Biscuit eaters looking to reduce sugar
If you want a digestive-style biscuit after dinner, the sugars figure per 100g gives you a clearer comparison than the word ‘Light’. The sweeteners and the portion you eat matter too.
Who is this choice for?
People deciding what to eat at bedtime
If timing matters more than having a biscuit, consider whether to have one at all. GOV.UK and Lancashire and South Cumbria NHS Foundation Trust advise avoiding sugar-containing foods and drinks at bedtime.
Shoppers checking ingredients closely
Check the exact pack if allergens or sweeteners affect your choice. Diablo lists wheat, milk-derived whey and soya, with possible sesame, nuts and mustard, and warns about excessive consumption of its maltitol-sweetened biscuits.
What should you check?
Compare sugars on the same per-100g basis, then consider the ingredients, portion and time you plan to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Declared sugars | Compare ‘of which sugars’ per 100g, then check the serving. Diablo reports 1.7g per 100g; M&S plain Digestive Biscuits list 18.2g, and Tesco lists 20.2g for McVitie's Light Digestives. | I want to reduce the sugar declared on the label, not choose a biscuit solely because it says ‘Light’. |
| Bedtime timing | Consider whether the snack contains sugar and how close it is to sleep. GOV.UK and Lancashire and South Cumbria NHS Foundation Trust advise avoiding sugar-containing foods and drinks at bedtime. | If I am eating immediately before bed, I may prefer a non-sugary option to a biscuit. |
| Sweeteners and portion | Read the ingredients and warning, as well as energy per 100g. Diablo lists maltitols, 17g polyols and 506 kcal per 100g, and warns that excessive consumption may produce a laxative effect. | A lower sugars figure does not settle how large a portion I want or whether its sweeteners suit me. |
| Allergens | Check the current pack's ingredients and ‘may contain’ statement for the exact variant. Diablo lists wheat, whey and soya, and may contain sesame, nuts and mustard. | I need the particular biscuit I buy to meet my ingredient requirements; a sugar claim cannot answer that. |
Common buying mistakes
-
Assuming ‘Light’ means less sugar
Tesco lists McVitie's Light Digestives at 20.2g sugars and 447 kcal per 100g. Its energy figure does not establish that it meets a reduced-sugar aim.
Compare ‘of which sugars’ per 100g first, then look at energy and your intended portion.
-
Treating ‘no added sugar’ as a reason to eat a larger portion
Diablo lists 506 kcal per 100g and warns that excessive consumption of its maltitol-sweetened biscuits may produce a laxative effect.
Check the nutrition panel and pack warning before deciding how many biscuits to have.
-
Assuming plain and chocolate digestives have the same sugar content
M&S lists 18.2g sugars per 100g for its plain Digestive Biscuits and 31.7g per 100g for its milk-chocolate version.
Compare the figures for the specific variants you are considering.
-
Overlooking when the biscuit will be eaten
GOV.UK and Lancashire and South Cumbria NHS Foundation Trust advise avoiding sugar-containing foods and drinks at bedtime, not merely exchanging one sugary biscuit for another.
If the snack is immediately before sleep, consider a non-sugary option instead.
Relevant brands and ranges
These brand references describe particular digestive products; they do not mean every range has a reduced-sugar version.
Diablo
Its No Added Sugar Digestive Cookies provide a digestive-style option for comparing declared sugars.
- Diablo lists 1.7g sugars per 100g.
- The biscuits use maltitols; Diablo lists 506 kcal per 100g and warns that excessive consumption may produce a laxative effect.
McVitie's
The Original is a wheat digestive; Light Digestives are a separate variant.
- McVitie's lists several pack sizes for The Original.
- Tesco lists Light Digestives at 20.2g sugars per 100g, so the name alone is not a reason to select them for less sugar.
Tesco
Tesco lists its own Digestives and a Diablo No Added Sugar product through Tesco Marketplace.
- The Diablo Marketplace listing identifies maltitols as sweeteners.
- Tesco says Marketplace orders are sent directly by the seller. Check the own-label pack's nutrition panel before comparing its sugars with another biscuit.
M&S
Its plain and milk-chocolate digestives provide two distinct variants to compare.
- M&S lists 18.2g sugars per 100g for its plain Digestive Biscuits.
- Its milk-chocolate digestives list 31.7g sugars per 100g; do not apply the plain biscuit's figure to that variant.
Asda
Asda lists standard Digestive Biscuits and a separate Free From digestive product.
- The standard Digestive Biscuits come in a 400g pack.
- The Free From product is labelled free from milk, but contains oats and may contain nuts; that label does not establish its sugar content.
Sainsbury's
Sainsbury's lists its own Digestives alongside McVitie's The Original.
- Its own-label Digestives are listed in a 400g pack.
- Read the current own-label nutrition panel before deciding whether its sugars figure fits your aim.
Crawford's
Crawford's Digestives are listed in a 400g retail pack and an 8 x 300g multipack.
- The two listed pack formats suit different quantities of biscuit buying.
- Sugar appears in the multipack ingredients; check the nutrition declaration before making a per-100g comparison.

Questions about late-night digestives
Does ‘no added sugar’ mean sugar-free or low in energy?
No. Diablo lists 1.7g sugars and 506 kcal per 100g for its No Added Sugar Digestive Cookies. Check the full nutrition panel and the portion rather than relying on the front-of-pack wording.
Does choosing a lower-sugar digestive settle the bedtime question?
No. GOV.UK and Lancashire and South Cumbria NHS Foundation Trust advise avoiding sugar-containing foods and drinks at bedtime. If you want a snack immediately before sleep rather than a biscuit specifically, consider a non-sugary option.
What should I check on a maltitol-sweetened biscuit?
Read its ingredients, nutrition panel and consumption warning. Diablo says excessive consumption of its maltitol-sweetened digestive-style cookies may produce a laxative effect.
How do I check whether a reduced-sugar digestive suits my allergen needs?
Read the current pack for the exact variant, including its ‘may contain’ statement. Diablo lists wheat, milk-derived whey and soya, and says its cookies may contain sesame, nuts and mustard.
