The latter is classified into A, B or O according to the presence of these proteins. In this article you will discover why people of blood group O are so special. Generally, blood type O + is the largest and accounts for 38% of human beings, while group O – concerns only 7% of people in the world. What makes people to O blood group so special? Unlike the rest of the blood group, blood group O is not a carrier of antigens. The latter constitute a foreign substance to the organism capable of triggering an immune response that is intended to eliminate. Moreover, people of blood group O – are universal donors, but they can only receive blood that their own group. Recent research has proven that the blood group had a very important role on the health of the individual and could warn of several diseases. However, scientists do not all agree on the subject.
