People following a strict keto plan
If carbohydrate intake needs to remain very low, check the amount in the pack or serving you intend to eat. The familiar snacks covered here contain substantial carbohydrate per 100g, even where the pack is small.
Who needs to check the label?
Snackers comparing protein
Cheese flavour, baking or chickpea flour does not tell you how much protein a snack provides. Compare the nutrition figures on the same per-100g basis, then look at the amount in one pack.
Buyers checking allergens
Cheese- and bacon-flavoured snacks can contain milk or soya ingredients, while individual packs may carry warnings for other allergens. Check the statement on the exact product before buying or eating it.
What matters when choosing?
Choose another snack type
When: Choose this route if a standard maize snack would use too much of your carbohydrate allowance.
Trade-off: A different snack will not necessarily give you the same puffed-maize texture; check its own nutrition label rather than assuming it fits.
Keep an occasional maize snack
When: Choose the flavour and portion you want only after checking that its carbohydrate amount fits your plan.
Trade-off: A smaller pack changes the amount eaten, not the product’s carbohydrate content per 100g.
Compare products per 100g first, then use the pack or serving figure to judge the amount you would actually eat.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Read total carbohydrate per 100g and per pack or serving. Do not use the sugar figure alone to judge a maize snack. | For a very low-carbohydrate plan, I need to know how much of my allowance the portion would use. |
| Protein | Compare protein per 100g on the same basis, then check the amount per pack. Walkers UK lists 8.0g protein and 64.2g carbohydrate per 100g for Wotsits Cheese Toastie. | I want to compare protein without mistaking a comparatively higher figure among maize snacks for a keto-suitable choice. |
| Portion size | Check the weight of a single pack and whether a sharing pack contains more than one serving. Walkers UK lists 12g carbohydrate in a 20g Monster Munch Pickled Onion pack. | A small pack may help me measure what I eat, but I still need its carbohydrate figure. |
| Allergens and salt | Read the current ingredients and may-contain statement for the exact flavour. Compare salt for the serving you expect to eat, not just per 100g. | If I avoid particular allergens or monitor salt, I need figures and warnings for the pack I choose. |
Common buying mistakes
-
Treating “baked” or chickpea ingredients as a keto test
Walkers UK lists 64.2g carbohydrate per 100g for Wotsits Cheese Toastie. Its processing style or ingredients cannot replace the nutrition figure.
Compare carbohydrate and protein per 100g, then check the amount in the pack you intend to eat.
-
Choosing by protein alone
Wotsits Cheese Toastie has the highest protein figure among the examples compared here, at 8.0g per 100g, but Walkers UK also lists 64.2g carbohydrate per 100g.
Check whether the carbohydrate in your portion fits your plan before using protein to distinguish between maize snacks.
-
Overlooking the allergen statement
A snack being vegetarian does not rule out milk or soya ingredients, or warnings about cereals containing gluten and other allergens.
Read the statement on the current pack, particularly if its packaging or recipe has changed.
-
Assuming a small pack needs no calculation
Walkers UK lists 12g carbohydrate in a 20g Monster Munch Pickled Onion pack; the Tesco Groceries listing for a 20g Frazzles pack also gives 12g. Portion size matters even when the bag looks small.
Use the per-pack or per-serving figures for the amount you expect to eat, including its carbohydrate and salt.

Questions about maize snacks and keto
Are ordinary maize snacks suitable for a strict keto plan?
The examples checked are difficult to fit into a very low-carbohydrate plan: Walkers UK and Tesco Groceries list 56–65.2g carbohydrate per 100g across these products. Check the carbohydrate in the portion you would eat against your own plan rather than relying on words such as “baked” or “cheese”.
Which of the compared snacks has the most protein?
Wotsits Cheese Toastie has the highest protein figure among the products compared here, at 8.0g per 100g, according to Walkers UK. It also has 64.2g carbohydrate per 100g, so that protein figure alone does not establish keto suitability.
What allergens should I check in flavoured maize snacks?
Check the current label of the exact product for ingredients and may-contain statements. The named examples include milk or soya ingredients, while some carry warnings for wheat, barley, gluten, celery or mustard; the warnings differ by product.
Can I rely on an online nutrition panel?
Use an online panel to compare products, then check the pack you receive before eating it. Tesco Groceries notes that recipes, nutrition and allergen information can change.
