No Bacon For Any Blood Type?
Why is pork an avoid for all blood types?
Pigs (like most non-humans) induce xenoreactive antibodies which in turn upregulate our own anti-ABO antibodies (the isohemagglutinins). This antigen in pigs, galactose alpha-(1-3) galactose, is apparently the target for these antibodies (which all adult humans have.) Though found in many mammals, pig xenoreactive antigens are probably more potent than most, since virtually every human carries antibodies to pork. Indeed, in every patient on whom I've ever tested blood group antibody levels, and who was a big pork consumer, the levels of antibody titer were always elevated.
