Who is this decision for?

The useful choice depends on whether you need the snack itself to meet a high-protein threshold, or mainly want a savoury crunch at elevenses.

Shoppers with a firm high-protein requirement

A protein figure on a potato-crisp packet is not enough to establish a high-protein claim. Compare protein with the food’s energy value, or check an explicit claim on the exact product you intend to buy.

Crisp eaters open to a lentil alternative

Changing the base ingredient offers another way to compare savoury snacks. Tyrrells lists 4.2g protein per 30g serving for its Sour Cream & Onion Lentil Crisps, but their listed nutrition puts them below the 20%-of-energy high-protein threshold.

Regular savoury-snack buyers checking ingredients

If salt or a particular ingredient matters to your choice, compare the portion you will eat and read the exact flavour’s label. The Food Standards Agency says allergens in prepacked food must be emphasised in the ingredients list.

What should you check before choosing?

Decide first whether potato crisps are essential to your elevenses. Then compare the portion and nutrition information for the type of snack you would actually eat.

Stay with potato crisps

Choose when: potato-crisp flavour and crunch matter more than getting a high-protein snack.

Trade-off: the checked potato-crisp labels list protein, but the protein figure alone does not establish a high-protein claim.

Try lentil crisps

Choose when: a crisp-style snack matters, but a potato base does not.

Trade-off: Tyrrells’ checked lentil flavour has more protein per 100g than the potato-crisp examples here, yet is not high protein by the 20%-of-energy measure.

Choose another snack type

Choose when: meeting a high-protein requirement takes priority over having crisps.

Trade-off: you will need to check the individual product’s nutrition and ingredients rather than assume its name establishes its protein level.

Priority What to check Your needs
High-protein claim Check protein and energy for the same quantity. Regulation (EC) No 1924/2006 states a threshold of at least 20% of energy from protein for a high-protein claim. If high protein is essential to my elevenses, I cannot judge a crisp by its protein grams alone.
Portion size Compare protein per stated bag or serving, then use per-100g figures for a consistent product comparison. Walkers lists 1.6g per 25g for Ready Salted; Tyrrells lists 4.2g per 30g for Sour Cream & Onion Lentil Crisps. I want to know what the portion I plan to eat provides, rather than compare two differently sized servings as though they were equal.
Salt Read salt per bag or serving on the exact flavour; use per-100g figures when pack sizes differ. Walkers lists 0.34g per 25g for Ready Salted. Crisps are a regular elevenses choice for me, so the salt in each pack matters alongside its protein.
Ingredients Read the ingredients and any precautionary allergen statement on the exact pack. Seabrook lists whey powder (milk) in its Cream Cheese & Chive crisps; the Food Standards Agency explains how allergens are identified on prepacked food. I need to check a particular ingredient or dietary label, not assume every flavour in a brand’s range is alike.

What can lead to the wrong choice?

  • Treating any protein figure as a high-protein claim

    Protein grams show that a food contains protein, not what proportion of its energy comes from protein. KETTLE Chips lists 8.0g protein and 514 kcal per 100g for Vegan Sheese & Red Onion potato crisps; that works out at about 6.2% of energy from protein.

    If high protein is a firm requirement, check the claim and nutrition information for the specific snack rather than relying on the presence of protein on the panel.

  • Comparing only per-100g figures

    The amount in the packet you eat can differ from the per-100g figure. Walkers Ready Salted lists 1.6g protein per 25g, while Tyrrells Sour Cream & Onion Lentil Crisps lists 4.2g per 30g serving.

    Look at the stated serving and its size first; use per-100g values to compare products on the same basis.

  • Assuming lentil crisps are automatically high protein

    Tyrrells lists 14g protein and 462 kcal per 100g for its Sour Cream & Onion Lentil Crisps. Protein supplies about 12.1% of that energy: above the separate 12% threshold for a source-of-protein claim in Regulation (EC) No 1924/2006, but below its 20% high-protein threshold.

