14th CNSC Sub-Forum - The 14th National Conference on Nutritional Science Water Nutrition and Health Forum was held, water nutrients, infant and young children drinking water and other issues caused academic concern.

the morning of September 22, 2019, the 14th National Conference on Nutrition Science, The International Forum on Drinking Water Nutrition and Health was held at the Nanjing International Expo Conference Center. Hosted by the Chinese Nutrition Society, the forum shared new progress, achievements and practices in the field of drinking water nutrition and health at home and abroad with experts from domestic and foreign research institutions, disease control institutions and universities.
Participants in the Water Nutrition and Health Forum
This forum, experts from all walks of life discussed hot topics such as nutrients in drinking water, hydration status and health, drinking water characteristics of infants and young children, and standard regulations.
China should pay special attention to the importance of nutrients in water
the forum was chaired by Professor Ge Coyou, Honorary President of the Chinese Nutrition Society, Vice President of the Chinese Nutrition Society, and Professor Ma Guansheng of the School of Public Health of Peking University.
Professor Ma Guansheng said
on nutrients in water was the focus of the forum. Professor Ma first stressed the importance of drinking water. Professor Ma Guansheng pointed out that water is an important part of the human body, drinking water is closely related to human health, first of all, should advocate residents to drink enough water.
Zhang Na
"China's concern for drinking water safety is far greater than the concern for drinking water nutrition, water nutrition has not been the right attention." Dr. Zhang Na, from Peking University, said as he shared a report entitled "Nutrients in Drinking Water" at the forum. Calcium, sodium, potassium, chlorine, magnesium, iron, zinc, copper, chromium, iodine, cobalt, vanadium and selenium are essential elements for human health, while drinking water contributes between 1% and 20% to mineral intake, Dr. Zhang said in the report. In addition, who studies have shown that "minerals in water can partially supplement the intake of dietary minerals, especially calcium and magnesium, and may protect human health from cardiovascular disease, while removing minerals from water may pose a health risk". At the end of the report, Dr. Zhang Na suggested that in the future, when developing drinking water-related standards, policies and publicity, the role of nutrients in water should be fully taken into account and a comprehensive assessment should be carried out.
Shu weiqun
Professor Shu Weiqun of the Third Military Medical University put forward similar views in the report "Healthy drinking water, the important composition of Chinese children's balanced diet". In view of the current situation of a large number of reverse osmosis water purification process popular, Professor Shu Group pointed out that drinking water should choose water with a certain mineral content, not recommended long-term drinking "reverse osmosis membrane" process treated water. If you have to choose "excessive purification of water", we need to pay attention to mineral supplementation, reasonable diet, so that the body's mineral balance.
Junnan Wang
Professor Junnan Wang, a member of the World Health Organization (WHO) Water Quality Guidelines Expert Group at the National University of Singapore, highlighted the health risks of long-term consumption of pure water free of minerals. In his report Minerals in Drinking Water: Ingredients in Different Parts of the World and Their Potential Health Implications, he said prolonged drinking of purified water was associated with the occurrence of cardiovascular disease and cancer, while studies in India and Taiwan have shown that regular consumption of water with higher hardness can help reduce the incidence of these conditions. Magnesium and calcium in drinking water play an important positive role in coronary heart disease and bone metabolism, and with age, people should pay attention to the intake of calcium and magnesium in drinking water.
Brandi
Brandi, from the University of Florence in Italy, combined her team's research to highlight the importance of calcium and magnesium ions in drinking water from the perspective of mineral human absorption. She believes that calcium ions in drinking water have higher bioavailableness. The absorption efficiency of calcium ions is only 29.8%, while the absorption rate of calcium ions can reach 47.5% by drinking water. Calcium ions in drinking water can even partially replace milk for calcium supplementation.
nutrition experts at home and abroad pay great attention to the drinking
drinking water for infants and young children is another key topic of this forum. Infants and young children's body water content accounted for more than 75% of the body weight, in terms of weight, infants and young children drinking water is 2.5 times that of adults, drinking water mineral content will greatly affect the intake of trace elements and minerals in infants and young children. Therefore, water is more important for the life and health of infants and young children. Professor Hartemann of the University of Lorraine in France and researcher He Mei of the Beijing Institute of Nutritional Sources have reported on this issue.
Hartemann is
. Professor Hartemann's team is a global leader in drinking water for infants and young children and a standard-seter for drinking water for infants and young children in France. Professor Hartemann, in his report "Water quality of drinking water for infants and young children and nutrition in water at all stages of the human body", argues that drinking water is one of the indispensable channels for infants and young children to supplement trace elements, and that infants and young children should pay attention to the ratio of mineral elements in drinking water to avoid geographical effects on the level of intake of trace elements in the human body. Professor Hartemann also shared the relevant laws and regulations on drinking water in France, which are useful for the improvement of relevant domestic regulations.
Hemei Researcher,
He Mei Researcher, made a report on "An Overview of Drinking Water Regulations for Infants and Young Children at Home and Abroad". She points out that in addition to giving your baby drinking water, the water used to soak milk powder can also affect your baby's mineral intake. For example, she says, infants and young children consume twice as much sodium as infant water (sodium≤20 mg/L) when formula is formulated according to tap water standard (sodium ≤200 mg/L). Their team's research found that sodium levels in some mineral water and tap water in some areas can lead to high sodium intake in infants. Too much sodium can affect a baby's kidney health.
, the effects of bacterial problems in drinking water on the baby's immune system cannot be ignored. FDA regulations state that water given to infants and young children is not commercially sterilized and needs to be labeled "unsterilized".
the drinking water for infants and young children should have more stringent standards, so many countries now have drinking water for infants and young children, the market is more mature. The United Kingdom, France, the United States, Austria and other countries have introduced drinking water-related standards for infants and young children. In addition to infant food should have commercial sterile related standards and regulations, China has not put forward special requirements for drinking water suitable for infants and young children, relevant research and standards need urgent attention.
experts to promote
of drinking water and human health-related research, and promote the improvement of relevant standards and regulations is of great significance.
