为了解我国居民碘营养状况的健康风险,今年以来,国家食品安全风险评估专家委员会从尿碘水平和膳食碘摄入量两个方面,系统评估了我国不同地区居民碘营养状况的潜在风险。评估结果表明:从人群尿碘水平和膳食碘摄入量两个方面评价,我国除高碘地区外,绝大多数地区居民的碘营养状况处于适宜和安全水平,沿海地区也不例外;食盐加碘并未造成我国居民的碘摄入过量;我国居民碘缺乏的健康风险大于碘过量的风险。因此,继续实施食盐加碘策略对于提高包括沿海地区在内的大部分地区居民的碘营养状况十分必要。
In order to understand the health risks of iodine nutritional status of residents in our country, this year, the National Food Safety Risk Assessment Expert Committee systematically evaluated the potential risks of iodine nutrition status of residents in different regions of our country from the aspects of urinary iodine level and dietary iodine intake. Evaluation results show that: from the population of urinary iodine levels and dietary iodine intake in two aspects of evaluation, in addition to high iodine areas in China, the vast majority of residents in the iodine nutritional status at a safe and appropriate level, the coastal areas is no exception; salt plus Iodine does not cause excessive iodine intake in our country’s residents; the health risk of iodine deficiency in our population is greater than the risk of iodine excess. Therefore, the continued implementation of salt iodization strategy is necessary to improve the iodine nutrition status of residents in most areas, including the coastal areas.
