What are the most common foods that people are allergic to?
A consumer resource from the FDA, Food Allergies: What You Need to Know, lists the foods that most commonly cause allergies as milk, eggs, fish, crab, lobster, shrimp, almonds and other tree nuts, and peanuts. Peanuts are one of the chief foods responsible for severe anaphylaxis.
Children will typically outgrow their allergies to milk, egg, soy and wheat, but will not typically outgrow their allergies to peanuts, tree nuts, fish and shrimp. In contrast, adults will not typically outgrow any of their allergies.
