When Do Food Allergies Typically Develop?
Food allergy most commonly starts in childhood. Not all food-related reactions are food allergy and, in fact, most rashes in childhood are not related to food. It often takes a detailed history and specific allergy testing to reach the diagnosis of food allergy. While some individuals may classify their food allergy as mild or severe, it is more important to know that any allergic reaction to food can cause a life-threatening condition called anaphylaxis, even if the reaction in the past was mild.
