Tree nut allergies are common in both children and adults. Approximately 9% of children with a tree nut allergy eventually outgrow their tree nut allergy. In an adult, “outgrowing” or “reversing” a tree nut allergy is not common.
Tree nuts can cause severe, potentially fatal, allergic reactions. To prevent an allergic reaction, strict avoidance of tree nuts is essential. A person with an allergy to one type of tree nut has a greater chance of also being allergic to other tree nuts. Therefore, many experts advise patients with an allergy to a tree nut to avoid all tree nuts. Your allergist can help you with personalized recommendations for your care. The Food Allergy Research & Education (FARE) website is also an excellent resource.
