Pure water can be drinkable for a long time

面对水污染，有人使用了净水设备，选择饮用纯净水。但是，社会上的各种说法，又让大家有点担心：纯净水能否长期饮用？

In the face of water pollution, some people use water purification equipment and choose to drink pure water. However, all kinds of social statements make you a little worried: can pure water be drunk for a long time?

我把这些说法归纳了一下，主要有两点，一是说纯净水里面没有了矿物质和微量元素，长期这样会导致人体内缺乏这些元素。二是说纯净水是“刮骨水”，会把身体里面的有用物质带出体外，从而形成对身体健康的伤害。

I summed up these statements. There are two main points. One is that there are no minerals and trace elements in pure water, which will lead to lack of these elements in the human body in the long run. Two is that pure water is "scraping bone water", which will bring out the useful material inside the body in the body, so as to form the harm to the health of the body.

针对第一个说法，水里面的矿物质和微量元素即使是全部被人体吸收，所占的比例也是相当的少，不足1%吧。而且，最重要的是，我认为，人体很难吸收这些以无机状态存在于水中的各种物质。

In the first view, the mineral and trace elements in the water are absorbed by the human body, and the proportion is less than 1%. And, most of all, I think it's hard to absorb all of the substances in the water that are in the inorganic state.

打个比方，人体如果缺钙、缺铁、缺某些微量元素，医生会只叫你均衡膳食，多喝牛奶、多吃牛肉、豆制品、水果等等，不会叫你去多喝水，更不会叫你多喝含有水垢、铁锈的水。

For example, if the human body is short of calcium, iron and some trace elements, the doctor will only call you a balanced diet, drink more milk, eat more beef, soy products, fruits and so on, will not ask you to drink more water, and will not drink more water containing scale and rust.

针对第二个说法，我们仔细想一下，纯净水喝到肠胃里面会是个什么情况，由于水的溶解性，会与肠胃里面的各种物质、液体立即混合在一起，那么，它还是纯净水吗？特别需要明确的是，水越纯净，混合的越快、越彻底。

In view of the second statement, let's consider carefully what kind of water the pure water will take to the intestines and stomach. Because the solubility of water will immediately mix with all kinds of substances and liquids in the intestines and stomach, is it still pure water? It is particularly clear that the more pure the water is, the faster and more complete the mixture is.

哪些认为纯净水是所谓“刮骨水”的人，僵化地以为纯净水喝进人体的肠胃后，纯净水还是纯净水，其它物质还是其它物质，各行其道，然后纯净水所到之处，刮走人体内有用的物质。

What is that pure water is the so-called "scraping the bone to water", the rigid thought of clean water to drink in the body of stomach, pure water or pure water, other substances or other substances, separately, then pure water everywhere, blown away the body of useful substances.

我们姑且认为纯净水会刮去这些物质，但是，纯净水一旦进人肠胃里面，它已经就不是纯净水了，还能刮吗？如果还能，那自来水不是一样刮吗？

We think that the pure water will scrape these substances, but, once the pure water enters the stomach of the stomach, it is not pure water, can it be scraped? If still, then the water is not the same shave?

所以说，这个说法，虽然很容易忽悠人，但是，我们一认真思考，真相就出来了。

So, this statement, although it is easy to flicker, but when we think seriously, the truth comes out.

人体本身是个确保新陈代谢的精密机器，吸收营养排出废弃物是体内相关器官的基本功能，因此，排出体外的只会是对身体无效的废弃物。

The body itself is a precision machine that ensures the metabolism. The absorption of nutrients and excretion is the basic function of related organs in the body. Therefore, the excretion of the body will only be useless for the body.

我们可以朴素地想象一下，人体的70%是由水组成的，就现在的水污染状况，水越干净，就意味着进入人体的有害物质就越少，因此，我认为，纯净水可以长期饮用！

We can simply imagine that 70% of the human body is made up of water. Now the water pollution situation, the more clean the water, the less harmful substances to enter the human body. Therefore, I think that pure water can be consumed for a long time.
