in part because any possible changes to the negative impact on longevity can be potentially assessed.
However, since the ABO population is currently an imm changed human trait, any study of any association between ABO blood type and life expectancy may boil down to the fact that it is "quite interesting" rather than "clinically realistic".
that the "blood type diet" has been overturned, although there are many studies on blood type and health links, it may be too early to guide clinical guidance.
the so-called "blood type diet" has spread widely.
"blood type diet" recommends that people with type A blood focus on plant-based diets, while people with type O blood recommend meat-based.
claim was rejected in a recent study published in the Journal of Nutrition and Diete, and its main findings were published November 30 in the Journal of the American Medical Association, Network Open.
the new study was based on a randomized controlled trial that randomly assigned overweight participants without a history of diabetes to the intervention group or control group on a 1:1 scale.
group followed a low-fat, plant-based diet.
control group did not make dietary changes and were observed for 16 weeks.
found that a plant-based diet accelerated metabolism and increased calorie consumption after meals by an average of 18.7 percent over the control group.
Clinical changes in overweight people who received plant-based interventions in a randomized clinical trial, by blood type, Blod Type Is Not Associated with Changes in Cardiometabolic Outcomes in Response to a Plant-Based-Dietary Intervention.DOI: Taking into account the potential link between blood type and diet, the researchers took additional steps to conduct a second analysis in the intervention group of participants in the 16-week randomized clinical trial.
analyzed whether plant-based dietary interventions were associated with weight, lipids, and blood sugar control with ABO blood type, and found no difference.
That is, a plant-based diet is good for all blood types, all of which also benefit from a vegetarian diet based on eating fruits and vegetables, legumes, and whole grains, especially for overweight adults, and there is no evidence that a meaty diet is good for people of a certain blood type.
All in all, the link between blood type and health is becoming clearer in increasingly mature studies, but there are many contradictions in the study of the link to real life expectancy, and it may take some time to solve these mysteries.
but it's safe to say that no matter what health risks blood type indicates, paying more attention to healthy eating and exercising in our daily lives will always bring benefits to reducing the risk of various diseases.
