For a weekly shop, choose a biscuit explicitly labelled sugar free if that is the claim you need: ASDA lists Gullón Zero as “No Sugar” and Sainsbury’s lists Siro as “Sugar Free”, while Diablo is labelled no added sugar and McVitie’s The Light One is reduced sugar. Compare the carbohydrate information and pack size as well as the sugars line, then check allergens and polyol warnings before choosing a biscuit for the household cupboard.
If you want digestives for a regular tea-time or lunchbox cupboard, check for an explicit sugar-free claim rather than assuming that “reduced sugar” means the same thing. Pack size, allergens and the sweetener warning also matter when several people may eat from the same pack.
A sugar-free label does not mean carbohydrate-free. Compare total carbohydrate and the serving information on the pack; Diabetes UK advises people adjusting insulin doses to seek individual guidance from their healthcare team about polyols.
A 400g pack may suit a shared cupboard differently from a 150g specialist pack. Check the current unit price only after confirming that the product meets your preferred sugar claim and allergen requirements, and check how a Marketplace item will be delivered.
Start with the exact claim on the pack, then compare nutrition and ingredients among the biscuits that meet it. Pack size and fulfilment can help settle the weekly-shop choice.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar claim | Read the exact wording and sugars per 100g. ASDA describes Gullón Zero as “No Sugar” and Sainsbury’s describes Siro as “Sugar Free”; Tesco Marketplace calls Diablo “No Added Sugar”, while Tesco calls McVitie’s The Light One “Reduced Sugar”. | If I specifically want a sugar-free label, a reduced-sugar or no-added-sugar claim will not answer that requirement. |
| Nutrition | Compare total carbohydrate and energy per 100g, then check the per-biscuit serving information. The Gullón Zero listing states 68g carbohydrate and 430 kcal per 100g despite its no-sugar claim. | I want to know what a usual serving contributes, rather than choosing by the sugars line alone. |
| Sweeteners and allergens | Check the ingredients, allergen statement and any polyol warning. Gullón Zero lists isomalt and maltitol; the Siro listing identifies sweetener and polyols. Both sugar-free listings warn that excessive consumption may produce a laxative effect. | If the pack will be shared regularly, I need to check that its ingredients suit everyone who will eat it. |
| Pack and delivery | Compare pack size and the current price per kg among products that meet your requirements. The listed packs are Gullón Zero 400g, Siro 300g, Diablo 150g and McVitie’s The Light One 250g; check delivery arrangements for the Tesco Marketplace item. | A cupboard-sized pack matters to me, but I would not switch to a different sugar claim just for a larger pack. |
McVitie’s The Light One is labelled reduced sugar and still contains sugar. Diablo carries a no-added-sugar claim, which is different from the sugar-free wording on the Gullón Zero and Siro listings.
Decide which claim you need before shopping, then check the product description and nutrition panel rather than relying on a familiar brand name.
Gullón Zero’s listed nutrition includes 68g carbohydrate and 430 kcal per 100g. The sugar claim alone does not describe the biscuit’s full nutrition.
Compare carbohydrate, energy and serving information alongside sugars when deciding how the biscuits fit into your usual shop.
The Gullón Zero and Siro labels warn that excessive consumption may produce a laxative effect. Diabetes UK also notes that polyols contain carbohydrate and calories.
Read the sweetener ingredients and on-pack warning. If you adjust insulin doses for carbohydrate intake, seek individual advice from your healthcare team, as Diabetes UK recommends.
Diablo’s listed pack is 150g and is sold through Tesco Marketplace, rather than as a standard Tesco grocery-range item. Its delivery arrangements may therefore matter to a planned weekly shop.
First shortlist products with the claim and allergens you require; then compare pack sizes, current unit prices and checkout delivery details.
These labels describe the listed products, not every biscuit made by each brand or what a retailer currently has in stock.
ASDA lists Gullón Zero Digestive Original Biscuits as a 400g “No Sugar” option.
Sainsbury’s lists Siro Sugar Free Digestive Biscuits in a 300g pack.
Tesco Marketplace lists Diablo No Added Sugar Digestive Cookies in a 150g pack.
Tesco lists McVitie’s Digestives The Light One as a reduced-sugar wheatmeal biscuit, not a sugar-free one.
This 400g Gullón Zero option is relevant if an explicitly sugar-free digestive and a larger pack suit your weekly shop. Check the product label for the ingredients and nutrition that matter to your household.

The 400g pack suits a shop for a shared biscuit cupboard if you want an explicitly sugar-free label. The product information states under 0.5g sugars, 68g carbohydrate and 430 kcal per 100g. It contains wheat and uses isomalt and maltitol; check the allergen statement and the warning that excessive consumption may produce a laxative effect.
No. The listed Gullón Zero biscuits contain 68g carbohydrate and 430 kcal per 100g. Check total carbohydrate and the serving information as well as the sugars line.
A sugar-free label alone is not enough to plan that swap. Diabetes UK explains that polyols contain carbohydrate and advises people adjusting insulin doses to seek individual guidance from their healthcare team; check the biscuit’s total carbohydrate, polyols and serving size.
The Gullón Zero and Siro listings identify polyol sweeteners and warn that excessive consumption may produce a laxative effect. Read the ingredients and serving information when choosing a pack for regular household use.
No. The listed Gullón Zero and Siro sugar-free digestives contain wheat. If you need to avoid wheat or gluten, check the allergen declaration on the specific pack rather than relying on its sugar-free claim.
No. The Gullón Zero and Siro product listings state that “digestive” does not indicate digestive properties. Choose between them using the claim, ingredients and nutrition information relevant to your shop.
