Water accounts for a large proportion of the human body. The body water content of infants and young children is as high as 80%. When the human body functions, it will consume water. It needs a lot of water to maintain the balance of human body function. Infants and young children are active and active, and need to replenish water in time to avoid dehydration. Infants and young children have poor physical fitness and weak immunity. The standard for drinking water is higher than that for adults. How to choose healthy drinking water has become one of the important concerns of parents.
In recent years, there have been media and experts claiming that children drinking too much "pure" water will lead to the lack of trace elements and minerals in the body, such as decreased immunity and poor bone development, which is not conducive to the healthy growth of children, the most healthy way. It is the tap water after boiling and cooling. Can such a wide spread of influence between parents be able to stand firm in scientific terms?
Let us first look at the so-called healthy tap water. The corresponding national standard is GB5749-2006, which mainly defines some microbes, heavy metals, and some minerals. The standard stipulates that the total dissolved solids content should not exceed 100 mg / liter, and the sulphate should not exceed 250 mg / liter. In actual life, the TDS (soluble total solids) of tap water in most areas of China exceeds 100 mg / l, especially in the northern region, it is more than 300 mg / liter.
Compared with adults, the kidney metabolism function of infants and young children is not fully developed, and the water requirement per unit weight is about 2.5 times that of adults. If the content of the elements in the water is too high, it will increase the baby's kidney burden, and simply boiling the tap water will not reduce the hardness of the water.
Next, let's take a look at what the experts say is too "pure" water, including bottled water and bottled water. The National Environmental Work Promotion Association has tested bottled water in the top 10 best brands in the United States and found more than 200 pollutants, including bacteria and industrial chemicals. 45% of the bottled water in the market is not as advertised. From natural springs or pure water, it is actually purified water in the city or simply tap water. Dong Jinshi, executive vice president of the International Food Packaging Association, pointed out that the PET bottles used in bottled water often contain substances that may cause chronic poisoning in the human body, especially when the bottle is in a high temperature ring, or does not drink in time after opening, harmful substances will Infiltrated into the water, it is harmful to health. It is not recommended for infants and young children to drink bottled water too much.
The water purifier has a better function, that is, it can be used now to avoid secondary pollution, which is more fresh than bottled water and bottled water. There are also many types of water purifiers. Currently, the ultra-filter water purifiers and reverse osmosis water purifiers are popular in the market. Ultrafiltration water purifiers can retain proper amounts of minerals and trace elements, but ultrafiltration machines can not effectively remove heavy metals in water. However, the body's intake of multiple metals is carcinogenic, so reverse osmosis water purifiers are recommended in areas with serious water pollution. The reverse osmosis water purifier filters out pure water and is basically free of any impurities and minerals. Generally, the raw water is tap water. It does not contain much minerals. Compared with food, the mineral content in water is less, so it can be ignore.
The RO reverse osmosis water purifier independently developed by Kaiyuan uses the RO reverse osmosis membrane developed by the world famous brand Dow, which can effectively filter out harmful substances such as bacteria, residual chlorine and heavy metals in water, and reduce the hardness of water to a certain extent. The effluent is safe and healthy, especially for families with children, the elderly and pregnant women.
Through the above analysis, we can draw the following conclusions: 1. The viewpoint advocated by experts to drink tap water for infants and young children is not only wrong, but also causes harm to the child's body; 2. Infants and young children should implement more stringent standards for drinking water. Large brands and quality-assured water purification products are essential for the healthy growth of children.
