Nutritional aspects of the bone mineral accruals during childhood were discussed. Calcium is the most important mineral for bone and large number of studies has been performed to clarify the effects of the calcium supplement on bone strength or bone mineral gain during childhood. One recent meta-analysis showed that calcium supplement has only minor effect on bone mineral accruals. But the effects seemed to be larger in the group whose basal calcium intake was small. In Japan, basal calcium intake is low. Thus we should be careful to evaluate the effects of calcium supplement on bone. Vitamin D is another important nutrition. Food restriction, especially fish and egg yolk, is the major cause of vitamin D deficiency in Japan.
讨论了儿童期骨矿物质积累的营养方面。钙是对骨骼最重要的矿物质,已经进行了大量研究以阐明补钙对儿童期骨骼强度或骨矿物质增加的影响。最近的一项荟萃分析表明,补钙对骨矿物质积累的影响很小。但在基础钙摄入量低的人群中,这种影响似乎更大。在日本,基础钙摄入量较低。因此,我们在评估补钙对骨骼的影响时应谨慎。维生素D是另一种重要的营养素。食物限制,尤其是鱼类和蛋黄,是日本维生素D缺乏的主要原因。
