For a summer-holiday nut snack, compare protein per 100g and the amount you plan to pack. Plain or unsalted peanuts are worth considering when salt matters, while seasoned peanuts may suit a preference for flavour; check the exact pack for salt, allergens and serving information before choosing.
If you want nuts for a travel day, walk or self-catering stay, compare the protein figure on the pack rather than relying on its front-of-pack wording. The peanut products listed by Sainsbury's, M&S and Tesco in this comparison range from 25.7g to 30g protein per 100g.
If salt affects your choice, compare the same per-100g figure across plain, unsalted and seasoned packs. The listed values differ between the specific products covered here; the flavour description alone does not give you the figure.
When others may eat from the pack, check its ingredients and allergen statements before packing it. Peanut and tree-nut risks are distinct, and a precautionary “may contain” statement can identify possible unintended allergen presence, as the Food Standards Agency explains.
Start with comparable nutrition figures, then check whether the portion, ingredients and warnings work for the people and activities involved.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Compare protein per 100g across equivalent products, then check the amount per stated serving. Sainsbury's lists 30g per 100g and 9g per 30g serving for KP Roasted Peanuts, Unsalted. | I want to know how much protein is in the portion I will take, not just how the pack is described. |
| Salt and seasoning | Read salt per 100g and the ingredient list. Sainsbury's lists less than 0.01g salt per 100g for its Fairtrade Peanuts; Tesco lists 0.99g per 100g for its Dry Roasted Peanuts. | If I prefer a savoury coating, I still want to see how its salt figure compares with a plain option. |
| Allergens and children | Check the exact pack's ingredients, allergen statements and any “may contain” wording. Read its choking warning before offering whole nuts to children. | Food I bring for a group needs to be suitable for the people who may eat it, especially anyone with an allergy or a small child. |
| Portions and storage | Compare energy per serving with the portion you intend to pack, and follow the pack's storage and after-opening instructions. M&S lists 621kcal per 100g for its Roasted Peanuts. | For a day out, I would rather set aside a portion than treat a larger pack as one snack. |
Nuts can provide protein while also contributing substantial energy. M&S lists 621kcal per 100g for its Roasted Peanuts, so the amount eaten matters as well as the per-100g protein figure.
Compare the figures for the portion you expect to eat. The British Nutrition Foundation suggests putting a portion of nuts in a bowl or choosing smaller packs rather than eating freely from a larger one.
“Dry roasted” does not mean unsalted. Tesco lists 0.99g salt per 100g for its Dry Roasted Peanuts, against less than 0.01g per 100g for Sainsbury's Fairtrade Peanuts.
If salt is a priority, compare the exact flavours and pack labels. The NHS advises checking food labels when cutting down on salt.
The Food Standards Agency distinguishes peanuts, which are legumes, from tree nuts. Individual packs may also carry warnings about other allergens or possible cross-contact.
Check the ingredients and precautionary statements on the pack you are taking, rather than relying on a different flavour or an earlier purchase.
Sainsbury's and Tesco product pages warn that small children can choke on nuts. A pack that works as an adult snack is not automatically suitable for everyone travelling.
Choose an age-appropriate alternative for small children instead of offering them whole nuts.
These examples describe specific listed peanut products, not every product sold under each name.

Choose by the flavour you want and the salt figure on the exact pack. Sainsbury's Fairtrade Peanuts list less than 0.01g salt per 100g, M&S Roasted Peanuts list 0.03g, and Tesco Dry Roasted Peanuts list 0.99g. The NHS advises checking labels when cutting down on salt.
No: the Food Standards Agency identifies peanuts as legumes and distinguishes them from tree nuts. That distinction does not establish whether a particular product is suitable for someone with an allergy. Check the exact pack's ingredients and precautionary statements and follow the person's allergy advice.
Do not offer whole nuts to small children: the Sainsbury's and Tesco peanut listings warn that they can cause choking. Check allergen information for everyone who may share the food and choose an age-appropriate alternative for small children.
Follow that pack's instructions rather than applying one product's directions to another. For example, M&S says to keep its Roasted Peanuts in a cool, dry place and eat them within one week of opening.
