Questions about pepper
Four questions chosen by the facts above, so every food answers differently.
How many calories are in a portion of pepper?
A typical portion (80 g, one of your five a day) gives 21 kcal. Per 100 g the figure is 26 kcal.
Is pepper high in vitamin C?
Yes. Pepper, capsicum, yellow, boiled in unsalted water has 77 mg vitamin C per 100 g, 96 % of the NRV, above the 30 % threshold for a “high in” claim.
Does boiling change the fat in pepper?
Yes. Per 100 g, fat goes from 0.2 g raw to 0.3 g boiled. Part of that is the vitamin or mineral itself changing, part is the change in water content.
Which vitamins and minerals does pepper have most of?
By share of the daily reference intake: vitamin C (77 mg, 96 %), potassium (218 mg, 11 %) and folate (0.021 mg, 11 %) per 100 g.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 13-537, Pepper, capsicum, yellow, boiled in unsalted water, published by Public Health England under the Open Government Licence v3.0. Main data references: DH, Nutrient analysis of fruit and vegetables, 2013. 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. 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. The dataset's sample note is not shown on the page (its wording trips the site's checks). 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: Yellow Bell Pepper). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
