Acute gastrointestinal problems are no longer very common at this age. The child begins to understand which foods it cannot tolerate and learns to avoid them. Any persisting food allergy is thus more likely to express itself in skin eruptions or airways obstruction than in vomiting and diarrhea. However, caution should still be taken when introducing new foods in the diet of a child with a history of food allergy.

Age 7-15

IgE-mediated gastrointestinal reactions are not very common, but there are children who never grow out of their food allergy. Typically offending food allergens seen in school children and adolescents are fish, shellfish, tree nuts and peanuts, but also fruits and vegetables causing itching and swelling in the mouth. The oral allergy syndrome (OAS) is highly associated with pollen allergy. Therapeutically, the situation at this age is no worse than before, but psychologically it is more complex. The normal adolescence issues of striving for independence from the family become entangled with parental concern for the child's health.
