Eight glasses of water every day is a healthy code of conduct believed by many people, so the first thing for many people to get up is to drink water. Water is the source of life, which accounts for the majority of the body. In the body of a baby, water accounts for as much as 70% - 80% of its weight. For a baby, water is also crucial. So what kind of water does a baby drink? A baby drinks pure water for a long time Can stone?
It is traditionally believed that mineral water, which is rich in mineral salts and trace elements, is the nutrient needed by human body. Children are in a critical period of growth and development, and they need to supplement these microelements. Therefore, it is convenient to obtain them directly from drinking water, which is also conducive to absorption. What do many parents want to do instead of doing? Therefore, it is not uncommon for children to drink mineral water, and it has become a fashion move.
In response to this phenomenon, medical experts have put forward a warning: mineral water with high mineral content will threaten the health of infants!
In junior high school physics class, we have learned that water can migrate from low concentration to high concentration through the principle of infiltration. When drinking water, the concentration of body fluid is higher than that of drinking water, forming a potential energy difference. Water can pass through the cell membrane and be naturally absorbed by cells.
However, when there are more minerals in the water and the concentration of water is higher, the potential energy difference will be reduced or even reversed, which will bring trouble to the absorption of water supply. But don't panic. Besides the permeation principle, the absorption of human body can also be carried by some proteins in the cell, such as the ferry boat, which actively transports the required substances from the outside to the cell. This physiological process can not be affected by the concentration difference.
The physiological structure of infants is quite different from that of adults, the development of digestive system is not complete, the filtering function is poor, and the mineral content in some mineral water is too high, which is a big problem for infants. When the baby uses mineral water to brew food or drink directly, it is easy to increase the osmotic pressure of food and increase the burden on the kidney.
In addition, the element content of mineral water is basically designed according to adult standards, and its content and proportion are a little high for infants, especially some elements are harmful to infants.
Can't give the baby mineral water, is it better to give the baby pure water? This is still wrong. The purified water after secondary processing is also not suitable for the digestive system of newborns. Drinking purified water for a long time will also make children lack some minerals, and some industrial raw materials used in the purification process of purified water may have adverse effects on the liver function of infants.
So what kind of water is most suitable for children? According to research, tap water is best for health when it is boiled and then cooled to room temperature. After boiling, the gas contained in the water is reduced by half, and the cohesion between water molecules is increased, which is closest to the characteristics of water in human cells, so it is easy to be absorbed by human body through cell membrane. It is worth noting that it is not suitable to boil water in an aluminum pot, otherwise, excessive intake of aluminum ions will affect the bone and nerve development of the baby; the water dispenser is easy to cause secondary pollution, and it is not suitable to use.
