Households stocking up on sugar-free biscuits
If several people will share the pack, compare its weight and approximate biscuit count as well as the sugar-free claim. A larger pack is useful only if its ingredients suit the people eating it.
Who is this for?
Shoppers considering polyol-sweetened biscuits
Gullón and Siro use sweeteners and carry excessive-consumption warnings. Check the ingredients and warning before buying several packs for a household that has not tried them.
Shoppers comparing sugars with total carbohydrate
Diabetes UK explains that polyols still provide carbohydrate and calories. If total carbohydrate matters to your choice, read that figure alongside sugars and polyols rather than relying on the front-of-pack claim alone.
What should you check?
Start with the claim you need, then compare pack size, sweeteners and allergens before deciding how many packs to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar claim | Read the exact claim and sugars per 100g. Asda lists Gullón Zero at less than 0.5g sugars per 100g; Sainsbury's lists Siro at 0.5g. Tesco calls Diablo no added sugar, while Waitrose calls McVitie's The Light One reduced sugar and lists 8.9g sugars per 100g. | I need an explicitly sugar-free biscuit, rather than one described only as no added sugar or reduced sugar. |
| Pack size | Compare pack weight and the stated biscuit or serving count on the same basis. Asda lists 400g and approximately 30 biscuits for Gullón; Sainsbury's lists 300g and approximately 23 servings for Siro. | For several people, I want enough biscuits without committing to more of an unfamiliar product than we will use. |
| Sweeteners | Check the ingredients, polyol figure where listed and on-pack warning. Sainsbury's lists 13g polyols per 100g for Siro; both Siro and Gullón carry excessive-consumption warnings. | Before stocking up, I want to know whether the household can use biscuits made with these sweeteners. |
| Allergens | Check the current pack for ingredients and precautionary allergen statements. Gullón and Siro contain wheat and may contain milk and soya; Tesco lists wheat, milk and soya in Diablo, with further may-contain statements. | Someone sharing the biscuits may need me to check more than the sugar claim. |
What could be overlooked?
-
Treating different sugar claims as interchangeable
A no-added-sugar or reduced-sugar label does not make a product the same choice as one labelled sugar free. Waitrose lists 8.9g sugars per 100g for McVitie's Digestives The Light One.
If sugar free is your requirement, check the exact claim and the sugars-per-100g figure rather than choosing by a similar-sounding name.
-
Buying several packs before checking the sweeteners
Gullón and Siro carry warnings about excessive consumption; Sainsbury's lists 13g polyols per 100g for Siro.
Read the warning and try a smaller purchase before stocking up for people who have not eaten these biscuits before.
-
Focusing on sugar and missing allergens
The listed Gullón and Siro biscuits contain wheat and may contain milk and soya. Tesco lists additional allergen statements for Diablo.
Check the current pack's ingredients and allergen information before sharing it, particularly if a household member needs to avoid an ingredient.

The 400g sugar-free pack is an option when several people will share the biscuits. Its listed sugars are below 0.5g per 100g. It contains wheat, may contain milk and soya, and uses isomalt and maltitol; check the excessive-consumption warning before stocking up.
Common questions
Does sugar free mean carbohydrate free?
No. Diabetes UK explains that polyols provide carbohydrate and calories. Read total carbohydrate and any listed polyols alongside sugars when comparing biscuits; a sugar-free claim alone does not describe the whole nutrition panel.
Is no added sugar the same as sugar free?
No. They are different claims. Tesco labels Diablo Digestive Cookies no added sugar, so check its nutrition panel and claim wording if you specifically need a biscuit labelled sugar free.
Why do these biscuits carry an excessive-consumption warning?
The listed Gullón and Siro biscuits contain polyol sweeteners and carry that warning. GOV.UK food-labelling guidance specifies a laxative-effect warning for foods containing more than 10% polyols; read the warning on the pack before buying a large quantity.
Are the Gullón and Siro sugar-free biscuits gluten-free?
No: the listed Gullón and Siro products contain wheat. Both may also contain milk and soya, so check the current pack's allergen information before serving them.
