Diet and frailty syndrome - what do we know? a literature review

Introduction and purpose: Frailty syndrome is defined as a multidimensional degenerative process leading to a progressive loss of the body’s homeostasis and a significant increase in susceptibility to health deterioration under the influence of even minor stressors (Arroyo-Huidobro et al., 2025). Due to the progressive aging of the population, this syndrome is becoming a growing demographic problem and one of the main challenges for modern public health and geriatric care. The aim of this study is to summarize the existing knowledge on the relationship between diet and the risk of frailty syndrome in older adults. Materials and Methods: A narrative literature review was conducted using the PubMed, Scopus, and Web of Science databases. The analysis included observational and clinical studies as well as systematic reviews published up to 2025 that examined the association between the diet followed by older adults and their biological status, and consequently, the risk of frailty syndrome.
