'nutrient-changing' is a compound word formed from 'nutrient' and 'changing.' 'Nutrient' comes from Latin 'nutrientem,' meaning 'nourishing,' and 'changing' is the present participle of 'change,' from Old French 'changier.'

'nutrient' and 'changing' were combined in modern English to describe processes or agents that alter nutrients, resulting in the compound adjective 'nutrient-changing.'

Initially, the words referred separately to nourishment and alteration, but together they now specifically refer to the act or process of altering nutrients.
