Drink mineral water or pure water? Discuss about the stupid tax of drinking water.

Water is the source of life and maintaining the normal function of our body is inseparable from the participation of water. Purified water, mineral water... In today's dazzling array of commodities, it has become a complicated matter for people who have difficulty choosing what water to drink.


So, what is the difference between pure water and mineral water?


Pure water refers to water that does not contain minerals and any impurities. Generally, we can obtain pure water after a series of treatments such as coarse filtration, fine filtration, reverse osmosis, and disinfection. Among them, reverse osmosis uses a semi-permeable membrane with a pore diameter equivalent to that of water molecules to filter water under pressure. The pressure allows water molecules to pass through, while substances with a diameter larger than that of water molecules cannot pass through the pores of the semi-permeable membrane.


There are two main types of mineral water on the market: mineral water and mineral spring water. Both are water containing minerals, and the difference is that mineral water is a certain proportion of purified and filtered water added to the water with mineral components. Mineral spring water is water taken out from underground rock formations, and has undergone preliminary settlement, filtration, and disinfection, and the type and content of minerals in it are the same as those in the underground rock formations.


Minerals in water generally include calcium, magnesium, potassium, sodium, lithium, strontium, etc. These mineral elements are necessary for the normal growth and development of our body and for maintaining good health. Some animal experiments have even proved that the electrolytes excreted from the body of rats who drink purified water for a long-time increase, and there is a risk of inducing cardiovascular disease. Therefore, some opinions on the Internet believe that drinking pure water is not good for health, should you drink water containing minerals?


Let's first look at how many minerals can be replenished by drinking water. Generally speaking, the content of zinc and iron in 1000 ml of water is less than 0.2 mg, and adults need to supplement 10-15 mg of zinc and 12-18 mg of iron every day. Assuming that everyone drinks 5 liters of water a day, the daily intake of these minerals from water is less than 1 mg, which is insignificant compared to the amount required by the human body.


In fact, in addition to getting these minerals through drinking water, the food we usually eat can also provide us with minerals. In today's increasingly diversified daily diet, our daily food sources are very rich, and each food contains its own unique minerals. We can completely supplement the minerals our body needs through a variety of foods.
