The sodium concentration (mg/100g) for 23 of 125 Sentinel Foods (e.g. white bread) were identified in the 2009 CDC Packaged Food Database (PFD) and compared with data in the USDA's 2013 National Nutrient Database for Standard Reference(SR 26). Sentinel Foods are foods identified by USDA to be monitored as primary indicators to assess the changes in the sodium content of commercially processed foods from stores and restaurants. Overall, 937 products were evaluated in the CDC PFD, and between 3 (one brand of ready-to-eat cereal) and 126 products (white bread) were evaluated per selected food. The mean sodium concentrations of 17 of the 23 (74%) selected foods in the CDC PFD were 90%-110% of the mean sodium concentrations in SR 26 and differences in sodium concentration were statistically significant for 6 Sentinel Foods. The sodium concentration of most of the Sentinel Foods, as selected in the PFD, appeared to represent the sodium concentrations of the corresponding food category. The results of our study help improve the understanding of how nutrition information compares between national analytic values and the label and whether the selected Sentinel Foods represent their corresponding food category as indicators for assessment of change of the sodium content in the food supply.
在2009年疾病控制与预防中心（CDC）的包装食品数据库（PFD）中确定了125种哨兵食品（如白面包）中23种的钠含量（毫克/100克），并与美国农业部2013年《国家营养数据库标准参考版》（SR 26）中的数据进行了比较。哨兵食品是美国农业部确定的作为主要指标进行监测的食品，用于评估商店和餐馆中商业加工食品钠含量的变化。总体而言，在CDC的PFD中评估了937种产品，每种选定食品评估的产品数量在3种（一种即食谷物品牌）到126种（白面包）之间。CDC PFD中23种选定食品中的17种（74%）的平均钠含量是SR 26中平均钠含量的90%-110%，6种哨兵食品的钠含量差异具有统计学意义。PFD中选定的大多数哨兵食品的钠含量似乎代表了相应食品类别的钠含量。我们的研究结果有助于更好地理解国家分析值与标签之间的营养信息对比情况，以及选定的哨兵食品作为评估食品供应中钠含量变化指标时是否代表其相应的食品类别。
