" iodized salt is caused a disease and said " Lack scientific basis
Ministry of Public Health provides " expert's advisory opinion " and responds the query - -" iodized salt is caused a disease and said " Lack scientific basis
According to " health newspaper ", a few days ago, medias reported, the clinicians of the domestic many areas, especially coastal areas reflected thyroid gland disease had illness coming on and was on the rise, and excessive to eat, it adds iodized salt to be arch-criminal one of. As to this, Ministry of Public Health provides expert's advisory opinion to respond recently: Thyroid gland disease itself have illness coming on mechanism to be complicated, influence factor more, about querying especially in the media the intersection of women and the intersection of thyroid gland and the intersection of cancer and morbidity increase with the salt adding the relation between the iodine, lack the effective evidence of making people subdue.
Thyroid gland disease takes place high
It is not objective to impute to iodized salt
In recent years, in the whole country, especially coastal area, the salt adds the iodine policy to receive increasingly manily to query. Tianjin, Liaoning, Shanghai, Zhejiang and other places, many medical investigations indicate the disease morbidity of thyroid gland is increasing notably every year, and it is excessive to take in the iodine and is considered as an important factor. As to this, the advisory opinion of the expert that Ministry of Public Health offers emphasizes, in recent years, domestic some area thyroid gland diseases really have a high tendency that take place, but because salt add iodine is not objective its.
Up until now, the scientist does not have clear pathogenic factor and mechanism to thyroid gland cancer and relevant thyroid gland disease, the exposing dosage and time, eating habit, life style, spirit and inherent cause etc. of it and environmental factor, pollutant, carcinogen has a certain connection. Take thyroid gland cancer as examples, besides inducements such as spiritual pressure, infecting, overworking, wound,etc., do not exclude from nature, social environment and change, pollute the influence brought either.
Expert advisory opinion point out for crowd that iodine nutrition is normal, salt add iodine can exert an influence on the disease table of thyroid gland; And for that the iodine lack crowds, causing first overbearing morbidity of iodine will increase after the salt adds the iodine, but just crossing one.
Do not " lack the iodine when eating the marine product "
Statement incorrect
The marine product in the coastal area is supplied abundantly, residents can obtain enough iodine nutrition from the marine product, add the iodine in the salt? If take the salt to add the iodine measure, will cause the iodine excessively? Expert's advisory opinion provides the answer to this. Since 1994, the Ministry of Health revealed to the iodine nutritional status investigation of the crowd of Shanghai, Zhejiang, Fujian, Hainan and other places, the iodine amount obtained through the daily diet, can't meet organism's needs. Residents of coastal area have a public health problem of iodine athrepsia at various degrees too. Especially Hainan Province, nearly half the children have malnutritive iodine, because lack the iodine to lead to the fact nearly ten percent of the children have situation of low IQ.
Crowd iodine nutrition level of our country
It is suitable overall
Expert's advisory opinion thinks, the crowd iodine nutrition level of our country is in suitable state overall at present, but it is still very serious to prevent and cure the iodine deficiency task. Our country lack the intersection of iodine and area have 5% - 10% population fail to eat qualified iodized salt still, Tibet and Hainan are in iodine to lack the state wholly. In 2007, World Health Organization thinks China is nearly 121 every year. 90,000 neonates are not protected by iodine.
The salt adds the iodine amount
Really reduce the leeway
Expert's advisory opinion thinks, according to recent monitoring. All in all, the iodine nutritional status of our country is in can accept competence, but the iodine content is slightly a bit high in the salt. For this reason, the expert of Ministry of Public Health forms the proposal on adjustments: It is 30 mg/kg that the mean value of adding the iodine amount is reduce by current 35 mg/kged. If this mean value is not still fit for some provinces (district, city) Actual conditions,can adjust appropriately. At present, this opinion is being applied to be reported for approval according to the procedure.
