Li Fuxing, a water nutritionist, said that although pure water is clean, there may be some hidden dangers to human body. This kind of water, which does not exist in nature, is a kind of degraded water. Its water quality has declined and its effect on human body has been "degraded". Even unpolluted natural water, after a series of purification processes such as reverse osmosis, has extracted all mineral elements from the water, and will lose its supporting structure and "degenerate", losing its physiological function because there are no mineral elements. After all, pure water is the clearest stagnant water and has no activity. The so-called "clear water means no fish" is because too clear water contains very few minerals, which is not conducive to biological growth. It is the same for people to drink water. Drinking pure water for a long time will reduce the immune function of the human body and make some beneficial nutrients in the body lose. Old people, especially those with cardiovascular diseases and diabetes, children and pregnant women should not drink this water for a long time.

Long-term use of pure water is not good for your health. Although it seems that pure water is very convenient to use, from the process flow of pure water, although it is pure after many times of purification, it also filters out minerals that are beneficial to your body while filtering impurities. In this way, people can't supplement some necessary minerals like drinking tap water when drinking water, and living like this for a long time is not good for their health. Therefore, it is recommended to use the most common method-burning tap water to drink. Although it is troublesome, the high-temperature sterilized tap water does not contain bacteria, but also retains minerals useful to the human body, which is beneficial to the body.
