護理師正在提供關於一生中維持骨骼健康的教育。對年輕成人（18-30 歲）而言，哪項建議最重要？
A nurse is providing education on maintaining bone health throughout the lifespan. Which advice is most important for young adults (18-30 years)?
- AStart taking osteoporosis medication開始服用抗骨質疏鬆藥物
- BAvoid all physical activity避免所有體力活動
- CReduce protein intake減少蛋白質攝取
- DIncrease calcium intake to build peak bone mass✓ 正解增加鈣質攝取以建立峰值骨量
— Explanation · 中文詳解 —
骨峰值（Peak bone mass）通常在 30 歲左右達到頂峰。年輕成人階段（18-30 歲）是建立骨骼儲備的黃金時期，透過攝取足夠的鈣質、維生素 D 以及進行負重運動（Weight-bearing exercise），可以最大化骨骼密度。這段時期累積的骨本直接決定了老年後發生骨質疏鬆（Osteoporosis）的風險。這是預防醫學的核心，因為一旦超過這個年齡，骨骼密度便難以顯著增加，只能維持。
Young adults aged 18 to 30 are in the critical window for achieving peak bone mass, which directly influences their risk of osteoporosis later in life. Increasing calcium intake during this period maximizes bone density accumulation, serving as a primary preventive strategy for long-term skeletal health.
