Questions about chicken eggs
The questions people ask about chicken eggs, answered from the dataset.
How many calories are in a portion of chicken eggs?
A typical portion (60 g, one medium egg) gives 31 kcal. Per 100 g the figure is 52 kcal.
Is chicken eggs a source of niacin?
It is a source of niacin: 4.1 mg per 100 g, 26 % of the NRV, which passes the 15 % threshold for “source of” but not the 30 % needed for “high in”.
Does boiling change the folate in chicken eggs?
Yes. Per 100 g, folate goes from 10 mg raw to 0.004 mg boiled. Part of that is the vitamin or mineral itself changing, part is the change in water content.
Which vitamins and minerals do chicken eggs have most of?
By share of the daily reference intake: niacin (4.1 mg, 26 %), chloride (164 mg, 21 %) and vitamin B12 (0.0005 mg, 20 %) per 100 g.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 12-941, Eggs, chicken, white, boiled, 12 analysed samples, published by Public Health England under the Open Government Licence v3.0. Main data references: DH, Nutrient analysis of eggs, 2012. Values are per 100 g of the edible part; a egg is 60 g, one medium egg, the usual UK portion for eggs. 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 15 eggs 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: Egg). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
