Abstract

Composite food samples from adult, infant, and toddler market baskets of the Food and Drug Administration's (FDA) Total Diet Study for Fiscal Year 1980 were analyzed for iodine by neutron activation analysis (NAA) at the FDA NAA laboratory at the National Bureau of Standards. The mean iodine content of the total diets was 412, 397, and 410 micrograms, per day for adult (2,900 kcal per day), infant, and toddler diets, respectively. These intakes correspond with 275%, 882%, and 586% of the adult, infant, and toddler Recommended Dietary Allowances, respectively. Dairy products and iodate-containing breads were major dietary sources of iodine. The iodine values for total diets reported here, determined by NAA, are from 11% to 15% higher than those determined by colorimetric analysis at FDA's Kansas City Field Office Laboratory.

摘要

美国食品药品监督管理局（FDA）1980财年总膳食研究中成人、婴儿和学步儿童市场篮子中的复合食品样本，在国家标准局的FDA中子活化分析（NAA）实验室通过中子活化分析测定碘含量。成人（每天2900千卡）、婴儿和学步儿童总膳食的碘平均含量分别为每天412、397和410微克。这些摄入量分别相当于成人、婴儿和学步儿童推荐膳食摄入量的275%、882%和586%。乳制品和含碘酸盐面包是碘的主要膳食来源。此处报告的通过NAA测定的总膳食碘值，比FDA堪萨斯城外地办事处实验室通过比色分析测定的值高11%至15%。
