Nutr."],"abstract":"<jats:p>This narrative review examines how socioeconomic disparities accelerate health decline in older adults. As the global population ages, older age represents a major risk factor for chronic diseases, frailty, and disability, particularly in socially disadvantaged groups. While adequate nutrition is essential to healthy aging, approximately 28% of the global population experiences moderate or severe food insecurity, with older adults disproportionately affected in resource-limited settings. Food insecurity and financial hardship are consistently associated with poorer diet quality, including lower Healthy Eating Index scores (e.g., ~51 vs. &amp;gt;57 in food-secure peers), and increased risk of adverse outcomes such as sarcopenia, frailty, and cognitive decline. Notably, food-insecure older adults are also more likely to experience overweight or obesity (OR \u2248 1.29), reflecting reliance on energy-dense, nutrient-poor diets. These disparities are shaped by structural and socioeconomic factors, including low income, limited education, inadequate social safety nets, and inequitable neighborhood food environments. Addressing these challenges requires a shift from individual-level interventions to systemic, interdisciplinary, and culturally-tailored approaches.<\/jats:p>","DOI":"10.3389\/fnut.2026.1833736","type":"journal-article","created":{"date-parts":[[2026,6,8]],"date-time":"2026-06-08T04:23:04Z","timestamp":1780892584000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Socioeconomic
