This review synthesized the characteristics and effects of non\u2010pharmacological interventions on mealtime care and outcomes in people with dementia and their caregivers. Five databases were searched from January 2012 to October 2024. Eligible studies were accessed for study quality and graded for level of evidence. Meta\u2010analyses were performed for studies within the same intervention type that tested the impact on same outcomes. 33 studies were identified and categorized into five intervention types. Five studies were strong, 7 moderate, and 21 weak in quality. The levels of evidence varied from very low to moderate, with most being very low to low. Meta\u2010analyses showed \u201cresident training\/therapy\u201d decreased eating difficulties and increased food intake; \u201cNutritional supplement\u201d improved cognition and depression; \u201cenvironmental\/food modification\u201d increased food intake. Further research using rigorous designs is needed to increase evidence quality and determine effects of multi\u2010component interventions.<\/jats:p>\n                  <\/jats:sec>\n
