Do nut allergies ever go away?
Do nut allergies ever go away? About 80 percent of people with egg, milk and wheat allergies outgrow them, usually by age 16. About 20 to 25 percent of children with peanut allergies outgrow them, and about 80 percent who outgrow them will do so by age 8. Allergies to tree nuts, fish and shellfish may be tougher to outgrow and are often lifelong.
Can you build up an immunity to nut allergies?
The natural history of food allergy indicates that such allergy can be outgrown and therefore shows that it is possible to acquire tolerance after sensitization has occurred. Unfortunately, natural tolerance is infrequent for antigens such as peanut, tree nuts, fish, or shellfish.
