Dietary calcium refers to the amount of calcium that is present in foods and consumed through diet. Calcium is an essential mineral for human health, playing a crucial role in maintaining strong bones and teeth, as well as proper functioning of muscles and nerves.
The body cannot produce calcium on its own, so it must be obtained through the diet or supplements. Food sources that are rich in dietary calcium include dairy products such as milk, cheese, and yogurt; leafy green vegetables like spinach and kale; fish such as salmon and sardines; and some fortified foods like cereals and juices.
It is important to maintain an adequate intake of dietary calcium throughout life, particularly for individuals at higher risk of developing osteoporosis or those with a history of bone fractures. The recommended daily allowance (RDA) of dietary calcium varies by age and sex, but generally ranges from 1000 to 1200 mg per day for adults over the age of 19.
