The underlying hypothesis of blood type diets is that people with different blood types digest lectins differently, and that if people eat food that is not compatible with their blood type, they will experience many health problems. On the other hand, if a person eats food that is compatible, they will be healthier.

Blood transfusion immunological reaction occurs when the receiver of a blood transfusion has antibodies against the donor blood cells. The destruction of red blood cells releases free hemoglobin into the bloodstream, which can have fatal consequences. Landsteiner's work made it possible to determine blood group and allowed a way for blood transfusions to be carried out much more safely. For this discovery he was awarded the Nobel Prize in Physiology and Medicine in 1930, and many other blood groups have been discovered since. George Washington Crile is credited with performing the first surgery using a direct blood transfusion in 1906 at St.
