For a snack you can put straight in your bag, choose a portioned pack and compare its protein per pack: M&S declares 10g in its 30g nut-and-seed mix, while the larger KP Original Salted Peanuts pack declares 15g in 50g. For a student cupboard, a larger peanut pack makes sense if you can portion and store it; compare protein and salt per 100g, and check the exact pack’s allergens before buying.
The useful pack size depends on whether the nuts are going into a bag or a kitchen cupboard.
A single pack gives you a defined amount for travel or study. M&S declares 10g protein in its 30g Protein Packed Nut and Seed Mix; the KP Original Salted Peanuts listing declares 15g in a 50g pack. Check the pack size alongside the protein figure.
A larger peanut pack can be portioned at home rather than carried whole. Before choosing one, consider where you will keep it after opening and whether you will use it within the label’s storage guidance.
Protein figures alone cannot settle this choice. Marks & Spencer lists 0.03g salt per 100g for its Roasted Peanuts, while the KP Original Salted Peanuts listing gives 1.2g per 100g. Allergen declarations also differ between mixes, plain peanuts and seasoned products, so use the exact pack label.
Start with the amount you expect to eat, then compare labels on the same basis. Pack size, salt and ingredients may change which option works for moving in.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Compare protein per 100g, then protein in the pack or portion you would eat. M&S declares 34.4g per 100g and 10g per 30g pack for its nut-and-seed mix; the KP Original Salted Peanuts listing declares 30g per 100g and 15g per 50g pack. | If I am taking one pack to a lecture, its per-pack figure matters as much as its per-100g figure. |
| Pack and storage | Check whether the product is a single snack pack or a larger pack you must portion. Follow its post-opening instructions: Sainsbury’s says to store its 550g Salted Peanuts airtight and consume them within seven days of opening. | A cupboard pack suits me if I have a container for it and expect to use it within the stated storage period. |
| Salt and energy | Read salt per 100g and for the amount you plan to eat. Marks & Spencer declares 0.03g salt per 100g for its Roasted Peanuts; the KP Original Salted Peanuts listing declares 0.60g salt and 308kcal in its 50g pack. | I want to compare the snack I would actually eat, not choose on protein alone. |
| Ingredients and allergens | Check the exact product’s ingredients, allergen declaration and precautionary statements. A nut-and-seed mix, plain peanuts and seasoned peanuts need not have the same ingredients. | In a shared kitchen, I need to know which pack is suitable for the people who might eat it; a familiar brand name is not enough. |
The KP Original Salted Peanuts listing declares 15g protein in its 50g pack, alongside 0.60g salt and 308kcal. Those per-pack figures matter if you intend to eat the whole pack.
Compare protein, salt and energy both per 100g and for the portion you expect to eat.
Marks & Spencer declares 0.03g salt per 100g for its Roasted Peanuts; the KP Original Salted Peanuts listing declares 1.2g per 100g. Choosing between roasted and salted products can therefore change the salt figure substantially.
If salt affects your choice, check the salt line on the specific pack rather than relying on the word “peanuts”.
The Food Standards Agency identifies peanuts as legumes, distinct from tree nuts. Individual snacks can also have additional ingredients and precautionary allergen statements.
For an allergy, read the current physical pack and seek advice from a relevant healthcare professional rather than deciding suitability from a product category.
A larger pack still needs somewhere suitable to go after opening. Sainsbury’s advises airtight storage and consumption within seven days for its 550g Salted Peanuts.
Check the chosen pack’s instructions and consider how often you will use it before opening it.
A pack that loses quality before you finish it can lead to food waste.
These examples refer to particular product lines, not to every nut snack sold under each name.
Marks & Spencer lists both a 30g Protein Packed Nut and Seed Mix and a separate 300g Roasted Peanuts pack.
The KP Original Salted Peanuts 50g listing is a small-pack example for students who want a defined snack to carry.
ASDA Salted Peanuts 500g is an example of a larger cupboard pack for self-portioning.
Sainsbury’s Salted Peanuts 550g is another larger-pack option rather than a ready-portioned snack.
Tesco Dry Roasted Peanuts 550g provides a seasoned, larger-pack alternative to plain salted peanuts.
These options include peanut packs for a student cupboard, a multipack with smaller bags and a seed-and-berry mix for adding to food. The seed mix is not a nut snack; compare each product’s pack and label with the way you plan to use it.

A 250g peanut pack to portion from a cupboard rather than carry as one snack. Check the current nutrition and allergen label, and follow its instructions after opening.

Five 30g bags provide separate portions for carrying. Check the nutrition and allergen information for this exact multipack rather than applying figures from a different KP pack size.
No image available
This is a seed-and-berry mix, not a pack of nuts. Consider it if you want an ingredient to add to food; check its label for nutrition, allergens and storage instructions.

A larger seasoned peanut pack to portion yourself. Joybuy’s listing declares 27.7g protein and 1.3g salt per 100g, and identifies peanuts and wheat as allergens; check the current pack before sharing it.
No image available
A larger salted-peanut pack for self-portioning. Check protein and salt on this 415g product’s own label: figures for the separately listed 50g KP pack should not be assumed to apply to it.
No. The protein grams for the amount you eat are a separate figure to check. M&S declares 10g in its 30g Protein Packed Nut and Seed Mix, while the KP Original Salted Peanuts listing declares 15g in its 50g pack; compare salt, energy, ingredients and allergens as well.
Choose an individual pack if you want a defined amount to carry; choose a larger pack if you can portion and store it as directed. For example, Sainsbury’s tells buyers of its 550g Salted Peanuts to store them airtight and consume them within seven days after opening.
No. The Food Standards Agency identifies peanuts as legumes, distinct from tree nuts. That distinction does not establish whether a particular snack is suitable for someone with an allergy: check the exact pack’s ingredients, allergen declaration and precautionary statements.
Compare salt per 100g first, then consider how much you would eat. Marks & Spencer declares 0.03g per 100g for its Roasted Peanuts, while the KP Original Salted Peanuts listing declares 1.2g per 100g. The products also differ in pack size and ingredients.
No. Read the current physical pack before eating or sharing it, including ingredients and precautionary statements. Peanut, nut-and-seed and seasoned products can have different declared allergens, even when their protein figures look similar.
