Allergic reactions to foods in children.

Food reactions in children may be divided into two types: immediate and delayed. Cow's milk, egg and peanuts are the most commonly implicated foods. Immediate food reactions are associated with the presence of specific IgE antibodies to the food concerned, although detection of specific IgE is of no help in the diagnosis of delayed reactions. The only way to definitely confirm a food reaction is by elimination and rechallenge. Food reactions can be expected to improve naturally with time.
