- Peanut allergy is one of the most common food allergies, and it is considered a priority food allergen by Health Canada. Priority food allergens are the foods that cause the majority of allergic reactions.
- Peanuts are a member of the legume family, and not related to tree nuts. A person can be allergic to peanuts and not be allergic to tree nuts, or they can be allergic to both.
- Lupin (or lupine) is an ingredient that is increasingly being used in foods, especially gluten-free products. It is a legume belonging to the same plant family as peanuts, and some people are allergic to both. It is recommended for anyone with a peanut allergy to avoid products containing lupin until they have consulted with their allergist.
- It was once considered that all peanut allergies were lifelong. However, some studies have shown that some children may outgrow their peanut allergy. If your child has peanut allergy, consult with your allergist before reintroducing peanut products.
- Many international cuisines use peanuts in food, including, Indonesian (e.g., satays), Thai (e.g., curries), Vietnamese (e.g. crushed peanut as a topping, spring rolls), Indian (e.g., certain curries), and Chinese (e.g. egg rolls, certain sauces).
Allergic reactions to peanut
If you have an allergy to peanut, keep an epinephrine auto-injector (e.g., EpiPen®, ALLERJECT®) with you at all times. Epinephrine is the first-line treatment for severe allergic reactions (anaphylaxis).
Be allergy-aware: How to avoid peanut
- Read ingredient labels every time you buy or eat a product. If the label indicates that a product “Contains” or “may contain” peanut, do not eat it. If you do not recognize an ingredient, if there is no ingredient list available, or if you don’t understand the language written on the packaging, avoid the product.
- Do the Triple Check and read the label:
- Once at the store before buying it.
- Once when you get home and put it away.
- Again before you serve or eat the product.
- Always carry your epinephrine auto-injector. It’s recommend that if you do not have your auto-injector with you, that you do not eat.
- Check with manufacturers directly if you are not sure if a product is safe for you.
- Be careful when buying products from abroad since labelling rules differ from country to country.
- Watch for cross-contamination, which is when a small amount of a food allergen (e.g., peanut) gets into another food accidentally, or when it’s present in saliva, on a surface, or on an object. This small amount of an allergen could cause an allergic reaction.

Emerging Allergen Reporting Tool
If your child has had a reaction in the last 12 months to a food other than a priority allergen, participate in an important research survey. Your participation will help researchers, and advocacy groups like ours, better understand emerging allergens.
