Questions about biscuits
The questions people ask about biscuits, answered from the dataset.
How many calories are in a portion of biscuits?
A typical portion (30 g, two biscuits) gives 124 kcal. Per 100 g the figure is 413 kcal.
Is biscuits a source of copper?
It is a source of copper: 0.26 mg per 100 g, 26 % of the NRV, which passes the 15 % threshold for “source of” but not the 30 % needed for “high in”.
Which vitamins and minerals do biscuits have most of?
By share of the daily reference intake: copper (0.26 mg, 26 %), manganese (0.36 mg, 18 %) and chloride (121 mg, 15 %) per 100 g.
What counts as a portion of biscuits?
This page uses 30 g, two biscuits, the usual UK portion for cakes, biscuits and pastries. Every “per portion” figure is the per-100 g value scaled to that weight.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 11-811, Biscuits, fully coated with chocolate, with marshmallow, 10 analysed samples, published by Public Health England under the Open Government Licence v3.0. Main data references: DH, Nutrient analysis of biscuits, buns, cakes and pastries, 2011. Values are per 100 g of the edible part; a serving is 30 g, two biscuits, the usual UK portion for cakes, biscuits and pastries. Reference intakes follow Regulation (EU) 1169/2011 Annex XIII as retained in GB law; “source of”, “high in” and “low” follow Regulation (EC) 1924/2006, assessed per 100 g. Function lines are the authorised wording from the GB register of nutrition and health claims, credited to the nutrient. Energy is rounded to the whole kcal and kJ; other amounts to one decimal, or two below 1. A trace is shown as “trace” and never gets a figure or a badge; a nutrient never analysed is left off the page. We start from the dataset’s 2,887 records and keep 2,322: records weighed with bone, shell or skin, alcoholic drinks, infant foods, brand-named products, records with fewer than eight measured vitamins and minerals and near-identical variants are left out. Group context uses the 134 cakes, biscuits and pastries kept from the dataset; a rank counts only the foods with a measured figure for that nutrient. Food images are illustrations from Ingredient Atlas, released under CC0; they show the food, not the measured sample, and where no illustration of the exact food exists the nearest one is shown (here: Dark Chocolate). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
