If protein from the snack is your priority, compare protein per packet and consider a protein-focused crisp alternative: EatProtein lists 11.2g per bag for its Cheese & Onion and Barbecue varieties, while Walkers Ready Salted lists 2g per 32.5g serving and Seabrook Sea Salted lists 1.9g per bag. If you specifically want potato crisps, choose them as a side to lunch rather than relying on them for protein; a lentil crisp offers another route, but it is not a potato crisp and its ingredients and allergens need checking.
If you want the packet itself to contribute a substantial amount of protein, compare protein-focused crisp alternatives by the amount per bag. Check the ingredients and allergens of the flavour you intend to buy.
If a familiar potato crisp is what you want alongside a sandwich, salad or wrap, keep its protein contribution in perspective. Walkers lists 2g per 32.5g serving of Ready Salted; Seabrook lists 1.9g per 31.8g bag of Sea Salted.
A lentil-based snack offers a different ingredient base. Tyrrells lists 3.9g protein per 30g serving of Sour Cream & Onion Lentil Crisps, compared with the smaller amounts in the potato-crisp servings above. Check the exact flavour for allergens.
Start with the ingredient base you actually want, then compare the amount in the packet or portion you would take to lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Compare grams of protein per bag or stated serving, as well as per 100g. Check whether a sharing pack needs portioning. | I want to know what the portion I take for lunch contributes, not just what the per-100g figure says. |
| Ingredient base | Read the ingredient list to distinguish potato crisps from lentil-based and protein-focused crisp-style snacks. Check the allergen statement for the exact flavour. | Potato flavour and texture may matter more to me than choosing a snack made from a different base. |
| Packet size | Compare a single bag with the amount you would portion from a larger pack. Read nutrition values on the same serving basis. | I need a portion I can carry with lunch without mistaking the whole pack for one serving. |
| Salt and other nutrition | Read salt per packet and per 100g alongside protein, energy and fat. Nidirect identifies more than 1.5g salt per 100g as high; Tyrrells lists 0.60g salt per 30g serving of Sour Cream & Onion Lentil Crisps. | If I regularly pack crisps, I want to compare the salt in the portion I would eat, rather than choosing by a reduced-fat claim alone. |
Containing some protein is different from qualifying for a high-protein claim. The threshold published by legislation.gov.uk is at least 20% of a food’s energy from protein; the stated protein in the Walkers and Seabrook potato-crisp servings is around 2g.
If protein is your main reason for buying the snack, compare the exact pack’s protein and energy values rather than relying on the word “crisps”.
The alternative routes have different ingredient bases, which matters if you are buying specifically for a conventional potato crisp or need to avoid an ingredient.
Decide whether potato is essential, then read the ingredient and allergen statements for the flavour you choose.
Fat and protein describe different parts of the nutrition panel. Walkers markets Oven Baked Sea Salt as lower in fat than regular potato crisps, while listing 1.3g protein per 22g pack.
Compare protein per pack separately from energy, fat and salt.
Packet size alone does not tell you its salt content. Tyrrells lists 0.60g salt per 30g serving of Sour Cream & Onion Lentil Crisps.
Use both the per-serving and per-100g figures when comparing flavours or pack sizes.
Its Ready Salted potato crisps and Oven Baked Sea Salt snacks offer familiar potato-based options for a lunch side.
Its potato crisps and separate lentil-crisp line serve different ingredient preferences.
Lightly Salted is a conventional potato-crisp option when the potato-crisp experience matters more than protein per portion.
Sea Salted is a conventional potato-crisp option with nutrition stated for a single bag.
Pipers describes its range as potato crisps with a variety of seasonings.
REAL presents a hand-cooked crisp range and states that the range is vegetarian and gluten-free.
These options include a lentil cake, lentil chips and potato crisps. Check the type and pack size before treating any one of them as a substitute for another in your packed lunch.

Consider these if you are open to a lentil cake rather than a potato crisp. The pack is 100g; compare its on-pack protein per portion and allergen statement with your lunch needs.

These are a lentil-chip option if you are willing to choose a non-potato snack. The pack is 95g; compare protein and salt for the portion you plan to take.

A potato-chip option for the side of a portable lunch. The 60g pack has an egg-yolk flavour; check its ingredients and nutrition panel if allergens or protein per portion affect your choice.

Choose this 55g potato-chip pack if you want a spicy crisp alongside lunch. Compare its protein and salt per pack with any alternative you are considering.

These potato crisps suit a lunch where the conventional crisp is a side, rather than the planned protein component. The 150g pack can be portioned before you leave; check nutrition values for the amount you take.
Do not assume so from the ingredient or a per-100g protein figure. Legislation.gov.uk states that a high-protein claim requires at least 20% of the food’s energy to come from protein; Walkers Ready Salted lists 2g per 32.5g serving and Seabrook Sea Salted lists 1.9g per 31.8g bag. Check the nutrition panel of the exact pack you buy.
A protein figure describes one part of the packet’s nutrition, not a complete lunch. The NHS Eatwell Guide considers the balance of food groups over a day or week, so think about the snack alongside the other food you are packing.
Read the ingredient and allergen statement on the exact flavour and pack before choosing a potato, lentil or protein-focused crisp alternative. Their ingredient bases differ, and a statement for one flavour should not be applied to another.
Use salt per 100g to compare products, then salt per packet or intended portion to see what you would eat. Nidirect identifies more than 1.5g salt per 100g as high; Tyrrells lists 0.60g per 30g serving of Sour Cream & Onion Lentil Crisps.
Not necessarily: reduced fat and protein are separate nutrition measures. Walkers markets Oven Baked Sea Salt as lower in fat than regular potato crisps, but lists 1.3g protein per 22g pack. Compare both figures on the pack rather than using one claim to infer the other.
