Pure water is water without impurities and bacteria, which can be directly drunk, so many parents think that it is healthier to drink this kind of water for their babies, but it is not necessarily so. Drinking a lot of processed pure water for a long time may make children lack some minerals (calcium, magnesium, potassium, sodium, sulfur, etc.). ).
Although the total amount of minerals in human body is less than 5% of body weight, it plays an important role in human tissue and maintaining normal physiological functions, but it cannot be synthesized by itself in the body and must be supplied by the outside world. Comparatively speaking, the contents of minerals and trace elements are more suitable for people who drink "cold boiled water".
Extended data:
Water is an important part of human body, and the liquid content in adults accounts for about 55%~60% of body weight. According to Wu Fan, deputy chief physician of pediatrics in the Third Affiliated Hospital of Guangzhou Medical University, the proportion of newborn babies is 78%.
Newborns have a physiological weightlessness period, that is, 2 ~ 3 days after birth. Due to the discharge of meconium, the absorption of fetal fat and the loss of water, as well as the weak sucking ability and less breastfeeding of newborns, temporary weight loss may occur, even lower than the birth weight.
After "physiological weight loss", the water content in the baby's body can also account for more than 65%. Generally, after the age of 8, the water content in children accounts for about 60% and begins to approach the adult level.
Although children are small and have a relatively high percentage of water in their bodies, they are in the period of growth and development, with a large amount of activity, vigorous metabolism, rapid water excretion and faster breathing frequency than adults, making "not obvious dehydration" far more than adults.
Therefore, it is particularly important to replenish enough water every day, which is the basis for children to maintain abundant physical strength, brain power and health every day.
