We also were not sure where families get information or guidance on this topic. Continue reading

Red meat allergy is thought to be caused by tick bites which expose humans to alpha-gal, however other factors that contribute to disease risk are not well described. Alpha-gal looks a lot like the B antigen, which is one of the factors that determines blood type. So we wondered whether people with blood types B or AB are protected from getting red meat allergy. We were amazed when we found that patients who make the B antigen (blood types B or AB) are 5 times less likely to have red meat allergy than patients who do not make the B antigen (blood types O or A).  Continue reading
