Students planning dinner on a limited budget
If protein matters to the meal, decide on its main protein food before adding crisps as an optional side.
Who is this decision for?
Shoppers comparing crisp labels
A larger protein number than another crisp does not, by itself, establish that a product meets the high-protein claim criterion. Compare protein and energy on the same basis.
Students checking dietary suitability
Ingredients and precautionary allergen statements can differ between flavours. Check the exact pack rather than relying on the brand name.
What should you check?
Start with the dinner’s protein food; if you also want crisps, compare the portion you will eat and the label for that exact flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Protein contribution | Compare protein grams and energy from the same per-100g or per-serving column. Regulation (EU) No 1169/2011 gives 4 kcal per gram of protein; the high-protein claim criterion in Regulation (EC) No 1924/2006 is at least 20% of energy from protein. | I need the dinner’s protein to come from a protein food, rather than counting on a small difference between ordinary crisps. Beans, pulses, eggs and tofu are among the protein foods listed by Kent Community Health NHS Foundation Trust. |
| Portion and nutrition | Check pack weight and the declared serving size. Compare protein, energy, fat and salt per serving as well as per 100g; a reduced-fat description does not tell you the protein content. | I want to know what the portion I will actually eat contributes. In the Food Standards Agency and Ipsos Northern Ireland’s 2024 tracker, 49% of 611 people interviewed in Northern Ireland between 16 September and 23 November actively used traffic-light labelling when shopping for food; that figure does not describe student crisp purchases. |
| Ingredients and allergens | Read the exact flavour’s ingredients, highlighted allergens, suitability statements and any ‘may contain’ warning. Check the current pack if the recipe or flavour changes. | For a dietary restriction or allergy, I need information for this particular pack, not an assumption about everything the brand makes. |
Common buying mistakes
-
Calling the crisp with the largest protein number ‘high protein’
REAL Hand Cooked Crisps declares 7.7g protein and 496 kcal per 100g for Roast Ox. Using the 4 kcal-per-gram conversion factor in Regulation (EU) No 1169/2011, protein accounts for about 6.2% of its energy—not the 20% in the high-protein claim criterion.
Use protein and energy figures from the same part of the nutrition panel. Calculate protein grams × 4 kcal ÷ total kcal if you need to assess the energy share.
-
Treating ‘reduced fat’ as a protein claim
Walkers describes Oven Baked Sea Salt as having 50% less fat than regular potato crisps, but its declared 22g pack contains 1.3g protein. The fat comparison answers a different question.
Choose the meal’s protein food separately, and compare fat, salt and protein on their own terms when selecting a crisp side.
-
Assuming a brand’s flavours share an allergen profile
Tyrrells Lightly Sea Salted carries a ‘may contain Milk’ statement, while REAL Roast Ox lists lactose, soya and celery in its ingredient and allergen information.
Read the ingredients and precautionary wording on the exact flavour and pack you intend to eat.
Brand and product-line references
These examples show why a brand name or a claim about fat is not enough to judge protein content; figures and suitability statements belong to the named products.
Walkers
The range includes standard potato crisps and Oven Baked products.
- Walkers declares 1.3g protein per 22g pack for Oven Baked Sea Salt.
- Its ‘50% less fat than regular potato crisps’ description is not a protein claim. Check each flavour’s allergen information separately.
Tyrrells
Its potato-crisp range includes Lightly Sea Salted.
- Tyrrells declares 6.9g protein per 100g for Lightly Sea Salted.
- That product carries a ‘may contain Milk’ statement. Tyrrells lentil crisps are a different product category from potato crisps.
KETTLE Chips
Lightly Salted is a potato-crisp product that KETTLE Chips describes as suitable for vegans and vegetarians.
- Its declared per-100g values include 6.5g protein, 516 kcal and 0.7g salt.
- Dietary suitability does not establish that the product meets the high-protein claim criterion.
Seabrook
The range includes flavoured potato crisps such as Lea & Perrins.
- Seabrook declares 5.6g protein and 505 kcal per 100g for Lea & Perrins crisps.
- The gluten-free, vegetarian and vegan descriptions supplied for that flavour should not be assumed to apply to every Seabrook product.
Pipers
Pipers describes a range of potato crisps with different flavourings.
- The range offers a choice of flavours for shoppers who want crisps as a side.
- Judge protein contribution using the nutrition panel for the exact product and portion.
REAL Hand Cooked Crisps
The range includes flavoured potato crisps such as Roast Ox.
- REAL declares 7.7g protein per 100g for Roast Ox.
- The Roast Ox ingredient and allergen information lists lactose, soya and celery. Its protein figure alone does not make it a high-protein food.
Potato crisps for an optional side
These Joybuy potato-crisp options are for a side alongside a student dinner, not for replacing the meal’s protein food. Check the current pack when comparing portions, ingredients and nutrition.

Questions about protein and crisps
What does ‘high in protein’ mean on a food label?
The high-protein claim criterion in Regulation (EC) No 1924/2006 is that protein provides at least 20% of the food’s energy. Regulation (EU) No 1169/2011 gives a conversion factor of 4 kcal per gram of protein, so use protein and energy figures from the same per-100g or per-serving column when checking a label.
Are the named potato crisps in this article high in protein?
The sampled products from Walkers, KETTLE Chips, Tyrrells, Seabrook and REAL Hand Cooked Crisps do not reach the 20%-of-energy high-protein claim criterion. Calculations from those brands’ declared protein and energy values, using the conversion factor in Regulation (EU) No 1169/2011, put the sampled products at approximately 4.4% to 6.2%. That conclusion applies to those named products, not every potato crisp.
Where do crisps fit in a student dinner if protein matters?
Use potato crisps as an optional side rather than the meal’s protein food. Kent Community Health NHS Foundation Trust lists foods including beans, pulses, eggs, fish, dairy and tofu as protein sources; choose the meal’s main food first, then decide whether you want a crisp portion alongside it.
Does a reduced-fat crisp provide more protein?
A reduced-fat description does not establish protein content. Walkers describes Oven Baked Sea Salt as 50% less fat than regular potato crisps, while declaring 1.3g protein per 22g pack. Check protein and the portion size separately from any fat claim.
Which allergen information should I check on crisps?
Check the exact pack’s ingredients, highlighted allergens and precautionary statements. For example, Tyrrells labels Lightly Sea Salted ‘may contain Milk’, while REAL lists lactose, soya and celery for Roast Ox; another flavour from either brand may have different information.
