【英语时差8,16】骨质疏松-下（在线收听）

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 calcium–bones will become brittle. 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 intestine to increase its calcium uptake, bypassing the need to grab extra from the bones. Under a doctor’s supervision, 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 prey to the body’s own mechanisms in later age.
