食品伙伴網(wǎng)訊  據(jù)歐盟食品安全局消息，應(yīng)歐委會(huì)要求，5月7日歐盟食品安全局就碘的膳食參考值發(fā)表科學(xué)意見(jiàn)。

　　經(jīng)過(guò)相應(yīng)評(píng)估，歐盟專家組建議成年人碘的適宜攝入量（AI）為150μg/天，7 - 11個(gè)月嬰兒和兒童為70-130μg/天，孕婦及哺乳期婦女為200μg/天。

　　考慮到歐盟不同地區(qū)婦女體內(nèi)碘濃度差別較大，而且孕期與哺乳期之前階段，如果體內(nèi)情況較好，那么也會(huì)貯藏大量碘，因此將哺乳期婦女的AI值也設(shè)定為200μg/天。

　　部分原文報(bào)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.
