Contrary to popular belief, our framework of bones isn’t a rigid and unchanging structure. Each year, our bodies replace about 20 percent of our bones’ tissue, which means that our activities at every age influence their health. Sections of old bone break down, creating gaps to be filled by new bone. Until about age 30, we build bone very efficiently, so making the right health moves, such as exercising and getting enough calcium, helps your bony framework reach its genetically determined peak strength.
Think of your bones as a retirement fund: The more you deposit when you’ re young, the better off you will be in later years, when you need to draw on your reserves. The problem is that kids prefer soda to a glass of milk: they are coming up short of the calcium and vitamin D they need to build up good health. Many of them also lead an inactive life, so they aren’t getting the bone-building benefits of regular exercise either. That’ s a problem every parent should be concerned about.
选项
答案
与流行的观点相反,我们的骨架并非是坚硬不变的结构。我们身体每年置换20%的骨头组织,这意味着我们每一年龄的活动都影响骨骼的健康。部分旧骨分解(失去功能),产生空白由新骨来填补。大约30岁之前,我们造骨的效率很高,所以采取适当的保健措施有助于骨架达到遗传决定的峰值,如锻炼和摄入足够的钙。 把骨头看作是养老金。你年轻时储蓄得越多,以后需靠储蓄生活时日子就越好过。但问题是儿童喜欢喝汽水,而不是一杯牛奶,他们缺乏健康所需的钙和维生素D。他们中许多人缺乏运动,也无法享受经常锻炼给造骨带来的益处。这正是每个家长应予以关注的问题。
