Who is this choice for?

Tea-time gift buyers

If the recipient prefers less sugar, compare the figures on the nutrition panel rather than treating “reduced sugar” and “sugar-free” as the same claim. The choice also needs to suit what they can eat.

Regular digestive-biscuit buyers

McVitie’s The Light One and Gullón Zero offer different sugar figures, ingredients and allergen statements. Comparing each product per 100g makes those differences easier to see than comparing pack claims alone.

Anyone serving a person with allergen concerns

ASDA lists wheat and possible milk and soya for Gullón Zero; Ocado lists wheat and possible milk for McVitie’s The Light One. Check the actual pack before choosing or serving either biscuit.

What should you compare?

Start with sugars per 100g, then check energy, ingredients and allergens. A lower sugar figure answers only part of the gifting question.

Priority What to check Your needs
Sugars and labels Compare sugars per 100g on the same basis. ASDA lists Gullón Zero at less than 0.5g; Ocado lists McVitie’s The Light One at 8.9g and McVitie’s Original at 15.1g per 100g. I want to see how much sugar each biscuit declares, not rely on its front-of-pack wording. In a Food Standards Agency and Ipsos Northern Ireland survey of 611 adults interviewed from 16 September to 23 November 2024, 49% actively used traffic-light labelling when shopping for food; 40% of women checked nutrition information on the back of packs. Those figures describe food-shopping behaviour in Northern Ireland, not a preference for digestives.
Energy and serving Read energy alongside sugars: ASDA lists Gullón Zero at 430kcal per 100g, while Ocado lists The Light One at 464kcal per 100g. Check the pack’s serving information if you plan to put out a particular number of biscuits. A sugar-free label does not tell me how much energy is in a serving. I would compare the portion I expect to serve as well as the per-100g figures.
Ingredients and allergens Check the current ingredient list, allergen statement and any pack warning. Gullón Zero contains wheat, may contain milk and soya, and uses isomalt and maltitol; McVitie’s The Light One contains wheat and may contain milk. Before giving biscuits to someone with an allergen concern or a reason to avoid polyol sweeteners, I need to know whether the particular pack suits them. Gullón’s warning says excessive consumption may produce a laxative effect.

What is easy to overlook?

  • Reading sugar-free as calorie-free

    ASDA lists Gullón Zero at less than 0.5g sugars but 430kcal per 100g. The sugar claim does not replace the energy figure.

    Compare both figures per 100g, then check the serving information for the amount you intend to offer.

  • Overlooking the sweeteners and pack warning

    Gullón Zero contains isomalt and maltitol, and its pack warns that excessive consumption may produce a laxative effect.

    Read that warning when deciding whether the biscuit suits the recipient and how it will be served.

  • Confusing a sugar claim with allergen suitability

    Both Gullón Zero and McVitie’s The Light One contain wheat. ASDA also lists possible milk and soya for Gullón, while Ocado lists possible milk for The Light One.

    Check the current pack against the recipient’s allergen requirements; do not use a reduced-sugar claim as a substitute for its allergen statement.

  • Planning around the previous Mother’s Day

    UK Mothering Sunday in 2026 was 15 March. The calendar published by timeanddate.com lists 7 March 2027 as the next date.

    If this is a seasonal gift, check the occasion date before arranging when to give it.

Product and brand references

These are product-specific reference points, not conclusions about every biscuit made by each brand.

Gullón Zero

ASDA lists Gullón Zero Sugar Free Original Digestives 400g as wholemeal biscuits with sweeteners.

  • The listing gives less than 0.5g sugars, 6.5g fibre and 430kcal per 100g.
  • This product contains wheat, may contain milk and soya, and has a warning about excessive consumption of its sweeteners.

McVitie’s

Ocado describes Digestives The Light One as reduced-sugar wheatmeal biscuits and also lists the standard McVitie’s Original digestive.

  • The Light One lists 464kcal per 100g, contains wheat and may contain milk. It is not sugar-free.

M&S

M&S Digestive Biscuits offer a conventional product to compare with the sugar-free and reduced-sugar options, rather than a reduced-sugar claim.

  • Marks & Spencer lists wholemeal wheat flour and demerara sugar among this product’s ingredients.
  • Its listing gives 18.2g sugars and 488kcal per 100g; these figures apply to this product, not the whole M&S range.

Questions about reduced-sugar digestives

Does sugar-free mean a digestive is calorie-free?

No. ASDA lists Gullón Zero Sugar Free Original Digestives at less than 0.5g sugars but 430kcal per 100g. Read the energy figure and serving information as well as the sugar claim.

Can someone avoiding wheat choose either of these biscuits?

Neither Gullón Zero nor McVitie’s The Light One is a wheat-free choice: ASDA and Ocado respectively list wheat in these products. Check the current label for a biscuit that meets the recipient’s requirements rather than relying on a reduced-sugar claim.

Why does Gullón Zero carry a warning about excessive consumption?

ASDA lists the sweeteners isomalt and maltitol and says the pack warns that excessive consumption may produce a laxative effect. Read that warning when deciding whether to give or serve this product.
