Questions about potato crisps
Four questions chosen by the facts above, so every food answers differently.

By share of the daily reference intake: chloride (1200 mg, 150 %), potassium (1020 mg, 51 %) and niacin (6.6 mg, 41 %) per 100 g.
Are potato crisps high in fibre?
It is a source of fibre (5.9 g per 100 g, above the 3 g line) but not high in fibre, which needs 6 g.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 17-693, Potato crisps, low fat, 20 analysed samples, published by Public Health England under the Open Government Licence v3.0. Main data references: LGC, Survey of the nutritional composition of savoury snacks and nuts, 1993; and Fatty Acids Supplement, 1998 with selenium estimated from 'potato based snacks', 'Analysis of foods for Selenium' 1994. Values are per 100 g of the edible part; a serving is 30 g, a small bag or bar, the usual UK portion for sweets and snacks. 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 82 sweets and snacks 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: Potato). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
