Background/Objectives Approximately 1 in 10 community-dwelling older adults are affected by or at risk of malnutrition, and this prevalence increases to nearly 1 in 3 among those receiving home care or recently hospitalized, contributing to higher rates of frailty, falls, hospitalization, functional decline, and mortality. Many of these individuals depend on informal or family caregivers for nutritional care, including assistance with grocery shopping meal preparation, feeding, and monitoring dietary intake. Thus, informal caregivers play an increasingly central role in supporting dietary intake and maintaining nutritional status. This narrative review aims at assessing the relationship between informal caregiver involvement and malnutrition in community-dwelling older adults who are dependent for nutritional-related needs, summarizing evidence on caregiver’s role and caregiver-associated determinants of malnutrition, as well as on interventions that incorporate caregivers into nutrition care. We discuss factors associated with malnutrition in later life, with particular emphasis on caregiver knowledge, burden, interventions and outcomes. In addition, caregiver-inclusive models of care and tools, including nutrition education and guidelines/recommendations, medical nutrition therapy, and multidisciplinary care models will be addressed. Methods: A structured review of the literature was conducted (date of last search December 2025), searching multiple databases for pertinent articles. Following identification of eligible articles for inclusion, a narrative synthesis of evidence was completed. Results and Conclusions: Despite the high degree of heterogeneity in methodology, observational studies demonstrate that several caregiver attributes influence the nutritional status of care recipients, including caregiver’s own nutritional status, burden, knowledge and literacy, psychosocial, environmental and economic factors. Intervention studies show that caregiver-focused, -inclusive and -delivered interventions have a positive impact on several outcomes, including improved older care recipient dietary intakes, nutritional status and quality of life without impacting on caregiver burden. Thus, strengthening caregiver support and integrating caregivers into nutrition screening and intervention frameworks may represent a critical opportunity to reduce malnutrition risk and improve health outcomes among older adults. Still, significant gaps remain in caregiver-focused intervention research, particularly in diverse cultural and social contexts.
