Hosts comparing sugar figures
If you are putting out digestives to share, compare the labelled sugars per 100g and per biscuit rather than relying on a reduced-sugar claim alone.
Who is choosing?
Hosts serving guests with different dietary needs
Check the physical pack’s ingredients, allergen declaration and any consumption warning before offering either a reduced-sugar or a sweetener-based biscuit.
What should you compare?
Start with the per-100g label to compare biscuits, then use the serving information and ingredients on the pack you will put out.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Compare total sugars per 100g. Tesco lists 8.9g for plain McVitie’s The Light One and 15.3g for its standard digestive. The NHS guidepost for a food low in sugars is 5g or less per 100g. | I want to reduce sugars without assuming that a biscuit labelled “reduced sugar” is low in sugars. |
| Portions and energy | Check the current pack’s per-biscuit figures for the number you plan to serve. Tesco and Sainsbury’s both list 464kcal per 100g for plain The Light One, but give different energy figures per biscuit: 70kcal and 68kcal respectively. | For a sharing bowl, I want the serving figures to match the biscuits I actually put out. |
| Ingredients and warnings | Morrisons lists isomalt and maltitol in its 400g Gullón Zero digestive and warns that excessive consumption may produce a laxative effect. Check the physical pack’s allergen declaration for every guest. | A sugar-free option appeals to me, but I need to know what sweeteners it uses and whether guests can have its ingredients. |
| Flavour and pack size | Choose plain or cinnamon to suit the group. Tesco lists 8.9g sugars per 100g for both checked McVitie’s The Light One varieties; their packs are 250g, while the checked Gullón Zero pack is 400g. | I want a flavour guests will eat and a pack size that fits the number of people sharing. |
What is easy to overlook?
-
Reading “reduced sugar” as “low sugar” or “lower calorie”
Tesco lists plain McVitie’s The Light One at 8.9g sugars and 464kcal per 100g. Its manufacturer’s relative sugar claim does not describe either figure on its own.
Compare sugars and energy per 100g, then read the current pack’s per-biscuit values for the portion you will serve.

Overlooking the warning on a sugar-free biscuit
Morrisons lists isomalt and maltitol in its Gullón Zero digestive and warns that excessive consumption may produce a laxative effect.
Read the ingredients and warning on the supplied pack before setting out a shared portion.
-
Combining serving figures from different listings
Tesco and Sainsbury’s agree on the plain McVitie’s The Light One per-100g figures but list 70kcal and 68kcal per biscuit respectively.
Use the per-biscuit information on the pack being served rather than mixing figures from retailer listings.
Brand and retailer references
These figures describe the particular digestives named below, not every biscuit in each range.
McVitie’s
Its checked The Light One listings offer plain and cinnamon reduced-sugar digestives.
- Tesco lists 8.9g sugars per 100g for each checked variety.
- The plain pack’s “30% less sugar” comparison is the manufacturer’s claim against an average digestive. At 8.9g per 100g, it is above the NHS low-sugars guidepost of 5g or less per 100g.
Gullón Zero
The checked 400g digestive is a sugar-free, sweetener-based option rather than the same type of reduced-sugar claim.
- Morrisons lists isomalt and maltitol among its ingredients.
- The Morrisons listing warns that excessive consumption may produce a laxative effect. Compare pack energy figures before making a calorie comparison.
Tesco
Its checked standard digestive provides an own-label reference for a per-100g sugar comparison.
- Tesco lists 15.3g sugars per 100g for this standard digestive.
- That figure does not describe other Tesco biscuits or make the standard digestive a reduced-sugar option.
M&S
Its checked plain digestive is another specific standard-biscuit reference.
- M&S lists 18.2g sugars per 100g for the checked 400g pack.
- The checked biscuit is not presented as reduced sugar; check the label of any other variety separately.
Sainsbury’s
Its checked McVitie’s The Light One listing provides another label reference for the plain biscuit.
- Sainsbury’s lists 8.9g sugars and 464kcal per 100g for plain The Light One.
- Its 68kcal per-biscuit figure differs from Tesco’s 70kcal listing. Use the serving figure on the pack you have.

Gullon Zero Sugar Free Original Digestives 400g
This 400g sugar-free digestive is a sweetener-based alternative to a reduced-sugar biscuit for movie night. Morrisons lists isomalt and maltitol in the corresponding Gullón product and warns that excessive consumption may produce a laxative effect. Check the physical pack’s allergen declaration before serving guests.
Questions about choosing and serving
Does “30% less sugar” mean low in sugar?
No. McVitie’s compares plain The Light One with an average digestive, while Tesco lists 8.9g sugars per 100g for that biscuit. The NHS food-labelling guidepost for low sugars is 5g or less per 100g.
Is a sugar-free digestive lower in calories?
The sugar-free label alone does not establish a calorie comparison. Compare the energy figures per 100g on the current packs of the sugar-free and reduced-sugar biscuits you are considering.
What should I check before serving guests with allergies?
Read the physical pack’s ingredient and allergen information for each biscuit. The checked McVitie’s reduced-sugar digestive contains wheat, and Gullón’s information for its Zero digestive also lists wheat; a sugar claim does not tell you whether a biscuit suits a guest’s allergies.
Why does the sugar-free option carry a consumption warning?
The checked Morrisons listing for Gullón Zero names the sweeteners isomalt and maltitol and warns that excessive consumption may produce a laxative effect. Read the warning on the pack before putting out a large shared portion.
