Tree nut allergy

What is a tree nut allergy?

Tree nuts are true nuts (not peanuts), so include brazil nuts, hazelnuts, almonds, walnuts, cashews, pistachios, pecans, chestnuts, pine nuts, and a number of other nuts. Although peanuts are not in this group (biologically, peanuts are legumes, whereas true nuts are fruits), the allergens in tree nuts and peanuts are very similar, which is why a lot of people who have a tree nut allergy also have a peanut allergy, and vice versa. 12 % of people who are allergic to one type of nut are also allergic to other types of nut as well. The most common cross reaction is between walnuts and pecan nuts, and between cashews and pistachios.

Tree nut allergies are common in both children and adults. Approximately 90 % of children who have a tree nut allergy will not outgrow it.

Although coconuts may sometimes be classified as tree nuts (for the purposes of food labelling), allergic reactions to coconuts are extremely rare.
