What is a food allergy?

Food allergy is an immune-system–mediated reaction to specific proteins in foods. When someone who is sensitized encounters the trigger protein, the immune system releases substances like histamine, which can cause symptoms ranging from hives and swelling to vomiting or more severe reactions such as anaphylaxis. This immune involvement and protein-specific trigger differentiate it from other issues like lactose intolerance (a non-immune enzyme deficiency) or reactions caused by toxins from spoiled foods. So, describing a food allergy as an immune response to particular food proteins best captures the concept.
