From the point of view of health, this paper puts forward some views or suggestions on how to correctly choose drinking water (tap water, mineral water, purified water, distilled water, etc.). )

The sanitary standard of tap water in China is very high when it leaves the factory, but one is residual chlorine pollution and the other is pipeline pollution. It is best to boil it before drinking.

Barreled mineral water still has the problem of secondary pollution. Even if it is natural, there may be problems such as biological pollution and heavy metal pollution.

Pure water and distilled water need not be considered, and lack of basic mineral elements is not suitable for long-term drinking.

Ordinary people usually have little problem drinking mineral water or boiled tap water on weekdays.
