背景：大多数美国人摄入的钠超过了推荐量，其中绝大多数来自商业包装和餐馆食品。2010年，美国医学研究所（Institute of Medicine）建议制造商减少产品中的钠含量。目的：目的是评估2009年在美国杂货店销售的商业包装食品中的钠含量。设计：利用商业来源的销售和营养数据，我们创建了一个数据库，其中包含2009年美国主要杂货店销售的近8000种包装食品。我们估计了美国饮食中钠含量最高的食物组中钠含量的销售加权平均值和分布（毫克/份、毫克/100克和毫克/千卡）。我们估计了每个类别中超过1)食品和药物管理局（FDA）使用“健康”标签声明的食品中钠含量限制的产品比例，以及2)1150毫克/份或2010年美国人膳食指南中推荐的最大日摄入量的50%。结果：肉类混合菜肴类别的产品每份钠含量的平均值和中位数最高（分别为966和970毫克）。沙拉酱和植物油类产品每100克的平均和中位数浓度最高（分别为1072和1067毫克）。汤类的钠密度最高（18.4 mg/kcal）。在分析的20个食品类别中，有11个类别中超过一半的产品超过了FDA对标有“健康”标签的产品的限制。在4类产品中，有10%的产品超过1150毫克/份。结论：美国主要杂货店销售的包装食品中的钠含量差异很大，很大一部分最畅销的产品超过了限制，表明有可能减少。持续监测是评价减钠进展的必要条件。
Background: Most Americans consume more sodium than is recommended, the vast majority of which comes from commercially packaged and restaurant foods. In 2010 the Institute of Medicine recommended that manufacturers reduce the amount of sodium in their products.Objective: The aim was to assess the sodium content in commercially packaged food products sold in US grocery stores in 2009.Design: With the use of sales and nutrition data from commercial sources, we created a database with nearly 8000 packaged food products sold in major US grocery stores in 2009. We estimated the sales-weighted mean and distribution of sodium content (mg/serving, mg/100 g, and mg/kcal) of foods within food groups that contribute the most dietary sodium to the US diet. We estimated the proportion of products within each category that exceed 1) the Food and Drug Administration's (FDA's) limits for sodium in foods that use a "healthy" label claim and 2) 1150 mg/serving or 50% of the maximum daily intake recommended in the 2010 Dietary Guidelines for Americans.Results: Products in the meat mixed dishes category had the highest mean and median sodium contents per serving (966 and 970 mg, respectively). Products in the salad dressing and vegetable oils category had the highest mean and median concentrations per 100 g (1072 and 1067 mg, respectively). Sodium density was highest in the soup category (18.4 mg/kcal). More than half of the products sold in 11 of the 20 food categories analyzed exceeded the FDA limits for products with a "healthy" label claim. In 4 categories, >10% of the products sold exceeded 1150 mg/serving.Conclusions: The sodium content in packaged foods sold in major US grocery stores varied widely, and a large proportion of top-selling products exceeded limits, indicating the potential for reduction. Ongoing monitoring is necessary to evaluate the progress in sodium reduction.
