Nutty Words to Watch For

  • Artificial nuts
  • Nuts of any sort
  • Nut butters and oils
  • Peanut products, such as peanut flour, peanut starch, and peanut oil (including foods fried in it, unless the oil is purified)

Where Peanuts Hide

  • Many processed foods like ice cream, snack foods, biscuits, baked goods, and candy
  • Ethnic food including African, Chinese, Indonesian, Mexican, Thai, and Vietnamese cuisine, to name a few
  • Many flavorings, thickeners, and sauces. Even artificial nuts -- used on sundaes
  • Roasted and fried foods -- like roasted chicken -- may have peanut oil in them

Where Tree Nuts Hide

Like peanuts, tree nuts can be hidden in many foods. They may even be in non-food products like lotions (shea butter, for example) and shampoos.

Be especially careful with:

  • Sauces (like Worcestershire sauce, barbecue sauce, or pesto, which contains pine nuts)
  • Natural flavorings and extracts
  • Salad dressing, and gravies

See the list above under peanut allergies for other places tree nuts may be found.
