Lunch packers seeking protein from the snack
If the snack needs to contribute protein to your office lunch, compare the amount in the pack you will eat, not just the product name or the per-100g figure.
Who is this lunch choice for?
People choosing crisps as a savoury side
A familiar potato crisp can provide crunch alongside a sandwich, salad or another lunch component. Check its pack size and protein figure if protein matters to your overall lunch choice.
Buyers with dietary requirements
Check the ingredients, allergen declaration and suitability statements for the exact flavour and pack. A potato base alone does not establish whether a seasoned crisp meets your requirements.
What should you check on the pack?
First decide whether the snack is a savoury side or is meant to supply protein. Then compare the serving you will pack with the per-100g nutrition information.
| Priority | What to check | Your needs |
|---|---|---|
| High-protein claim | Check protein and energy per 100g, rather than protein grams alone. The Great Britain criterion published on legislation.gov.uk requires at least 20% of a food’s energy to come from protein for a high-protein claim; protein contributes 17kJ per gram under the published conversion factors. | I want the snack itself to qualify as high protein, not merely to contain some protein. |
| Protein in the pack | Compare protein per individual pack as well as per 100g. Seabrook’s Beefy product page lists 2.2g per 31.8g bag; Joybuy’s Applied Nutrition High Protein Chips listing states 15g per 50g pack for a different, protein-enriched format. | If this is part of my packed lunch, the amount in the portion I take to work matters more than a figure for 100g I will not eat. |
| Ingredients and allergens | Read the exact flavour’s ingredients, allergen declaration and dietary-suitability statements. Pipers Lye Cross Cheddar & Onion lists cheese powder and milk powder; KETTLE Vegan Sheese & Red Onion is labelled vegan and gluten-free. | Milk ingredients or a specific dietary requirement could rule out one flavour even if another crisp suits me. |
| Pack and availability | Check the pack size, current listing and nutrition label before ordering. A product page can remain visible when an item cannot be purchased. | I need a snack I can pack for work, so I’ll confirm the portion and availability before making it part of my lunch plan. |
Common packed-lunch mistakes
-
Calling any crisp with protein “high protein”
A conventional crisp can list several grams of protein per 100g without meeting the Great Britain high-protein claim criterion. For example, KETTLE Vegan Sheese & Red Onion lists 8.0g protein and 2147kJ per 100g, which puts protein at about 6.3% of its energy using the published 17kJ-per-gram conversion factor.
Check both protein and energy per 100g against the 20% energy criterion published on legislation.gov.uk. Also check protein per pack to understand what the portion contributes to lunch.
-
Assuming a product page means the snack is in stock
A nutrition panel can help you assess a product format even when that particular item cannot be bought. Joybuy’s Applied Nutrition High Protein Chips listing states 15g protein per 50g pack but also says the item is no longer available.
Confirm current availability before choosing an item for upcoming packed lunches.
-
Assuming potato-based means suitable for every diet
Seasonings can change a crisp’s ingredients and allergen information. Pipers Lye Cross Cheddar & Onion, for example, lists milk-derived ingredients.
Read the declaration on the exact pack you buy, including any vegan or gluten-free statement you need.
How do the crisp brands differ?
These are references for comparing particular crisp ranges and flavours, not a list of brands whose products all qualify as high protein.
Walkers
Walkers has familiar potato-crisp formats, including Salt & Shake and baked snacks.
- Walkers lists 6.2g protein per 100g for Salt & Shake; its salt comes in a separate sachet.
- The Salt & Shake page says it is made in a factory that also handles milk, wheat, soya, gluten, barley, celery and mustard. Check the pack if those statements affect your choice.
Tyrrells
Tyrrells describes its potato crisps as hand-cooked in small batches from English potatoes, with the skins left on.
- The range includes plain and flavoured potato crisps for different flavour preferences.
- For a protein-focused lunch, compare the nutrition panel of the particular flavour and pack you intend to buy.
KETTLE Chips
KETTLE offers conventional potato crisps in flavours with distinct dietary-suitability statements.
- Its Vegan Sheese & Red Onion page lists 8.0g protein per 100g and labels that product vegan and gluten-free.
- That flavour’s declared energy means protein supplies about 6.3% of energy, below the Great Britain 20% high-protein claim criterion published on legislation.gov.uk.
Seabrook
Seabrook’s ridged potato-crisp range includes Beefy, a flavour the brand states is suitable for vegetarians and vegans.
- Seabrook’s Beefy nutrition panel gives both 6.9g protein per 100g and 2.2g per 31.8g bag.
- Use the per-bag figure when assessing its contribution to a packed lunch; the product should not be treated as a high-protein snack on the strength of its protein grams alone.
Pipers
Pipers offers flavoured potato crisps including Lye Cross Cheddar & Onion.
- Pipers lists 6.2g protein per 100g for that flavour and states that it is gluten-free and suitable for vegetarians.
- Its ingredients include cheese powder and milk powder, so this flavour does not suit a milk-free or vegan lunch.
Real Crisps
Real Crisps describes its hand-cooked range as vegetarian and gluten-free.
- The REAL Sweet Chilli product page lists 7.0g protein per 100g.
- The same page lists 1.7g salt per 100g. Compare the portion you plan to pack and the nutrition information of other flavours separately.
A Joybuy snack option for packed lunches
This lentil-cake option offers a different crisp-style format for an office lunch; it is not a conventional potato crisp. Check its pack nutrition information if a high-protein snack is your aim.

Kallo Protein Packed Lentil Cakes 100g
For a packed lunch where the snack itself is intended to contribute protein, consider these lentil cakes as an alternative format to sliced-potato crisps. Compare protein per serving and check the pack’s allergen information for your needs.
Questions about protein and crisps
What does “high protein” mean for a crisp in Great Britain?
Under the Great Britain high-protein claim criterion published on legislation.gov.uk, at least 20% of a food’s energy must come from protein for it to be described as high protein. Finding protein grams on a nutrition panel does not establish that the product meets the criterion.
Does KETTLE Vegan Sheese & Red Onion meet that high-protein criterion?
No. KETTLE lists 8.0g protein and 2147kJ per 100g for this flavour. Using the 17kJ per gram of protein conversion factor published on legislation.gov.uk, protein accounts for about 6.3% of its energy, below the Great Britain criterion of 20%.
Is a protein-focused crisp-style product the same as a potato crisp?
Not necessarily. Joybuy’s Applied Nutrition High Protein Chips listing describes a product made with dehydrated potato, pea protein, lentil flour and fava beans, rather than a conventional sliced-potato crisp. Its listed 15g protein per 50g pack is useful for comparing formats, but the page also says that item is no longer available; check current availability before making a purchase choice.
Do I need to check allergens on a potato-crisp pack?
Yes. Flavours can have different ingredients: Pipers lists cheese powder and milk powder in Lye Cross Cheddar & Onion, while KETTLE labels Vegan Sheese & Red Onion vegan and gluten-free. Read the ingredients, allergen declaration and suitability statements on the exact pack you buy.
