If your kids suffer from chronic runny noses and sore throats, it might be time to dump the dairy. According to the American Academy of Allergy, Asthma and Immunology, cow’s milk is the number one-cause of food allergies in children. According to the former director of pediatrics at Johns Hopkins University, Dr. Frank Oski, there is evidence to indicate that up to half of U.S. children have some allergic reaction to milk. For these kids (and for adults who are allergic to dairy foods), milk is a mucus maker and can lead to persistent problems such as chronic coughs and sinus infections, asthma, and ear infections.
