If protein per snack is the deciding factor, compare purpose-made protein crisps first: Applied Nutrition lists 15g per 50g bag and Myprotein lists 11g per 25g serving, against 3.9g per 30g serving for Tyrrells lentil crisps and 1.7g per 25g pack for Walkers potato crisps. For a convenient savoury snack, lentil or potato crisps may still suit you when flavour or dietary requirements matter more; check salt and allergens on the exact product, and do not treat crisps as a replacement for varied meals.
Who is choosing?
New parents needing a quick savoury snack
A snack that can sit in a cupboard or bag may be convenient during disrupted routines. If you are breastfeeding, NHS guidance recommends eating a variety of foods, including protein foods, rather than relying on a particular snack.
Shoppers comparing protein per portion
Pack size changes the comparison. Applied Nutrition lists 15g protein in a 50g bag and Myprotein lists 11g in a 25g serving; Tyrrells lists 3.9g in a 30g serving of its Sour Cream & Onion Lentil Crisps. Compare the amount you expect to eat, not just a prominent number on the front of a pack.
Parents checking dietary requirements
Ingredients differ even among savoury snacks with similar names. Tyrrells’ Sour Cream & Onion Lentil Crisps contain milk, while Myprotein’s protein crisps contain soya. Check the current label for the exact flavour you intend to buy.
What should you compare?
Decide whether protein per portion is your main reason for buying, then check the nutrition panel, ingredients and pack format for the snack you would actually eat.
Purpose-made protein crisps
Consider when: Protein per pack matters most; Applied Nutrition lists 15g per 50g bag and Myprotein lists 11g per 25g serving.
Trade-off: Check the exact flavour’s salt and ingredients; Myprotein’s listed 25g serving contains 1.40g salt and its ingredients include soya.
Lentil crisps
Consider when: You want a crisp-style snack and protein per portion is less important; Tyrrells lists 3.9g per 30g serving of Sour Cream & Onion Lentil Crisps.
Trade-off: That Tyrrells serving contains milk ingredients and provides less protein than the purpose-made examples above.
Potato crisps
Consider when: A familiar potato crisp or a particular flavour matters more than protein; Walkers lists 1.7g per 25g Cheese & Onion pack.
Trade-off: Dietary suitability varies by product: Walkers Cheese & Onion contains milk ingredients, while Seabrook describes its Sea Salted crisps as vegan.

