Sodium Monitoring Dataset

The Agricultural Research Service of the US Department of Agriculture (USDA) in collaboration with other government agencies has a program to track changes in the sodium content of commercially processed and restaurant foods. This monitoring program includes these activities: Tracking sodium levels of ~125 popular foods, called "Sentinel Foods," by periodically sampling them at stores and restaurants around the country, followed by laboratory analyses. Tracking levels of "related" nutrients that could change when manufacturers reformulate their foods to reduce sodium; these related nutrients are potassium, total and saturated fat, total dietary fiber, and total sugar. Sharing the results of these monitoring activities to the public periodically in the Sodium Monitoring Dataset and USDA National Nutrient Database for Standard Reference and once every two years in the Food and Nutrient Database for Dietary Studies. The Sodium Monitoring Dataset is downloadable in Excel spreadsheet format.美国农业部（USDA）农业研究服务局联合其他政府机构，推出了一项用于监测商业加工食品及餐饮食品钠含量变化的项目。该监测项目包含以下工作内容： 1. 对约125种热门食品（称为“哨兵食品（Sentinel Foods）”）开展监测：定期在全美各地的商店与餐厅采样，随后进行实验室分析。 2. 监测相关营养素水平：当食品制造商调整食品配方以降低钠含量时，这些营养素的水平可能发生变化，相关营养素包括钾、总脂肪与饱和脂肪、总膳食纤维以及总糖。 3. 定期向公众共享上述监测活动的结果：相关数据会发布在《钠监测数据集（Sodium Monitoring Dataset）》与《美国农业部标准参照国家营养数据库》中，且每两年会在《膳食研究食品与营养数据库》中更新一次。 《钠监测数据集》可通过Excel电子表格格式下载。
