Shoppers requiring a sugar-free claim
Check sugars per 100 g on the nutrition panel. A biscuit described as no-added-sugar or reduced-sugar does not, by that description alone, meet the sugar-free threshold.
Who needs which label checks?
Shoppers tracking carbohydrate
Read total carbohydrate and portion information alongside sugars. Diabetes UK notes that polyols contain carbohydrate and calories; anyone adjusting insulin should seek individual advice from their healthcare team.
Small top-up-shop buyers
Pack size and the type of listing matter for a quick purchase. Sainsbury’s lists Siro as a 300 g grocery product, while Tesco Marketplace lists Diablo as a 450 g three-pack supplied by courier.
What matters when choosing?
Decide whether sugar-free status is essential, then compare the full label and the pack format that fits your shop.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar-free status | The legislation.gov.uk annex sets the sugar-free claim threshold at no more than 0.5 g sugars per 100 g for a solid food. Sainsbury’s displays 0.5 g per 100 g for Siro; Tesco displays 8.9 g per 100 g for McVitie’s The Light One. | I need a biscuit that meets the sugar-free threshold, rather than one described only as no-added-sugar or reduced-sugar. |
| Carbohydrate and portions | Compare total carbohydrate, polyols and the portion you intend to eat. Sainsbury’s displays 73 g carbohydrate and 13 g polyols per 100 g for Siro. | For carbohydrate planning, I need more than the sugars figure. Diabetes UK notes that polyols contain carbohydrate and calories. |
| Sweeteners and allergens | Read the current ingredients, allergen statements and any polyol warning. Siro contains wheat, may contain milk and soya, and carries an excessive-consumption warning. | I want to check whether the ingredients and warning suit the person who will eat the biscuits before adding them to a repeat shop. |
| Pack and purchase format | Check pack size and whether the listing is for grocery shopping or a Marketplace delivery. Sainsbury’s lists a 300 g Siro pack; Tesco Marketplace describes Diablo as a courier-supplied 450 g three-pack. | A smaller grocery pack may fit my top-up shop better than a multipack, depending on how I plan to buy it. |
Mistakes to avoid
-
Treating “no added sugar” as “sugar-free”
These are different descriptions. Tesco lists Diablo as no-added-sugar, while McVitie’s The Light One has 8.9 g sugars per 100 g and is described as reduced-sugar.
If sugar-free status is essential, check both the claim and sugars per 100 g against the threshold stated in the legislation.gov.uk annex.
-
Looking only at the sugars figure
Sainsbury’s panel for sugar-free Siro also lists 73 g carbohydrate and 13 g polyols per 100 g. A low sugars figure is not a total-carbohydrate figure.
Read the carbohydrate and polyol entries for the portion you intend to eat. Diabetes UK advises people adjusting insulin to seek individual advice from their healthcare team.
-
Skipping the ingredients and warning
Siro contains wheat, may contain milk and soya, and carries a warning about excessive consumption. GOV.UK guidance specifies a laxative-effect warning for foods containing more than 10% polyols.
Check the current pack’s ingredients, allergen statements and warning, particularly when buying for someone else.
Brand and product-line references
These examples show why the wording on a digestive biscuit pack matters; a brand’s inclusion here does not mean every product it makes has the same label.
Siro
Sainsbury’s lists Siro Sugar Free Digestive Biscuits in a 300 g pack.
- Its displayed panel states 0.5 g sugars per 100 g.
- The panel also lists 73 g carbohydrate and 13 g polyols per 100 g; the product contains wheat and carries an excessive-consumption warning.
Gullón
Gullón describes its Digestive Zero wheat biscuit as sugar-free with sweeteners.
- The brand identifies isomalt and maltitol in its Digestive Zero ingredients.
- Check the nutrition panel and allergen statement on the particular pack you intend to buy.
Diablo
Tesco Marketplace lists Diablo No Added Sugar Digestive Cookies as a 450 g three-pack supplied by courier.
- The listing identifies maltitol as a sweetener and states 27.6% whole-wheat flour.
- A no-added-sugar description alone does not establish that the biscuits meet the sugar-free threshold.
McVitie’s
McVitie’s describes The Light One as having 30% less sugar than the average digestive biscuit, according to its statement on the Tesco listing.
- It is an option to consider when a reduced-sugar digestive, rather than a sugar-free one, meets your requirement.
- Tesco lists 8.9 g sugars per 100 g for The Light One.

Common questions
What does “sugar-free” mean on a digestive biscuit?
For a solid food, the sugar-free claim threshold stated in the legislation.gov.uk annex is no more than 0.5 g sugars per 100 g. Check the nutrition panel: “no added sugar” and “reduced sugar” are different descriptions.
Does a sugar-free digestive contain no carbohydrate?
No. Sainsbury’s displays 73 g carbohydrate and 13 g polyols per 100 g for Siro despite its 0.5 g sugars figure. Diabetes UK notes that polyols contain carbohydrate and calories and advises people adjusting insulin to seek individual advice from their healthcare team.
Why do some sugar-free biscuits carry a laxative-effect warning?
GOV.UK guidance specifies this warning for foods containing more than 10% polyols. Siro’s listing identifies maltitols and displays an excessive-consumption warning; read the warning on the pack you buy.
Does “digestive” mean the biscuit improves digestion?
No. Sainsbury’s Siro product information states that “digestive” does not mean the biscuit has specific digestive characteristics. Treat it as the name of a biscuit style, not a health effect.
What should I check for a quick top-up shop?
Check sugars per 100 g, total carbohydrate, ingredients, allergens and pack size, then confirm how the product can be bought in your area. A standard grocery listing and a courier-supplied Marketplace multipack may suit different shopping plans.
