Every child is the treasure of the family, and health is the top priority for the whole family. Whether it is the nutritional combination of diet or the health requirements for drinking water, they are all decided after careful consideration by parents. Regarding healthy drinking water, it has become the focus of everyone's attention. In recent years, more and more families have installed water purification equipment , but do you know that if you drink pure water for a long time, it will affect the memory of teenagers!
Environmental Health Teaching and Research Department of the School of Military Prevention Medicine of San Military Medical University conducted an experiment to detect the impact of drinking pure water in the background of low-magnesium foods through the Morris water maze experimental method on the learning and memory ability of young people. This study included the mother and mother feeding normal dietary water, normal dietary pure water, low-magnesium dietary normal water, and low-magnesium dietary pure water. After the baby rats were weaned, they drank water and fed according to their parent group categories. Since the growth and development of pregnant mothers and fetus had higher demand for nutrients than other stages of the body, the animal model established in this study can better reflect the possible impact of drinking pure water on rats' learning and memory ability, neural behavior and development under normal and lack of food magnesium.
In the positioning navigation experiment, the escape latency of mice in the normal dietary and normal drinking water group in the early training period were shorter than those in the positive control group, the normal dietary and the low-magnesium dietary and pure water group (P005). In the late training period of each group (late 2d), the escape latency of each group tended to be stable. Although there was no statistically significant difference between the groups, the trend still existed.
In recent years, many popular science articles have adhered to the view that "there is no difference between various waters", which is also very recognized by readers. However, the Ministry of Education and Shanghai have issued documents that do not recommend primary and secondary school students to drink pure water. In 2013, Shanghai issued a document stipulating that primary and secondary school students should not use reverse osmosis water unless necessary. The pure water is purified by reverse osmosis and other methods. In May 2019, the Ministry of Education issued the industry standard "Technical Requirements and Equipment Specifications for Drinking Water Equipment for Membrane Treatment in Primary and Secondary Schools" (JY/T0593-2019). It is clear that (water treatment equipment for primary and secondary schools) uses ultrafiltration and nanofiltration filtration methods. Only areas with high risk of source water pollution can use reverse osmosis. When the source water quality meets the standards, it is replaced with nanofiltration or ultrafiltration for treatment.
Currently, the common pure water is reverse osmosis water. The process of preparing pure water by reverse osmosis technology can remove harmful substances in the water, and also filter out essential mineral elements in the human body. Long-term drinking of mineral-free water after overtreatment not only increases the risk of cardiovascular diseases in humans and animals, but also affects the memory of adolescents. Memory loss in adolescents is not a trivial matter. In mild cases, academic performance declines and they cannot get into a good school. In severe cases, they may cause neurasthenia and low immunity, which will affect their health.
Compared with pure water, drinking natural mineral water can greatly supplement potassium, calcium, sodium, magnesium and other nutrients, promote hematopoiesis, and also regulate the activity of central nervous system . In fact, it is not only for teenagers, but also for people with osteoporosis and are not suitable for drinking pure water for a long time. Therefore, it is more suitable for normal people to choose to drink water containing minerals and has a certain hardness.
