On the one hand, purified water filters out harmful substances in water, on the other hand, it also filters out minerals and trace elements beneficial to human body. Low ion content, low hardness of water and almost no minerals. It will not form scale when used to boil water, but long-term drinking may cause the lack of trace elements, reduce human immunity and increase the risk of cardiovascular and cerebrovascular diseases. Athletes, steel workers and other people who exercise a lot and sweat a lot should not supplement a lot of pure water because they can't absorb trace elements such as sodium. Very clean, but lack of nutrition, it is not recommended to drink for a long time.
Distilled water has many advantages, but it varies from person to person. Made by distillation or other multi-layer filtration process, it can not only remove harmful substances and microorganisms, but also remove minerals such as potassium, calcium and magnesium. Tap water contains cyanide and volatile phenol, which is volatile. These two substances will be concentrated during distillation. For kidney calculi's patients, it is best to choose distilled water without minerals. For healthy people, drinking too much distilled water is not recommended. Without mineral elements, cyanide and volatile phenol can be easily found.
It can be seen that no matter what kind of water has its own advantages and disadvantages, and generally it varies from person to person, and everyone has a water quality that is more suitable for them.
