Vitamin A in cattle fodder is potentially protecting against cow’s milk allergy

Infants can develop an allergy to cow’s milk that usually subsides by adulthood but may increase risk for developing other allergic diseases. The allergic reaction can, however, be prevented by two components of cow’s milk interacting together, as researchers now describe. Loading of vitamin A metabolite retinoic acid to the important milk protein beta-lactoglobulin in cow’s milk can prevent allergic reaction against the protein.
