What kind of water should I use for milk powder?
Recently, some media have stated that mineral water cannot be used to formulate infant formula because the minerals contained in mineral water are directed at adults. If the infant is consumed in large quantities for a long time, it will increase the burden on the kidneys, and may also cause indigestion, loss of appetite and constipation. And other issues. Does mineral water really harm baby's health? What kind of water should you use to flush baby milk?
Water for milk powder is more important for babies
First of all, we have to distinguish infants of different ages. For infants and young children over six months old, although some of their organs have not yet fully matured, they are not as fragile. Moreover, this age has begun to eat complementary foods, whether it is breast milk, formula milk powder or complementary foods, the content of nutrients in them is not fixed, but changes within a certain range, the baby itself has various mineral content changes in food A certain tolerance range. Therefore, as long as the drinking water is qualified for sanitary conditions and the mineral content is too high, generally infants can be flushed with milk, and drinking of bitter mineral water with high mineral content can be avoided. (For bitter mineral water, please read: Bitter mineral water can drink?)
For infants within six months, milk is the only source of nutrition. Whether it is breastfeeding or formula feeding, no extra water is needed under normal circumstances. At this time, the water used to flush milk powder is relatively important. Therefore, the following content is also mainly for babies under six months.
What water is used to flush milk powder, how does it say abroad?
The question of what water is used to flush milk powder is not just what Chinese parents want to know. Parents abroad have the same question. In 2005, the European Food Safety Authority issued a health recommendation on how to formulate powdered milk. One of them is about how to choose to call water. Taking into account the health conditions of the European Union’s drinking water, they believe that it is not necessary to boil water. For reconstitution of formula at home, it is recommended that tap water be used if tap water content can meet the relevant standards for bottled water for infants. At the same time, it is also necessary to pay attention to the flow of water for a few seconds before turning on the tap, and use only cold water. Do not use the water in the hot water pipe. The water temperature in the water pipe exceeding 25 degrees Celsius may increase the content of microorganisms and minerals in the water. In addition, the faucets and the surrounding environment should be cleaned regularly. It is not advisable to use tap water filtered by a water filter or other domestic water filtration device, as this may cause microbiological contamination in the water.
If these requirements cannot be met, the European Food Safety Authority recommends using bottled water to flush milk powder. Bottled natural mineral water or spring water suitable for babies can be used. When there is no suitable drinking water or bottled water is available, consider using boiled water after cooling.
So, what indicators are needed for bottled water for babies? The French Food Safety and Health Administration issued relevant key indicators in 2003. In order to qualify for baby use, a bottled water must satisfy a range of indicators ranging from mineral content, heavy metal content to microbial indicators and even packaging materials, in addition to satisfying the drinking water hygiene standards. For example, the required (but not all) sulfate content does not exceed 140 mg/l, the calcium content does not exceed 100 mg/l, the magnesium content does not exceed 50 mg/l, and the fluorine content does not exceed 0.5 mg/l. At the same time, the French Food Hygiene and Safety Administration also considers it necessary to remind consumers that long-term heavy use of tap water with a sulfate content of more than 140 mg/l and a fluorine content of more than 0.5 mg/l poses risks to the health of infants.
Of course, there are different voices. For example, the British National Health Service (NHS) recommends on its website that unless local water sources are contaminated or travel abroad and local water sources are not suitable for drinking, bottled water should not be used because bottled water is not sterilized and sodium and sulphate levels may be exceeded. many. They suggest that if bottled water is to be used, care should be taken that the sodium content is less than 200 mg/l and the sulfate content does not exceed 250 mg/l. And whether you use bottled water or tap water, boil your water at least 70 degrees Celsius or more.
How to choose the specific situation in China?
As for the domestic situation, we may wish to first look at what kind of national standards each of these types of water follows. The tap water that everybody says, that is to say drinking water, the corresponding national standard is GB5749-2006, which mainly defines some microbes, heavy metals, and some minerals and other indicators. The standard states that the total soluble solids content should not exceed 1000 mg/l and sulfate should not exceed 250 mg/l. Drinking pure water in bottles or drums requires drinking water that meets drinking water standards as the raw material, which is obtained through appropriate methods to remove other substances. It can be considered as water that contains almost no other minerals, and its corresponding national standard It is GB17324-2003. The mineral water that everybody drinks usually needs to meet the national standard of drinking natural mineral water GB8537-2008. Mineral water does not need to meet the limits of drinking water on mineral content, and the mineral content of different mineral waters may vary greatly.
Taking into account China's vast territory, the difference in water quality in various parts of the country may be relatively large. It is therefore difficult to generalize whether tap water is suitable for flushing milk powder. If the water quality of the local tap water is relatively hard and contains more minerals, individuals cannot know the content of specific minerals. I am afraid that bottled water is more appropriate. If you want to use tap water, be sure to burn it before using it.
If you want to use bottled water, you can choose according to the mineral content marked on the specific product label. For example, a combination of French and British standards can be used, with sulfates not exceeding 140 mg/L, calcium levels not exceeding 100 mg/L, magnesium levels not exceeding 50 mg/L, fluorine levels not exceeding 0.5 mg/L, and low sodium levels. At 200 mg/L, the brand's qualified products will not affect the baby's health.
In addition to excessive minerals, some parents are concerned about the lack of minerals in purified water, which is detrimental to the health of babies. In fact, this does not need to worry about. Infant formula itself already contains enough nutrients to meet the needs of the baby, and minerals are no exception. Therefore, the use of qualified pure water to flush milk powder is also completely possible, and will not cause malnutrition in infants.
As for the kind of self-filtered water in the community, or the vat water that is not clearly identified in the community, it is best not to flush infant milk powder for safety reasons. If you want to use it, you must boil it.
