About 80% of people do not get enough vitamin D every day. But this vitamin is very important for your health.
大约80%的人每天得不到足够的维生素D，但这种维生素对你的健康非常重要。

Vitamin D is really important for our bones. When we are young, vitamin D builds up our bones and makes them strong. When we are older, we still need vitamin D to keep our bones strong. Our bodies keep the vitamin D in our bones and teeth. Then we lose vitamin D as we work and exercise during the day. But our bodies can’t make vitamin D. So we have to get it from outside of our bodies.
维生素D对我们的骨骼非常重要。当我们年轻的时候，维生素D会构建我们的骨骼并使它们变得强壮。当我们变老的时候，我们仍然需要维生素D来保持我们的骨骼强壮。我们的身体将维生素D保存在骨骼和牙齿中。然后我们在白天工作和锻炼时会失去维生素D。但是我们的身体不能产生维生素D，所以我们必须从我们身体外获得它。

Where can a person get this very important vitamin? Vitamin D is in foods like fish and eggs. Sometimes, vitamin D is added to bread, milk, and orange juice. Food is not the only way our bodies can get vitamin D. The sun also gives us vitamin D. If we want to be healthy, we should spend some time in the sun each day. Too much sun is not good for you, but about 15 minutes a day is usually enough. And we should be sure to eat foods that are rich in vitamin D, too.
一个人从哪里可以获得这种非常重要的维生素？维生素D存在于鱼和蛋等食品中。有时，面包、牛奶和橙汁中会加入维生素D。食物不是我们身体获得维生素D的唯一途径。太阳也给予我们维生素D。如果我们想要健康，我们应该每天花一些时间在太阳下。阳光照射过多对你不好，但一天大约15分钟就足够了。而且我们一定要吃一些富含维生素D的食物。
