護理師向青少年團體衛教營養需求。關於鐵質攝取，下列何者最為合適？
A nurse is teaching a group of adolescents about nutritional needs. Which information regarding iron intake is most appropriate?
- AAvoid drinking milk to prevent calcium-iron interaction避免飲用牛奶以防止鈣質與鐵質產生交互作用
- BTake iron supplements daily regardless of dietary intake無論飲食攝取量為何，每日服用鐵劑補充品
- CConsume iron-rich foods with vitamin C to enhance absorption✓ 正解攝取富含鐵質的食物並搭配維生素C以促進吸收
- DLimit intake of red meat as it inhibits iron absorption限制紅肉攝取，因為它會抑制鐵質吸收
— Explanation · 中文詳解 —
青少年時期因快速成長，對鐵質需求增加。鐵質分為血基質鐵（heme iron，動物來源）與非血基質鐵（non-heme iron，植物來源）。維生素C（Vitamin C）可將非血基質鐵還原為更易吸收的亞鐵離子，提升吸收率。臨床衛教應強調飲食搭配，而非依賴補充劑，以避免過量或不必要的副作用。優先考慮天然食物來源能建立長期的健康飲食習慣。
Adolescents have increased iron requirements due to rapid growth, making dietary education crucial. Vitamin C enhances the absorption of non-heme iron by creating an acidic environment that facilitates uptake, making this the most appropriate teaching point. Relying on supplements without diagnosis or avoiding essential nutrients like calcium is not recommended.
✦ 台美臨床差異
美國臨床更傾向於透過「MyPlate」指引進行營養衛教，強調食物多樣性與天然來源，避免過早建議藥物補充劑。
