Who needs to check the label?

Travellers avoiding sugars

Check for an explicit sugar-free claim on the exact biscuit. Wording such as “no added sugar” describes a different claim.

Travellers tracking carbohydrate

Compare total carbohydrate and the stated serving size, even when the front of the pack says sugar-free.

Travellers checking sweeteners or allergens

Read the ingredients and allergen information before the journey, particularly if polyols, wheat, milk, soya or nuts affect your choice.

What matters when choosing?

Start with the exact claim you need, then check the nutrition and ingredients information before deciding whether to pack the biscuit or look for it at the airport.

Priority What to check Your needs
Claim wording Read the exact sugar-free or no-added-sugar wording. Compare the sugars declaration per 100 g on the current pack. I want a biscuit labelled sugar-free, not one chosen because “no added sugar” sounds similar.
Carbohydrate and portion Check total carbohydrate per stated serving and how many servings the pack contains. Diabetes UK notes that the total amount of carbohydrate eaten matters for glucose levels after eating. If I track carbohydrate, the front-of-pack sugar claim alone will not tell me how this portion fits my usual plan.
Sweeteners and allergens Read the ingredients for polyols such as maltitol and check the allergen statement on the exact pack. Royal Berkshire NHS Foundation Trust advises that sugar alcohols can have a laxative effect in large quantities. I would rather choose a familiar biscuit than try an unfamiliar sweetener just before a flight.
Airport planning Check the airport’s shopping options for your flight if you intend to buy there. GOV.UK warns that food in hand luggage can require an additional manual security check. When the precise claim or ingredients matter, I want to check the pack before leaving instead of depending on a terminal shop.

What could catch you out?

  • Assuming “no added sugar” means sugar-free

    The two claims are distinct, so the wording on one biscuit cannot establish what another contains.

    If sugar-free is your requirement, look for that claim on the exact pack and read its nutrition declaration.

  • Stopping at the front-of-pack sugar claim

    A sugar-free label does not tell you the total carbohydrate in the portion you intend to eat.

    Compare total carbohydrate per serving and the number of servings in the pack. If you follow an individual carbohydrate or insulin plan, use your healthcare team’s guidance.

  • Trying an unfamiliar polyol-sweetened biscuit on travel day

    Royal Berkshire NHS Foundation Trust notes that sugar alcohols can have a laxative effect in large quantities, which may be inconvenient during a journey.

    Check the sweeteners in the ingredients list and consider a familiar snack if you know you are sensitive to polyols.

  • Depending on a purchase after security

    Heathrow shows reserve-and-collect products using flight details, so a biscuit seen in an airport range should not be assumed available for every journey.

    Check availability for your flight where a reservation service is offered, or pack a label-checked biscuit if your journey’s rules permit it.

Frequently asked questions

Does “no added sugar” mean sugar-free?

No. They are different nutrition claims. If you specifically need a sugar-free biscuit, check for that wording on the exact pack and read its sugars declaration rather than relying on a no-added-sugar name.

Is a sugar-free chocolate biscuit automatically suitable if I track carbohydrate?

No. Diabetes UK explains that the total carbohydrate eaten matters for glucose levels after eating. Check total carbohydrate for the portion you plan to eat and follow any individual guidance you have been given.

Can food in hand luggage need an extra security check?

Yes. GOV.UK says food can obstruct X-ray images and a bag may need a manual check. Check the airport and airline rules for your journey before packing biscuits.

Should I count on finding a sugar-free biscuit after security?

Not when the exact claim or ingredients are essential to your choice. Heathrow’s reserve-and-collect service uses flight details to show products for a journey; check the relevant airport’s options in advance or pack a biscuit whose label you have checked.

Why check for maltitol before travelling?

Maltitol is an ingredient Gullón lists for its Dark Choc Digestive Zero Sugar Free biscuit. Royal Berkshire NHS Foundation Trust notes that sugar alcohols can have a laxative effect in large quantities, so check the ingredients and consider your familiarity with the sweetener before choosing a travel snack.
