超市使用销售通告来突出特定的食品，通常是降价的。由此产生的购买有助于形成家庭内的一套可用食物，个人和家庭可以从中选择吃什么。本研究的目的是确定每周超市销售通告中的食品与膳食指南的符合程度，以及饮食质量与美国人口摄入量的比较。2009年，中西部一家小型杂货连锁店每周52份销售通告中的食品和饮料项目（n= 9149）被编码，以获得食品类别、营养和能量含量。健康饮食指数-2010 （HEI-2010）的总得分和成分得分是使用国家癌症研究所开发的算法计算的。美国2岁以上人口的HEI-2010得分是根据2009-2010年全国健康和营养检查调查的数据估计的。采用学生t检验比较HEI-2010循环评分和人口摄入量。结果平均总分（42.8 / 100）低于美国人群（55.4 / 100）
Background Supermarkets use sales circulars to highlight specific foods, usually at reduced prices. Resulting purchases help form the set of available foods within households from which individuals and families make choices about what to eat.Objective The purposes of this study were to determine how closely foods featured in weekly supermarket sales circulars conform to dietary guidance and how diet quality compares with that of the US population's intakes.Design Food and beverage items (n=9,149) in 52 weekly sales circulars from a small Midwestern grocery chain in 2009 were coded to obtain food group and nutrient and energy content. Healthy Eating Index-2010 (HEI-2010) total and component scores were calculated using algorithms developed by the National Cancer Institute. HEI-2010 scores for the US population aged 2+ years were estimated using data from the 2009-2010 National Health and Nutrition Examination Survey. HEI-2010 scores of circulars and population intakes were compared using Student's t tests.Results Mean total (42.8 of 100) HEI-2010 scores of circulars were lower than that of the US population (55.4; P
