Questions about green tea
What the numbers say to the questions people actually search.
How many calories are in green tea?
Almost none. The dataset records only a trace of energy per 100 g.
Which vitamins and minerals does green tea have most of?
By share of the daily reference intake: vitamin C (3 mg, 3.8 %), riboflavin (0.02 mg, 1.4 %) and potassium (20 mg, 1 %) per 100 g.
Is green tea high in salt?
No. Salt is 0 g per 100 g, which is very low under UK rules.
What counts as a portion of green tea?
This page uses 250 ml, a glass, the usual UK portion for drinks. Every “per portion” figure is the per-100 g value scaled to that weight.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 17-171, Tea, green, infusion, published by Public Health England under the Open Government Licence v3.0. Main data references: Reviewed 2013. Miscelleanous Foods Supplement, 1994. Values are per 100 g of the edible part; a glass is 250 g, a glass, the usual UK portion for drinks. 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 (per 100 ml thresholds for drinks). 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 61 drinks 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.
