食品伙伴网讯 据欧盟食品安全局消息，应欧委会要求，5月7日欧盟食品安全局就碘的膳食参考值发表科学意见。
经过相应评估，欧盟专家组建议成年人碘的适宜摄入量（AI）为150μg/天，7 - 11个月婴儿和儿童为70-130μg/天，孕妇及哺乳期妇女为200μg/天。
考虑到欧盟不同地区妇女体内碘浓度差别较大，而且孕期与哺乳期之前阶段，如果体内情况较好，那么也会贮藏大量碘，因此将哺乳期妇女的AI值也设定为200μg/天。
部分原文报道如下：
Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies （NDA） was asked to deliver a scientific opinion on Dietary Reference Values （DRVs） for the European population, including iodine.
For pregnant women, T4 production is estimated to be increased by a mean of 37 ?g/day, corresponding to an additional iodine demand of 25 ?g/day for hormone synthesis in the thyroid. The additional requirements due to the development of the fetus, placenta and amniotic fluid were considered very low when related to the whole pregnancy （equivalent to a net transfer of 1 ?g iodine/day）。 Adding to this requirement the iodine needed for fetal synthesis of thyroid hormones, the total additional iodine reqirement is rounded to 50 ?g/day. Provided that thyroid status and iodine stores before pregnancy are adequate, an AI of 200 ?g/day is proposed for pregnant women. The Panel considered that the information available on the relationship between iodine intake or status of pregnant women and clinical outcomes, such as maternal thyroid function, infants being born small for gestational age or infants' neurobehavioural impairment, cannot be used for setting DRVs for pregnant women.
