What is the best choice for long-term drinking water?

Regarding the question of what water to drink, some people think that they should drink mineral water because they can supplement various minerals. Some people think that drinking pure water is better because it can avoid the intake of various impurities. Others believe that tap water can be boiled directly. Which kind of water is better to drink?

Mineral water is water that naturally emerges from the depths of the earth or is collected by drilling. It contains a certain amount of minerals such as calcium, magnesium, potassium, sodium, metasilicate, zinc and selenium. The state has requirements for the content of some trace elements, such as zinc must be greater than or equal to 0.2 mg / liter, and selenium must be greater than or equal to 0.01 mg / liter.

Drinking mineral water can supplement these minerals to a certain extent compared to pure water, but the amount that can be added is very limited.
ure water is water that is directly derived from the surface, underground or public water supply system, and is produced by a suitable water purification process. Some minerals and some impurities will be removed during processing.

It is precisely because of this that some people think that drinking pure water can prevent disease and cure diseases. In fact, this is not scientifically justified. Whether it is pure water or mineral water, as drinking water, it can exert various physiological functions such as participating in human metabolism, maintaining normal osmotic pressure of body fluid and electrolyte balance.
Boiled water is generally water directly boiled from tap water. This water is not only cheap, easy to obtain, but also safe and hygienic.
All in all, whether it is boiled water after boiling water, or packaged mineral water or pure water, can be used as a source of our drinking water, but from the perspective of cost performance, it is most economical to drink boiled water.
