Students looking for an individual pack
An individual pack makes the serving size visible during a revision break. Compare its stated weight and nutrition rather than assuming that crisps affect concentration.
Who is choosing?
Flavour-first shoppers comparing salt and fat
Mild baked, lightly salted and vinegar-seasoned products offer different flavours and nutrition values. Compare the amount you expect to eat as well as the per-100g figures.
Shoppers checking dietary suitability
Vegan, vegetarian and gluten-free statements belong to specific products. Check the exact flavour’s ingredients and allergen declaration, including any may-contain statement.
What should you compare?
Start with the flavour and serving you would actually choose. Then read the nutrition and dietary information for that exact pack.
| Priority | What to check | Your needs |
|---|---|---|
| Serving size | Check the pack weight and stated servings. An individual pack gives a defined amount; a sharing bag can be portioned into a bowl. | If I take several snack breaks, I want to see how much is in each serving. In a September 2025 British Nutrition Foundation survey of over 2,500 UK schoolchildren aged 10–13, 79% reported having at least two snacks a day; the figure was not specific to revision or crisps. |
| Salt and fat | Compare figures per pack or serving, as well as per 100g. Walkers lists 0.17g salt per 25g Lightly Salted pack and 2.8g fat per 22g Oven Baked Sea Salt pack; those are different products and serving sizes. | I might prefer a mild flavour if one of those measures matters to me, but I still need to check both figures on the product I choose. |
| Flavour | Decide whether you want a mild, unseasoned or vinegar flavour, then check its nutrition. Seabrook lists 0.8g salt per 31.8g Sea Salt & Vinegar bag; Tyrrells lists 0.02g per 30g serving of its unseasoned Naked crisps. | A tangy flavour appeals to me, but its name alone tells me nothing about the salt in my serving. |
| Dietary label | Read the exact flavour’s vegan, vegetarian or gluten-free statement separately from its ingredients and allergen declaration. Check the current pack before relying on a may-contain statement. | If I avoid particular ingredients or allergens, another flavour from the same brand needs its own label check. |
| Where it is served | If a school will provide or sell the snack, ask it to check the applicable food standards and the exact product. Do not use a flavour name or one nutrition figure to decide an individual product’s policy classification. | A crisp I choose for a break at home is not automatically suitable for a school-provided snack. |
What is easy to overlook?

Judging salt by the flavour name
Seabrook Sea Salt & Vinegar lists 0.8g salt per 31.8g bag, while Walkers Lightly Salted lists 0.17g per 25g pack. The serving sizes differ, so the figures describe the amounts in those particular packs.
Compare salt for the amount you plan to eat, rather than treating vinegar seasoning as a sign of less salt.
-
Eating from a sharing bag without checking servings
Tyrrells describes its 150g Naked bag as five servings. The bag size is not the stated serving size.
Check the serving weight and put the amount you want into a bowl before returning to revision.
-
Applying one flavour’s dietary label to another
KETTLE Sea Salt & Balsamic Vinegar and Seabrook Sea Salt & Vinegar are labelled vegan and gluten-free, but suitability statements are product-specific. Other named crisps carry may-contain allergen statements.
For an allergy or necessary dietary exclusion, read the current exact pack’s ingredients and allergen declaration.
-
Assuming a home snack is approved for school provision
Food chosen at home and food provided by a school raise different questions. The Department of Health and Social Care describes the nutrient profiling model as a tool for identifying less healthy foods in relevant policy; a crisp’s status cannot be settled from its flavour name.
If the snack is for school provision or sale, ask the school or caterer to check the applicable rules and the exact product.

Questions about revision snacks
Will crisps help me concentrate while revising?
Do not choose crisps on the assumption that they improve concentration or exam performance. If you want an occasional savoury snack during a break, compare the serving size and nutrition for the pack you intend to eat.
How do I compare salt in different flavours?
Start with salt per pack or per stated serving, taking the different weights into account. Walkers lists 0.17g per 25g Lightly Salted pack and 0.19g per 22g Oven Baked Sea Salt pack; Tyrrells lists 0.02g per 30g serving of Naked, while Seabrook lists 0.8g per 31.8g Sea Salt & Vinegar bag.
Does vegan or gluten-free mean a crisp has less salt or fat?
No: dietary suitability and nutrition are separate label checks. KETTLE Sea Salt & Balsamic Vinegar and Seabrook Sea Salt & Vinegar are labelled vegan and gluten-free; KETTLE lists 1.6g salt per 100g, while Seabrook lists 0.8g per 31.8g bag.
What should I check if someone has a food allergy?
Read the current pack for the exact flavour, including its ingredients, highlighted allergens and may-contain statement. For example, McCoy's Salted may contain milk, soya, gluten and mustard, and Tyrrells Naked may contain milk.
Can a school provide crisps for a revision break?
A choice for a break at home does not establish whether a school can provide the same product. For school provision in England, ask the school or caterer to check the applicable Department for Education school-food standards and the exact product; do not assume the same answer applies across every UK nation.
