2. The main difference between pure water and mineral water lies in various ions. Of these two kinds of water, the best should be mineral water, followed by pure water. However, mineral water should not be boiled for drinking. Drinking purified water for a long time may lead to the lack of trace elements. You can choose the most suitable drinking water according to your own situation.
1 In fact, pure water is safer than tap water because it can remove harmful minerals such as lead, mercury and arsenic. This is also the selling point of many pure water manufacturers. There are no heavy metals in our water, so there is no pollution, which is very healthy for human body. In fact, we have said that as long as the tap water quality meets the sanitary standard of drinking water, long-term drinking will not cause obvious harm to the body. One disadvantage of drinking pure water for a long time is that there may be a lack of minerals, such as calcium, magnesium, iron and zinc. These trace elements are very important to human beings. Minerals cannot be synthesized by themselves and need to be supplemented from food or water. The minerals in food mainly come from meat and grains. If you are a picky eater or a person with poor gastrointestinal absorption, drinking pure water for a long time may lead to mineral deficiency and malnutrition.
2. Natural mineral water is unpolluted underground mineral water that gushes naturally from deep underground or is exposed artificially. The nine limit indicators specified in the national standard include lithium, strontium, zinc, selenium, bromide, iodide, metasilicic acid, free carbon dioxide and total dissolved solids, and one or more of them must meet the requirements of limit indicators in mineral water. The advantage of mineral water is that it contains trace elements necessary for human body. Moreover, the trace elements in water exist in the form of ions, which are easy to be absorbed, and the absorption rate of trace elements dissolved in water is as high as over 90%. However, mineral water should not be boiled for drinking. After boiling, calcium ions and magnesium ions form calcium carbonate, which is precipitated from water.
