Americans' consumption of sodium, fat, and saturated fat exceed federally recommended limits for these nutrients and has been identified as a preventable leading cause of hypertension and cardiovascular disease. More than 40% of the Bronx population comprises African-Americans, who have increased risk and earlier onset of hypertension and are also genetically predisposed to salt-sensitive hypertension. This study analyzed nutrition information for packaged foods advertised in Bronx-based supermarket circulars. Federally recommended limits for sodium, saturated fat and total fat contents were used to identify foods that were high in these nutrients. The proportion of these products with respect to the total number of packaged foods was calculated. More than a third (35%) and almost a quarter (24%) of the 898 advertised packaged foods were high in saturated fat and sodium respectively. Such foods predominantly included processed meat and fish products, fast foods, meals, entrees and side dishes. Dairy and egg products were the greatest contributors of high saturated fat. Pork and beef products, fast foods, meals, entrees and side dishes had the highest median values for sodium, total fat and saturated fat content. The high proportion of packaged foods that are high in sodium and/or saturated fat promoted through supermarket circulars highlights the need for nutrition education among consumers as well as collaborative public health measures by the food industry, community and government agencies to reduce the amounts of sodium and saturated fat in these products and limit the promotion of foods that are high in these nutrients.
美国人钠、脂肪和饱和脂肪的摄入量超过了联邦政府对这些营养素的推荐限量，已被确定为高血压和心血管疾病的一个可预防的主要病因。布朗克斯区超过40%的人口是非裔美国人，他们患高血压的风险增加且发病较早，并且在基因上也易患盐敏感性高血压。本研究分析了在布朗克斯区超市传单上宣传的包装食品的营养信息。使用联邦政府对钠、饱和脂肪和总脂肪含量的推荐限量来确定这些营养素含量高的食品。计算了这些产品在包装食品总数中所占的比例。在898种宣传的包装食品中，分别有超过三分之一（35%）和近四分之一（24%）的食品饱和脂肪和钠含量高。这类食品主要包括加工肉类和鱼类产品、快餐、餐食、主菜和配菜。乳制品和蛋类产品是高饱和脂肪的最大贡献者。猪肉和牛肉产品、快餐、餐食、主菜和配菜的钠、总脂肪和饱和脂肪含量中位数最高。通过超市传单宣传的钠和/或饱和脂肪含量高的包装食品比例很高，这凸显了对消费者进行营养教育的必要性，以及食品行业、社区和政府机构采取合作性公共卫生措施，以减少这些产品中的钠和饱和脂肪含量，并限制对这些营养素含量高的食品的宣传。
