Quizplus · Accepted Answer

Anaphylactic reactions to food usually occur within the first 2 hours after exposure.These are usually IgE-mediated allergies.Chronic and relapsing forms of food allergies may take more than 2 hours because they tend to be either a mix of IgE- and cell-mediated reactions or nonIgE- and cell-mediated reactions.A food-dependent, exercise-induced anaphylaxis is a particular type of physical allergy that occurs within 2 hours of rigorous activity after eating a specific food that is normally tolerated.
