Who is this choice for?

Shoppers who require sugar-free

Compare total sugars per 100 g rather than treating reduced-sugar or no-added-sugar wording as equivalent. Check the ingredients and the pack you receive as well.

Shoppers looking for less sugar

If a sugar-free claim is not essential, compare reduced-sugar, no-added-sugar and ordinary digestives using their sugars per 100 g, energy figures and the portion you plan to eat.

Shoppers checking sweeteners or allergens

Read the sweetener and allergen statements on the specific biscuit. The ASDA listing for Gullón Zero identifies wheat, possible milk and soya presence, and an excessive-consumption warning.

What should you check?

Start with the claim you need, then compare nutrition figures on the same per-100 g basis and read the pack for ingredients and serving information.

Priority What to check Your needs
Sugar-free claim The UK version of Regulation (EC) No 1924/2006 on legislation.gov.uk sets the limit at no more than 0.5 g sugars per 100 g for a food making this claim. ASDA lists Gullón Zero Digestive Original at less than 0.5 g per 100 g. I need a digestive that meets the sugar-free claim, not simply one labelled with less or no added sugar.
Other sugar labels Tesco lists McVitie’s The Light One at 8.9 g sugars per 100 g. Diablo’s manufacturer lists its no-added-sugar digestive at 1.7 g per 100 g; a retailer lists 1 g. Both Diablo figures exceed the sugar-free limit, so check the pack for the figure you use. If sugar-free is not essential, I can compare these alternatives without treating their different claims as interchangeable.
Carbohydrate and energy Compare total carbohydrate and energy as well as sugars. The checked Gullón Zero product lists 68 g carbohydrate and 430 kcal per 100 g. For a comparison affected by a medical requirement, follow your individual clinical advice. A low sugars figure alone does not tell me whether the rest of a biscuit’s nutrition information suits my requirements.
Ingredients and warnings Check sweeteners, allergen statements and any serving warning on the pack. The Gullón Zero listing names isomalt and maltitol, identifies wheat and possible milk or soya presence, and warns about excessive consumption. I want to know what is in the biscuit before choosing it, particularly if an ingredient or allergen matters to me.
Portion and pack Compare the amount you intend to eat with the serving and per-100 g figures. Read the delivered pack before eating, especially when an allergen or a particular nutrient figure matters. The portion I eat may differ from the serving shown on a listing, so I need figures I can apply to that portion.

Common buying mistakes

  • Reading “reduced sugar” as “sugar-free”

    Tesco lists McVitie’s The Light One at 8.9 g sugars per 100 g. Diablo’s manufacturer lists its no-added-sugar digestive at 1.7 g per 100 g. Neither figure falls within the 0.5 g per 100 g sugar-free claim limit stated in the UK version of Regulation (EC) No 1924/2006.

    If sugar-free is a requirement, use the total sugars figure per 100 g rather than the front-of-pack phrase alone.

  • Assuming sugar-free means an unrestricted portion

    The checked Gullón Zero biscuit still lists carbohydrate and energy, and its product warning says excessive consumption may produce a laxative effect.

    Check the serving information against the amount you intend to eat, and read the sweetener warning.

  • Relying on an online panel for the final detail

    Diablo’s manufacturer and a UK retailer give different nutrition figures for the 150 g no-added-sugar digestive. The difference matters if you need a particular figure to make your choice.

    Use the listing to narrow your options, then check the delivered pack before eating, particularly for allergens.

Brand and product-line references

These are references to specific digestive products or ranges, not claims about every biscuit each brand makes.

Gullón Zero

Gullón describes its Zero digestive as sugar-free and made with sweeteners.

  • ASDA lists Zero Digestive Original at less than 0.5 g sugars per 100 g.
  • The listed product contains wheat, may contain milk or soya, and carries an excessive-consumption warning.

McVitie’s

The Light One is a reduced-sugar digestive, not a sugar-free one.

  • McVitie’s describes it as having 30% less sugar than the average digestive biscuit; this is the brand’s comparison.
  • Tesco lists the 250 g product at 8.9 g sugars and 464 kcal per 100 g.

Diablo

Its 150 g digestive is described as no-added-sugar rather than sugar-free.

  • The manufacturer lists maltitol among its ingredients.
  • The manufacturer and Holland & Barrett list different nutrition figures; both listed sugars figures exceed 0.5 g per 100 g. Use the pack for a detailed comparison.

Tesco

Tesco’s own-brand 400 g digestive is an ordinary-biscuit comparison.

  • Tesco lists 14.6 g sugars per 100 g for this product.
  • Its ingredient list includes sugar and partially inverted sugar syrup; do not treat this product as sugar-free.

Sainsbury’s

Its own-brand 400 g digestive provides another ordinary-biscuit comparison.

  • Sainsbury’s lists 16.3 g sugars per 100 g for this product.
  • Check the specific pack, as the retailer notes that ingredients can change.

ASDA

ASDA’s own-brand digestive is distinct from the Gullón Zero product it lists.

  • ASDA lists 16 g sugars per 100 g for its own-brand 400 g digestive.
  • The sugar-free description of Gullón Zero does not apply to ASDA’s own-brand biscuit.

Crawford’s

The checked Crawford’s Digestives 400 g listing describes a conventional biscuit.

  • The Iceland Foods listing identifies wholemeal wheat flour among its ingredients.
  • It also lists sugar and partially inverted sugar syrup; check a specific product’s sugars figure if you require sugar-free.

M&S

M&S lists plain, milk-chocolate and dark-chocolate digestive styles.

  • The range offers different digestive styles to compare.
  • Check the chosen product’s sugars per 100 g rather than assuming a claim applies across the range.

Questions about sugar-free digestives

Does sugar-free mean a digestive has no carbohydrate or calories?

No. The checked Gullón Zero listing gives less than 0.5 g sugars alongside 68 g carbohydrate and 430 kcal per 100 g. If you manage carbohydrate intake for a medical reason, follow your individual clinical guidance and check total carbohydrate, not only sugars.

What should I check if I avoid wheat, milk or soya?

The checked Gullón Zero listing identifies wheat and says milk and soya may be present. Read the delivered pack’s ingredients and allergen statements before eating; sugar-free does not mean allergen-free.

What is the UK sugar-free claim limit for biscuits?

The UK version of Regulation (EC) No 1924/2006 on legislation.gov.uk states a limit of no more than 0.5 g sugars per 100 g for a food making a sugar-free claim. Compare that with the biscuit’s total sugars per 100 g; reduced-sugar and no-added-sugar wording describes different claims.

Do these digestives need preparation or special storage?

The checked biscuits are ready to eat. The Gullón listing says to keep them cool and dry, away from sunlight, and reseal after opening; follow the instructions on the pack you receive.
