Anyone who has ever had a kidney stone knows that trying to get rid of it can be one of life's more uncomfortable experiences.
曾经得过肾结石的人都了解去除肾结石的过程是人这一生中最难受的经历之一。

So if you're prone to having kidney stones, it's wise to do what you can to prevent them.
所以如果你很容易得肾结石，最好是采取一切措施来预防。

And lemonade, or just lemon juice, turns out to be one of the better ways.
喝柠檬水或柠檬汁是比较好的方法之一。

Lemons are full of citrate – a chemical that attached to calcium in the kidney and stops it from forming crystals that can turn into stones.
柠檬中含有大量柠檬酸盐——这种化学物质和肾脏中的钙有关，可阻止钙结晶形成结石。

If you want to prevent kidney stones but aren't partial to sugary lemonade, drinking just plain lemon juice mixed with water works as well.
如果你想预防肾结石，但又不喜欢含糖的柠檬水，那么喝兑水的纯柠檬汁也能达到同样的效果。

And if you don't like lemons at all, then try drinking lots of fluids and eating less salt, calcium, and protein.
如果你根本就不喜欢柠檬，那就多喝水，少吃盐，限制钙和蛋白质的摄取量。
