This study will evaluate a culinary nutrition intervention designed to improve the quality of meals served to older adults participating in a senior center. Many meals currently provided in these settings do not meet recommended dietary guidelines, which negatively impact health outcomes among older adults. In this pilot study, participants will receive improved lunch meals that are designed to be more nutritious, culturally appropriate, and acceptable, along with nutrition education sessions over a 6-month period. This intervention will also include training for food service staff to support implementation of the improved meals. The study will assess changes in dietary quality, physical health measures, and social and behavioral outcomes among participants at baseline, 3 months, and 6 months. Findings from this study will help determine the feasibility and effectiveness of this approach and inform future efforts to improve nutrition and health outcomes in Congregate Meal Program for older adults.
