Do not choose the checked potato crisps as a high-protein airport snack: their manufacturer-listed figures work out to about 3.4%–5.4% of energy from protein, while legislation.gov.uk sets the UK ‘high protein’ claim condition at at least 20%. The checked Tyrrells lentil crisps provide more protein per 100g than those potato-crisp examples but remain below that condition; if protein is the priority, check the claim and nutrition panel on a different snack, and choose crisps for their flavour or other stated attributes.
If protein is the reason for buying an airport snack, check the exact food rather than assuming crisps meet that aim. The potato crisps listed by Walkers, Seabrook, KETTLE Chips and Pipers in the examples below fall short of the UK ‘high protein’ claim condition.
If you want a dry, savoury snack for the journey, compare the flavour, pack size and nutrition information for the product you will carry. ‘Baked’ and ‘lentil’ describe different products; neither word establishes that a snack is high in protein.
If vegan, vegetarian or gluten-free suitability matters, check the exact flavour and pack. The checked KETTLE Chips and Seabrook products state those attributes, but that does not establish the suitability of other flavours.
Decide whether you are buying for protein or for a crisp snack, then compare the exact pack you intend to take through the airport.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Read protein and energy per 100g together. Legislation.gov.uk sets the UK ‘high protein’ claim condition at at least 20% of the food’s energy from protein; protein grams alone do not show whether it meets that condition. | If protein is my main reason for buying a snack, I want to check the claim and nutrition panel on the exact product, rather than rely on a crisp’s name or format. |
| Pack portion | Compare protein per pack or serving with the per-100g figure. Walkers lists 1.3g protein per 22g pack of its checked Oven Baked Sea Salt crisps. | A single pack is what I plan to eat on the journey, so its listed portion matters more to me than the per-100g figure alone. |
| Hand luggage | Keep the food accessible. GOV.UK says food items can obstruct X-ray images and a bag may need a manual security check. | I want a snack I can carry without having to search through my bag if security asks to inspect it. |
| Dietary suitability | Read the ingredients, allergen information and suitability statements for the exact flavour and pack. Do not apply one product’s statements to an entire range. | Vegan, vegetarian, gluten-free or allergen information may determine which flavour I choose; those statements do not answer my protein question. |
| Fat preference | Keep a reduced-fat comparison separate from the protein figures. Walkers states that its Oven Baked Sea Salt product has 50% less fat than regular potato crisps, but lists 1.3g protein per 22g pack. | If I am comparing fat content, that claim is relevant to me. If I am shopping for protein, I need to check protein separately. |
A food can list protein in grams without reaching the UK condition of at least 20% of its energy from protein, as set out by legislation.gov.uk.
Check both protein and energy for the exact food. For a rough comparison using kcal, multiply protein grams by 4 and divide by total kcal on the same quantity basis.
Walkers positions its checked Oven Baked Sea Salt crisps as lower in fat than regular potato crisps, while listing 1.3g protein per 22g pack.
Use the fat comparison for a fat-related decision, and read protein per pack separately.
Ingredients and suitability statements belong to specific products. A vegan or gluten-free statement on one flavour does not establish the ingredients or allergen information for another.
Check the pack of the exact flavour before buying, particularly if an allergen declaration affects your choice.
GOV.UK notes that food can obstruct security X-ray images and prompt a manual bag check.
Keep snack packs accessible in hand luggage so they can be shown if requested.
These manufacturer-listed figures describe the named products, not every flavour made by each brand.
Oven Baked Sea Salt offers a fat-related comparison for shoppers who still want potato crisps.
Sour Cream & Onion Lentil Crisps are a pulse-based crisp-style option, not potato crisps.
Sea Salt & Balsamic Vinegar is a potato-crisp example with stated dietary suitability.
Sea Salted is a potato-crisp example with stated ingredients and dietary suitability.
Anglesey Sea Salt is another named potato-crisp product to check by flavour rather than by brand alone.
These options include bars, lentil cakes and a seaweed snack for travellers considering something other than potato crisps. Check each pack’s nutrition and ingredients against your reason for buying; a protein-focused name alone does not establish that a product meets the UK ‘high protein’ claim condition.

A bar rather than a crisp for the journey. The name identifies four 40g bars; check protein per bar and the pack’s allergen information before choosing it for a protein-led snack.
No image available
A lentil-based cake to consider if you want a savoury alternative to potato crisps. The pack is named as 100g; check its protein and energy figures together before treating it as a high-protein choice.
No image available
A soft-core bar rather than a crunchy snack. The name specifies twelve 50g bars; check the nutrition information per bar and the pack warnings before taking one on a journey.
No image available
A flapjack option if a bar suits your journey better than crisps. The name identifies three 50g flapjacks; check the exact pack’s protein and energy figures rather than relying on ‘protein’ in its name.
No image available
A crispy seaweed snack rather than a potato crisp. The name specifies three 5g packs; compare nutrition per pack as well as per 100g, and check the ingredients for this flavour.
The checked potato crisps are not: figures listed by Walkers, KETTLE Chips, Seabrook and Pipers work out to about 3.4%–5.4% of energy from protein. Legislation.gov.uk sets the UK ‘high protein’ claim condition at at least 20%, so check another snack’s exact pack if protein is your priority.
No. Tyrrells lists 13g protein and 469 kcal per 100g for its checked Sour Cream & Onion Lentil Crisps, equivalent to about 11.1% of energy from protein. That is below the UK ‘high protein’ claim condition of at least 20% set out by legislation.gov.uk.
Food may prompt an additional bag check: GOV.UK says food items can obstruct security X-ray images and bags may need manual inspection. Keep the pack accessible and check the departure airport’s current instructions before travelling.
No. Those statements address different product attributes. The checked KETTLE Chips, Seabrook and Pipers products state dietary suitability but list 4.3g–5.9g protein per 100g; read the exact pack’s nutrition panel to assess protein.
Not on the basis of ‘baked’ alone. Walkers states that its checked Oven Baked Sea Salt crisps have 50% less fat than regular potato crisps, but lists 1.3g protein per 22g pack. Compare protein per pack separately from a fat claim.
