Pathogenicity of iodized salt of suspicion

"Iodized salt is a harmful thing!" 72 years of Zhejiang University School of Medicine Professor Cui Gonghao said angrily. In 2008, Cui Gonghao in physical examination, the wife of strange found a thyroid cyst. Cui Gonghao couples always attaches great importance to food security, in the immediate family members do not have the relevant history. Thyroid cyst is how it happened? Cui Gonghao am very puzzled. Cui Gonghao survey that: since 2000, sharp increase in thyroid patients in Zhejiang Province, particularly in Hangzhou, Ningbo, Zhoushan coastal areas for the residents of many. In China, for a time was one of the most severe iodine deficiency in the world, has a population of more than 700 million more iodine deficiency. In 1994, universal consumption of iodized salt, as enforcement of a national policy in China. However, iodine supplementation for all policies implemented today, after 15 years, more and more local epidemiological surveys, in some areas, especially coastal areas is to usher in peak of thyroid disease. Salt iodization policy questioned by more and more. What led to the frequent occurrence of thyroid disease? iodized salt is associated with thyroid disease how? disease control Department of the Ministry of health and has not been concluded on the subject. "This cannot be accidental one-time event. "Cui Gonghao believes that suspects the biggest" murderer "is the daily consumption of iodized salt. Thyroid is the largest endocrine glands of the body. Inorganic compounds of iodine in food, with gastrointestinal absorption into the blood circulation, rapidly concentrated for thyroid uptake. After iodide into the cells after function oxidase, producing activity of iodine, formed after the thyroid in combination with other substances, then secreted into the blood circulation. If there is no involvement of iodine, not normal secretion of thyroid hormones, endocrine system, reproductive system and the digestive system of the body runs will be affected. "Just like a plant, iodine is a catalyst in the production process, without it, production is down. "Cui Gonghao says," but if too many catalysts, physiological responses will also interfere with the original, as bad consequences. "According to a report of the Chinese nutrition society: average daily salt intake to 11 grams of Chinese urban residents, reached 17 grams of rural residents. "This means that, in accordance with the currently available iodine salt salt iodine-containing 20~50 μg per gram calculation, the Chinese 220-850 micrograms daily iodine intake at an impressive, far exceeded the World Health Organization designated security lines of 200 μg/day. "Cui Gonghao statistics derived from this amazing figures. Cui Gonghao is difficult to accept that, he in the Hangzhou normal supermarket and shops are simply not buy non-iodized salt. An iodized salt region provinces is not iodized salt cannot be legitimate channels of circulation, or is deemed "private salt". Cui Gonghao repeatedly call salt industry company in Zhejiang Province, they told him: iodine supplementation is the basic national policy, if you must buy non-iodized salt, salt products can go to the salt industry company stores, but it must be based on proof of hospital invoice-related diseases. "This I find it difficult to accept, such a premise is, unless you first got sick, and prove to them, you can not eat iodized salt. "Cui Gonghao said. During the national people's Congress held this year, Zhejiang submitted on behalf of Lu Yi-Yu: "excessive importance to supplying iodine salt problem in case the event once again similar to sanlu milk powder as food safety. "May this year, the Ministry of health emergency meeting decided in Zhejiang, Fujian, Liaoning, Shanghai with four" iodine nutritional status of residents in coastal areas "census. Experts believe that if the survey is able to support salt iodization of too many conclusions, policies are likely to face adjustment of iodized salt. (据《南都周刊》 陈鸣 许十文 单崇山／文)
