It depends.

Your need for iodized vs non iodized salt will depend on what is causing your thyroid gland to be unable to produce hormone.

甲低引起的原因有:

1.缺乏碘: 如odine deficiency或goiter (90% cases of goiter are caused by odine deficiency,a lack of iodine in the diet.),那么你得补碘盐.

2.先天性甲状腺缺乏症( Congenital hypothyroidism ):占0.2%.你得吃levothyroxine,吃不吃碘盐无关紧要.

3.甲状腺被切除: 没了甲状腺了,你得吃levothyroxine,吃不吃碘盐无关紧要.

4.甲状腺功能问题或是被诊断为Hashimoto's thyroiditis(一种autoimmune disease),都是甲状腺本身不能产生足够的甲状腺荷尔蒙,光靠补碘盐没用,得吃levothyroxine.

总之,孩子/孕妇/甲状腺功能正常的人得补碘盐,这是防止甲低的有效饮食方法.
