Not providing nutrients or nourishment to the body.
Many artificial sweeteners are considered nonnutritive because they contain few or no calories.
Nonnutritive → It is formed from "non-" (meaning not) and "nutritive" (from Latin "nutritivus", meaning nourishing). The word "nonnutritive" means not nourishing or lacking nutritional value.
Think of 'non-' meaning not, and 'nutritive' relating to nourishment — so nonnutritive refers to something that does not provide nourishment.
