Promote and improve the water-saving system and explore ways to drink healthy water

The 2nd Drinking Water and Health Summit Forum, co-sponsored by the Drinking Water and Health Branch of the Chinese Nutrition Society and the School of Public Health of Peking University, was recently held
in Beijing.
The conference was held in a combination of online and offline format, focusing on topics such as drinking water health, drinking water standard system, drinking water behavior, and drinking water strategies for different groups of people, and discussed healthy drinking water
.

Ma Guansheng, chairman of the Drinking Water and Health Branch of the Chinese Nutrition Society and professor of the School of Public Health of Peking University, said that the conference aims to promote extensive academic exchanges and experience sharing in the field of water and health among researchers in different fields, share the theoretical knowledge and technical methods of drinking water, hydration status and health-related investigation and research with public health workers and researchers, further strengthen the exchange and cooperation between hospitals, scientific research institutes, disease control, universities and enterprises and the integration of industry, education and research, and promote the rapid development of water and health scientific research.
Form the integration
of drinking water and health-related disciplines, scientific research cooperation, talent training and social services.

Promote adequate drinking water Carry out research on drinking water health for different populations

Water is a necessary nutrient to maintain human life, and it is also an important part of 60%-70% of adult body weight, and plays a role
that cannot be ignored in the body's metabolism, body temperature regulation and other mechanisms.
At present, a significant proportion of Chinese residents still face the problem
of insufficient drinking water and dehydration.
Dehydration can lead to a decline in cognitive function and physical activity in the short term, and may increase the risk of chronic diseases such as urinary diseases and diabetes in the long term, and the risk of early kidney damage in children with insufficient water intake and dehydration is significantly higher than that of those
with suitable hydration status.

Ma Guansheng believes that maintaining the balance of water in the human body is called the hydration state
.
The hydration state has a regulatory mechanism, which will be affected
by the external environment, age, gender, physical condition, exercise status, diet and other factors.
The latest edition of the Dietary Guidelines for Chinese Residents (2022) fully illustrates the importance of
adequate drinking water.
Advocate scientific drinking water, drink enough water, take the initiative to drink water, a small amount of many times, drink a glass of water every morning and evening, drink a glass of water every two hours, a glass of water about 200 ml
.
The type of drinking is recommended to drink white water or light tea, drink less or no sugary drinks, and replace white water
with drinks.

Wang Jun, a researcher at the National Center for Food Safety Risk Assessment, introduced the regulatory standards
for packaged drinking water.
She pointed out that the product name of packaged drinking water should not be labeled "activated water", "small molecule group water", "functional water", "energy water" and other unscientific content
.
When adding food additives, it is necessary to mark the words "Add food additives to adjust taste" and other similar words near the product name
.

Experts and scholars in the field of public health and clinical medicine are conducting research on drinking water behavior and health effects in different populations and environments, accumulating research evidence, and adjusting the recommended drinking water values for special groups such as children, pregnant women, athletes and other special groups with higher dehydration and corresponding health risks, and carrying out drinking water and health-related science popularization work for the general population and special populations
.

Protect water resources and ensure the safety of drinking water

Water is an indispensable natural resource
for economic development.
In order to ensure the safety of drinking water for Chinese residents, regulatory authorities and scientific researchers strive to improve technical standards and operating specifications
for key links from water source, water production, water transportation, water storage to water use.

Sang Xuefeng, assistant director and professor-level senior engineer of the Institute of Water Resources of the Chinese Academy of Water Sciences, pointed out that water is the source of life, the key to production and the basis of ecology, and also has an important impact
on industrial production and agricultural production.
It is necessary to manage water resources according to the principle of "water conservation first, spatial balance, systematic governance, and two-handed efforts", improve the level of water quality testing and management in China, especially in rural areas, promote and improve the water-saving system, rationally allocate water resources, and adhere to the protection of ecological resources
.

The "Drinking Water Sanitation Standards" to be implemented in April next year puts forward strict requirements for drinking water standards from different dimensions, which is more in line with the current domestic water quality situation
.

Zhang Lan, a researcher at the Institute of Environment and Health of the Chinese Center for Disease Control and Prevention, said that the formulation of the new national standard content is more comprehensive, strict and authoritative
.
From the source to the faucet, each important link puts forward corresponding management requirements for the possible impact of water quality, strengthens the control of water quality senses and pays attention to new pollutants, and adheres to the principle of water quality evaluation in urban and rural areas
