Iodine deficiency is the most common preventable cause of mental deficiency. Remarkable success has been achieved by the use of iodised salt to correct this deficiency in many industrialised countries since 1920. The Government of India has adopted a strategy to iodise all edible salt in the country to overcome iodine deficiency. Universal salt iodisation is the principal public health measure for eliminating iodine deficiency disorders. Daily iodine intakes of up to 1000 micrograms, appear to be entirely safe. In India, the likelihood of exceeding this level is quite small. Iodised salt does not cause any side effects. Iodine in iodised salt does not carry risks for persons who are already iodine sufficient. iodisation of salt at the current level of fortification (15-30 ppm iodine) keeps intakes well within a safe daily range for all populations, irrespective of their iodine status.
碘缺乏是导致智力缺陷最常见的可预防原因。自1920年以来，许多工业化国家通过使用加碘盐来纠正这种缺乏，已取得显著成效。印度政府已采取一项战略，对该国所有食用盐进行碘化处理，以克服碘缺乏问题。全民食盐碘化是消除碘缺乏病的主要公共卫生措施。每日碘摄入量高达1000微克似乎完全安全。在印度，超过这一水平的可能性很小。加碘盐不会引起任何副作用。加碘盐中的碘对碘摄入已充足的人没有风险。按照目前的强化水平（碘含量为15 - 30 ppm）对盐进行碘化处理，可使所有人群的摄入量保持在安全的每日范围内，无论其碘状况如何。
