Food allergy is an adverse reaction due to a specific immune response
occurring reproducibly upon exposure to certain foods. It occurs minutes
to hours after food consumption.
Immunological mechanisms can be IgE mediated, non-IgE mediated or mixed IgE and non-IgE mediated.
It may be life-threatening and is the most common cause of anaphylaxis in children.
It should be differentiated from food intolerance in which adverse
reactions from exposure to food arise from non-immunological mechanisms.
