Over 700 scientific papers and federal reports using the Healthy Eating Index (HEI) have been published since 2008 when the HEI-2005 was released. Published papers include analyses using the original HEI, HEI-2005, HEI-2010, and HEI-2015. The articles listed here are limited to federally authored papers and reports, particularly those related to the update and evaluation of the tool.
Healthy Eating Index Update and Evaluation Publications
Peer-reviewed articles describing how the HEI-2015, HEI-2010, and HEI-2005 were updated and evaluated for validity have been published in the Journal of the Academy of Nutrition and Dietetics (formerly, the Journal of the American Dietetic Association) and the Journal of Nutrition.
Update of the Healthy Eating Index: HEI-2015. Krebs-Smith S, Pannucci T, Subar A, Kirkpatrick S, Lerman J, Tooze J. J Acad Nutr Diet. 2018 Sep; 118(9):1591-1602.
Description: An updated HEI is released to correspond to each new edition of the Dietary Guidelines for Americans, and this paper introduces the latest version that reflects the 2015-2020 Dietary Guidelines for Americans. Also included are recommendations for interpreting the HEI using qualitative descriptors, as well as radar graphs, to reveal a visual pattern of diet quality.
Evaluation of the Healthy Eating Index-2015. Reedy J, Lerman J, Krebs-Smith S, Kirkpatrick S, Pannucci T, Subar A, Kahle L, Tooze J, Wilson M. J Acad Nutr Diet. 2018 Sep; 118(9):1622-1633.
Description: The main objective of this article is to evaluate the HEI-2015’s psychometric properties. Eight questions were examined, five relevant to construct validity, two related to reliability, and one to assess criterion validity.
Diet Quality: The Key to Healthy Eating. Hiza HAB, Koegel KL, Pannucci TE. J Acad Nutr Diet. 2018 Sep; 118(9):1583-1585.
Description: To help RDNs understand how efforts in nutrition education may result in better HEI scores, factors relevant to the scoring of the HEI are explained. Thus, this article describes the characteristics of the HEI dietary components that impact the scoring system. It also summarizes how the HEI scores relate to diet quality and health outcomes.
Testing the Predictive Validity of the Healthy Eating Index-2015 in the Multiethnic Cohort: Is the Score Associated with a Reduced Risk of All-Cause and Cause-Specific Mortality? Panizza CE, Shvetsov YB, Harmon BE, Wilkens LR, Marchand LL, Haiman C, Reedy J, Boushey CJ. Nutrients 2018; 10(4):452.
Description: These results, in a multiethnic population, demonstrate that following a diet aligned with the recommendations of the 2015-2020 Dietary Guidelines for Americans is associated with lower risk of mortality from all-cause cardiovascular diseases and cancer.

Guidance for Research Related to HEI-2015, HEI-2010 and HEI-2005
Researchers can access technical resources and tools on the following website -- National Cancer Institute Overview and Background of The Healthy Eating Index. Information includes guidance for calculating HEI scores, including information to help researchers choose the most appropriate method and sample SAS codes for various types of analyses.
Applications of the Healthy Eating Index (HEI) for Surveillance, Epidemiology and Intervention Research: Considerations and Caveats. Kirkpatrick S, Reedy J, Krebs-Smith S, Pannucci T, Subar A, Wilson M, Lerman J, Tooze J. J Acad Nutr Diet. Anticipated September 2018.
Description: The objective of this paper was to review potential applications of the HEI, including those relevant to surveillance, epidemiology, and intervention research, and to summarize available guidance for appropriate analysis and interpretation. Steps in calculating HEI scores were reviewed and statistical methods described. Consideration of salient issues in the calculation and interpretation of scores can help researchers to avoid common pitfalls and can help reviewers to ensure that articles reporting on the use of the HEI include sufficient details such that the work is comprehensible and replicable, with the overall goal of contributing to knowledge on dietary patterns and health.
Healthy Eating Index-Beyond the Score. Schap T, Kuczynski K, Hiza H. J Acad Nutr Diet. 2017 Apr; 117(4):519.
Description: This journal article described the breadth of HEI applications established in the literature and highlighted more information about how researchers use the HEI to study diet quality.

In 1995, the original Healthy Eating Index was developed by the USDA Center for Nutrition Policy and Promotion, in cooperation with USDA's Food and Consumer Service and Agricultural Research Service, to measure how well the diets of Americans align with the Dietary Guidelines for Americans. While the main purpose of the HEI has remained the same throughout the series of HEI updates, the design and application of the current HEI have changed substantially since its inception. These new features are reflected beginning with the HEI-2005. Documentation related to the original HEI has been archived.
