Baby water

Because infants and young children need minerals and their digestive systems are fragile, this baby water is characterized by "minerals, but not many".

However, at present, there is no standard for distinguishing infant water and adult water in China, and there is no unified identification index for infant water in the world, so whether this water is really more suitable for infants and young children to drink, there is no way to certify.

Weak alkaline water

Weakly alkaline water generally refers to drinking water with a pH of 7-8. Because pure water is neutral, and some natural sources of water contain some mineral components, it will appear weakly alkaline.

For this product, the slogan of the merchant is generally "the pH value is between 7-8, closer to the pH of the body". However, the pH of different tissues of the human body and different parts is different, and the human body itself has a strong self-balancing mechanism, so no matter how much water the pH is, drinking into the stomach is the same.

How should the water on the market be classified?

Mineral water (drinking natural mineral water):

Mineral water has two main characteristics, one is the water source, must be naturally gushing out from the depths of the ground or collected by drilling water, not only can not be polluted, but also the content of minerals, trace elements or other components must meet the national standard value. The second is processing. Mineral water can only be processed and filled at the source of the water, not processed off-site.

Purified water (drinking pure water):

The water source is generally tap water, which is then processed after the appropriate water purification process. Not only the pollutants and bacteria and viruses in the water have been removed, but even the minerals have been removed.

Other drinking water:

There are also two types of other drinking water, one is a natural source and the other is a public water supply system.

The first is drinking water processed from natural sources, allowing only a limited number of treatment methods without altering the basic physico-chemical characteristics of the water.

Another kind of drinking water with the public water supply system as the water source is generally artificially added magnesium and potassium ions in pure water to adjust the taste.

How many of these misconceptions about water do you know?

Overnight water can not be drunk:

Boiling water, if the lid is covered well, let alone overnight, put at room temperature for 3 days, the nitrite content inside is still within the national safety standard (1 mg / liter), and it will not cause cancer.

If you are accustomed to drinking water with the lid open, there may be mosquitoes, dust falling into danger, such water or do not drink.

Do not drink boiling water:

Studies have measured:

Tap water is heated 8 times repeatedly, and the nitrite is only about 1/300 of the national safety standard (1 mg/liter), and we drink one or two liters of water a day, which is difficult to reach the toxic dose (0.2 grams). So boiling water at home every day, no problem, rest assured to drink.

Yin and yang water can not be drunk:

First of all, clarify the concept of yin and yang water, add half of the boiling water to half of the cool water, and mix it into warm water, which is the yin and yang water. Yin and yang water can not be drunk, or to specifically analyze the specific situation, if the cold water is raw water (unblanched water), which may contain bacteria, viruses, parasites, etc., can not be drunk; on the contrary, if the cold water is cool and open, just because the temperature is different and mixed, then there is no problem, you can drink with confidence.

Mineral water powder is healthier:

Milk powder itself contains minerals, if you use more mineral-containing water to mix, the osmotic pressure of the milk powder will be very high ~ it will also affect the baby's kidneys.

Therefore, it is best to use pure water to make milk powder, do not worry about the lack of nutrients in the child, and the minerals in the milk powder/breast milk are enough.

In fact, no matter what kind of water, the water itself only has the effect of quenching thirst and replenishing water, minerals and trace elements are mainly obtained from food, so there is no need to pursue those "additional effects" too much when purchasing.

As long as it is a formal way, the water produced by regular manufacturers ensures that the water is completely boiled when boiling water at home, and there are no mosquitoes, dust, etc., and the effect is the same~
