Compare total fat per 100g before choosing a bag size: the five maize-containing puffs and rings compared using Walkers UK and Tesco Groceries labels have 18.1g to 25g of fat per 100g, while the NHS defines low fat as 3g or less per 100g. For a late-night portion, check the amount you expect to eat, then compare salt and the exact ingredients; a baked or free-from label does not answer the fat question.
The useful starting point depends on whether fat content, a single-bag portion or an ingredient restriction drives your choice.
If you want a maize-containing savoury snack, compare total fat per 100g before deciding whether a small pack meets your intended portion. Lower in fat than another snack does not necessarily mean low fat under NHS label guidance.
A single bag gives you a stated serving size. Check its fat, salt and calorie figures alongside the per-100g panel, particularly when comparing bags of different sizes.
Read the declaration for the exact flavour if milk, gluten or another ingredient matters to you. A free-from statement describes specified ingredients or dietary suitability, not the product’s fat content.
Use the per-100g panel to compare products on the same basis, then use the pack figures to decide how much you plan to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare total fat per 100g. The NHS defines low fat as 3g or less and high fat as more than 17.5g per 100g. Walkers UK lists Wotsits Cheese Toastie at 18.1g per 100g. | I want to compare fat on the same basis, even if the snack comes in a small bag or is described as baked. |
| Portion size | Check the weight of the bag and its per-bag figures against the amount you expect to eat. Tesco Groceries lists Wotsits WOW Lightly Salted at 72kcal and 3.1g fat per 15g bag, but 21g fat per 100g. | A single bag may suit my late-night plans, but I do not want its smaller total to obscure the per-100g comparison. |
| Salt | Compare salt per 100g as well as per bag. Walkers UK lists 0.81g per 100g for Wotsits Cheese Toastie and 1.55g for Monster Munch Pickled Onion; the NHS classifies more than 1.5g per 100g as high. | If two snacks differ in fat, I also want to see how their salt figures compare before choosing. |
| Ingredients | Read the ingredient list and allergen declaration for the exact flavour. Walkers UK lists chickpea flour and maize in Wotsits Cheese Toastie; Tesco Groceries labels its Free From Onion Maize Snack Rings vegan, gluten free, wheat free and milk free. | Maize needs to be an ingredient, and any dietary exclusions need checking on the pack I choose. |
Tesco Groceries describes Wotsits WOW Lightly Salted as baked and lists 72kcal per 15g bag, but its total fat is 21g per 100g. That exceeds the NHS high-fat threshold of more than 17.5g per 100g.
Use the cooking description to identify the product, not to classify its fat content. Check total fat per 100g separately.
A smaller bag contains less food, so its per-bag fat figure does not show whether the snack itself has less fat than a larger bag.
Shortlist using fat and salt per 100g, then compare the stated serving sizes with the amount you intend to eat.
Tesco Groceries labels its Free From Onion Maize Snack Rings vegan, gluten free, wheat free and milk free. It also lists 23.9g fat per 100g, above the NHS high-fat threshold.
Use the dietary declaration for the exclusion it names, and check the nutrition panel separately for fat and salt.
Walkers UK lists potato starch first in the ingredients for Quavers Cheese. A similar shape does not establish that a snack is made from maize.
If maize is essential to your choice, confirm that maize or corn appears in the ingredients for the exact product.
These examples show why the exact recipe and flavour matter more than a brand name alone.
The named range includes Cheese Toastie chickpea-and-maize snacks and WOW corn, chickpea and rice puffs, as well as standard cheese puffs.
Walkers UK lists maize first in the ingredients for the Pickled Onion snack.
Tesco Free From Onion Maize Snack Rings are described as baked maize snacks and labelled vegan, gluten free, wheat free and milk free.
Quavers Cheese is a puffed savoury snack to distinguish from maize-based recipes, rather than a maize example.
These corn-based options include crunchy corn snacks, toddler corn puffs and popcorn. They are different formats, so check each pack’s nutrition and ingredient information against the late-night portion you want.

The 115g bag is a larger format than the single-pack options shown here. If you want a smaller late-night portion, decide how much to serve and use the per-100g panel to compare fat and salt.

This habanero variety comes in ten 45g packs. If its flavour and pack size suit your plans, check both fat and salt per 100g rather than choosing by flavour or portion size alone.

This is popcorn rather than a shaped maize puff or ring, with six stated 10g bags. Use its own nutrition panel when comparing the per-100g figures and the amount in one bag.
No. The NHS defines low fat as 3g or less per 100g, so check the nutrition panel rather than the cooking description. Tesco Groceries describes Wotsits WOW Lightly Salted as baked and lists 21g fat per 100g.
Start with total fat and salt per 100g so different pack sizes are comparable. Then check the stated serving size and its per-bag figures against the amount you expect to eat; NHS guidance notes that a manufacturer’s portion may differ from yours.
No. Walkers UK lists 18.1g fat per 100g for Wotsits Cheese Toastie, above the NHS high-fat threshold of more than 17.5g per 100g. Its 12g bag contains 2.2g fat and 57kcal; that smaller bag figure does not change the per-100g classification.
No. Check the exact pack’s ingredients, allergen declaration and any precautionary statement. Walkers UK identifies milk in Wotsits Cheese Toastie, whereas Tesco Groceries labels its Free From Onion Maize Snack Rings milk free, wheat free and gluten free.
Not if maize is a required ingredient: Walkers UK lists potato starch first in the Quavers Cheese recipe. Check the ingredient list for maize or corn rather than relying on a puffed shape.
