Nutritional Challenges in the Aging Population: A Narrative Overview
DOI:
https://doi.org/10.56861/nut.v1i1.34Keywords:
Aging population; malnutrition; public health nutritionAbstract
The global increase in the aging population presents complex nutritional challenges with significant implications for health systems and public policy. As people age, physiological, metabolic, and socio-economic factors converge to affect nutritional intake, leading to heightened vulnerability to malnutrition, frailty, and chronic diseases such as sarcopenia, osteoporosis, and cardiovascular disorders. This narrative review explores the multifactorial etiology of malnutrition among older adults, including age-related changes in metabolism, reduced appetite, polypharmacy, and social isolation. It further discusses dietary patterns, protein requirements, and emerging interventions—both nutritional and exercise-based—to support healthy aging. Additionally, the review emphasizes the critical role of healthcare professionals in screening and implementing personalized nutritional strategies. Advancing knowledge in this area is essential to improve quality of life, prolong healthspan, and reduce healthcare burdens in an aging society.
