An allergy is a reaction involving the body’s immune system.  Food sensitivities or intolerances may cause symptom but do not provoke a true allergic response by the body’s immune system.

Allergic reactions may be quite severe and usually occur in young children, whereas food sensitivity may arise (and disappear) at any stage of life.

Symptoms of food allergy include swelling of the throat, diarrhoea and vomiting, asthma or eczema.  Many children grow out of their allergies when their digestive system matures.

Foods which commonly cause allergic responses include milk, eggs (especially the white), fish, shellfish, wheat or other cereals, nuts, peanuts, chocolate, tomatoes and some fruits.
