People packing lunch to go
If you plan to take one packet, compare calories for that packet rather than relying on the per 100g figure. Check whether a larger bag needs portioning before you leave.
Who is this choice for?
Shoppers who specifically want maize
Check the ingredients, not just the puffed shape. Walkers UK lists potato starch first for Quavers Cheese, while its listed Monster Munch Pickled Onion, Sweet & Spicy and Wotsits Really Cheesy products list maize first.
People checking dietary labels
If vegan or free-from labelling matters to your choice, read it for the exact product and flavour. Tesco labels its Free From Cheese Balls as suitable for vegans and free from milk, wheat and gluten; check the current pack before buying.
What should you compare?
Start with the amount you expect to eat at lunch, then check the ingredient base and the rest of the label.
| Priority | What to check | Your needs |
|---|---|---|
| Pack calories | Read the kcal figure for the stated pack or portion and its weight in grams. Walkers UK lists 98 kcal per 20g pack for Monster Munch Pickled Onion and Sweet & Spicy; its Wotsits Really Cheesy listing gives 123 kcal per 22.5g serving. | I want to know the calories in the amount I will actually put in my lunch, not just the amount shown per 100g. |
| Nutrition label | Check fat, saturates, sugars and salt alongside calories. GOV.UK explains that traffic-light labels show whether these nutrients are high, medium or low. | I use the traffic-light information to compare more than calories. In a 2024 survey of 611 Northern Ireland adults by the Food Standards Agency and Ipsos Northern Ireland, 49% said they actively used traffic-light labelling when shopping for food; this measures label use, not maize-snack preferences. |
| Ingredients and allergens | Check the first ingredient if maize is essential. Read the current allergen statement for the exact flavour and look for any dietary labels you require. | A puffed snack will not suit my choice if its main ingredient is something other than maize, or if its allergen information conflicts with what I need to avoid. |
| Pack format | Check whether the product comes in individual bags or one larger bag. For a larger bag, use the labelled serving size when comparing calories with single packs. | A separate bag is easier for me to pack as one portion; with a larger bag, I would need to decide how much to take. |
Common buying mistakes
-
Assuming every puffed snack is maize-based
Walkers UK lists Quavers Cheese at 86 kcal per 16g pack, but potato starch is its first ingredient. Its lower pack figure does not make it a strict maize-snack option.
If maize is essential, check the first ingredient on the exact flavour you are buying.
-
Comparing only the per 100g figures
A 16g pack and a 25g portion are different amounts of food. Their per 100g figures do not tell you, on their own, how many calories you would eat at lunch.
Compare the labelled pack or serving weight and its kcal figure, then decide whether that is the amount you intend to eat.
-
Treating ‘baked’ or ‘vegan’ as a calorie comparison
Walkers describes Wotsits Really Cheesy as baked, yet lists 123 kcal per 22.5g serving. Tesco lists 123 kcal for a stated portion of its vegan Free From Cheese Balls. Those descriptions address preparation or dietary suitability, not a shared calorie figure.
Check calories and the nutrition label separately from preparation and dietary claims.
-
Choosing by ingredient base without reading allergens
Being maize-based does not establish that a flavoured snack meets an allergy or free-from requirement. Ingredients and allergen statements differ between products and flavours.
Read the current pack’s ingredients, allergen statement and any relevant free-from wording for the exact product.
Brand and range references
These examples show why it matters to compare exact products and portions rather than relying on a brand name alone.
Monster Munch
Walkers UK lists maize first for its Pickled Onion and Sweet & Spicy flavours, with 98 kcal per 20g pack for each.
- Both listed flavours offer a clearly stated individual pack for comparing lunch portions.
- Check each flavour’s allergen statement; the calorie and ingredient figures here do not establish the details of every Monster Munch variety.
Wotsits
Walkers UK lists maize first for Wotsits Really Cheesy and gives 123 kcal per 22.5g serving.
- The stated serving weight makes it possible to compare this flavour with smaller individual packs.
- Walkers describes it as baked, but that description does not replace a check of calories and salt.
Tesco Free From
Tesco lists Free From Cheese Balls and Onion Maize Snack Rings as vegan options, at 123 kcal and 124 kcal respectively per stated portion.
- Tesco explicitly labels Cheese Balls free from milk, wheat and gluten; check the exact wording for whichever product you choose.
- Their stated portions have higher kcal figures than the two 98-kcal Monster Munch packs above, but portion sizes differ.
Quavers
Walkers UK lists 86 kcal per 16g pack for Quavers Cheese. Its ingredient list starts with potato starch.
- The smaller pack has a lower labelled kcal figure than the maize-based examples above.
- Quavers Cheese does not meet a requirement for maize to be the first ingredient.

Frequently asked questions
Does a pack below 100 kcal settle the lunch-snack choice?
No. The figure describes calories for that stated amount, not its ingredients or other nutrition values. Check the serving weight, fat, saturates, sugars and salt as well; GOV.UK explains that traffic-light labels show these nutrients alongside calories.
Is Quavers Cheese a maize-based choice?
Not if you require maize to be the first ingredient. Walkers UK lists potato starch first for Quavers Cheese, while its listed Monster Munch Pickled Onion, Sweet & Spicy and Wotsits Really Cheesy products list maize first.
Which listed maize snack has vegan and free-from labelling?
Tesco labels its Free From Cheese Balls suitable for vegans and free from milk, wheat and gluten. Tesco also labels its Free From Onion Maize Snack Rings suitable for vegans and gluten-free; check the current pack for every dietary condition you need it to meet.
Should I check the pack when buying snacks online?
Yes. Read the current pack’s serving size, nutrition information, ingredients and allergen statement before relying on them for a lunch choice, particularly when comparing different flavours or following a dietary restriction.
