Which substances are referred to as minerals in nutrition?

Minerals in nutrition are defined as elements used by the body. These inorganic substances are essential for various physiological functions, including building strong bones, making hormones, and regulating heartbeat. The body requires these minerals in small amounts to maintain health, as they contribute to many structural and functional roles. Examples of essential minerals include calcium, potassium, magnesium, and iron. Unlike organic compounds, which contain carbon and are typically derived from living organisms, minerals do not undergo metabolic processes in the same way; they retain their elemental form and provide crucial support for bodily functions. This distinction emphasizes why the answer identifying minerals as elements is the correct one, aligning with the established nutritional classifications.
