The content of mineral water in mineral water is basically designed according to adult standards. Its content and proportion are not suitable for infants, especially certain elements are also harmful to infants.
When Mama learned she was too child-bearing, Ms. Zhang had learned from her baby since her arrival. This does not, to add complementary food to the baby, but what water should be used, but it has taken a lot of thoughts, always worried that the tap water is not clean enough, and cook up inconvenient. In a childcare forum, this puzzle was discussed. One of the mothers gave a secret - the use of mineral water is not only convenient, safe, and clean, but also helps the child to supplement minerals and enhance appetite. The cherished love of Ms. Zhang, such as treasure, specifically to the supermarket to buy back a box of mineral water, whether it is rushed milk powder or rice flour, just use the electric kettle to heat it, you can brewed into the water. Convenience is convenient, but Ms. Zhang is faintly worried: Is it appropriate to give your baby mineral water?
Hard water can also hurt the baby
We often use "water spirit" to describe our baby. There is a reason for this. In infants, water accounts for up to 70% to 80% of body weight, far more than 60% of adults. It is even more important for infants.
We traditionally believe that mineral water is collected from the depths of the ground and is rich in mineral salts and trace elements. It is a nutrient required by the human body. The child is in a crucial period of growth and development, and it is in need of supplementing these trace elements. Therefore, it is convenient and conducive to absorb it directly from drinking water. Why not? Therefore, it is not uncommon for Ms. Zhang to choose to give her baby mineral water, and it has become a fashion move.
Recently, Bulgarian medical experts have warned against this phenomenon: Mineral water with high mineral content threatens the health of the baby!
This starts with the principle of water absorption. In junior high school physics classes, we learned that water can migrate from low to high concentrations through the principle of infiltration. When drinking water, the body fluid concentration is higher than drinking water, forming a potential energy difference, the water can pass through the cell membrane, naturally absorbed by cells.
However, when the water contains more minerals and the concentration of water is higher, the potential energy difference is reduced or even reversed, causing troubles for the absorption of water. Just as a flower is inserted into a glass of salty water, the flowers not only cannot absorb water, but also cause the dehydration to become dry - this is because the concentration of water in the body is not as good as the outside world, and the balance of potential energy is broken and the body fluid is oozing out.
At this time, you may be anxious: If this is the case, then aren't we unable to drink stronger drinks and soups? This does not need to worry, because the body's absorption in addition to the principle of infiltration, but also through the transport of some of the protein within the cell, like a ferry boat, actively transport the required substances from the outside to the cell, the physiological process can be independent of concentration The effect of the difference.
Pushing water easily and boating backwards is a passive and natural process. It requires little energy consumption, and active transport requires a relatively large amount of energy. The physiological structure of infants is quite different from that of adults. The development of the digestive system is still incomplete, and the filtering function is poor. The mineral content in mineral water is too high, which is a big problem for infants. When the baby uses mineral water to brew food or drink it directly, it can easily cause the food to increase its osmotic pressure and increase the burden on the kidneys.
In addition, the mineral water element content is basically designed for adult standards, and its content and proportion is not suitable for infant intake, especially certain elements are also harmful to infants. For example, Germany issued a notification on November 22, 2006, amending the Natural Mineral Water, Spring Water and Restaurant Water Act. This revision is based on the consideration of the increasing use of natural mineral water in infants' semi-finished foods, following a survey and assessment of the uranium content in natural mineral water and the risks posed to health. The ordinance limits the content of uranium and must be specified in the label or advertisement of baby semifinished food.
Baby drinking, soft and hard to eat
The hardness of mineral water is measured by its mineral content. In general, mineral water below 50 milligrams per liter of minerals is called "ultra-low mineral content"; 50-500 mg is "low mineral content," this mineral water has a softer, slightly sweet taste. Most of the mineral water minerals in drinking water are between 500 and 1500 mg; more than 1500 mg per litre is called “high mineral content†mineral water, which is mostly used in sports, saunas and other human body to lose more minerals. in the case of.
Bulgaria’s pediatrician Masalaska pointed out that for infants and young children, the mineral content per liter of water should not exceed 100 milligrams, with sodium being less than 20 milligrams and fluorine being less than 1.5 milligrams. Above this threshold, it may pose a threat to the newborn’s kidneys. Obviously, most mineral waters are too "hard" for children.
Some parents may ask, is it better if I give my baby pure water? The answer is still "NO"! After the second processing of pure water is also not suitable for the newborn's digestive system. As mentioned before, the difference in concentration between cells inside and outside is the driving force for the formation of water through osmotic absorption. The mineral content of pure water is too low, resulting in a large gap between the two, and it can also cause absorption disorders. In addition, drinking pure water for a long period of time can also make children lack certain minerals, and some industrial raw materials used in the purification process of purified water may have adverse effects on the liver function of infants and young children.
Since soft and hard do not eat, what kind of water is best for children? According to research, tap water boils and then cools to room temperature, which is most conducive to health. After the boiled water, the gas contained therein is reduced by half, and the cohesive force between the water molecules is increased, which is the closest to the characteristics of water in human cells. Therefore, the water is easily absorbed through the cell membrane and absorbed by the human body. It is worth noting that it is not advisable to boil water with aluminum kettle, or excessive intake of aluminum ions will affect the baby's bones and nerve development; drinking fountains are likely to cause secondary pollution and should not be used.
