Runners watching snack portions
If you want nuts as a portable snack without eating an unmeasured handful, start with the amount you intend to have. Compare its calories with the pack’s per 100g figure.
Who is this for?
Runners choosing food before a 5k
If you need a snack shortly before setting off, consider whether a familiar carbohydrate-based food fits your timing better than nuts alone. The UK Sports Institute suggests a banana when there is little time before a parkrun.
Packaged-nut buyers checking salt or allergens
If seasoning or food allergies affect your choice, read the current ingredients, nutrition and allergen information for the exact pack rather than relying on the nut name.
What should you check?
A measured nut snack
Consider it when: You want a small snack around your usual meals and already know nuts suit you at that time.
Trade-off: The cited almond and pistachio servings contain little carbohydrate, so nuts alone are a poor substitute when a carbohydrate-based pre-run snack is what you need.
A carbohydrate-based pre-run snack
Consider it when: The run is soon and you need food before setting off; the UK Sports Institute gives a banana as a quick parkrun example.
Trade-off: Food choice and timing vary between runners, so use something familiar rather than trying a new snack immediately before a run.
| Priority | What to check | Your needs |
|---|---|---|
| Pre-run timing | Check when you will eat and the carbohydrate per serving. Tesco lists 2.1g carbohydrate per 30g of its almonds; Sainsbury’s lists 3.5g per serving of its pistachios. | If I need food shortly before a 5k, I want a familiar carbohydrate-based snack rather than relying on nuts alone. |
| Portion size | Compare calories per serving and per 100g, then measure the amount you will eat. Kent Community Health NHS Foundation Trust gives snack examples of 12 almonds at about 80 kcal and 24 pistachios at about 90 kcal. | I want a defined snack portion instead of eating directly from a large bag. Those NHS examples are approximate amounts, not calorie figures for every product. |
| Salt and seasoning | Compare salt on the same per 100g basis and read the ingredients. Sainsbury’s lists 1g salt per 100g for Fudco Roasted & Salted Jumbo Pistachios. | When I want an unseasoned snack, I’ll check the exact pack rather than assume all pistachios or almonds are prepared alike. |
| Allergens | Read the current ingredients and any precautionary allergen statement. GOV.UK says regulated allergens present as ingredients in UK prepacked food must be clearly indicated in the ingredients list. | If I’m buying for someone with a nut or peanut allergy, I need the information on this pack, not a previous purchase or the product name alone. |
Common buying mistakes
-
Calling a whole bag a low-calorie snack
Sainsbury’s pistachios list 604 kcal per 100g, while Tesco almonds list 635 kcal per 100g. The amount eaten changes the calorie comparison.
Count or weigh a portion before eating, and use the calorie figure on the pack for that amount.
-
Using nuts alone as a quick pre-run snack
Tesco almonds list 2.1g carbohydrate per 30g and Sainsbury’s pistachios list 3.5g per serving. These portions are not interchangeable with a carbohydrate-based snack.
If you need food shortly before a 5k, choose a familiar option that fits your timing; the UK Sports Institute suggests a banana when time is short.
-
Assuming the nut name tells you the salt content
Salt varies with the product. Sainsbury’s lists 1g salt per 100g for Fudco Roasted & Salted Jumbo Pistachios.
Compare the nutrition panel on an equal weight basis and check the ingredients for seasoning.
-
Relying on the front-of-pack name for allergy information
A name such as “pistachios” does not tell you everything about the ingredients or any product-specific cross-contact warning.
Check the current pack’s ingredients and allergen statement each time, particularly when buying for someone with a food allergy.
Brand and product-line references
These labelled examples help with comparisons; a brand name alone does not establish the nutrition or ingredients of another pack.
Sainsbury’s
Its Pistachio Nuts 100g provide a labelled serving and per 100g figures for a portion comparison.
- Sainsbury’s lists 181 kcal and 3.5g carbohydrate per serving.
- The same product lists 604 kcal per 100g, so the serving size matters.
Tesco
Tesco Almonds 200g give a 30g serving basis for comparison with other measured nut portions.
- Tesco lists 191 kcal and 2.1g carbohydrate per 30g.
- That serving contains little carbohydrate if a pre-run carbohydrate snack is the goal.
Fudco
Fudco Roasted & Salted Jumbo Pistachios illustrate why seasoning belongs in a pack-by-pack comparison.
- Sainsbury’s lists 579 kcal per 100g for this product, allowing a per 100g comparison.
- It also lists 1g salt per 100g; consider that separately from calories.
KP
KP Snacks maintains product information for its snack range, including ingredients and allergens.
- KP Snacks says it reviews and updates its product information sheets as products and recipes change.
- For an allergy or nutrition decision, use the details on the particular pack you are buying.
Planters
The figures for Planters Salted Peanuts come from the brand’s US product information, not a UK pack comparison.
- Planters’ US page lists 170 calories and 5g carbohydrate per stated serving.
- Do not apply that serving or labelling to a UK pack without checking the pack itself.

Questions about nuts and 5k runs
Are nuts suitable immediately before a 5k?
Nuts alone are not a like-for-like replacement for a carbohydrate-based snack when you need food shortly before running. The UK Sports Institute suggests a banana as a quick parkrun option; if you choose nuts, keep the portion small and use a food and timing you already know suit you.
How much is a measured nut snack?
Choose an amount you can count or weigh, then check its calories on the product label. Kent Community Health NHS Foundation Trust gives approximate snack examples of 12 almonds at 80 kcal and 24 pistachios at 90 kcal; those figures are not a prescription for pre-run fuelling or a value for every pack.
Are pistachios or almonds lower in calories?
The amount you eat matters more than comparing nut names without a shared serving size. Sainsbury’s lists 181 kcal per serving for its pistachios, while Tesco lists 191 kcal per 30g for its almonds; compare equal weights or the portions you will actually eat before drawing a conclusion.
What allergen details should I check on packaged nuts?
Check the current ingredients list and any precautionary allergen statement for the exact pack. GOV.UK says that when a regulated allergen is present as an ingredient in UK prepacked food, it must be clearly indicated in the ingredients list; a product name or an earlier pack is not a substitute for that check.
