Parents packing primary-school lunchboxes
Individual portions can make packing straightforward, but fat is only one figure to check. Salt, allergens and the school’s packed-lunch policy also matter for the particular child and school.
Who is choosing?
Families switching from standard crisp multipacks
Compare fat per 100g on the products themselves. “Lightly salted”, hand-cooked and vegetable-based describe different attributes; none establishes that a crisp is reduced in fat.
Vegetarian or vegan snack shoppers
Check dietary declarations for the exact flavour alongside its nutrition panel and allergen statement. A vegetarian or vegan label does not describe the product’s fat content.
What matters when comparing crisps?
Start with fat per 100g to compare products of different sizes, then look at what one lunchbox portion contains. Read salt and allergen information as separate checks.
| Priority | What to check | Your needs |
|---|---|---|
| Fat comparison | Compare fat per 100g, then read what any reduced-fat claim is measured against. Walkers UK lists 13g per 100g for Oven Baked Sea Salt and 31g per 100g for Ready Salted; Tyrrells lists 18g per 100g for Sweet Chilli & Red Pepper Lentil Crisps. | I want to know whether the crisp I’m buying has less fat than my usual one, rather than relying on the flavour or cooking description. |
| Salt and labels | Read salt separately from fat and compare like-for-like per 100g values. Walkers UK lists 0.85g salt per 100g for Oven Baked Sea Salt, while its Lightly Salted line lists 31g fat per 100g despite its less-salt claim. | I want to compare the whole nutrition label, not just the reduced-fat wording. In the Food Standards Agency and Ipsos Northern Ireland’s 2024 survey of 611 people interviewed in Northern Ireland, 49% said they actively used traffic-light labelling when shopping for food. |
| Pack size | Check both the pack weight and the nutrition values for that portion. Walkers UK lists 96 kcal for a 22g Oven Baked Sea Salt pack; Simply Roasted lists 91 kcal for a 21.5g Sea Salt serving. | A single pack is convenient for my lunchbox; if I choose a larger bag, I want to decide on the portion before packing it. |
| Allergens and diet | Read the ingredients, may-contain advice and dietary declaration on the exact flavour. Tyrrells states that its Sweet Chilli & Red Pepper Lentil Crisps may contain soya and gluten. | If an ingredient or dietary restriction matters in my household, I need the current pack’s information rather than a brand-wide assumption. |
| School policy | Check the individual school’s packed-lunch policy before choosing crisps for school. Do not assume that guidance about food provided by schools sets the rules for every home-packed lunch. | I want to know whether this snack fits my child’s school policy before buying a multipack for lunchboxes. |
Common buying mistakes
-
Reading “lightly salted” as “reduced fat”
Salt and fat are separate measures. Walkers UK lists 31g fat per 100g for Lightly Salted and 13g per 100g for Oven Baked Sea Salt.
Decide which measure you want to change, then compare the relevant per-100g figures and the portion you intend to pack.
-
Assuming vegetable crisps contain less fat
REAL Hand Cooked Crisps lists 28.0g fat per 100g for Veg Crisps. The vegetable ingredients do not tell you the finished crisp’s fat content.
Use the nutrition panel to compare them with a specific baked, roasted or standard potato crisp.
-
Overlooking the portion
Values per 100g help compare products, but the amount packed determines the serving. Walkers Oven Baked Sea Salt comes in 22g packs; Tyrrells gives nutrition values for a 30g serving of its lentil crisps.
Check the weight of the pack you plan to send, especially if it is not an individual portion.
-
Treating reduced-fat crisps as a replacement for other snacks
A lower fat figure does not describe every aspect of a snack. NHS Healthier Families recommends fruit and vegetable snacks for children and advises paying attention to traffic-light labels when choosing packaged snacks.
Consider where crisps fit in the lunchbox alongside the other food being packed, rather than choosing on the fat claim alone.
Brand and product-line references
These distinctions concern the named product lines, not every crisp made by each brand.
Walkers
Oven Baked is the relevant line for Walkers’ reduced-fat comparison; Lightly Salted makes a salt-reduction claim instead.
- Walkers UK lists 13g fat per 100g and 96 kcal per 22g pack for Oven Baked Sea Salt, and claims 50% less fat than regular potato crisps.
- Walkers Lightly Salted lists 31g fat per 100g, so its less-salt claim should not be read as a less-fat claim.
Tyrrells
The Sweet Chilli & Red Pepper Lentil Crisps provide a lentil-based choice with a manufacturer reduced-fat comparison.
- Tyrrells claims 30% less fat than standard potato crisps on average and lists 18g fat per 100g for this product.
- The product may contain soya and gluten; its chilli seasoning is also worth considering for the intended lunchbox.
Simply Roasted
Its Sea Salt nutrition values offer another specific crisp to compare when fat per 100g and serving size matter.
- Simply Roasted lists 13.9g fat and 0.76g salt per 100g, with 91 kcal per 21.5g serving.
- Check the pack format you intend to buy rather than treating the stated serving as the weight of every pack.
KETTLE Chips
Lightly Salted is a flavour description, not a reduced-fat claim.
- KETTLE Chips states that Lightly Salted is suitable for vegans and vegetarians.
- It lists 29.5g fat per 100g; compare that figure directly if reducing fat is the aim.
Seabrook
Sea Salted is a crinkle-cut potato crisp to assess by its own nutrition values, rather than its dietary declarations.
- Seabrook declares Sea Salted gluten-free and suitable for vegetarians and vegans.
- It lists 30.4g fat and 1.3g salt per 100g; those dietary declarations do not establish reduced fat.
REAL Hand Cooked Crisps
Veg Crisps contain vegetable ingredients, but their nutrition values determine whether they fit a fat-reduction comparison.
- REAL states that Veg Crisps are suitable for vegetarians and vegans.
- Veg Crisps list 28.0g fat per 100g; do not infer a reduced-fat choice from the vegetable name.

Questions about lunchbox crisps
Does reduced fat mean less salt?
No. Compare salt separately for the specific products: Walkers UK lists 13g fat and 0.85g salt per 100g for Oven Baked Sea Salt, while its Lightly Salted crisps list 31g fat per 100g despite a less-salt claim.
Can I put reduced-fat crisps in a school packed lunch?
Check the individual school’s packed-lunch policy before buying them for school. The Department for Education’s school-food guidance addresses food and drink provided in state-funded schools in England; it does not establish a single rule for home-packed lunches throughout the UK.
Can reduced-fat crisps replace other school snacks every day?
A reduced-fat claim alone is not a reason to replace other snacks. NHS Healthier Families favours fruit and vegetable snacks for children and advises aiming for no more than two packaged snacks a day; it also recommends checking traffic-light labels when choosing packaged options.
What if my child has an allergy or follows a particular diet?
Read the current label for the exact flavour before packing it. Tyrrells states that its Sweet Chilli & Red Pepper Lentil Crisps may contain soya and gluten; a brand name or vegetarian declaration cannot replace a product-specific allergen check.
