Tree nut allergy list for U.S. labels
A tree nut allergy list is not just one ingredient to memorize. Tree nuts are a group, and U.S. allergen labeling rules treat them as a major allergen category while also requiring the specific type of tree nut to be identified when it is used as an ingredient in most FDA-regulated packaged foods.
That specific-name rule matters because people do not always avoid the same nuts. One person may be told to avoid all tree nuts, while another may have guidance about particular nuts. This guide is educational and cannot decide what you personally should eat; use it to read labels more consistently, then follow the package label, the manufacturer’s information, and your healthcare professional or allergy care plan.
Tree nuts can appear as whole nuts, pieces, flours, pastes, oils, extracts, fillings, toppings, and flavorings. They also show up in foods that do not look like a bowl of nuts, including baked goods, chocolates, sauces, cereals, and snack mixes. If you are building a household routine, it helps to pair this tree-nut-specific guide with a broader routine for how to read food labels for allergies.
What counts as a tree nut on U.S. labels
On U.S. FDA-regulated packaged foods, tree nuts are one of the nine major allergens. When a tree nut is an ingredient, the label must identify the specific nut, such as almond, walnut, or cashew. The nut may be named in the ingredient list, in parentheses after an ingredient, or in a Contains statement, such as “Contains: Almonds.”
The FDA updated its tree nut guidance in January 2025 and removed coconut from its list of tree nuts for major allergen labeling. That means coconut is not declared as a major allergen tree nut under the FDA’s current guidance. This does not answer every personal diet question about coconut, so anyone with a specific concern should ask their healthcare professional and verify products with the manufacturer.
A practical tree nuts list for label reading includes the nuts below. Chestnut remains on the FDA tree nut list, even though it is less common in many U.S. packaged foods than almonds or cashews.
- Almond
- Brazil nut
- Cashew
- Chestnut
- Hazelnut or filbert
- Macadamia nut
- Pecan
- Pine nut or pignoli
- Pistachio
- Walnut
Is peanut a tree nut?
No. Peanut is not a tree nut; it is a legume. In U.S. allergen labeling, peanuts and tree nuts are separate major allergen categories. A label may say “Contains: Peanuts,” “Contains: Tree Nuts (Almonds),” or both, depending on the ingredients in that product.
That separation is helpful, but it does not make shopping automatic. Peanut and tree nut products are often sold near each other, combined in mixed-nut products, or handled in the same facilities. If peanut also matters in your household, use a separate peanut ingredient guide instead of assuming tree nut rules cover peanut terms.
Be especially careful with wording such as “nut butter,” “nut flour,” or “mixed nuts.” Sometimes “nut” is used casually on front labels or menus, while the ingredient list gives the exact nut. The ingredient list and allergen statement are the places to confirm what is actually in the packaged food.
- Peanut is a legume
- Tree nuts are a separate major allergen category
- A product can contain peanuts, tree nuts, or both
- Mixed-nut wording needs a full label check
- Peanut cross-contact and tree nut cross-contact are separate questions
Nut ingredient names to watch for
Many labels simply use the nut’s common name: almond, cashew, pecan, walnut, pistachio, hazelnut, Brazil nut, macadamia nut, pine nut, or chestnut. Other labels use culinary words that point to a nut ingredient. If a major-allergen tree nut is the source, the label should identify the specific nut somewhere on the package, but recognizing these words helps you slow down and verify the declaration.
Some terms are strongly tied to specific nuts. Marzipan is usually almond-based. Gianduja is a chocolate-hazelnut mixture. Praline may involve pecans, almonds, hazelnuts, or other nuts depending on the product and recipe. Nougat can contain nuts or be paired with nut pieces in candy bars and confections. These words should not be treated as a complete answer by themselves; they are signals to read the full ingredient list and allergen information.
Nut oils and extracts deserve a careful read. Highly refined oils from major allergens are exempt from major allergen labeling requirements, but less refined, cold-pressed, expeller-pressed, gourmet, roasted, or flavored nut oils may still matter and should be evaluated from the exact label and manufacturer information. Natural nut extracts and flavorings may use small amounts but can still be nut-derived ingredients.
- Almond flour, almond meal, almond paste
- Marzipan
- Praline
- Nougat with nuts
- Gianduja
- Hazelnut spread
- Nut paste or nut filling
- Nut butter or mixed nut butter
- Nut pieces, chopped nuts, nut topping
- Walnut oil, almond oil, hazelnut oil, pecan oil
- Natural almond extract or other natural nut extract
- Pignoli or pine nuts
- Filbert or hazelnut
Food with tree nuts to check often
Which foods often contain tree nuts? The most common places are foods where nuts add crunch, richness, protein, or flavor. Obvious examples include trail mix, nut bars, mixed nuts, granola, and nut butters. Less obvious examples include pastries, chocolates, cereals, salads, sauces, and frozen desserts.
A tree nut allergy food list should include both packaged foods and foods prepared outside the package-label system, such as bakery case items, restaurant desserts, catering trays, and bulk-bin snacks. These foods may not have the same label format as a sealed grocery product, so you may need to ask more questions and decide whether the information is clear enough for your care plan.
For grocery routines, check each flavor and size rather than relying on the brand. A plain cookie, chocolate-dipped version, and holiday variety can have different ingredients. For broader planning habits, the guide to grocery shopping with food allergies can help you build a repeatable shopping process.
