Is it okay for children to drink mineral water?

　　Nutrition experts have a certain point of view, because mineral water is hard water, which is not conducive to the baby's absorption and can easily harm the baby's body. healthy , so mineral water is not suitable for children to drink.

　　Hard water can also harm your baby

　　There is a reason why we often use the word "watery" to describe babies. exist baby In the body, water accounts for up to 70% to 80% of its body weight, which is much higher than the 60% of adults, which is even more important for babies.

　　We traditionally believe that mineral water is mined from deep underground and is rich in mineral salts and trace elements, which are nutrients needed by the human body. Children are in a critical period of growth and development and need to supplement these trace elements. So getting them directly from drinking water is convenient and easy to absorb. Why not? Therefore, it is not uncommon for Ms. Zhang to choose to give her baby mineral water, and it has become a fashionable move.

　　Recently, in response to this phenomenon, Bulgarian medical experts have issued a warning: Mineral water with high mineral content can threaten the health of babies!

　　This starts with the principle of water absorption. In junior high school physics class, we learned that water can migrate from low concentration to high concentration through the principle of osmosis. When drinking water, the concentration of body fluids is higher than that of drinking water, forming a potential energy difference. Water can pass through the cell membrane and be naturally absorbed by the cells.

　　But when the water contains more minerals and the water concentration is higher, this potential energy difference decreases or even reverses, which brings trouble to the absorption of water. Just like a flower inserted into a cup of concentrated salt water, not only will the flower be unable to absorb water, but it will also become dehydrated and dry up. This is because the concentration of water in the body is not as good as the outside world, and the potential energy balance is broken, causing body fluids to leak out.

　　At this time, you may be anxious: If this is the case, wouldn’t we be unable to drink thicker drinks and soups? There is no need to worry about this, because in addition to the principle of osmosis, the body's absorption can also be carried out through the transport of some proteins in the cells, like a ferry boat, actively transporting the required materials from the outside to the cells. This physiological process is not affected by concentration differences.
