This study documents the quality of diets among older Americans and implications of healthy eating for their physical and mental health. Using a nationally representative longitudinal sample of adults aged \u226550 years, from the Health and Retirement Study (HRS) 2010\u20132016 and food intake data from the 2013 Health Care and Nutrition Study (HCNS), the study evaluates the onset of health problems along the spectrum of diet quality measured by the Healthy Eating Index (HEI)-2015. Older adults adhering to healthier diets, in the high HEI group, have a significantly lower risk of developing limitations in activities of daily living (15.2% vs. 19.6%, p &lt; 0.01) and depression (11.8% vs. 14.9%, p &lt; 0.01), as compared to participants with low HEI scores. Consuming healthier diets also predicts more favorable health outcomes, as measured by blood-based biomarkers, including C-reactive protein (3.3 vs. 3.8, p &lt; 0.05), cystatin C (1.1 vs. 1.2, p &lt; 0.1), total cholesterol (192.1 vs. 196.4, p &lt; 0.1), and high-density lipoprotein (57.2 vs. 53.8, p &lt; 0.01). Most older Americans can benefit from improving diet to reduce their risk of disability, chronic disease, and depression.<\/jats:p>","DOI":"10.3390\/nu14061198","type":"journal-article","created":{"date-parts":[[2022,3,13]],"date-time":"2022-03-13T21:44:17Z","timestamp":1647207857000},"page":"1198","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["Diet Quality and Health in Older Americans"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0487-2423","authenticated-orcid":false,"given":"Hang","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Agricultural and Resource Economics, University of Connecticut, 1376 Storrs Road, Storrs, CT 06269, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5143-2378","authenticated-orcid":false,"given":"Tatiana","family":"Andreyeva","sequence":"additional","affiliation":[{"name":"Rudd Center for Food Policy and Health, Department of Agricultural and Resource Economics, University of Connecticut, One Constitution Plaza, Hartford, CT 06103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"591","DOI":"10.1001\/jama.2013.13805","article-title":"The state of US health, 1990\u20132010: Burden of diseases, injuries, and risk factors","volume":"310","author":"Murray","year":"2013","journal-title":"JAMA"},{"key":"ref_2","unstructured":"World Health Organization (2009).
