Questions about peanuts

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

How many calories are in a portion of peanuts?

A typical portion (30 g, a small handful) gives 181 kcal. Per 100 g the figure is 602 kcal.

Is peanuts high in biotin?

Yes. Peanuts, roasted and salted have 0.102 mg biotin per 100 g, 204 % of the NRV, above the 30 % threshold for a “high in” claim.

Which vitamins and minerals do peanuts have most of?

By share of the daily reference intake: biotin (0.102 mg, 204 %), niacin (18.9 mg, 118 %) and manganese (1.9 mg, 95 %) per 100 g.

Are peanuts a good source of protein?

Peanuts, roasted and salted have 24.7 g protein per 100 g, 16 % 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 14-834, Peanuts, roasted and salted, 20 analysed samples, published by Public Health England under the Open Government Licence v3.0. Main data references: Reviewed 2013. LGC, Savoury snacks and nuts, 1989-1991; and industry data, 2013. 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, and where no illustration of the exact food exists the nearest one is shown (here: Peanuts). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
