is tap water first, which can be directly consumed in many countries, such as the United Kingdom. But the tap water in the UK is harder, which means it contains more soluble calcium and magnesium compounds . Hard water does not cause harm to the body, but it is generally reported that drinking tap water directly in the UK will cause the hairline to shift. If this is true, perhaps we have discovered the reason why the British prince’s hairline is getting higher and higher.
The tap water in our country cannot be directly drunk. In fact, it is okay to drink directly. However, our country's pipelines are not dedicated direct drinking water pipelines. Problems such as aging of the tap water pipelines and secondary pollution of the water in the pipelines will inevitably occur. In addition, our country has the habit of drinking hot water, so the most we drink is plain water.
Boiled water is water that can be consumed by humans after being purified and disinfected by a water plant. In order to prevent water-borne diseases, the tap water in our country will be chlorinated and disinfected, and no harmful substances will be deposited.
my country has a vast territory, and the amount of tap water varies slightly from place to place. Tap water usually contains more soluble calcium and magnesium compounds, called " hard water ", which can be "softened" after boiling. Therefore, drinking plain water will not harm human health, but is beneficial to humans.
Purified water is water without any impurities, called "pure water" or "pure water". The processing method is complicated, and it is made by appropriate processing methods such as electrodialysis, ion exchange, reverse osmosis, and distillation.
Pure water can be consumed directly, but it does not contain any minerals. Although pure water can be drunk, do not drink pure water all the time. This is because pure water is easier to dissolve than ordinary water and can dissolve minerals in the human body, leading to calcium deficiency in the human body.
But precisely because pure water is highly soluble, it is generally difficult to produce pure water. The pure water produced in general is not the standard for pure water at all. Only a laboratory can produce pure water. However, the taste of 100% pure water is not good, and long-term drinking is not good for the human body. The pure water on the market is not pure water, so don't worry about this problem.
Mineral water is water containing various trace elements.As we all know, the rocks on the earth are rich in various minerals. These minerals will flow into rivers through the erosion of wind and rain, making the water rich in mineral elements such as calcium, zinc, manganese, and iron.
Generally speaking, the mineral water we are talking about refers to the natural unpolluted mineral water that is directly extracted from deep underground or lakes. Since it is formed naturally, the type and concentration of minerals will vary with the season, temperature and rainfall.
my country stipulates that mineral water can be called mineral water only if its mineral content meets certain index requirements. This also makes real mineral water very scarce.
But long-term drinking of mineral water is not very good for the human body, because although the human body needs minerals, some minerals cannot be absorbed by the human body. In addition, if there are too many minerals in the body, it will cause the accumulation of minerals and affect health, such as stones.
If you have to choose one of the above four types of water, it is best to choose boiled water, because it is cheap, convenient and easy to get. Boiling water can remove excess minerals and soften the water quality.
Actually, with so much water on the market, which kind of water you drink has little effect on the human body. The water sold on the market side has passed the national drinking water standard and will not harm human health. Furthermore, water only replenishes body fluids, helps the body metabolize wastes in the body, and has no other effect.
And drinking water is mainly to supplement water, not to supplement trace elements, nor to supplement nutrition. The nutrients and trace elements needed by the human body should be obtained mainly from food, not from water.
