The rarest blood type

You’ve probably heard that AB is the rarest blood type. However, this is only true if you consider the eight combinations: A, B, O, and D+ or D-. According to Stanford University School of Medicine, about 0.6% of the population has AB- blood.

There are countless different antigens. Combining all of these factors, we find people with extremely rare blood types. For example, a man named Thomas is so special that he does not possess any of the Rhesus antigens. He is one of 40 people in the world who are Rh-negative and can donate blood to anyone with the rare Rh type. However, when he needs blood, Thomas can only receive Rh-negative blood. Besides him, there are only 5 such people in the world.

Defines human character

Blood types are particularly important in Japan. The concept of the ABO system was first proposed in the 20th century. Shortly thereafter, in 1927, Tokyo professor Takeji Furukawa published articles arguing that blood types predicted personality. His arguments were quickly forgotten, but were revived by author and journalist Masahiko Nomi in the 1970s.

Until now, Japanese people are still very interested in blood type, even based on it to evaluate whether boyfriend or girlfriend is compatible with them. However, most of the research on this issue is not accurate enough to be trusted.

Nutritional regimen

In 1996, American author Peter J. D'Adamo published a book called Eat Right According to Your Blood Type, which caused a huge stir. According to him, people with blood type O should eat protein-rich foods such as red meat, poultry, and fish, while people with blood type A should do the opposite and avoid all types of meat. However, the scientific evidence D'Adamo presented was less convincing than the argument that blood type determines personality.

Health risks

Scientists have proven that blood type affects human health. People with blood type O have more clotting factors, which makes them twice as likely to get venous thrombosis as people with other blood types. Recently, a study showed that other blood types have a higher risk of cardiovascular disease and cancer than people with blood type O.
