metabolism, renewal
The process by which the body converts food into energy and replaces old cells with new ones. Also used figuratively for the renewal or turnover of people or ideas in an organization.

Exercise boosts your metabolism.
年齢とともに新陳代謝が落ちてくる。
Metabolism slows down with age.
新陳代謝を良くするために、毎朝水を飲むようにしている。

USAGE:
新陳代謝 literally means "new replaces old" (新陳 = new and old, 代謝 = replacement/exchange). It is most commonly used in health and fitness contexts but can also describe organizational renewal.
COMMON COLLOCATIONS:
- 新陳代謝が良い (have a good metabolism)
- 新陳代謝を上げる (boost metabolism)
- 新陳代謝が落ちる (metabolism drops)
SHORTENED FORM:
In medical or scientific contexts, 代謝 alone is often used (e.g., 基礎代謝 = basal metabolism).
