In Taiwan and South Korea, people will often ask you what your blood type is. Just like star signs in the U.S., it’s believed that your blood type can say something about your personality. While that may be up for debate, studies have found that your blood type can say something about your health risks. Here are some of the key things your blood type can affect:
People with the AB blood type are, according to a recent study from the University of Vermont, 82 percent more likely to develop memory and thinking problems that eventually turn into dementia. Dr. Cushman, the head of the study, said that vascular issues can “contribute to memory problems.”
2. Heart disease
Your blood type can have an impact on diseases such as heart attack, stroke and thrombosis. A study from the Harvard School of Public Health found that non-O blood groups have at least a 60 percent higher chance of developing dangerous blood clots, and an increased risk of coronary heart disease. However, like in most of these situations, lifestyle and prescribed medications can have a much bigger impact on risk, and tip the probability of something going wrong in the opposite direction.
3. Gastrointestinal conditions
It seems that people with blood type A are more likely to get gastric cancer, and people with blood type O are more likely than others to develop a peptic ulcer. Gustaf Edgren, associate professor of epidemiology at the Karolinska Institute in Sweden, says that different blood types have different susceptibilities to bacterial infections, and these two conditions are associated with a bacteria called H. pylori. However, he also stresses that the risk difference is too small to be of any serious consequence, and that the most important thing is to avoid smoking and excessive alcohol consumption, while eating a healthy diet.
The O blood type has been linked with a reduced risk of getting a range of cancer types, including colorectal, pancreatic and stomach cancer.
A 2015 study of 82,000 women found that blood types A and B were more likely to develop type 2 diabetes.
People with type O blood come out the winners again here, as they have some protection from the worst types of malaria. Researchers have found that this is because the type of protein secreted by the mosquito tends to bind better with blood cells that are type A rather than type O.
7. Vegetarian and meat-based diets
There is a lot of debate over if a diet aligned with your blood type has any scientific basis or not. The author of “Right 4 Your Type” argued that people process their food differently depending on their blood type, but other scientists have suggested the theory lacks credibility. If you are interested, the theory contends that type A people are better off as vegetarians, and type O are set up to be meat eaters.
