It initiates the pathogenic misgivings clouding mind that the salt adds the iodine The expert appeals for stopping forcing iodized salt
"Big city and the intersection of coastal area and itself belong to, lack the intersection of iodine and area slightly, crowd meal protein and rich the intersection of iodine and food other district large relatively in the structure, the whole crowd's salt has leeway to reduce to add the iodine density. "
Policy implement will it be long a today 15 year, medias report in enrich the iodine by the whole people, the clinicians of some areas reflect thyroid gland disease has illness coming on and is on the rise, then some experts call upon, stop carrying on adding the iodine to the salt by force of the country, should decide whether should add the iodine according to the actual conditions of different areas.The iodine is a kind of indispensable microelements in the human body. Lack the iodine, will lead to the fact hormone of thyroid gland is formated and secreted or the physiological effect is insufficient, cause the thyroid gland to be swelling.
China's disease accuses of infectious disease in the centre national iodine deficiency consults plain researcher Mei Li in the laboratory and tells " scientific and technological newspaper of Beijing ", in 60~80 times last century, it verified, 31 provinces and cities in the whole country generally lacked the area for the environmental iodine outside that our country investigated. Including Shanghai, because meal nutrient is remedied, has not formed iodine deficiency prevailingly, but people are in the state of slight iodine athrepsia.
At that time, Association for the Handicapped estimate, lack intelligence that iodine cause, bow crowd, account for the intersection of intelligence and disabled 80% of crowd, but this is only the iceberg corner. The iodine lacks intelligence and physical stamina caused to lose, it is more serious consequence. According to our country's relevant data, the goiter prevailing area, children's IQ not so prevailing than district is lower by 10%~15%. It is obvious, iodine deficiency is a public health problem influencing the national health quality and social economic development of our country seriously.
Then, the country began to propose " all edible salt adds the iodine " in 1994 (USI) Action,this day edible last salt, animal feeds edible to add by salt wanting to last iodine salt, food industry often family.
Since it is so, why is after iodine mended for 15 years, will peak period when thyroid gland disease has illness coming on appear again?
Chief physician of Chaoyang hospital division of endocrinology Li Jing tells " scientific and technological newspaper of Beijing ", in the past few years, the thyroid gland patient of every large hospital of the whole country presented the phenomenon of increasing gradually. Cause reason of phenomenon this very complicated, and excessive to eat, it adds iodized salt to be reason one of.
The Fujian researchers of subsidiary Peking Union Medical College Hospital of medical university have carried on an investigation for 10. They find, generally eat with iodized salt, the thyroid gland function is hyperfunction (are abbreviate as first overbearing) If you can't lead, know by increase. As to this, thyroid gland disease specialized department attending physician Zhang ZhenE of institute of traditional Chinese medicine in Hubei tells " scientific and technological newspaper of Beijing ", there is too much uptake amount of iodized salt, will cause first overbearing or the thyroid gland is swelling; First overbearing patient will be relatively excited and wanting to have a meal, but people relatively become thin, have palpitation, weak, can cause diseases such as heart disease,etc. for a long time.
Li SuMei says, in " all edible salt add the iodine " Before this, coastal area and big city of our country are mostly that the other environment lack the iodine area. In 1994, researchers launched the iodine nutrition survey in ten major cities of Beijing, Shanghai, Wuhan, Jinan, Shenyang, Fuzhou, Xi'an, Zhengzhou, Hefei, Harbin. The result reveals, besides some areas of Wuhan, Xi'an, Beijing, the average urine iodine levels of children in the other areas are in lacking iodine or borderline normal value lower limit.
Society's Deputy Secretary-general of China's nutrition, nutrition and food security, Center for Disease Prevention and Control of China, chief of the office of food evaluation of nutrition researcher Yang YueXin tell " scientific and technological newspaper of Beijing ", as to human body, the intersection of iodine and at the state that 100~200 micrograms are most suitable level in the each urine. Under being in this state, iodine deficiency and high the intersection of iodine and morbidity of disease the lowest. If higher than 300 micrograms liter, is considered to take a photograph of the iodine excessively.
" World Health Organization (WHO) The intaking amount of daily iodine of adult recommending it is 150- 300 micrograms. At present, national iodized salt monitors the result, the average iodine content of iodized salt is 30 mg/kg. Take in 5-10 grams of salt, calculate according to every day each person, the iodine quantity of taking a photograph of every day is about 150- 300 micrograms. Deduct the losses of cooking and human supersession, the intaking amount of the iodine will not be higher than the recommendation amount of World Health Organization. " SuMei Li say European Union and the intersection of U.S.A. and medical research institute study, verify people to iodine can the intersection of tolerance and upper limit reach 600- 1100 microgram per day. So, it is safe that the salt adds the iodine amount.
" all edible salt add the iodine " After implementing, in 2003, researchers were in the city of 11 provinces such as Beijing, Tianjin, Shanghai, Dalian, Guangdong, have carried on the investigation to school-ager, women of child-bearing age, pregnant woman, women breast-feeding their children, infant and pre-school children iodine nutrition again. These 5 crowds' iodine nutrition is basically suitable.
Li SuMei thinks, in big city and coastal area, the excessive problem of iodine does not exist. High reason that take place complete because salt add iodine is not either objective the intersection of thyroid gland and disease. Because the main inducement of first overbearing and relevant thyroid gland disease, also include spiritual pressure, infecting, overworking, wound,etc., do not get rid of the influence that nature, social environment change, pollute etc. to come to the high headband of of thyroid gland. At present, some tumour morbidity independent of iodine is on the rise too, this proves this from another side.
