People carrying lunch to work or elsewhere
If you want a snack that fits in a bag, a 30g pack gives you a defined portion. With a larger bag, decide how much to take before leaving.
Who is this for?
Shoppers comparing salt in peanut snacks
Check salt for the portion you plan to eat. KP Nuts lists 0.51g salt per 30g dry-roasted snack pack, while Sainsbury’s lists less than 0.01g per 30g serving of KP unsalted peanuts.
People choosing between nuts and bars
Compare protein using the stated serving sizes, then check sugars, salt and allergens. A bar and a small nut pack need not have the same weight or ingredients.
What should you compare?
Start with the amount you would eat at lunch, then read the nutrition and ingredient information for that portion.
| Priority | What to check | Your needs |
|---|---|---|
| Protein and portion | Compare protein per pack or chosen serving, alongside pack weight. Marks & Spencer lists 10g per 30g mix pack; KP Nuts lists 9g per 30g dry-roasted pack, and Sainsbury’s lists 9g per 30g serving of KP unsalted peanuts. | I want to know how much protein is in the amount I will carry and eat, rather than comparing per-100g figures alone. |
| Salt | Read the salt line for the same serving size. KP Nuts lists 0.51g per 30g dry-roasted pack; Sainsbury’s lists less than 0.01g per 30g of KP unsalted peanuts. | When salt matters to my choice, I want to compare the actual servings rather than rely on words such as “roasted”. |
| Ingredients and allergens | Read the current pack’s ingredients, highlighted allergens and any “may contain” statement. UK food-labelling guidance from GOV.UK covers ingredient and allergen information; the Food Standards Agency explains that precautionary wording signals possible unintended allergen presence. | I need to check the particular mix or peanut product against the allergens I avoid, including possible cross-contact warnings. |
| Pack format | Check whether the stated serving is the whole pack or part of a larger bag. The KP unsalted peanuts listed by Sainsbury’s come in a 250g bag, while the compared M&S mix and KP dry-roasted snack are 30g packs. | A single pack suits me when I want a ready-portioned snack; with a larger bag, I would take a separate portion for lunch. |
Common buying mistakes
-
Comparing protein per 100g without checking the pack
A 30g nut pack and a 46g bar contain different amounts of food, so per-100g figures alone do not show what you would get from either snack.
Compare protein per pack or intended portion first. Use per-100g figures when you want to compare the products on an equal-weight basis.
-
Treating dry-roasted and unsalted peanuts as interchangeable
For the KP products listed by KP Nuts and Sainsbury’s, both stated 30g servings provide 9g protein, but the dry-roasted pack lists 0.51g salt and the unsalted peanuts list less than 0.01g.
If salt affects your choice, check the per-serving figure on the particular pack.
-
Assuming a protein bar has the same nutrition as plain nuts
Serving sizes and ingredients differ. Tesco lists 10.9g protein, 9g sugars and 0.45g salt per 46g Pip & Nut Protein Peanut Butter Bar.
Compare the bar’s protein, sugars, salt and allergens with the nut portion you would otherwise eat.
-
Taking a large bag without planning a portion
The KP unsalted peanut bag listed by Sainsbury’s weighs 250g, while its stated nutrition figures are for 30g.
Put your intended serving in a small container before packing lunch, or choose a single-serve format if that is more convenient.

Questions about lunch-sized nut snacks
What should I compare first when packing a nut snack for lunch?
Start with protein in the pack or portion you intend to eat. Then check its weight, salt, sugars, ingredients and allergens; a protein figure on its own does not describe the whole snack.
Do KP unsalted peanuts and dry-roasted peanuts provide different amounts of protein?
The compared KP products both list 9g protein per 30g. KP Nuts lists 0.51g salt for its dry-roasted snack pack, while Sainsbury’s lists less than 0.01g for a 30g serving of KP unsalted peanuts; the latter comes in a larger bag that you would need to portion.
Is a website listing enough to check allergens?
Check the current physical pack before eating, including its ingredients, highlighted allergens and any “may contain” wording. GOV.UK guidance covers allergen information in ingredient lists, and the Food Standards Agency explains that precautionary wording concerns possible unintended allergen presence.
Are peanuts the same as tree nuts?
No. The Food Standards Agency identifies peanuts as legumes. That distinction does not establish whether a particular mixed snack is suitable for someone avoiding an allergen, so check the product’s full allergen statement.
