For fewer calories per 100g, consider plain chestnuts: Sainsbury's lists its chestnuts at 175 kcal per 100g, compared with 615–619 kcal per 100g for the KP peanut products listed by Tesco and Sainsbury's. If you prefer peanuts, a measured unsalted serving helps you track the amount eaten; a single-serve pack fixes the portion but does not make peanuts lower in calories by weight. Compare the calories in the amount you will actually eat, alongside salt, ingredients and any preparation needed.
The useful distinction is whether you want fewer calories by weight, a measured peanut serving or a way to keep salt in view.
Plain chestnuts are worth considering if reducing calories by weight matters more than choosing a conventional crunchy peanut snack. The Sainsbury's chestnuts used for this comparison require cooking and peeling, so check the preparation directions on the product you choose.
A measured serving may suit you if you prefer peanuts and can portion them before eating. Sainsbury's lists 186 kcal for a 30g serving of KP unsalted peanuts; a labelled single-serve pack offers another way to define the amount.
Compare the salt declaration as well as calories. The listed KP unsalted peanuts contain less than 0.01g salt per 30g serving, while Tesco lists 0.36g per 30g pack for KP salted peanut snack packs.
Choose the nut type first, then compare the portion you expect to eat. Pack format and salt can change which option is practical for you.
Consider when: Calories per 100g are your main comparison, and the product's texture and preparation suit you.
Trade-off: The Sainsbury's chestnuts used in this comparison need oven cooking and peeling; chestnuts are not a like-for-like replacement for a crunchy peanut snack.
Consider when: You want peanuts and can serve a planned amount from a larger pack.
Trade-off: KP unsalted peanuts list 619 kcal per 100g, so the amount eaten matters even when the nuts are unsalted.
Consider when: A defined pack is more practical than measuring peanuts from a larger bag.
Trade-off: The KP salted 30g pack listed by Tesco still provides 185 kcal and 0.36g salt.
| Priority | What to check | Your needs |
|---|---|---|
| Calories | Compare kcal per 100g for the nut type, then kcal in the amount you plan to eat. Sainsbury's lists chestnuts at 175 kcal per 100g and KP unsalted peanuts at 619 kcal per 100g; Tesco lists KP salted snack packs at 615 kcal per 100g. | I want to tell the difference between a lower-calorie option by weight and a small serving of a more calorie-dense nut. |
| Portion | Check the stated serving size, servings per pack and whether you will eat that amount. NHS Better Health notes that a manufacturer's portion may differ from your own. | When I snack away from home, a single pack may be easier to keep track of than an open, multi-serving bag. |
| Protein and fibre | Read both values for the same serving size. Sainsbury's lists 9g protein and 2.6g fibre per 30g serving of KP unsalted peanuts; compare those figures alongside calories, not instead of them. | I'd like to compare what a planned peanut serving contains without treating its protein or fibre as a reason to ignore the portion. |
| Salt | Compare salt per portion on the exact pack. The listed KP unsalted peanuts have less than 0.01g per 30g serving; Tesco lists 0.36g per 30g KP salted snack pack. NHS Healthier Families suggests unsalted nuts as a swap when reducing salt. | Salt matters to me as well as portion size, so a salted single-serve pack may not meet both preferences. |
| Ingredients and preparation | Read the current ingredient and allergen statements. Check whether chestnuts need cooking or peeling, and follow the storage and preparation directions for the particular product. | I need an option I can prepare and store as directed, with ingredients that are suitable for my household. |
The listed products differ substantially by weight: Sainsbury's chestnuts provide 175 kcal per 100g, while the KP peanut products listed by Sainsbury's and Tesco provide 615–619 kcal per 100g.
Use the per-100g figures to compare products, then check the calories in the portion you intend to eat.
The KP unsalted 250g pack is labelled as several servings, with 186 kcal in each stated 30g serving. Eating more than that changes the calories you need to account for.
Portion peanuts before snacking, or choose a genuinely single-serve pack if that format works better for you.
A 30g pack defines a portion but does not change the peanuts' calories per 100g. Tesco lists 0.36g salt in each KP salted 30g snack pack.
If you are also reducing salt, compare that pack with an unsalted option rather than judging it on portion size alone.
Ingredients and handling matter as well as nutrition. The listed KP unsalted peanuts contain peanuts and carry a statement about possible other allergens; the Sainsbury's chestnuts used in the comparison need cooking and peeling.
Check the current pack's allergen statement and follow its preparation and storage instructions before use.
These examples show what to look for in specific product lines; a brand name alone does not establish a product's calories, portion size or suitability.
Its Chestnuts 400g listing offers a plain chestnut example for comparing calories per 100g with peanuts.
The listed unsalted peanuts and salted snack packs illustrate the choice between measuring a serving and buying a fixed-size pack.
Its nuts category includes several formats, including peanuts, dry-roasted nuts and nut mixes.
Its Whole Chestnuts listing describes fire-roasted chestnuts for dishes including stuffings and risottos.
These options cover chestnuts for snacks or cooking, unsalted peanuts to portion yourself and peanut snack packs with a defined serving. Compare the exact product label before choosing.

The sachet format may help if you prefer to open a defined amount of chestnuts at a time. The product name identifies these as peeled, ready-to-eat chestnuts; check the nutrition declaration on the pack for the calories in the amount you eat.

This pouch suits shoppers who want to measure out chestnuts for a snack or meal. Joybuy lists whole chestnuts as the ingredient, 170 kcal and 0.02g salt per 100g; refrigerate unused contents in a sealed container and use them within 3 days of opening, as the listing directs.

Consider these chestnuts for cooking rather than a snack straight from the bag. They require frozen storage and boiling before eating; portion the 454g bag according to the amount you plan to use, and follow the pack directions.

This is an option for a planned peanut serving when you also prefer unsalted nuts. Sainsbury's lists 186 kcal, 9g protein and less than 0.01g salt per 30g serving of the same product, and 619 kcal per 100g; measure your portion from the 250g pack.

Five 30g packs offer a defined amount when serving peanuts from a larger bag would be less convenient. Portion size does not establish low calories per 100g; check this dry-roasted variant's calorie and salt declarations rather than using figures from a different KP snack pack.
The specific plain chestnuts and peanut products compared here differ by weight: Sainsbury's lists its chestnuts at 175 kcal per 100g and KP unsalted peanuts at 619 kcal per 100g; Tesco lists KP salted snack packs at 615 kcal per 100g. Check the label of the chestnut or peanut product you intend to buy, as the comparison does not describe every variety or preparation.
No: a smaller pack defines the amount, not the product's calories by weight. Tesco lists 185 kcal in one 30g KP salted peanut snack pack and 615 kcal per 100g for the same product. The pack may be useful if a fixed serving is easier for you to track.
Yes, if salt matters to your choice, compare the declarations on the exact products. Sainsbury's lists less than 0.01g salt per 30g serving for KP unsalted peanuts, while Tesco lists 0.36g per 30g KP salted snack pack. NHS Healthier Families suggests swapping salted nuts for unsalted nuts when reducing salt.
Check calories per 100g and work from the amount you actually eat, rather than assuming the label's serving size matches your portion. NHS Better Health explains that a manufacturer's portion may differ from yours. Measuring from a larger bag or using a single-serve pack can make the amount easier to keep track of.
Read the current ingredient and allergen statements for the exact pack before buying or eating it. The Sainsbury's listing for KP unsalted peanuts states that the product contains peanuts and may contain other nuts, milk, soya and gluten; do not assume another nut product has the same declaration.
