Natural and pollution-free mountain spring water, of course. Because most urban water comes from big rivers, it is purified, disinfected, bleached and precipitated before being sent to water pipes. For public reference. The river water has been disinfected and purified, but there are also a small amount of residual components of disinfection chemicals here. The spring water in the mountains is not clean. Therefore, there are many trace elements in spring water in the mountains, which can't be compared with tap water. Mountain surge is the best fresh water for human beings.
One side feeds the other, and generations have lived by drinking mountain spring water. The mountains around our village are steep, and large and small springs flow under our feet. There is a trickle of spring water in the crack of the big root. People drank it, used it and cooked it, but it was not delicious. It smells like wood. Another spring is tasteless, and we grew up eating it. This spring water is boiled in a teapot in winter, and there is no white alkali at the bottom of the teapot after one year. Now I'm in town, and there's a thick layer of alkali on the bottom of the pot. The cooked rice soup is not delicious. We still think that spring water in mountainous areas is very healthy for people. Pure water contains no minerals, which is not conducive to human health. But minerals can indeed be supplemented from food, so it is more appropriate to say that drinking pure water is no different from drinking cold white.
The water quality can only be determined after passing through water quality inspection. Some inorganic salts and minerals in mountain spring water do not meet the needs of human health, harmful substances exceed the standard, or trace elements are insufficient. It is not good to drink these mountain springs for a long time. For example, in some areas, if the fluorine content in spring water exceeds the reference value, it will become a bone and joint disease. Depending on the substances contained in the water, it may also lead to macular teeth, human deformities and congenital stagnation. There is also water with calcium, magnesium, sulfur and other elements exceeding the reference value, which is very thirsty and difficult to swallow. Not only can thirst be solved by drinking water, but trace elements not contained in food can also be ingested by drinking water. Therefore, drinking pure water can lead to diseases such as chondrosis.
