For a quick desk lunch, a plain or unsalted peanut bag makes sense if you can portion it yourself and want to keep salt in view alongside protein. A sealed 30g or 50g pack gives you a defined portion without measuring, but compare its protein, salt and energy per pack. Check the current allergen label whichever format you choose.
If lunch needs a quick savoury addition, look at the amount in the portion you will eat. Tesco Groceries lists 9g protein for a 30g KP Original Salted pack and 15g for a 50g KP Dry Roasted pack; a larger bag needs portioning.
Plain and unsalted options are worth comparing with seasoned packs. Tesco Groceries lists less than 0.01g salt per 25g serving of Tesco Jumbo Peanuts, while Asda lists less than 0.01g per 30g serving of KP Unsalted.
A sealed pack sets the portion in advance; a larger bag lets you serve yourself. The British Heart Foundation describes a small handful as about 30g and notes that 30g of nuts can contain 180–225kcal, depending on the type.
Start with the portion you are likely to eat, then compare its label with the storage and allergen checks that matter at your desk.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Read grams per pack or intended serving, then use per-100g figures for a like-for-like comparison. Tesco Groceries lists 9g in a 30g KP Original Salted pack and 15g in a 50g KP Dry Roasted pack. | I want to know what my actual desk portion provides, not just compare figures for 100g that I may not eat. |
| Salt and energy | Compare salt and energy for the same portion size. Tesco Groceries lists 0.39g salt per 30g KP Original Salted pack and 0.80g per 50g KP Dry Roasted pack. The British Heart Foundation notes that 30g of nuts can contain 180–225kcal, depending on type. | If I am watching salt or planning a defined snack, the serving figures matter as much as the protein figure. |
| Allergen label | Read the current ingredients and precautionary allergen statement on the exact pack. The Food Standards Agency distinguishes peanuts, which are legumes, from tree nuts. | I need to check the product I am buying rather than assume that every food described as “nuts” has the same allergen information. |
| Pack and storage | Decide whether you want a sealed serving or will portion a larger bag. Follow the opened-pack instructions; Sainsbury's lists cool, dry storage and consumption within seven days of opening for KP Unsalted 250g. | A single pack is simpler to carry, while a larger bag works for me if I can portion and store it as directed. |
Pack size changes the amount you get: Tesco Groceries lists 9g protein in a 30g KP Original Salted pack and 15g in a 50g KP Dry Roasted pack.
Compare the grams of protein in the pack or portion you intend to eat; use per-100g values to compare products on the same basis.
Asda lists less than 0.01g salt per 30g serving of KP Unsalted, while Tesco Groceries lists 0.39g per 30g KP Original Salted pack and 0.80g per 50g KP Dry Roasted pack.
If salt matters to your choice, compare the current nutrition panels at the serving sizes you expect to eat.
A large bag does not define one desk serving. The British Heart Foundation describes a small handful as about 30g and notes that 30g of nuts can contain 180–225kcal, depending on type.
Portion a larger bag before lunch, or choose a sealed pack if you would rather not measure at your desk.
The Food Standards Agency distinguishes peanuts from tree nuts. Ingredients and precautionary allergen statements also need checking on the particular product.
For an allergy-related choice, read the current physical pack rather than relying on a category name or a previous purchase.
The checked KP products include unsalted peanuts in a larger bag and salted or dry-roasted single packs.
Tesco Jumbo Peanuts are a plain, larger-bag option for shoppers who will portion their own serving.
M&S Roasted and Salted Peanuts provide another labelled peanut option to compare by portion.
The relevant Sainsbury's listing is for KP Unsalted 250g, not a Sainsbury's own-brand peanut product.
The relevant Asda listing is also for KP Unsalted 250g, rather than an Asda own-label range.
These options include larger peanut bags, portioned peanut packs and a peanut-and-chocolate bar; the bar is a different format from a bag of nuts.

Five 30g portions suit a desk routine where you want a defined pack rather than serving from a larger bag. Check protein, salt, energy and allergens on this multipack's current label; figures for a different KP pack size should not be assumed to apply.

This 390g honey-roast peanut bag offers a different flavour from plain or salted peanuts and needs portioning for a desk snack. Read its own nutrition, ingredient and storage information rather than assuming it matches an unsalted variety.
No. The Food Standards Agency distinguishes peanuts, which are legumes, from tree nuts. For an allergy-related purchase, read the exact product's current ingredients and precautionary allergen statement.
Choose a sealed pack if a defined, portable portion matters most; choose a larger bag if you can portion and store it yourself. The British Heart Foundation describes a small handful of nuts as about 30g and notes that its energy content can vary by nut type.
Follow the instructions on that pack. Sainsbury's listing for KP Unsalted 250g says to keep it in a cool, dry place and consume it within seven days of opening.
Compare the portion sizes before deciding: Tesco Groceries lists 9g protein in a 30g KP Original Salted pack, while Asda lists 9g per 30g serving of KP Unsalted 250g. Their salt figures differ, so check both protein and salt on the exact pack.