What to check |
Your needs |
| Protein per portion |
Read the protein figure for the whole pack or stated serving. Note whether a comparison uses 25g, 30g or 50g, rather than treating per-100g figures as amounts in one snack. |
I want to know how much protein I would get from the portion I plan to eat, not just whether the product is described as protein-packed. |
| Nutrition panel |
Check salt, energy and fat for the exact flavour and serving. Use traffic-light labelling, where present, alongside the figures on the nutrition panel. |
I want to compare more than protein before choosing a regular snack. In a 2024 Food Standards Agency and Ipsos Northern Ireland survey of 611 people interviewed there, 49% actively used traffic-light labelling when shopping for food; this measures label use, not demand for protein crisps. |
| Ingredients and allergens |
Check the current ingredient list, emphasised allergens and any “may contain” statement for the exact flavour. Do not infer milk, soya or gluten suitability from “lentil” or “protein” in the name. |
If I need to avoid a particular ingredient, the flavour-specific label matters more than the type of crisp. |
| Pack format and purpose |
Check whether the pack is an individual portion or a larger bag, and whether it is practical to take with you. For breastfeeding, NHS guidance recommends a varied diet; Imperial College Healthcare NHS Trust says eating more protein does not increase the protein in breast milk. |
A savoury snack might fit a short break, but I would not buy protein crisps expecting them to change breast-milk protein or replace meals. |
Common buying mistakes
-
Treating all crisp-style snacks as equivalent for protein
The stated portion makes a difference: Applied Nutrition lists 15g per 50g bag, Myprotein 11g per 25g serving, Tyrrells 3.9g per 30g lentil-crisp serving and Walkers 1.7g per 25g potato-crisp pack.
Compare protein for the portion you would eat. Choose a lentil or potato crisp for its other characteristics without assuming it matches a purpose-made protein crisp.
-
Letting a protein claim obscure the salt figure
Myprotein lists 1.40g salt per 25g serving of its Popped Protein Crisps. A protein figure does not describe the rest of the nutrition panel.
Read the salt figure for the exact flavour and portion alongside protein, energy and fat.
-
Assuming one dietary claim covers every ingredient
Tyrrells’ Sour Cream & Onion Lentil Crisps contain milk, and Myprotein’s protein crisps include soya protein. Flavour-specific ingredients and “may contain” statements can affect whether a snack fits your requirements.
Use the current pack’s ingredient and allergen information to check the product you will eat. If you follow an individually prescribed elimination diet, seek advice from your clinician about that diet.
-
Buying extra protein to change breast-milk protein
Imperial College Healthcare NHS Trust states that eating more protein does not result in more protein in breast milk.
Choose crisps according to your own snack preferences, not for that expected effect. For breastfeeding diet questions, use NHS guidance or speak to a GP, midwife or health visitor.
Relevant brand references
These named products provide points of comparison for protein per portion and dietary checks; the figures and ingredients apply to the specified products, not every flavour in a brand’s range.
Walkers
A reference point for a small pack of conventional potato crisps.
- Walkers lists 1.7g protein and 0.29g salt per 25g Cheese & Onion pack.
- That flavour contains milk ingredients and may contain wheat, gluten, barley, soya, celery and mustard.
Tyrrells
Its lentil crisps provide a crisp-style option to compare by stated serving.
- Tyrrells lists 3.9g protein per 30g serving of Sour Cream & Onion Lentil Crisps.
- That flavour contains milk and may contain soya and gluten; check other flavours separately.
KETTLE Chips
Lightly Salted is a conventional potato-crisp reference for shoppers checking dietary suitability.
- KETTLE describes Lightly Salted as vegan, vegetarian and gluten-free.
- Its listed protein figure is 6.5g per 100g; check the portion you expect to eat before comparing it with protein per pack elsewhere.
Seabrook
Sea Salted is another conventional crisp with stated vegan and gluten-free suitability.
- Seabrook describes Sea Salted as vegan, vegetarian and gluten-free.
- The brand lists 1.9g protein and 0.4g salt per 31.8g bag, so compare the bag rather than a per-100g figure.
McCoy’s
Salted is a ridged potato crisp to consider for its format rather than a protein-per-pack claim.
- McCoy’s publishes figures for Salted of 6.6g protein and 1.3g salt per 100g.
- The product may contain milk, soya, gluten and mustard; use the pack size and current label for a portion-level comparison.
REAL Hand Cooked Crisps
A conventional crisp range for which flavour-specific ingredients still matter.
- REAL describes its range as vegetarian and gluten-free.
- Its Strong Cheddar & Onion flavour contains milk ingredients and lists 7.6g protein per 100g; check the pack portion for comparison.
Joybuy snack options
These Joybuy options are lentil cakes, lentil chips and a seaweed snack. Compare their pack or serving labels if protein per snack is your main reason for shopping; their names and pack sizes alone do not establish that they match a purpose-made protein crisp.

CJ Bibigo Crispy Seaweed Snack Bulgogi Flavour, 5g × 3
Three 5g packs offer a small-pack savoury snack rather than a potato crisp. Check protein and salt for one 5g pack, not only per 100g, and review the Bulgogi flavour’s ingredients for allergens.

Eat Real Sea Salt Lentil Chips 95g
A 95g bag of lentil chips for shoppers considering a crisp-style snack. Decide how much of the bag you would eat, then compare protein, salt and ingredients for that portion before treating it as an alternative to a single pack of protein crisps.

Questions about crisp snacks
Are protein crisps a new-parent essential?
No particular crisp is necessary for a new-parent diet, but a protein crisp can be a convenient savoury snack if its protein per portion is what you want. NHS guidance for breastfeeding recommends a variety of foods, including protein foods, rather than a special snack or diet.
Will eating more protein crisps increase protein in breast milk?
Do not buy protein crisps for that purpose. Imperial College Healthcare NHS Trust states that eating more protein does not result in more protein in breast milk.
How do I compare protein across crisp snacks?
Compare the amount in the pack or serving you intend to eat. Applied Nutrition lists 15g per 50g bag, Myprotein 11g per 25g serving, Tyrrells 3.9g per 30g lentil-crisp serving and Walkers 1.7g per 25g potato-crisp pack; those are different portion sizes, not interchangeable per-100g figures.
What if I need to avoid milk, soya or another allergen?
Check the ingredient list and allergen statement on the current pack of the exact flavour. Tyrrells’ Sour Cream & Onion Lentil Crisps contain milk, while Myprotein’s protein crisps include soya protein. GOV.UK guidance says the allergens required to be declared in pre-packed food ingredient lists must be emphasised.
