What foods are most likely to cause allergic reactions?

Adults

In adults, the most common foods to cause allergic reactions include: shellfish such as shrimp, crayfish, lobster, and crab; peanuts (a legume that is one of the chief foods to cause severe anaphylaxis, a sudden drop in blood pressure that can be fatal if not treated quickly); tree nuts such as walnuts; fish; wheat; soy and eggs.

Children

In children, the pattern is somewhat different. The most common food allergens that cause problems in children are eggs, milk, and peanuts. Adults usually don't lose their allergies, but children can sometimes outgrow them. Children are more likely to outgrow allergies to milk or soy than allergies to peanuts, fish, or shrimp.

Foods Eaten Often

The foods that adults or children react to are those foods they eat often. In Japan, for example, rice allergies are more common. In Scandinavia, codfish allergies are more common.
