UK: ˌdaɪəˈtetɪks | US: ˌdaɪəˈtetɪks
n. The science or study of diet and nutrition in relation to health and disease.
dietetics = diet<food intake> + etics<study of>
- diet (from Greek diaita "way of life, regimen") refers to habitual nourishment or controlled food intake.
- etics (derived from Greek -etikos, an adjectival suffix indicating "pertaining to" or "study of," later adapted into English as a noun suffix for disciplines).
Etymology Origin:
The word dietetics traces back to Greek diaitētikos ("pertaining to diet"), combining diaita (lifestyle/nutrition) with -ikos (a suffix for fields of study). It entered English via Latin dietetica and French diététique, evolving into a scientific discipline focused on dietary health. The morphemes reflect a logical progression from "way of life" to a systematic study of nutrition.
