Diet sustainability analyses inform policymaking decisions and provide clinicians and consumers with evidence-based information to make dietary changes. In the United States, the Food Commodity Intake Database (FCID) provides a crosswalk for integrating nationally representative data on food intake from the National Health and Nutrition Examination Survey (NHANES) with data on sustainability outcomes from other publicly available databases. However, FCID has not been updated since 2010 and does not link with contemporary NHANES data, which limits further advancements in sustainability research. This study fills this research gap by establishing novel linkages between FCID and NHANES 2011-2018, comparing daily per capita food intake with and without these linkages, and making these data publicly available for use by other researchers. To update FCID, two investigators independently established novel data linkages, a third investigator resolved discrepancies, and a fourth investigator audited linkages for accuracy. Dietary data were acquired from nearly 45,000 adults from 2001 to 2018, and food intake was compared between updated vs. non-updated FCID versions. Total food intake from 2011 to 2018 was 5-23% higher using the updated FCID compared to the non-updated version, and intake was over 100% higher in some years for some food categories including poultry, eggs, legumes, starchy vegetables, and tropical oils ( < 0.001 for all comparisons). Further efforts may be needed to create new food composition data to reflect new products and reformulations that enter the food supply over time. This study removes a barrier to further diet sustainability analyses by establishing a data crosswalk between contemporary NHANES and other publicly available databases on agricultural resource use, environmental impacts, and consumer food expenditures.
饮食可持续性分析为政策制定决策提供信息，并为临床医生和消费者提供基于证据的信息，以促使他们做出饮食改变。在美国，食品商品摄入数据库（FCID）提供了一个交叉平台，用于将来自国家健康与营养检查调查（NHANES）的具有全国代表性的食物摄入数据与其他公开可用数据库中的可持续性结果数据相结合。然而，FCID自2010年以来就未更新，且未与当代NHANES数据建立联系，这限制了可持续性研究的进一步发展。本研究通过在FCID和2011 - 2018年的NHANES之间建立新的联系、比较有无这些联系时的人均每日食物摄入量，并将这些数据公开供其他研究人员使用，填补了这一研究空白。为了更新FCID，两名研究人员独立建立新的数据联系，第三名研究人员解决差异问题，第四名研究人员审核联系的准确性。从2001年到2018年获取了近45000名成年人的饮食数据，并比较了更新后的FCID版本与未更新版本之间的食物摄入量。与未更新版本相比，使用更新后的FCID，2011年至2018年的总食物摄入量高出5% - 23%，在某些年份，包括家禽、鸡蛋、豆类、淀粉类蔬菜和热带油在内的某些食物类别摄入量高出100%以上（所有比较的P值均<0.001）。可能需要进一步努力创建新的食物成分数据，以反映随着时间推移进入食品供应的新产品和重新配方。本研究通过在当代NHANES与其他关于农业资源利用、环境影响和消费者食品支出的公开可用数据库之间建立数据交叉平台，消除了进一步进行饮食可持续性分析的障碍。