- Trail mix and snack mixes
- Granola, muesli, and cereal clusters
- Protein bars and energy bites
- Nut butters and spreadable fillings
- Cookies, cakes, brownies, and muffins
- Baklava, biscotti, macarons, and pastries
- Chocolate bars, truffles, and filled candies
- Ice cream, gelato, frozen yogurt, and toppings
- Pesto, romesco, mole, and some specialty sauces
- Salads with candied nuts or toasted nuts
- Stuffings, pilafs, grain bowls, and rice dishes
- Plant-based cheeses, cream sauces, and desserts made with cashews or almonds
Mixed-nut products and shared assortments
Mixed-nut products need extra attention because the ingredient list may include several kinds of tree nuts, peanuts, oils, seasonings, and sometimes sweet coatings. A front label such as “deluxe mixed nuts” or “party mix” does not tell you which nuts are inside or whether peanuts are included. Read the ingredient list for each nut and then check the allergen statement.
Variety packs and gift boxes can be especially confusing. One outer package may contain several inner packages, each with a different ingredient list. Chocolate assortments may place nut-filled pieces next to non-nut pieces, and bakery boxes may combine cookies with different toppings or fillings. If the inner item does not have its own clear label, the manufacturer or seller may be the only way to verify the details.
Bulk bins and scoop-your-own displays are also hard to interpret from a label alone. Scoops, bins, and nearby products can create cross-contact questions, and the ingredient card may not be updated in the same way as a sealed package label. When information is incomplete, treat the question as unresolved until you can verify it through the seller or manufacturer.
- Mixed nuts with peanuts and tree nuts
- Trail mix with several nut types
- Chocolate assortments with nut centers
- Holiday tins and gift baskets
- Bakery boxes with mixed cookies
- Bulk bins and scoop bins
- Shared candy bowls or party snack bowls
- Variety packs with different inner labels
Cross-contact and advisory wording
FDA allergen labeling rules focus on ingredients intentionally used in the food. They do not require a company to list every possible trace from shared equipment or shared facilities. That is where advisory wording may appear, such as “may contain tree nuts,” “made on shared equipment with almonds,” or “processed in a facility with walnuts.”
These advisory statements are voluntary. They are not standardized risk levels, so “may contain,” “made in a facility,” and “shared equipment” cannot be ranked reliably just by the phrase. One company may use different wording than another because of its equipment, cleaning process, supplier review, or legal language. The absence of advisory wording also does not prove that cross-contact is impossible.
Cross-contact questions come up often with tree nuts because many manufacturers handle several nuts on the same lines or in the same facility. A product that contains cashews may be made near almonds or pistachios. A chocolate product without nuts in the recipe may be produced on equipment that also handles hazelnut or almond items. Whether that fits your needs is a decision to make with your care plan and, when needed, the manufacturer.
- May contain tree nuts
- May contain almonds
- Made on shared equipment with tree nuts
- Processed in a facility with walnuts and cashews
- Manufactured in a facility that also processes peanuts and tree nuts
- Packed on equipment that handles mixed nuts
- No advisory statement shown
Label-reading routine for tree nuts
A steady routine helps when labels are long or the food looks familiar. Start with the exact package in your hand. Confirm the product name, flavor, and size, then read the full ingredient list from beginning to end. After that, check any Contains statement and any advisory wording. Do not stop at the front label, shelf tag, or an online photo if you have the actual package available.
For tree nuts, look for both the common nut names and food terms that may point to a nut ingredient. Then compare the ingredient list with the allergen statement. If the ingredient list says “almond flour,” the allergen information may say “Contains: Almond.” If the ingredient list says “praline pieces,” the rest of the label should clarify the nut source if a major-allergen tree nut is present.
Recheck familiar foods when packaging, flavor, or size changes. Seasonal candies, limited-edition baked goods, new “protein” versions, and imported products can differ from the standard item. Food Checker can be a quick second look when you scan an ingredient label, but it cannot replace the official package label, the manufacturer’s answer, or your healthcare professional’s guidance.
- Confirm product name, flavor, and size
- Read the full ingredient list
- Look for specific nut names
- Look for nut pastes, butters, oils, extracts, and fillings
- Check the Contains statement if one is present
- Review advisory wording for cross-contact
- Compare outer and inner labels on multipacks
- Recheck after package redesigns or recipe updates
When the label is unclear or the situation is uncertain
If a tree nut term, flavor, extract, oil, or advisory statement is unclear, set the product aside until you can verify it. Do not guess from the front of the package, a menu description, a shelf sign, or a memory of buying the item before. Recipes, suppliers, and production lines can change, and one flavor or size may not match another.
Contact the manufacturer with the exact product name, flavor, package size, lot code, and best-by date. Ask direct questions: which specific tree nut is in the ingredient, whether a flavor or extract is nut-derived, whether the oil is highly refined or less refined, and whether the product is made on shared equipment with the nut or nuts you are avoiding. If the answer is incomplete, the uncertainty remains.
For medical questions, diagnosis, symptoms, or how strictly to avoid a specific nut, use your healthcare professional or allergy care plan. A label guide can help you know what to look for, but it cannot decide whether a product is appropriate for you or replace individualized medical guidance.
- Set the product aside
- Keep the package and lot code
- Ask about the exact nut source
- Ask about flavors, extracts, oils, and pastes
- Ask whether shared equipment or facility wording applies
- Do not rely on another flavor’s label
- Follow your healthcare professional’s guidance and care plan
