Choose a sugar-free digestive only if its ingredients and precautionary allergen wording are suitable for the person who will eat it. Sugar-free examples listed by Sainsbury's and ASDA contain wheat and may contain milk and soya; free-from examples listed by Tesco and ASDA address different allergen requirements but contain sugar. Neither label replaces checking the exact pack.
The useful starting point is the intended eater's specific allergen requirement, not the biscuit's dietary category alone.
If wheat is suitable for the intended eater, compare sugar-free digestives against any other relevant allergen warnings. The Siro and Gullón examples listed by Sainsbury's and ASDA contain wheat and may contain milk and soya.
Look for a claim covering the particular allergen. Tesco lists its Free From Digestives as gluten, wheat and milk free, but also states that they may contain peanuts and nuts.
Check the ingredients and any 'may contain' wording on the exact pack against that person's requirements. The Food Standards Agency describes precautionary allergen labelling as information about allergens that could be unintentionally present.
Decide which allergen must be avoided first. Then compare the sugar claim and sugars per 100g among biscuits that meet that requirement.
Consider when: Sugar content is the main requirement and wheat is suitable for the intended eater.
Trade-off: The Siro and Gullón examples contain wheat and may contain milk and soya, according to their retailer listings.
Consider when: A biscuit must be labelled free from a named allergen such as gluten, wheat or milk.
Trade-off: The Tesco and ASDA examples contain sugar and carry nut-related precautionary wording, so check both requirements on the chosen pack.
| Priority | What to check | Your needs |
|---|---|---|
| Named allergens | Read the ingredients and highlighted allergens on the exact pack. Check that any free-from claim names the allergen you need to avoid. | I'm buying for someone who must avoid a particular allergen; a sugar-free claim alone cannot answer that question. |
| Cross-contact wording | Read every 'may contain' statement, including for milk, soya, peanuts and nuts. Assess it against the intended eater's allergy-management advice. | The ingredient may be absent, but I still need to know whether the pack carries a relevant precautionary warning. |
| Sugar content | Compare the precise claim with sugars per 100g on the nutrition panel. Tesco Groceries lists 24.8g per 100g for Tesco Free From Digestives; ASDA Groceries lists 20g per 100g for Free From by Asda Digestive Biscuits. | If I need a sugar-free biscuit as well as one suitable for an allergy, I cannot assume a free-from label covers both requirements. |
| Sweeteners and portions | Check the ingredients for sweeteners and follow any portion or excessive-consumption warning on the pack. | I want to understand what replaces sugar in the biscuit and any pack guidance before choosing a portion. |
| Current pack | Check the pack being purchased, even if you have bought a similarly named biscuit before. Match its variant and pack size to the information you compared. | When I'm buying for another person, I need the allergen and nutrition details for the biscuit they will actually receive. |
The Siro and Gullón sugar-free examples listed by Sainsbury's and ASDA contain wheat and may contain milk and soya.
Identify the allergen that matters first, then read the exact pack's ingredients and precautionary wording before comparing sugar content.
Tesco Groceries lists 24.8g sugars per 100g for Tesco Free From Digestives, while ASDA Groceries lists 20g per 100g for Free From by Asda Digestive Biscuits.
Check which allergens the claim covers and compare sugars per 100g separately if sugar content is also important.
A precautionary statement concerns possible cross-contact, even when the named allergen is not listed as an ingredient.
Read the whole allergen declaration and use the intended eater's allergy-management advice when assessing a warning.
The sugar-free Siro and Gullón examples contain sweeteners, and their retailer information warns about excessive consumption.
Check the sweeteners and any portion guidance on the pack rather than treating 'sugar-free' as a reason to ignore serving size.
These examples illustrate different label claims; a brand name alone does not establish whether a particular pack meets an allergy requirement.
The 400g Original Digestives listed by ASDA Groceries are a sugar-free example for shoppers who can consume wheat.
Siro Sugar Free Digestive Biscuits are another sugar-free route, rather than an all-allergen-free biscuit.
Tesco Free From Digestives are labelled gluten, wheat and milk free.
ASDA's digestive-biscuit listing identifies a milk-free product containing oats.
The Light One is a reduced-sugar digestive line, not a sugar-free or wheat-free substitute.
This sugar-free digestive option is relevant when sugar content is the starting point. For allergy shopping, check the allergen information on the pack before deciding whether it suits the intended eater.

A 400g sugar-free digestive option for shoppers comparing sugar claims. Its product information identifies wheat and a 'may contain' warning for milk and soya; check those details on the pack against the intended eater's requirements. It also identifies sweeteners and warns about excessive consumption.
No. A sugar claim does not describe allergen suitability. The Siro and Gullón sugar-free examples listed by Sainsbury's and ASDA contain wheat and may contain milk and soya; check the exact pack against the person's specific requirements.
Read the exact claim and compare sugars per 100g on the nutrition panel. McVitie's The Light One is marketed as a reduced-sugar biscuit, but Tesco Groceries lists 8.9g sugars per 100g; do not treat that wording as sugar-free.
Not necessarily. Tesco Groceries lists 24.8g sugars per 100g for Tesco Free From Digestives, and ASDA Groceries lists 20g per 100g for Free From by Asda Digestive Biscuits. Check both the relevant allergen claim and the nutrition panel.
The pack is the information for the biscuit being purchased. Recheck its ingredients, allergen declarations, 'may contain' wording and sugars per 100g, making sure you have the same product and variant you intended to buy.
Yes, if you need to assess ingredients or portion guidance. The Siro and Gullón sugar-free examples contain sweeteners and carry warnings about excessive consumption; read the wording on the chosen pack.
