Every McVitie's biscuit sold in the UK broken down by biscuit and by pack, and checked against NHS daily reference intakes for children aged 4 to 17.
McVitie's is the largest biscuit brand in Britain and the Digestive is the country's most eaten biscuit. What makes the range worth examining is that most of it is built on a small number of base biscuits with different coatings applied — so products that sit side by side on the shelf can differ substantially in fat and sugar while sharing almost the same underlying recipe.
Biscuits are the point where the sugar-only view of nutrition stops being useful. Unlike confectionery, a biscuit carries a significant fat load alongside the sugar, and much of that is saturated fat from the vegetable oils used in the base and the chocolate in the coating. Saturated fat has its own daily reference intake, and for a child it is often the figure that a coated biscuit uses up fastest — not the sugar.
The plain base biscuits are wheat flour, vegetable oil, sugar and raising agents. Wholemeal content in the Digestive range contributes a small amount of fibre, and the oat-based lines contribute more, along with beta-glucan — a soluble fibre that flour-based biscuits do not provide.
The coating is what separates most of the range. Adding milk chocolate to a plain biscuit raises both the sugar and the saturated fat substantially, and a caramel or filled variant adds a further sugar layer on top of that. Two biscuits of the same size and base can differ by half again in calories depending on what is on the outside.
The plainer lines sit at the other end. A tea biscuit carries less sugar and less fat per biscuit than any coated product in the range, which makes it the useful reference point when comparing the rest.
Pack format drives real intake. Biscuits are eaten in twos and threes rather than singly, and multipacks, tubes and sharing packs differ several-fold in what a sitting actually amounts to. The per-biscuit figure is the starting point, not the answer.
Each product page includes a full nutrition breakdown per biscuit and per pack, portion size comparisons at 2, 4 and 6 biscuits and full pack, age-adjusted NHS daily reference intake calculations for children aged 4 to 17, an interactive calculator for your child's specific age and gender, and a complete ingredient and allergen guide.
