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.
