micronutrient
/ˌmaɪkroʊˈnuːtriənt/
Definition
An essential dietary element, such as a vitamin or mineral, required by the body in small quantities for health and physiological function.
Etymology
The word is formed by combining the Greek prefix 'mikros' (meaning 'small') with the English 'nutrient.' It was coined in the 20th century to distinguish these vital, trace-level dietary requirements from energy-providing macronutrients.
In the news
