護理師為老年人舉辦營養課程。下列哪項建議最適合促進骨骼健康？
A nurse is conducting a nutrition class for older adults. Which recommendation is most appropriate for promoting bone health?
- ALimit vitamin D intake to avoid toxicity限制維生素 D 攝取以避免中毒
- BAvoid all dairy products to reduce fat intake避免所有乳製品以降低脂肪攝取
- CInclude weight-bearing exercises in daily routines✓ 正解在日常活動中加入負重運動
- DConsume at least 800 mg of calcium daily每日攝取至少 800 mg 鈣質
— Explanation · 中文詳解 —
促進骨骼健康的核心包含攝取足夠鈣質（成人需 1000-1200mg/day，選項 D 僅 800mg 太低）、充足維生素 D，以及負重運動（Weight-bearing exercises）。負重運動能刺激成骨細胞活性，防止骨質流失。乳製品是優質鈣來源，不應全數避免（B）。
Weight-bearing exercises are essential for maintaining bone density by stimulating osteoblast activity. While calcium and vitamin D are important, mechanical stress from exercise is a critical component of bone health promotion.
