【英语时差8,16】骨质疏松-下

（单词翻译）

Which is just what happens. This is a great short-term fix, but what about the poor skeleton? Eventually it will suffer from the loss of its own calcium¹–bones will become brittle². What can we do? Two things. Help your body get more calcium by eating fatty fish and vitamin-D rich dairy products. Why vitamin D? Because that causes the small intestine³ to increase its calcium uptake, bypassing the need to grab extra from the bones. Under a doctor’s supervision⁴, calcium tablets might also be helpful, along with the old standard–more exercise. Weight-bearing exercise helps keep bones strong and less likely to fall prey⁵ to the body’s own mechanisms⁶ in later age.
