From a medical perspective food allergy is an immunoglobulin (Ig)E- or non-IgE-mediated immune response to food protein. This small review will look at the IgE mediated food represented by immediate hypersensitivity (Gell-Coombs Type I), which can include anaphylaxis and can be life-threatening.

Food or environmental exposures that result in non-IgE-mediated reactions are thought to be cell mediated (allergic eosinophilic esophagitis/gastroenteritis, food protein-induced proctocolitis, food protein-induced enterocolitis syndrome, food protein-induced enteropathy; including coeliac disease).
