What the claim on the front of the pack means, which sweetener is doing the work, and the figures for every Diablo biscuit and wafer

Updated 2026 Diablo figures per 100g from our product specifications
Quick Answer

Which sugar-free biscuits should you buy in the UK?

Start with the Diablo biscuit range, because the claim is stated on every pack and the figure behind it is published per product. The three Sugar Free cookie lines sit at 0.2g of sugars per 100g. The short version:

  • +Diablo SF Chocolate Chip Cookies 130g: 0.2g sugars and 39g carbohydrate per 100g, 462 kcal
  • +Diablo SF Coconut Cookies 150g: 0.2g sugars and 35g carbohydrate per 100g, 463 kcal
  • +Diablo NAS Digestive Cookies 150g: the classic digestive format, 1g sugars, 5g fibre and 17g polyols per 100g
  • +Diablo SF sandwich biscuits 176g: 0.4g sugars per 100g, and both flavours are certified kosher and halal
  • +The buying rule: check whether the pack says sugar free or no added sugar. They are two different claims under GB rules, explained below

Biscuits are a hard aisle to shop carefully, because the front of the pack does most of the talking. Two claims turn up again and again, and they are not interchangeable. Here is what each means, what replaces the sugar, and what the Diablo range measures.

What "sugar free" means on a biscuit pack

Claim on pack What the rules require What that means in the tin
Sugar Free (SF) No more than 0.5g of sugars per 100g The stricter claim. Sweeteners replace the sugar entirely. Diablo SF Chocolate Chip Cookies measure 0.2g per 100g
No Added Sugar (NAS) No sugars added in manufacture. Where sugars occur naturally, that is declared Sugars from ingredients such as milk and wheat remain. Diablo NAS Digestive Cookies measure 1g per 100g
Reduced sugar At least 30 percent less sugars than a comparable product, with energy no higher Still a sugar-containing biscuit, just less of it
Low sugar No more than 5g of sugars per 100g for solid foods A genuinely low figure, but not the same as sugar free

Conditions from assimilated Regulation (EC) No 1924/2006. Diablo figures are per 100g from our product specifications, matched to the exact SKU.

One thing the sugars row will not tell you: total carbohydrate. Biscuits are made of flour, so a sugar free biscuit still carries carbohydrate from the wheat. Read both lines.

All figures per 100g from Diablo product specifications. Where a polyols or fibre figure is not declared on the pack specification, it is marked not declared rather than estimated. On the NAS lines the sugars shown occur naturally in ingredients such as milk and wheat.

The sweetener doing the work

Maltitol is the sweetener across the Diablo biscuit and wafer range. It is used because it behaves like sugar in a dough: it bulks, it browns and it gives a biscuit the snap that intense sweeteners cannot produce on their own. The GB nutrition and health claims register carries one authorised wording for it, worth quoting exactly rather than paraphrasing: consumption of foods containing maltitol instead of sugar induces a lower blood glucose rise after their consumption compared to sugar-containing foods. That is a statement about the sweetener, not about any condition, and nothing here is medical advice.

Polyols and portions

Maltitol is a polyol, or sugar alcohol. Polyols are absorbed slowly, which is precisely why they are used. Packs above 10 percent polyols carry the note that excessive consumption may produce laxative effects, so two or three biscuits at a time is the sensible way in and your gut adjusts. Anyone managing a health condition should lean on their care team for personal advice.

Where Gullon sits

Gullon is a Spanish biscuit manufacturer with a long-running sugar free range, sweetened with polyols rather than sugar, in standard formats such as digestives and Maria biscuits. It sits in the same category as the Diablo biscuit range: familiar shapes with the sugar replaced. Check the claim on the front and the sweetener in the ingredients list, as with any pack.

How to read a sugar-free biscuit label

  1. Find the claim. Sugar free means no more than 0.5g of sugars per 100g. No added sugar means nothing sweetening was added, with naturally occurring sugars declared as they are.
  2. Name the sweetener. The ingredients list says which one, usually as "sweetener: maltitol". Where it sits in the list tells you how much of it there is.
  3. Read the carbohydrate line, not just the sugars line. Flour is the bulk of any biscuit, so carbohydrate stays substantial: 31g per 100g on our Almond Cookies, 67g on the Digestives.
  4. Work out your actual portion. The per 100g column is a comparison tool. Two or three biscuits is the real-world serving.
  5. Check the allergens. Most sugar free biscuits carry wheat, and many carry egg, milk or soya. Ours are listed in full on each pack.

What to put in the basket

For the lowest sugars figure, the three Sugar Free cookie lines measure 0.2g per 100g and the sandwich biscuits 0.4g. For the lowest carbohydrate, the NAS Almond Cookies 145g at 31g, then the SF Coconut Cookies at 35g. For a tea biscuit, the NAS Digestive at 5g fibre per 100g. One pack to start with: the SF Chocolate Chip Cookies, the closest thing in the range to the biscuit most people are replacing.

Frequently Asked Questions

What is the difference between sugar free and no added sugar on biscuit packaging?
Sugar free is the stricter claim: no more than 0.5g of sugars per 100g. No added sugar means no sugars were added during production, while sugars that occur naturally in ingredients such as milk and wheat remain and are declared on the panel. As a worked example: our SF Chocolate Chip Cookies 130g measure 0.2g of sugars per 100g, and our NAS Digestive Cookies 150g measure 1g.
Which Diablo biscuit has the lowest carbohydrate?
The NAS Almond Cookies 145g (COK-145-ALM-P12) at 31g per 100g, followed by the SF Coconut Cookies 150g at 35g. The sandwich biscuits and the digestives sit higher, at 66g and 67g per 100g, because of the flour content in those formats.
What sweetener is in Diablo biscuits?
Maltitol, listed on every pack as "sweetener: maltitol". The chocolate drops in the SF Chocolate Chip Cookies are sweetened with maltitol as well, which is how the whole biscuit stays under the sugar free threshold.
Are Diablo biscuits suitable for vegans?
No. The Cookies lines are made with pasteurised egg, and the sandwich biscuits contain milk. Full allergen information is printed on each pack and published on every product page.
Can you eat too many sugar-free biscuits?
Portion sense applies as with any biscuit. These are not low calorie foods: our SF Coconut Cookies carry 463 kcal per 100g. Packs above 10 percent polyols note that excessive consumption may produce laxative effects, so two or three at a time is the sensible way in and your gut adjusts.
