Questions about peanut butter

Four questions chosen by the facts above, so every food answers differently.

How many calories are in a portion of peanut butter?

A typical portion (30 g, a small handful) gives 182 kcal. Per 100 g the figure is 607 kcal.

Is peanut butter high in biotin?

Yes. Peanut butter, smooth has 0.094 mg biotin per 100 g, 188 % of the NRV, above the 30 % threshold for a “high in” claim.

Which vitamins and minerals does peanut butter have most of?

By share of the daily reference intake: biotin (0.094 mg, 188 %), niacin (17.4 mg, 109 %) and manganese (1.7 mg, 85 %) per 100 g.

Is peanut butter a good source of protein?

Peanut butter, smooth has 22.8 g protein per 100 g, 15 % of the energy, which meets the UK threshold for “source of protein”.

How these numbers were made

Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 14-892, Peanut butter, smooth, 10 analysed samples, published by Public Health England under the Open Government Licence v3.0. Main data references: Reviewed 2013. MW4, 1978; and industry data, 2013. Fatty acids from Fatty Acid Supplement, 1998 (14-865). Values are per 100 g of the edible part; a handful is 30 g, a small handful, the usual UK portion for nuts and seeds. 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 38 nuts and seeds 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. Contains public sector information licensed under the Open Government Licence v3.0.
