Etymology
The term "mineral" comes from the Latin word "mineralis," which means "something mined."
Types of Minerals
There are two types of minerals: Macrominerals and Trace minerals.
Macrominerals
Macrominerals are needed in larger amounts and include calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur.
Trace Minerals
Trace minerals, also known as microminerals, are required in smaller quantities and include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
Functions of Minerals
Minerals play a crucial role in various bodily functions. They are important for building strong bones and teeth, controlling body fluids, and turning the food we eat into energy.
Sources of Minerals
Minerals are found in a wide range of foods. The best sources are meat, cereals, fish, milk and dairy foods, vegetables, fruit (especially dried fruit), and nuts.
