Families looking to cut back on biscuit sugar
Compare sugars per 100g and per biscuit before choosing a portion for a half-term snack. A reduced-sugar claim does not describe every aspect of the biscuit's nutrition.
Who is comparing these biscuits?
Families considering sugar-free biscuits
A sweetener-based digestive has a different recipe. Check its ingredients, carbohydrate figure and any consumption warning alongside its sugars figure.
Households checking food allergies
Read the wheat and precautionary allergen information on the particular pack before sharing biscuits. A sugar claim does not establish allergy suitability.
What matters when choosing?
Choose between a reduced-sugar recipe, a sweetener-based sugar-free recipe and an ordinary digestive by comparing the particular packs you would serve.
Reduced-sugar digestive
Consider it when: You want less labelled sugar than McVitie's Original without moving to a sugar-free recipe; its The Light One has 8.9g sugars per 100g versus 15.1g.
Bear in mind: The Light One still contains sugar, and McVitie's compares its 30%-less-sugar claim with an average digestive, not every other biscuit.
Sugar-free digestive with sweeteners
Consider it when: Minimising labelled sugars matters to you and a sweetener-based recipe suits the people eating it.
Bear in mind: Gullón Zero contains isomalt and maltitol; ASDA's listing warns that excessive consumption may have a laxative effect.
Ordinary digestive or another snack
Consider it when: You prefer a conventional digestive recipe, or decide that a biscuit is not what you want to serve.
Bear in mind: McVitie's Original lists 15.1g sugars per 100g; check other recipes individually rather than assuming they have the same figures.
| Priority | What to check | Your needs |
|---|---|---|
| Labelled sugar | Compare sugars per 100g and per biscuit. Check what a less-sugar claim uses as its comparator and the serving size on the pack. | I want to know how the sugar figure compares on the same weight basis, then how much is in the biscuit I might serve. |
| Other nutrition | Compare energy, saturated fat and salt per 100g. Where stated, check energy per biscuit against the portion you plan to offer. | Less sugar alone will not tell me what else changes between two biscuits. |
| Recipe and allergens | Read the sweetener list and any consumption warning. Check wheat and precautionary milk or soya statements on the specific pack. | I'd like to know whether the recipe uses sweeteners before sharing it, and I need the pack's allergen wording where allergies matter. |
What is easy to overlook?
-
Treating reduced sugar as a reason to ignore the portion
McVitie's lists 464kcal per 100g for The Light One. Its lower sugars figure does not, by itself, describe the energy in the amount served.
Start with per 100g figures for comparison, then use the nutrition information and biscuit size on the pack you receive.
-
Assuming sugar-free means the same recipe without sugar
Gullón Zero uses the sweeteners isomalt and maltitol. ASDA's listing also gives a carbohydrate figure and warns that excessive consumption may have a laxative effect.
Read the ingredients and warning before choosing this biscuit for a shared snack.
-
Applying school-food rules to snacks eaten at home
The Requirements for School Food Regulations 2014 restrict cakes and biscuits provided outside school lunch in the English school settings covered by those rules. They do not restrict biscuits eaten at home during half term.
Keep rules about food provided at school separate from your home-snack choice. Do not assume a digestive's HFSS classification from its name or sugar claim.
Brands and biscuit lines to compare
McVitie's
The Light One and Original provide two named digestive recipes to compare within the range.
- McVitie's lists 8.9g sugars per 100g for The Light One and 15.1g for Original.
- McVitie's 30%-less-sugar claim for The Light One uses the average digestive as its comparator; it does not describe every biscuit in the range.
Gullón
Zero Digestive is a sugar-free biscuit made with sweeteners, rather than a conventionally sweetened reduced-sugar recipe.
- Gullón lists isomalt and maltitol in the recipe; ASDA lists less than 0.5g sugars per 100g for its 400g Original product.
- ASDA's listing warns that excessive consumption may have a laxative effect. Check the particular pack's ingredients and allergen statements.
M&S
Its plain 400g Digestive Biscuits offer a named conventional-recipe comparison.
- M&S lists 18.2g sugars, 488kcal and 10.3g saturates per 100g for this product.
- Those figures apply to the named biscuit, not every M&S recipe. M&S advises checking the pack because product information can change.

Gullón Zero Sugar Free Original Digestives 400g
For a sweetener-based digestive, Gullón lists isomalt and maltitol in its Zero recipe. ASDA's listing for the 400g Original biscuits gives less than 0.5g sugars, 68g carbohydrate and 430kcal per 100g, and warns that excessive consumption may have a laxative effect. Check the pack's wheat and precautionary milk or soya information before sharing.
Common questions
Does 30% less sugar mean a digestive is low in sugar?
No. McVitie's says The Light One has 30% less sugar than the average digestive and lists 8.9g total sugars per 100g. NHS food-label guidance defines low sugar as 5g total sugars or less per 100g, so the two claims do not mean the same thing.
Can a biscuit's sugars figure tell me its free-sugars contribution?
Not exactly. The nutrition label states total sugars, while the NHS guidance on children's daily intake concerns free sugars. Do not treat the label's total-sugars figure as an identical measure.
How should I store The Light One after opening?
Tesco's listing for McVitie's The Light One says to keep it in a cool, dry place and use an airtight container once opened. Follow the instructions on the pack you buy.
Do English school-food rules apply to half-term biscuits eaten at home?
No. Food eaten at home is not food provided by a school. The Requirements for School Food Regulations 2014 restrict cakes and biscuits provided outside school lunch in the English school settings covered by those rules; they are not a UK-wide restriction on buying or eating digestives at home.
