The ancients believed that human natures are linked to his blood type, and although this has not been scientifically proven, several scientific studies have confirmed the existence of links between blood type and a close relationship with the human ability not to contract some diseases.
After the discovery of the types of human blood types nearly a hundred years ago, myths about human blood reappeared. The Japanese believe today that human natures and morals can be read through blood type. While applying for a job, blood type is often required to know whether a person can take high positions at work or not, according to the dw website.
But modern science has not found any explanation or direct link between the morals and natures of man and his blood type. Talking about the effect of blood on human nature remains myths without scientific evidence.
As for the effect of blood type on the possibility of human disease, it has scientific evidence, says German Professor Markus Lerch of the University of Greifswald. There are four types of blood, namely “A”, “B”, “IB” and “O”. It is not possible for a person to determine the blood type that suits him, but rather that he is born with a certain blood type.
In the blood there are red and white blood cells, in addition to nutrients and oxygen. On the surface of red blood cells there are different types of “antigens” proteins. These “antigens” stimulate the immune response and produce antibodies in the body against diseases. Its types and quantities vary according to the blood type in the body, and its work was first discovered by the Austrian doctor Karl Landsteiner in the year 1900.
The system and appearance of bacteria is similar to “antigens”, and bacteria choose the appropriate blood cells for them, as Professor Lerch explains. Therefore, a person is more likely to be exposed to certain diseases, according to his blood type. People with blood types A, B and IB are immune to the plague.
As for those with blood type B, they suffer from a high percentage of the enzyme “lipase”, which performs a major task in the process of digestion and processing dietary fats, and therefore they suffer from pancreatic diseases by about two and a half times more than people with other blood types.
As for people with type “IB”, they suffer from a higher incidence of memory loss, and it is 80 percent higher than those with blood type “O”.
