How these numbers were made

Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 13-463, Sweet potato, raw, flesh only, published by Public Health England under the Open Government Licence v3.0. Main data references: Reviewed 2013. IFR, The nutritional compostion of retail vegetables in the UK, 1984-1987; and LGC, Fruit and vegetables, 1989-1990. Vitamin E estimated from USDA 99. Values are per 100 g of the edible part; a portion is 80 g, one of your five a day, the usual UK portion for vegetables. Edible proportion: 84 % of the weight as bought is eaten. 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 240 vegetables 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. Checked 5 October 2026.
