macronutrient
mak-roh-NOO-tree-unt
/ˌmæk.roʊˈnuː.tri.ənt/
A type of essential chemical nutrient required by the body in relatively large amounts, specifically carbohydrates, fats, and proteins.
Refers exclusively to energy-providing large components, in explicit contrast to micronutrients (vitamins and minerals).
The story behind the word. A modern scientific compound formed in the 20th century by combining Greek 'makros' (meaning 'large' or 'long') with Latin 'nutrire' (meaning 'to nourish'). It was coined to distinguish energy-dense bulk nutrients from micronutrients.
