Dietary mineral

chemical element required as an essential nutrient by organisms to perform functions necessary for life

A dietary mineral is a chemical element that a living thing needs to be part of what they eat, other from the four elements carbon, hydrogen, nitrogen, and oxygen which are already very common in living things.

One example of a dietary mineral is calcium, which humans and many other animals need to build strong bones and teeth, among other things. Iron is another mineral, which you can find in red meat or spinach. It is important for us to have iron as it creates red blood cells. Other common minerals include potassium and phosphorus.
