National policy of universal iodine supplementation

1994 65438+ 10 1 Regulations on the Administration of Iodine Deficiency Disorders Salt came into effect. Under the background of the national iodine supplementation campaign, the health of 500 million people with adequate iodine has been completely ignored. Big cities and coastal areas belong to mild iodine deficiency areas, and there are more protein and iodine-rich foods in the population's diet structure than in other areas, so there is room for reducing the concentration of iodized salt for the whole people.

In fact, the research team led by Teng Weiping, the former president of China Medical University, started the five-year project "The Influence of Iodine Intake on Thyroid Diseases" from 1999, and the conclusion shows that iodine deficiency and iodine enrichment will lead to thyroid diseases. During the "two sessions" in 2002, Professor Teng Weiping, then a deputy to the National People's Congress, took the lead in proposing a proposal to amend the National Salt Iodization Regulations. The proposal has been highly valued by the state, and the relevant departments have revised the national standard of iodized salt in time, lowering the lower limit standard of iodine content in table salt. In the same year, on the Day of Prevention and Treatment of Iodine Deficiency Disorders, the state put forward a new policy of "adjusting measures to local conditions, guiding by classification, and scientifically supplementing iodine".

Cui, a professor at Zhejiang University School of Medicine, said that a report by the Nutrition Society of China showed that the average daily salt intake of urban residents in China was 1 1g, while that of rural residents reached 17g. This means that according to the calculation that most iodized salt in the market contains 20-50 micrograms of iodine per gram of salt, the daily iodine intake of China people has reached an astonishing 220-850 micrograms, far exceeding the safety line of 200 micrograms per day set by the World Health Organization.

In May 2009, the Ministry of Health held an emergency meeting on the issue of iodized salt, and decided to conduct a general survey of iodine nutrition status of residents in coastal areas of Zhejiang, Fujian, Liaoning and Shanghai. The policy put forward by the census is "scientific iodine supplementation and classified guidance". Yang Yuexin, deputy secretary general of China Nutrition Society, explained that "classification guidance" means that the iodized salt should be adjusted to local conditions.
