近年来，人们普遍认为维生素 D 对于骨骼健康至关重要。然而，一个国际团队最近在儿童中开展的一项大规模随机对照试验却发现，维生素 D 补充剂并不能预防儿童骨折。这一研究结果挑战了人们此前普遍认为的维生素 D 有助骨骼健康的看法。
根据研究结果显示，维生素 D 补充剂并不能增加维生素 D 缺乏症儿童的骨骼强度或预防骨折。这意味着，我们可能需要重新审视维生素 D 在骨骼健康中的作用。
事实上，维生素 D 补充剂并不能完全替代阳光照射的作用。阳光照射是人体维生素 D 的主要来源，对于骨骼健康至关重要。因此，即使在维生素 D 补充剂中，儿童也应该每天接受足够的阳光照射，以保持骨骼健康。
总的来说，这项研究结果提醒我们，维生素 D 补充剂并不能完全替代阳光照射的作用，阳光照射仍然是维护骨骼健康的关键。

翻译内容：
In recent years, people have commonly believed that vitamin D is essential for bone health. However, a recent study conducted by an international team has shown that vitamin D supplements do not prevent fractures in children. This research result challenges the previous belief that vitamin D is beneficial for bone health.
According to the research results, vitamin D supplements do not increase the bone strength of vitamin D-deficient children or prevent fractures. This means that we may need to reevaluate the role of vitamin D in bone health.
In fact, vitamin D supplements cannot replace the role of sunlight exposure in providing vitamin D. Sunlight is the main source of vitamin D in the body, and it is essential for bone health. Therefore, even in vitamin D supplements, children should still receive enough sunlight exposure to maintain bone health.
Overall, this study result reminds us that vitamin D supplements cannot completely replace the role of sunlight exposure in maintaining bone health. Sunlight exposure is still the key to maintaining bone health.
