Unsalted nuts are not a low-fat substitute: Tesco, Sainsbury’s and M&S product listings give 47g to 55g fat per 100g for the examples compared here, while the low-fat claim criterion for solid foods shown on legislation.gov.uk is no more than 3g per 100g. If you need to avoid peanuts or tree nuts, choose a non-nut snack and check its current label for the specific allergen; if you follow a prescribed minimal-fat diet, follow your individual dietary plan rather than treating unsalted nuts as a suitable snack.
The right choice depends on whether your concern is total fat, salt or a named allergen: those are separate checks.
An unsalted label can help you identify a product without added salt, but it says nothing about total fat. Compare the current pack’s fat and saturated fat figures on the same per-100g basis, then look at the amount in the portion you intend to eat.
Oxford University Hospitals NHS Foundation Trust lists nuts and seeds among foods to avoid in its guidance for a diet of 20g fat or less per day. Use the dietary plan given to you for decisions about individual foods.
Name the allergen you need to avoid before choosing a snack. GOV.UK allergen guidance identifies peanuts and tree nuts separately; check both the ingredients and any precautionary wording on the current pack.
Start with the requirement that rules a product in or out for you. Then compare nutrition figures using the same basis, rather than relying on words such as “unsalted” or “dry roasted”.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare fat per 100g, then fat in the stated serving. Legislation.gov.uk gives no more than 3g per 100g as the low-fat claim criterion for solid foods; Tesco Unsalted Mixed Nuts list 55g per 100g and 13.8g per 25g serving. | I need to know how much fat the portion I might eat would contribute, not just whether the pack says “unsalted”. |
| Named allergens | Check the current ingredients for peanuts and each relevant tree nut. Read any “may contain” statement for the allergen you must avoid; the Food Standards Agency explains that this wording can signal unintended allergen presence. | “Free from” needs to refer to the particular allergen I am avoiding. A gluten-free or vegan description does not answer whether a snack contains peanuts or tree nuts. |
| Salt and seasoning | Compare declared salt on the same per-100g or serving basis. Read the ingredients of flavoured products separately; “unsalted” and “dry roasted” do not establish their fat content or allergen suitability. | If added salt is my concern, I can compare unsalted products without assuming they are low fat. If I want a flavoured snack, I still need to check its full label. |
| Saturated fat | Use the saturated fat figure on the nutrition label to compare products on a like-for-like per-100g basis. Keep it separate from the total-fat figure; the NHS advises comparing food labels when shopping to reduce saturated fat. | I may be comparing saturated fat rather than following a limit on total fat, so I need to use the figure that matches my aim. |
Sainsbury’s lists KP Unsalted Roasted Peanuts at 51g fat per 100g and 15g per 30g serving. Removing added salt does not remove the fat in the nuts.
Compare total fat per 100g and per portion. If you have been given a minimal-fat dietary plan, use that plan when deciding whether to include nuts.
GOV.UK allergen guidance treats peanuts and tree nuts as distinct allergens. A product described as free from a different ingredient may still contain the one you need to avoid.
Identify the exact allergen, then check the current ingredients and precautionary allergen wording for it each time you buy.
M&S Dry Roasted Peanuts list 47g fat per 100g. That is below the other nut examples compared here, but above the 3g-per-100g low-fat claim criterion for solid foods shown on legislation.gov.uk. M&S also states allergy and coeliac exclusions for this product.
Choose a flavour only after checking the product’s fat figure, ingredients and suitability for the allergens relevant to you.
These product listings illustrate why the exact pack matters; a figure or allergen statement for one product should not be applied to another product from the same brand or retailer.
KP Unsalted Roasted Peanuts are an example of an unsalted nut snack.
Tesco Unsalted Mixed Nuts provide a mixed-nut example for comparing ingredients and portion figures.
Its dry-roasted peanuts and roasted-and-salted mixed nuts illustrate differences between products within one retailer’s range.
Its KP Unsalted Roasted Peanuts listing supplies a retailer example for checking a named product’s nutrition.
This pitted-prune product is a non-nut option to consider if you are looking beyond nut snacks. Check the current pack’s fat, sugars, ingredients and allergen information against your own requirements; being a dried fruit does not itself establish a free-from claim.

Individually wrapped pitted prunes offer a dried-fruit alternative to a nut snack. Compare the current pack’s total fat and sugars per 100g, and check its ingredients and allergen information before deciding whether it meets your needs.
The unsalted products compared here are not: Sainsbury’s lists KP Unsalted Roasted Peanuts at 51g fat per 100g, and Tesco lists its Unsalted Mixed Nuts at 55g per 100g. “Unsalted” concerns salt, while legislation.gov.uk gives no more than 3g fat per 100g as the low-fat claim criterion for solid foods.
Use the individual dietary plan provided to you rather than assuming nuts fit because they are unsalted. Oxford University Hospitals NHS Foundation Trust lists nuts and seeds among foods to avoid in its guidance for a diet of 20g fat or less per day.
No. Those descriptions do not establish the absence of peanuts or tree nuts. GOV.UK allergen guidance identifies peanuts and tree nuts separately, so check the current ingredients for the particular allergen you need to avoid.
It is precautionary allergen wording indicating that an allergen could be unintentionally present, as explained by the Food Standards Agency. Check whether the statement names the allergen you need to avoid rather than treating it as a free-from assurance.
Yes. Check the current pack’s ingredients, allergen wording and nutrition figures before choosing it, particularly if a named allergen or a total-fat limit determines whether it suits your needs.
