本文的重点是钙（Ca）的摄入对终身骨骼健康的重要性。钙是骨量的主要组成部分，如果钙摄入不足或每日钙流失过多，生物体就不能建立或维持基因蓝图中所要求的骨量。确保足够钙摄入量的重要性在雌激素方面得到了最明显的证明。与以脂肪形式储存的能量不同，身体不能储存过多的钙。随着年龄的增长，适应低钙摄入的能力基本上消失了。老年人无法适应次优摄入量，这揭示了对每个人来说最好、最安全的钙摄入量。
The article focuses on the importance of calcium (Ca) intake for lifelong skeletal health. Calcium is a major component of bone mass and the organism cannot build or maintain the skeletal mass called for in the genetic blueprint if Ca intake is insufficient or daily calcium losses are excessive. The importance of ensuring an adequate Ca intake has been shown most clearly for estrogen. Unlike energy, stored as fat, the body cannot store an excess of Ca. With advancing age, ability to adapt to low Ca intake largely disappears. The inability of the elderly to adapt to suboptimal intakes uncovers the intake of Ca that may be best and safest for everyone.