    Choose them if a non-potato crisp and their stated protein per serving suit your needs; do not treat the ingredient switch as proof of a high-protein claim.

  • Overlooking salt and flavour-specific ingredients

    Protein is only one part of the label comparison. Seabrook’s Cream Cheese & Chive ingredients include whey powder (milk), while salt figures vary between the checked products.

    Check salt for the portion you will eat and read the ingredients and allergen information on that flavour’s pack.

Which brand ranges are relevant?

These brand examples help distinguish potato crisps from a lentil alternative; the figures apply to the named flavours, not every product in each range.

Walkers

A potato-crisp range that includes Ready Salted and an Oven Baked Sea Salt variant.

  • Walkers lists 1.6g protein per 25g and 6.4g per 100g for Ready Salted.
  • Its Oven Baked Sea Salt label lists 1.3g protein per 22g; a different preparation does not establish a high-protein claim.

Tyrrells

Offers a lentil-crisp range alongside potato crisps, for shoppers willing to change the base ingredient.

  • Tyrrells lists 4.2g protein per 30g for Sour Cream & Onion Lentil Crisps.
  • This is a lentil crisp, not a potato crisp; its listed protein and energy put it below the 20%-of-energy high-protein threshold.

KETTLE Chips

A potato-crisp range that includes the Vegan Sheese & Red Onion flavour.

  • KETTLE Chips lists 8.0g protein per 100g for that flavour and describes it as vegan and gluten-free.
  • At the stated 514 kcal per 100g, about 6.2% of its energy comes from protein.

Seabrook

A potato-crisp range with per-bag nutrition stated for the checked Cream Cheese & Chive flavour.

  • Seabrook lists 1.5g protein per 25g bag for that flavour.
  • Its ingredients include whey powder (milk), so check the exact flavour when ingredients matter.

Pipers

A potato-crisp range that includes Karnataka Black Pepper & Sea Salt.

  • Pipers lists nutrition per 100g for the named flavour, including 4.8g protein.
  • The same label lists 1.6g salt per 100g; compare the portion on the pack before choosing it for elevenses.

REAL Hand Cooked Crisps

A potato-crisp range whose Sea Salt flavour has stated per-100g nutrition.

  • REAL lists 5.6g protein and 1.3g salt per 100g for Sea Salt.
  • REAL describes its range as vegetarian and gluten-free; check the exact pack for ingredients and allergen information relevant to you.

Questions about protein and crisps

Does protein on a potato-crisp label mean it is high protein?

No. Regulation (EC) No 1924/2006 states that a high-protein claim requires at least 20% of the food’s energy to come from protein. As a named example, KETTLE Chips lists 8.0g protein and 514 kcal per 100g for Vegan Sheese & Red Onion potato crisps, which works out at about 6.2% of energy from protein.

Should I compare protein per bag or per 100g?

Start with the bag or serving you expect to eat at elevenses; use per-100g values when comparing products of different sizes. A larger per-100g figure does not, by itself, tell you how many grams of protein your portion provides.

Are lentil crisps necessarily high protein?

No. Tyrrells lists 14g protein and 462 kcal per 100g for Sour Cream & Onion Lentil Crisps. About 12.1% of their energy comes from protein, meeting the separate 12% source-of-protein threshold stated in Regulation (EC) No 1924/2006 but not its 20% high-protein threshold.

What should I check if an ingredient or allergen matters?

Read the ingredients and allergen information for the exact flavour and pack. The Food Standards Agency says allergens in prepacked food must be emphasised in the ingredients list; Seabrook’s Cream Cheese & Chive crisps, for example, list whey powder (milk).

Does salt still matter when comparing crisps for protein?

Yes, if salt is part of your buying decision, compare it for the portion you will eat rather than judging a product by protein alone. Walkers lists 0.34g salt per 25g for Ready Salted, while Pipers lists 1.6g per 100g for Karnataka Black Pepper & Sea Salt; check pack sizes before comparing those figures.
