答案
The Importance of Calcium Calcium is a mineral that helps build strong bones and teeth and regulates muscle contraction. / Milk and dairy products have long been held as an important source of calcium. / In addition to calcium, Vitamin D is important / because it helps the body absorb and retain calcium in the bones, making them strong. / Similarly, sufficient exercise is now seen as another vital factor / in maintaining healthy bone structure and density. / Concerns have been voiced that a lack of exercise in growing children / will have a detrimental effect on their bones. / Calcium can continue strengthening your bones / until the age of 20 to 25 when peak bone mass is reached. / After this point, your bones can only maintain or lose their density / and grow weaker as a natural part of the ageing process. / Inadequate dietary calcium intake before this age / can increase the risk of brittle bone disease, / as calcium is drawn from the bones as a reserve. /
解析
钙的重要性
钙是一种矿物质,有助于坚固骨骼和牙齿,并调节肌肉收缩。牛奶和其他乳制品是钙的重要来源。在20~25岁之前,补充钙质可以促进骨骼的发育。否则,随着年龄的增长,骨骼会变得越来越脆弱,并引发各种骨骼疾病。
