Tree Nut Allergy

Tree nut allergies are one of the most common food allergies. Allergy symptoms can range from mild (e.g. a rash) to severe (e.g. anaphylaxis, a potentially life-threatening allergic reaction). In cases of allergic reactions, seek medical help immediately.

If you have an allergy to one of the members of the tree nut family, you are more likely to have allergies to other types of tree nuts. Those with tree nut allergies may be advised to avoid all nuts and also peanuts, since tree nuts are commonly processed with the same equipment as peanuts, peanut butters, seeds, and seed butters.

If you are allergic to tree nuts, always read ingredient labels to see if products contain tree nuts or were processed with the same equipment as tree nuts.
