If your priority is the lowest listed sugars figure among the digestives compared here, Sainsbury’s lists Siro Sugar Free Digestives at 0.5g sugars per 100g, but they contain maltitols and carry an excessive-consumption warning. McVitie’s The Light One is reduced sugar rather than sugar free, at 8.9g per 100g; Tesco’s standard digestives list 15.3g per 100g and do not meet a reduced-sugar aim. For a budget shop, decide which sugar figure and ingredients suit your shopping list before comparing pack sizes.
McVitie’s The Light One may suit you if you want a reduced-sugar digestive that still contains sugar. McVitie’s lists 8.9g sugars per 100g; Tesco lists 15.3g per 100g for its standard digestives.
Siro Sugar Free Digestives are worth comparing if you accept a sweetener-based recipe. Sainsbury’s lists 0.5g sugars and 13g polyols per 100g, alongside a warning about excessive consumption.
Check the current pack rather than relying on its sugar claim. Asda lists wheat and a may-contain-milk statement for McVitie’s The Light One; Tesco Marketplace lists wheat, milk and soya for Diablo No Added Sugar Digestive Cookies.
Start with the sugars figure and ingredient list, then check whether the biscuit is the style and pack size you want.
| Priority | What to check | When it matters to me |
|---|---|---|
| Listed sugars | Compare sugars per 100g across packs. Sainsbury’s lists Siro at 0.5g, McVitie’s lists The Light One at 8.9g, and Tesco lists its standard digestives at 15.3g per 100g. | I want to see the difference between sugar-free, reduced-sugar and standard digestives rather than choose by the front-of-pack wording. |
| Sweeteners | Read the ingredients and any consumption warning. Sainsbury’s lists maltitols and 13g polyols per 100g for Siro, with a warning that excessive consumption may produce laxative effects. | A lower sugars figure matters to me, but I also want to know whether the recipe uses sweeteners. |
| Allergens | Check the current pack’s contains and may-contain statements. Asda lists wheat and possible milk for McVitie’s The Light One; Tesco Marketplace lists wheat, milk and soya for Diablo. | Before putting a biscuit in my basket, I need its exact ingredient and allergen information. |
| Biscuit style and pack | Check whether the pack contains a digestive or another biscuit style, and compare pack weights. An oat-based biscuit should not be assumed to have the same recipe as a wheatmeal digestive. | I might welcome a different biscuit, or I might specifically want digestives for this shop. |
McVitie’s The Light One still lists sugar and partially inverted sugar syrup in its ingredients, with 8.9g sugars per 100g.
Compare the sugars-per-100g figures, then check the per-biscuit figure if that is how you plan to use the pack.
Sainsbury’s lists maltitols in Siro Sugar Free Digestives and warns that excessive consumption may produce laxative effects.
Read the ingredients and warning before choosing a sweetener-based biscuit; consider a reduced-sugar recipe instead if you want to avoid that ingredient.
A lower sugars figure does not establish whether a biscuit meets an allergen requirement. Asda lists wheat and possible milk for McVitie’s The Light One.
Check the contains and may-contain statements on the exact pack you intend to buy.
