A food allergy is an abnormal immune response to food, with symptoms ranging from mild to severe (anaphylaxis).
Allergies occur when immunoglobulin E (IgE), part of the body's immune system, binds to food molecules. This usually occurs with protein in the food, and triggers the release of chemicals such as histamine.
In the developed world about 4% to 8% of people have at least one food allergy. They are more common in children than adults and appear to be increasing in frequency. Some allergies more commonly develop early in life.
