Allergy is a response of the defense system to certain substances termed allergens, which usually are harmless and does not bother most other people. Allergy erupts when your body reacts to something it is abnormally sensitive to. When you come in contact with any allergen your body will defend itself by releasing substances known as antibodies. The ensuing reaction between antibodies and allergens trigger the release of 'Histamine' and other chemicals, which cause the symptoms of allergy.
Almost any food can bring on an allergic response. The commonest being milk, cheese, eggs, nuts, fish and shell-fish, wheat and flour, chocolates and artificial colourants. Other factors: You can be allergic to soaps, perfumes, detergents, insect bites, antibiotics, cosmetics and jewellery.
