Find out how to help your child manage an allergy to tree nuts such as almonds, pecans, cashews or hazelnuts.

Key points

  • Tree nuts include almonds, Brazil nuts, cashews, pistachios, walnuts, hazelnuts and pecans. Peanuts are treated as a separate allergen.
  • A tree nut allergy can be severe and life-long. Even if your child is allergic to only one type of tree nut, they may need to avoid all others due to the risk of cross-contamination.
  • Many different products contain tree nuts, including baked goods, curries, egg rolls, cereals, crackers, dressings and nut butters.
  • To prevent an allergic reaction, always read food product labels, avoid foods if you are not sure of the ingredients and avoid using utensils or containers that might have come in contact with tree nuts.
  • If your child's diet is limited because of a tree nut allergy, a registered dietitian can offer advice on getting a balanced diet.
