This report provides an update from the U.S. Department of Agriculture - Centers for Disease Control and Prevention Sentinel Foods Surveillance Program, exploring changes in sodium and related nutrients (energy, potassium, total and saturated fat, and total sugar) in popular, sodium-contributing, commercially processed and restaurant foods with added sodium. In 2010-2013, we obtained 3432 samples nationwide and chemically analyzed 1654 composites plus label information for 125 foods, to determine baseline laboratory and label sodium concentrations, respectively. In 2014-2017, we re-sampled and chemically analyzed 43 of the Sentinel Foods (1181 samples), tested for significant changes of at least ±10% ( < 0.05), in addition to tracking changes in labels for 108 Sentinel Foods. Our results show that the label sodium levels of a majority of the Sentinel Foods had not changed since baseline (~1/3rd of the products reported changes, with twice as many reductions as increases). Laboratory analyses of the 43 Sentinel Foods show that eight foods had significant changes ( < 0.05); sodium content continues to be high and variable, and there was no consistent pattern of changes in related nutrients. Comparisons of changes in labels and laboratory sodium shows consistency for 60% of the products, i.e., similar changes (or no changes) in laboratory and label sodium content. The data from this monitoring program may help public health officials to develop strategies to reduce and monitor sodium trends in the food supply.
本报告提供了美国农业部疾病控制与预防中心哨兵食品监测计划的最新进展，该计划旨在探索添加了钠的受欢迎的、含钠量高的、商业加工和餐馆食品中钠及相关营养素（能量、钾、总脂肪和饱和脂肪以及总糖）的变化。在 2010-2013 年，我们在全国范围内获得了 3432 个样本，并对 125 种食品的 1654 个复合材料加标签信息进行了化学分析，以分别确定实验室和标签钠浓度的基线。在 2014-2017 年，我们重新采样并对 43 种哨兵食品（1181 个样本）进行了化学分析，检测了至少±10%（<0.05）的显著变化，此外还跟踪了 108 种哨兵食品的标签变化。我们的结果表明，自基线以来（约有 1/3 的产品报告了变化，其中减少的比例是增加的两倍），大多数哨兵食品的标签钠含量没有变化。对 43 种哨兵食品的实验室分析显示，有八种食品的钠含量发生了显著变化（<0.05）；钠含量仍然很高且变化不定，相关营养素的变化也没有一致的模式。标签和实验室钠含量变化的比较表明，有 60%的产品具有一致性，即实验室和标签钠含量有相似的变化（或没有变化）。该监测计划的数据可能有助于公共卫生官员制定减少和监测食品供应中钠趋势的策略。
