Common Food Allergies

In adults, the foods that most often cause allergic reactions include:
Shellfish such as shrimp, crayfish, lobster, and crab Peanuts Tree nuts such as walnuts Fish Eggs
The most common foods that cause problems in children are: Eggs Milk Peanuts Tree nuts
Peanuts and tree nuts are the leading causes of the potentially deadly food allergy reaction called anaphylaxis.
Adults usually keep their allergies for life, but children sometimes outgrow them. Children are more likely to outgrow allergies to milk, egg, or soy, however, than allergies to peanuts. The foods to which adults or children usually react are those foods they eat often. In Japan, for example, rice allergy is frequent. In Scandinavia, codfish allergy is common.
