People managing diabetes
Diabetes UK advises looking at total carbohydrate and portion size rather than treating a low sugars figure or a ‘diabetic’ label as a shortcut.
Who needs to check what?
Shoppers avoiding gluten, wheat or milk
Look for a declaration covering the exact restriction, then read the ingredients and allergen information for the flavour and pack you intend to buy. A maize-based snack is not automatically free from these ingredients.
People who count carbohydrate
Use the carbohydrate figure for the amount you intend to eat. Diabetes UK notes that insulin-to-carbohydrate ratios differ between individuals, so a snack label cannot supply a personal insulin dose.
What to check before buying
Check the dietary exclusion and the nutrition information as separate parts of the decision. Compare carbohydrate figures using the same portion size before deciding how much to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Total carbohydrate | Find total carbohydrate on the nutrition label, per 100g or per portion. Compare equal amounts and account for the quantity eaten; the sugars figure is not a substitute. | I want to know the carbohydrate in my actual serving. Tesco Groceries lists 15.3g, 15.9g and 16.1g per 25g portion for its Free From Cool Flavour Tortilla Chips, Onion Maize Snack Rings and Cheese Balls respectively. |
| Allergen declarations | Check the exact product’s gluten-, wheat- and milk-free declarations against the current ingredients and allergen statement. Recheck when changing flavour. | If I need to avoid a particular ingredient, I need a declaration that covers it. Tesco Groceries declares the three named Free From products gluten free, wheat free and milk free; that does not describe every maize snack. |
| Portion size | Distinguish the pack size from the serving used on the nutrition panel. Use the figures for the amount you plan to eat. | A sharing bag may last several servings, so I want to portion out the amount I eat rather than treat the whole bag as one stated serving. |
| Other label values | Compare salt and saturates at the same serving size, alongside carbohydrate. Read traffic-light labelling for what it reports, not as a measure of total carbohydrate. | I want to compare savoury snacks without overlooking salt or assuming a low sugars traffic light tells me their carbohydrate content. |
Common buying mistakes
-
Using ‘of which sugars’ instead of total carbohydrate
Diabetes UK distinguishes total carbohydrate from the sugars figure. A low sugars figure does not tell you how much total carbohydrate a maize snack contains.
Read total carbohydrate on the nutrition panel and calculate it for the portion you intend to eat.
-
Assuming a maize snack is free from other ingredients
Walkers UK lists milk, barley and wheat for Quavers Cheese, wheat and soya in Wotsits Sweet & Spicy flavouring, and milk- and soya-derived ingredients in Monster Munch Pickled Onion.
Check the current ingredient and allergen statement for each exact product and flavour against your restriction.
-
Treating ‘free from’ as a carbohydrate claim
A free-from declaration addresses the specified ingredients, not the snack’s carbohydrate content. Tesco Groceries lists carbohydrate in each stated 25g portion of its three named Free From snacks.
Use the declaration to check your dietary exclusion, then assess carbohydrate and portion size separately.
-
Confusing a sharing bag with one serving
Tesco Groceries lists 150g or 200g packs for the three named Free From products, while their carbohydrate figures are stated per 25g portion. Eating a different amount changes the carbohydrate amount to account for.
Portion out the snack and use the nutrition figures for the amount eaten.
Brand and range references
Tesco Free From
Tesco Groceries declares its Cool Flavour Tortilla Chips, Onion Maize Snack Rings and Cheese Balls gluten free, wheat free and milk free.
- The named products list 15.3g, 15.9g and 16.1g carbohydrate respectively per stated 25g portion.
- Check the current pack for the precise product and serving you buy; a free-from declaration does not make the snack carbohydrate-free.
Wotsits
Ingredients vary by flavour, so Wotsits should not be treated as a free-from range.
- Walkers UK lists 9.6g carbohydrate for the stated 16g portion of Wotsits Sweet & Spicy.
- The Sweet & Spicy flavouring contains wheat and soya. Its 16g serving is not directly comparable with a 25g serving.
Quavers
Walkers UK’s information for Quavers Cheese is relevant to that flavour, not to every snack bearing the brand.
- Its stated 16g portion lists 9.9g carbohydrate and 0.34g salt.
- The Cheese variety lists milk, barley and wheat in its allergen information.
Monster Munch
Check the flavour-specific ingredients rather than assuming a maize snack meets a free-from requirement.
- Walkers UK lists 12g carbohydrate and 0.31g salt for a 20g pack of Monster Munch Pickled Onion.
- Pickled Onion includes milk-derived whey permeate and hydrolysed soya protein.

Questions about maize snacks
Does a low sugars figure make a maize snack suitable when managing diabetes?
Not on its own. Diabetes UK advises checking total carbohydrate, which is separate from the sugars figure, and accounting for the portion actually eaten. Find total carbohydrate on the nutrition panel rather than relying on the front-of-pack sugars traffic light.
Which named maize snacks are declared free from gluten, wheat and milk?
Tesco Groceries declares its Free From Cool Flavour Tortilla Chips, Onion Maize Snack Rings and Cheese Balls free from all three. This applies to those exact products; check the current pack’s ingredients and allergen statement before buying or eating.
Can I assume Quavers, Wotsits or Monster Munch meet a free-from requirement?
No. Walkers UK lists milk, barley and wheat for Quavers Cheese; wheat and soya in Wotsits Sweet & Spicy flavouring; and milk- and soya-derived ingredients in Monster Munch Pickled Onion. Check each exact flavour and current pack against the ingredients you need to avoid.
Why check the pack when a product is described as free from?
The pack identifies the product and provides the ingredient and allergen information to use for the item you have. Check that its declaration covers your particular restriction, especially when choosing a different flavour or pack.
How can someone who counts carbohydrate use the snack label?
Use the labelled carbohydrate figure to work out the amount in the portion eaten. Diabetes UK notes that insulin-to-carbohydrate ratios vary by person; follow your own care team’s instructions rather than deriving an insulin dose from a product comparison.
