    China Consumer News The National Health and Health Commission recently issued a recommended health industry standard, "Iodine deficiency areas and iodine-appropriate areas of the delimitation."
    according to the standard, the standard water iodine median boundary value of the iodine-appropriate area is set at 40 to 100 micrograms/L, and uniodized salt can be supplied.
    the standard will come into effect on 1 July 2020.
    is a necessary micronutrient, the intake of human iodine should be within a certain range, too low or too high will have adverse effects on the body.
    China was once one of the countries with a serious epidemic of iodine deficiency disease, most of the external environment iodine deficiency (iodine deficiency disease area water iodine content of 10 micrograms / liter), through salt iodization prevention and control strategy, by the end of 2015, 94.2% of the counties in the country achieved the goal of eliminating iodine deficiency disease.
    In recent years, however, the incidence of thyroid diseases such as thyroid nods has been increasing, and many people have doubts about whether to continue to consume iodized salt, which also puts forward higher requirements for the prevention and treatment of iodine deficiency diseases in China.
    Shen Hongmei, a researcher at the Center for Local Disease Control of the China Center for Disease Control and Prevention, said: "The results of the 2017 national survey of iodine content in drinking water for drinking water show that 83.6 percent of townships with water iodine content below 10 micrograms per liter, 13.8 percent of rural areas between 10 and 100 micrograms per liter, and 2.6 percent of townships with water iodine content below 10 micrograms per liter."
    water iodine between 10 to 100 mg/L of the region needs to supplement iodine, where the water iodine range in which area belongs to the 'iodine-appropriate' area, has become an urgent problem before us.
    " iodine-appropriate areas refer to areas in the natural environment that can meet the normal iodine needs of the human body through drinking water and food intake without iodine supplementation measures.
    Shen Hongmei said that the standard adopted a combination of special investigation, past data analysis, literature review and calculation methods, put forward the division of iodine deficiency areas and iodine-appropriate areas of the water iodine boundary values.
    The median boundary value of standard water iodine in iodine-appropriate areas is set at 40 to 100 micrograms/L (in administrative villages, containing 40 micrograms/L and 100 micrograms/L);
    In addition, according to international organizations and current domestic standards, the standard median urine iodine limit for children aged 8 to 10 years is 100 micrograms /to 300 micrograms/L (excluding), the thyroid swelling rate limit for children aged 8 to 10 years is 5%, and the median urine iodine for children aged 8 to 10 years is less than 100 micrograms per liter. The
    standard can be provided to health administrative departments and professional bodies at all levels for the designation of iodine-deficient and iodine-appropriate areas, and for scientific and effective prevention and control measures in accordance with the Regulations on the Management of Iodine Deficiency Prevention and Control of Salt Iodization.
    Iodized salt must be supplied in iodine-deficient areas and iodized salt or uniodized salt in iodized areas, depending on the surrounding area, but it is recommended that pregnant women continue to consume iodized salt in this particular group.
    ," Shen Hongmei told reporters.
    However, experts stressed that the standard is a comprehensive consideration of the iodine content of drinking water in different regions and the status of iodine nutrition in the population to establish a regional criteria, only to assess whether an area is iodine deficiency area or iodine-appropriate area, not applicable to the individual iodine nutrition in the region.
