It causes thyroid gland disease to increase to enrich the iodine excessively Ministry of Public Health responds the query
The coverage rate of iodized salt, weigh an area and dispel the important data of iodine deficiency. Nowadays, someone refuses iodized salt, and the expert proposes the iodine cause danger to people more. Should eat with iodized salt on earth, has become a big problem at one time.
In fact, deserve " enrich the iodine " The more important thing is to let everybody choose salt kind according to the needs of oneself, avoid enriching the iodine blindly, but not wait to adjust the salt and add the iodine amount passively. The related departments should launch salt knowledge, enrich the iodine extensively knowledge is propagated.

According to Xinhua News Agency recent, until " the whole people's salt add the iodine " some media Query, think " it is excessive to enrich the iodine " in some areas Lead to the fact thyroid gland disease including thyroid gland cancer increases. Ministry of Public Health disease accuse of the intersection of office and relevant person in charge and the intersection of China and disease accuse of the intersection of centre and national iodine deficiency consult Li SuMei, chief of the office of experiment, claim this statement lacks the effective evidence.
The expert points out, the crowd iodine nutrition level of our country is in suitable state at present, but the high water iodine problem exists in a few areas, our country will reduce the iodine content in the salt next year.
Not that the adding the iodine amount is reduced " Make it rigidly uniform "
It showed that national iodine deficiency monitored the result in 2005: It is necessary for appropriate little range to reduce the iodine content in the iodized salt. Since 2007, Ministry of Public Health organized relevant experts to prove many times, formed and adjusted the current salt to add the iodometric opinion tentatively, reporting to the standard professional committee of food additive and verifying according to the procedure at present, apply to report to the national standardized committee of China for approval subsequently. It is estimated, relevant adjustment schemes will be announced formally in the first half of 2010.
The main content adjusted this time is: Will add iodine quantity to reduce currently appropriately, the accuracy is higher, the density is more suitable; If the iodine content is not still fit for some provinces (district, city) Actual conditions,should by adjust, submit to national health authority for record, carry out. Suffer from the intersection of thyroid gland and disease or take in too much patient of iodine, supply and does not add the iodine salt to high the intersection of iodine and area and some while being unsuitable while being other.
Iodized salt will not cause thyroid gland cancer to occur frequently
Expert point out salt add iodine prevent and cure practical experience of the past one hundred years such as iodine deficiency and investigate, prove in such aspects as clinic, epidemiology still: Will not cause the morbidity of thyroid gland cancer to increase after crowd's iodine nutrition improvement.
The expert does not think pathogenic factor of cancer and mechanism are clear, the pathogenesis of thyroid gland cancer is indeterminate so far. So thyroid gland the intersection of cancer and morbidity increase with salt adding iodine have a certain inference of connection according to insufficient, lack the effective evidence of making people subdue.
Ministry of Public Health disease accuse of the intersection of office and relevant person in charge say traditional idea think coastal area it is abundant for marine product to supply with, do not need to take the salt to add the iodine measure. But the domestic and foreign census data verify, the crowd of coastal area has iodine athrepsia, for instance area of iodized salt such as Shanghai, Zhejiang Zhoushan with low edible rate, the trend insufficient in intaking amount that the iodine exists too.
