Tree Nut Allergies

  • Overview

    A tree nut allergy is an abnormal response of the body to the proteins found in tree nuts.

  • In-Depth

    Which foods and ingredients must a tree-nut-allergic person watch out for?

    Avoid foods with any of the following ingredients:

    • Almonds
    • Brazil nuts
    • Cashews
    • Chestnuts
    • Filberts/hazelnuts
    • Gianduja (a creamy mixture of chocolate and chopped toasted nuts found in premium or imported chocolate)
    • Hickorynuts
    • Macadamia nuts
    • Marzipan/almond paste
    • Nougat
    • Nu-Nuts (artificial nuts are peanuts that have been deflavored and reflavored with a nut such as pecan or walnut)
    • Nut butters (cashew butter, almond butter)
    • Nut oil
    • Nut paste (almond paste)
    • Pecans
    • Pine nuts (pignolia, pinion)
    • Pistachios
    • Walnuts
    • Natural extracts, such as pure almond extract. (Imitation or artificially flavored extracts are often safe.)

    Anything else to consider?

    • Ethnic foods, commercially prepared baked goods and candy can often be cross-contaminated with nuts as nuts are frequently used in these types of foods.
    • Tree nuts are being added to an increasing variety of foods, such as barbecue sauce, cereal, crackers and ice cream.
