What should you check?
Start with the requirement that matters for the child—sugar-free, gluten-free or neither—then check the particular pack for ingredients and warnings.
| Priority | What to check | Your needs |
| Sugar-free claim |
Check both the claim and sugars per 100 g. Legislation.gov.uk sets the sugar-free claim limit at no more than 0.5 g of sugars per 100 g of food; Asda lists Gullón Zero Original below 0.5 g and Sainsbury's lists Siro at 0.5 g per 100 g. |
I want a digestive that meets the sugar-free condition, rather than choosing one because it is labelled gluten-free or described as wholemeal. |
| Sweeteners |
Read the ingredients and any consumption warning. Asda lists isomalt and maltitol in Gullón Zero Original, while Sainsbury's lists maltitols in Siro; both carry an excessive-consumption laxative-effect warning. |
If I am choosing a sweetener-containing biscuit for a child, I want to check the pack's serving information and warning. |
| Wheat and other allergens |
Check the current pack's ingredients and precautionary statements. The Gullón Zero and Siro sugar-free digestives contain wheat and may contain milk and soya; the free-from alternatives have different declarations. |
Where gluten or another ingredient must be avoided, I need a product whose own declaration fits that requirement—not just a sugar-free label. |
| Where it will be eaten |
For a snack taken onto school premises, check that school's policy. Department for Education guidance covers food and drink provided in state-funded schools in England, not every parent-provided snack eaten after school. |
I may pack the biscuit for a school-run setting, so the school's rules matter alongside the information on the pack. |

Questions about after-school digestives
Does sugar-free mean a digestive contains no sugars at all?
No. Under the sugar-free nutrition-claim condition published by legislation.gov.uk, a food may carry that claim with no more than 0.5 g sugars per 100 g. Check the nutrition panel: Asda lists Gullón Zero Original below 0.5 g and Sainsbury's lists Siro at 0.5 g sugars per 100 g.
Are sugar-free digestives also gluten-free?
Not necessarily: the listed Siro and Gullón Zero sugar-free digestives contain wheat. If a gluten-free digestive is needed, check that declaration separately, then check sugars too; Sainsbury's and Asda list 19.7 g and 20 g sugars per 100 g respectively for their Free From Digestives.
Why do some sugar-free digestives carry a consumption warning?
The listed Siro and Gullón Zero products use polyol sweeteners and warn that excessive consumption may produce a laxative effect. Read the warning and serving information on the particular pack before choosing it for a child's snack.
Do school-food rules cover every after-school biscuit?
No blanket conclusion about every after-school snack follows from England's school-food guidance. The Department for Education says that guidance concerns food and drink provided in state-funded schools in England. For a biscuit brought onto school premises, check the individual school's food and allergen policy.
