BEIJING, July 27 (Xinhuanet) -- The Ministry of Health is considering lowering the level of iodine in table salt, despite an earlier statement that the level was appropriate for the majority of the population.
A new iodine level of 20 to 30mg/kg is suggested in a proposed revision of the iodine content standard publicized by the ministry on Monday to solicit public opinion.
The currently acceptable amount of iodine in table salt is 20 to 60 mg/kg, according to the ministry.
The proposed standard also authorizes provincial level governments to increase or decrease the content by up to 30 percent, depending on local dietary requirements.
With the margin, the top level of iodine could reach 39mg/kg and the lowest 14mg/kg.
Details of the proposed change are available on the ministry's website, which is seeking public input on the issue until September 12.
"People in different regions consume different amounts of salt, so it's impractical to look for a unified standard of benefit to all," said Chen Zupei, a senior researcher at the Ministry of Health, who participated in drafting the new standard.
The ministry also said on Monday that although the current level of iodine is acceptable to the majority of the population, residents in five out of China's 34 provinces, autonomous regions and municipalities consume an excessive amount of iodine from table salt, while those in 16 other provinces consume more than is considered healthy.
Chen said the regions that consume an excessive amount of iodine are not in coastal areas where more seafood is readily available.
