take in · manage

1. Origins, structure, and basic meaning

• Structure: 摂 has 13 strokes and the on-reading せつ. 摂取 (せっしゅ) and 摂生 (せっせい) both use small っ.
• Basic usage: 摂取 concerns taking water or nutrients into the body; 摂生 concerns maintaining health through one's way of life.

2. Common pitfalls and similar expressions

• Intake amounts and a healthy regimen
  • 水分摂取量 means the amount of water taken in. 栄養を摂取する means taking in nutrients; notice whether 量 is added to the word.
  • 休養と摂生 presents rest alongside health management. The example of regular walking shows that 摂生 does not refer only to how much someone eats.
