Revise: Dietary MineralsMinerals are inorganic nutrients that the body needs for normal growth and functioning. They are micronutrients: we need relatively small amounts, but that does not make them unimportant. Unlike fat, carbohydrate and protein, minerals do not provide energy.
Link a mineral to a specific function: iron is needed for haemoglobin, whereas calcium and phosphorus help build bones and teeth.
Keep units clear: iodine is measured in micrograms (µg), while most other mineral reference values are in milligrams (mg).
