5. Health risks
According to scientists, there are ways in which blood biochemistry determines our health. Even though the influence of blood types on our health is still under research, there are certain theories on health risks and benefits for people with different blood types. It is considered, in particular, that people with O blood type can be more susceptible to some bacterial and viral infections than other blood groups, including severe ones like plague, cholera, mumps, and tuberculosis. Some studies also show that blood type O individuals have a 35% higher incidence of duodenal ulcers compared to people with A, B, and AB blood types.
6. Health benefits
People with type O blood have the lowest risk of developing coronary heart disease compared to people with A, B, and AB blood types. Studies show that non-O blood type individuals have a 25% higher risk of developing pancreatic cancer than people with O blood type. What is more, is people with blood type O have a lower risk of developing circulatory diseases and cognitive disorders. However, keeping a healthy lifestyle and managing health risk factors is crucial for avoiding diseases, no matter what blood type you have.
7. Type O blood and personality
The influence of blood type on people’s traits of character is rather debatable, but this theory is very popular in some countries, in particular, Japan. TV shows, newspapers and magazines often publish blood type horoscopes and romantic compatibility charts, while Japanese manga, anime, and video games mention characters’ blood types. The Japanese believe that people with O blood type are generous, passionate, sociable and financially successful and that the best romantic match is found between type O and type A people.
