Mineral water, deep groundwater, contains essential trace elements for human body. In theory, regular drinking is harmless to human health. However, mineral water is generally bottled water, mainly in the packaging process, and bromate may exceed the standard. Bromate is a kind of 2B potential carcinogen, so it is risky to drink it frequently. Generally speaking, bottles filled with mineral water are theoretically made of food-grade plastics, but they still contain polyethylene and other ingredients. During transportation, if the temperature is too high, polyethylene will dissolve and enter the water, releasing an organic solvent and particles, which is harmful to human health.
Pure water is water without impurities. In the production process, viruses, bacteria and organic substances harmful to human body are removed. But at the same time, some trace elements and minerals that are beneficial to the human body have also been removed. Drinking pure water for a long time, the body will lack electrolytes and mineral elements, and it is prone to diseases such as osteoporosis and high blood pressure. However, in our daily diet, we will take electrolytes and necessary trace elements from different foods. Therefore, as long as the diet is reasonable and healthy, drinking pure water for a long time has little effect on our health.
Tap water, many people will think that chlorine is added to tap water, although it has disinfection and sterilization effect, it is a harmful gas. In fact, this kind of worry is unnecessary. The tap water is treated and meets the standard. We all drink boiled water. However, if the water is boiled for a long time, the scale in the kettle will only affect the taste and there will be no safety problems. Soaking in white vinegar can remove scale.
It can be seen that boiled tap water is more economical and safer than mineral water and pure water, and can also provide mineral elements such as calcium for the body. For mineral water and pure water, you can drink it occasionally, and it is not recommended to drink it for a long time.
