nutrient
noun
Nutrient — the precise substance a body needs in order to thrive
Definition
Any substance that can be metabolized by an animal to give energy and build tissue
In depth
A nutrient is any substance that can be metabolized to provide energy or build tissue, the specific chemical components — vitamins, minerals, proteins — that make food more than mere bulk. Where 'food' names the broader cultural and physical act of eating, 'nutrient' isolates the precise biological mechanism beneath it.
Origin
The word derives from Latin nutrire, to nourish or suckle, the same root behind 'nurture' and 'nurse.' Its scientific specificity emerged largely in the nineteenth and twentieth centuries, as chemistry advanced enough to isolate the particular compounds within food responsible for sustaining the body, splitting the ancient concept of nourishment into its measurable parts.
Usage examples
"The soil had been depleted of the nutrients the crop most needed to thrive."
"Doctors warned that the diet, however filling, left her dangerously short of essential nutrients."
"The deep sea floor, lightless and cold, still teems with life sustained by nutrients drifting down from far above."
How to use it
Nutrient is a clinical, scientific term, most at home in biology, medicine, and agricultural writing. It rarely carries the cultural and emotional resonance of 'food,' and writers reaching for warmth or intimacy will usually prefer the plainer word.
