背景：碘是甲状腺激素产生所必需的，并通过饮食获得。牛奶是美国饮食中碘的主要来源。本研究的目的是测量各种牛奶替代品中的碘含量，以确定牛奶替代品是否含有与牛奶相当的碘水平。方法：采用Sandell-Kolthoff反应的分光光度法测量来自16家不同公司的30种不同品牌的牛奶替代品中的碘水平。30个品牌的牛奶替代品平均含有3.1 +/- 2.5 μ g/250 mL（类似于8盎司）。或一杯，食用量）的碘或12.3 +/- 10.1 μ g/L（类似于24盎司。结论：这些结果表明，牛奶替代品含有的碘远远低于牛奶。限制乳制品消费的个体存在膳食碘摄入不足的风险。
Background: Iodine is necessary for the production of thyroid hormones and is acquired through the diet. Cow's milk is a primary source of iodine in the U.S. diet. The objective of this study was to measure the iodine content in a variety of milk alternatives to determine whether milk alternatives contain iodine levels comparable to that of cow's milk.Methods: Iodine levels from 30 different brands of milk alternatives from 16 different companies were measured by the spectrophotometric method of the Sandell-Kolthoff reaction.Results: The 30 brands of milk alternatives contained an average of 3.1 +/- 2.5 mu g/250mL (similar to 8 oz. or one cup, serving size) of iodine or 12.3 +/- 10.1 mu g/L (similar to 24 oz. or four cups, daily recommended serving for adequate calcium intake) of iodine.Conclusions: These results indicate that milk alternatives contain far less iodine than cow's milk. Individuals with restricted dairy product consumption are at risk for inadequate dietary iodine intake.
