Questions about white bread sandwich
Four questions chosen by the facts above, so every food answers differently.
How many calories are in a portion of white bread sandwich?
A typical portion (300 g, one serving) gives 516 kcal. Per 100 g the figure is 172 kcal.
Is white bread sandwich high in chloride?
Yes. Sandwich, white bread, chicken salad has 414 mg chloride per 100 g, 52 % of the NRV, above the 30 % threshold for a “high in” claim.
Are these figures exact for white bread sandwich?
No. They are calculated from a standard recipe in the UK Composition of Foods Integrated Dataset (CoFID, 2021). A different recipe, portion of sauce or cooking method will move them, so read them as a typical estimate.
Which vitamins and minerals does white bread sandwich have most of?
By share of the daily reference intake: chloride (414 mg, 52 %), niacin (5.5 mg, 34 %) and phosphorus (105 mg, 15 %) per 100 g.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 11-964, Sandwich, white bread, chicken salad, published by Public Health England under the Open Government Licence v3.0; this record is a calculated recipe estimate. Main data references: University of North London, 1997. Recalculated in 2013. Values are per 100 g of the edible part; a serving is 300 g, one serving, the usual UK portion for dishes. 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 603 dishes 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: White Bread). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
