But the emergence of alpha-gal syndrome, which causes some people to develop a long-term allergy to red meat and other animal food products, is very real.

Sep 15, 2022 Alpha-gal syndrome is an unconventional food allergy, characterized by IgE-mediated hypersensitivity responses to the glycan galactose-alpha-1,3-galactose (alpha-gal) and not to a food-protein. In this review, we discuss how alpha-gal syndrome reframes our current conception of the mechanisms of pathogenesis of food allergy.
