Gamers comparing sugar on everyday snacks
If you plan to keep digestives on hand for gaming sessions, compare the sugars per 100g and per biscuit. That makes it easier to judge a pack against the portion you are likely to eat.
Who is this for?
Shoppers considering sugar-free biscuits
A sugar-free digestive may use sweeteners. Read the ingredients and any consumption warning alongside the nutrition table before choosing it for a longer session.
Parents and school-food buyers
A personal snack purchase is different from food supplied at school. The Department for Education’s school-food guidance and the Department of Health and Social Care’s retail-promotion guidance address different settings in England; check the rules relevant to the school and its menu.
What to check before buying
Start with a like-for-like nutrition comparison, then consider your portion and whether a sweetener-based recipe suits you.
| Priority | What to check | Your needs |
|---|---|---|
| Reading the sugar figures | Compare sugars per 100g, not just the claim on the front. Sainsbury’s lists 0.5g for Siro Sugar Free; Tesco lists 8.9g for McVitie’s The Light One and 14.6g for Tesco Digestives. | I want to read the nutrition label before choosing. In the Food Standards Agency and Ipsos Northern Ireland’s 2024 survey, 49% of the 611 Northern Ireland adults interviewed between 16 September and 23 November said they actively used traffic-light labelling when shopping for food; that figure does not describe gaming-snack buyers specifically. |
| Portion size | Check sugars per biscuit or serving as well as per 100g, then count the biscuits you expect to eat. Tesco lists 1.3g sugars per biscuit for McVitie’s The Light One and 2.0g for Tesco Digestives. | During a longer session, I may eat more than one biscuit, so the pack’s serving figure needs to match my likely portion. |
| Sweeteners and claims | Read the ingredients and warnings on sugar-free or no-added-sugar packs. Sainsbury’s displays an excessive-consumption warning for Siro; Tesco Marketplace lists maltitols in Diablo No Added Sugar Digestive Cookies. | I would rather check what gives a biscuit its sweetness than assume that “sugar free”, “no added sugar” and “reduced sugar” mean the same thing. |
Common buying mistakes
-
Treating “reduced sugar” as “sugar free”
Tesco lists McVitie’s The Light One at 8.9g sugars per 100g, while Sainsbury’s lists Siro Sugar Free at 0.5g per 100g. They are different claims with different declared figures.
Compare the exact pack’s nutrition table, then decide whether you want a reduced-sugar wheatmeal biscuit or a sugar-free recipe.
-
Overlooking a sweetener warning
Sainsbury’s listing for Siro Sugar Free warns that excessive consumption may produce laxative effects. The warning matters if you expect to eat several biscuits during a session.
Read the ingredient list and pack warning before deciding on your portion.
-
Using sugar alone to judge energy
A lower sugars figure does not, by itself, tell you how the products’ energy values compare.
If energy matters to your choice, check kcal per 100g and for the portion you intend to eat alongside the sugars figures.
-
Confusing retail-promotion rules with school-food checks
The Department of Health and Social Care’s HFSS retail-promotion guidance concerns promotion and placement in England. The Department for Education provides separate school-food guidance for England.
For food supplied at school, ask the catering provider to check the applicable nation’s requirements and the proposed product in the context of its menu. A reduced-sugar claim cannot settle that question.
Brand references
McVitie’s
The Light One is a reduced-sugar wheatmeal digestive listed by Tesco.
- Tesco lists 8.9g sugars per 100g and 1.3g per biscuit. Its listing gives the manufacturer’s claim of 30% less sugar than the average digestive biscuit.
- It is not sugar free and contains wheat.
Siro
Its Sugar Free Digestive Biscuits are listed by Sainsbury’s.
- The Sainsbury’s nutrition table lists 0.5g sugars per 100g.
- The listing identifies a sweetener and warns that excessive consumption may produce laxative effects.
Diablo

Questions about reduced-sugar digestives
Does “reduced sugar” mean a digestive is sugar free?
No. Tesco lists McVitie’s The Light One as reduced sugar, with 8.9g sugars per 100g; Sainsbury’s lists Siro Sugar Free separately, with 0.5g per 100g. Check both the wording and the nutrition table on the pack you buy.
Is a sugar-free digestive automatically the right gaming snack?
No. Sainsbury’s lists a lower sugars figure for Siro Sugar Free than Tesco lists for McVitie’s The Light One, but the Siro listing also carries an excessive-consumption warning. Consider the sweeteners, warning and your intended portion as well as sugars.
What should I compare on the pack?
Compare sugars per 100g and per biscuit or serving, then check energy for your intended portion, ingredients, allergens and any sweetener warning. Read the physical pack before eating, particularly when checking allergens.
Does “digestive” promise a digestive-health benefit?
No. “Digestive” identifies the biscuit type; the name alone does not establish a digestive-health effect. Choose using the ingredients and nutrition information relevant to your purchase.
