Understanding Hidden Tree Nut Ingredients
Tree nuts are commonly used in a variety of processed foods, baked goods, and even personal care products. Reading ingredient labels and being aware of potential sources of tree nuts is essential for individuals with tree nut allergies.
Common Foods That May Contain Hidden Tree Nuts
Processed Foods
- Granola bars, protein bars, snack mixes
- Breakfast cereals and flavored oatmeal
- Crackers and packaged cookies
- Ice creams and frozen desserts
- Nut-based energy drinks and meal replacements
- Deli meats such as mortadella (often contains pistachios)
Baked Goods & Desserts
- Cakes, muffins, pastries, and doughnuts
- Brownies and cookies (especially with nut extracts or nut flours)
- Pies and tarts (e.g., pecan pie, almond croissants)
- Bread and rolls (some contain walnut or almond flour)
- Whipped toppings and dessert garnishes
Chocolate & Confectionery
- Chocolates with fillings (e.g., praline, nougat, hazelnut paste)
- Nut-flavored candy bars (e.g., almond, hazelnut, cashew-based treats)
- Marzipan, almond paste and frangipane (almond) in holiday treats and pastries; gianduja (hazelnut-chocolate paste)

Nut Butter & Dairy Alternatives
- Almond, cashew, and hazelnut butter
- Almond milk, cashew milk, and macadamia milk
- Cashew-based cheese and yogurt alternatives

Sauces & Condiments
- Pesto (traditionally made with pine nuts, but many versions use cashews, walnuts, almonds or other nuts)
- Salad dressings with nut oils or nut-based thickeners
- Nut-flavored spreads and dips (e.g., nut-based hummus variations). Note: tahini is sesame, not a tree nut — sesame is a separate major allergen.
- Nut-based barbecue sauces or gravies
Cooking Oils & Thickeners
- Almond oil, walnut oil, hazelnut oil (commonly used in gourmet cooking)
- Nut-based thickeners in soups and sauces
- Cold-pressed or unrefined nut oils used in specialty foods
Alcoholic Beverages & Flavored Drinks
- Amaretto (almond-based liqueur)
- Hazelnut coffee syrups and flavored drinks
- Nut-infused spirits or craft cocktails
- Some specialty teas and herbal drinks
- Alcoholic drinks are regulated by the TTB rather than the FDA, so allergen labeling on them is voluntary.
Personal Care Products
- Lotions, soaps, shampoos and massage oils may contain nut oils. Cosmetics list ingredients by botanical (INCI) names, for example Prunus amygdalus dulcis (sweet almond) oil, Corylus avellana (hazelnut) seed oil, Juglans regia (walnut) seed oil and Macadamia integrifolia or Macadamia ternifolia (macadamia) seed oil.
