There are two different views on whether children can drink pure water often. One view is that because purified water removes most minerals, drinking purified water for a long time will cause the lack of minerals in the body; Another view is that the human body can obtain minerals from various sources, such as food and drink, and food is the main source of minerals. Because pure water is a new product in recent years, so far, there is not enough scientific evidence to explain what kind of impact it has on health after long-term drinking. There are many kinds of mineral water. Due to different producing areas, different kinds of mineral water contain different minerals, some are rich in strontium, some are rich in zinc, iodine, lithium, selenium and so on. Therefore, not all mineral water is suitable for children to drink as drinking water for a long time.
At present, water consumption is very blind. Pure water and mineral water are not equal to healthy water. Pure water and mineral water should not be used as children's leading drinks. Nowadays, advertisements for various drinks are endless. More and more children are thirsty and want to drink, but fewer and fewer people drink boiled water. This is a bad tendency that affects children's growth. Nutritionists point out that from a nutritional point of view, any sugary drink or functional drink is not as good for health as boiled water. Pure boiled water is the easiest way to quench your thirst. It can be metabolized immediately after entering the human body, and has the functions of regulating body temperature, transporting nutrition and cleaning the body. Therefore, relevant experts call for the promotion of "drinking boiled water campaign". They found that naturally cooled cold water after boiling is the easiest way to promote metabolism through cell membrane, increase hemoglobin content in blood, enhance immune function and improve human disease resistance. People who are used to drinking cold boiled water have high dehydrogenase activity in their bodies and less lactic acid accumulation in their muscles, so they are not easy to get tired. The survey data shows that children's weight is developing at two poles, either too fat or too thin. It is said that drinking too many drinks is one of the important factors. Children who have a big appetite and drink a lot of drinks are obese because of excessive calorie intake. Some children with poor appetite are thin because drinking drinks affects eating and their calorie intake is insufficient. In addition, there are many side effects caused by a large number of nourishing drinks. The harm of artificial pigments in beverages can not be ignored. Excessive accumulation of pigments in the body will interfere with the functions of many enzymes and have an impact on metabolism and children's growth and development. Pigment adheres to the child's tender digestive tract mucosa, which is easy to cause indigestion. In addition, too much pigment is also one of the factors leading to ADHD in children.
