Calcium is the most plentiful mineral in the body. Dairy foods, canned fish eaten with bones, tofu and green leafy vegetables are the main sources. This page sets out what may be said about calcium under the authorised UK wording and which foods carry the most of it per 100 g.
Calcium is the most plentiful mineral in the body. Dairy foods, canned fish eaten with bones, tofu and green leafy vegetables are the main sources.
The reference intake used on UK labels (the NRV) is 800 mg a day. A food is a source of calcium when 100 g carries at least 15 % of that (120 mg) and high in calcium at 30 % (240 mg). Those are the thresholds every food page here uses.
What Calcium does in the body.
Calcium is needed for the maintenance of normal bones and teeth, and contributes to normal muscle function.
Calcium is needed for the maintenance of normal bones and teeth, and contributes to normal muscle function.
That is the authorised wording, and it is credited to the nutrient itself. Nothing on this page goes beyond it.
How much counts as a source.
The Nutrient Reference Value for calcium on UK labels is 800 mg a day. A food counts as a source of calcium at 15 % of that per 100 g (120 mg) and as high in calcium at 30 % (240 mg); drinks use half those percentages per 100 ml. Those are the thresholds every food page here applies, and the only basis on which a food page says “source of” or “high in”.
