Long-term drinking of purified water requires supplementation of minerals

As a daily necessities of the human body, water is closely related to people's daily life

In April this year, the Chinese Nutrition Society released a new version of the "Dietary Guidelines for Chinese Residents (2022)".

When the importance of scientific drinking water has received so much attention, recently, the water science forum with the theme of "water health for a lifetime" organized by China Good Nutrition was held in Beijing.

Long-term drinking of purified water is not recommended

There are many scenes of daily drinking water, so the types of drinking water involved are also varied.

In response to this confusion, Zhang Na, an associate researcher at the School of Public Health of Peking University, said at the forum that according to China's "General Principles of Beverages", packaged drinking water includes drinking natural mineral water and drinking pure water, but they have certain differences

"Most of the mineral elements in drinking pure water have been purified and removed, and mineral water contains a certain amount of mineral elements

Drinking water for calcium is meaningful

It is worth noting that the theory of "water is a nutrient" has also been re-mentioned in this forum

Ma Guansheng, a professor at the School of Public Health of Peking University, said that the previous textbooks did not justify the name of water until the second edition of the "Encyclopedia of Chinese Nutrition Science" confirmed that water is a nutrient and the one that the human body needs the most

At the same time, Ma Aiguo, executive vice chairman of the Chinese Nutrition Society and professor at the Institute of Nutrition and Health of Qingdao University, believes that several minerals in water are beneficial

In addition, in Ma Guansheng's view, if the calcium content in the water is high, then this water can be used as one of the sources of calcium

Zhang Na believes that diet is the most important way to supplement elements, but under the premise that the intake of calcium elements in our country is lacking, it is also possible to appropriately supplement some mineral elements through drinking water

Mineral supplementation is essential

Among the recommended amounts in the Dietary Guidelines for Chinese Residents (2022), adults with low levels of physical activity should drink 1500-1700 ml of water per day

"For people who have been drinking pure water, they should pay attention to the supplementation of minerals in food

Finally, Ma Aiguo said that scientific drinking water is related to everyone's health, and correct understanding of water health is the nutritional knowledge that everyone needs to master
