[Expert Solution]: This research proposal will impact the…

This research proposal will impact the nutrition field in several ways. First, given the anticipated results, this research will contribute to the evolving understanding of how dietary patterns influence not only metabolic health, but also mental health and wellbeing through the gut-brain axis. Through demonstrating a link between adherence to the Mediterranean Diet (MD), individuals will see improvements in gut microbiome diversity, and subsequent reductions in the biomarkers of overweight/obesity, type 2 diabetes mellitus (T2DM), and mental health disorders. A unique feature of this study is that it offers a multidimensional lens for nutritional interventions. These findings will significantly impact current literature and reinforce the importance of adopting an integrative approach that considers the interconnectedness between dietary behaviors, metabolic health, and mental health. Moreover, this research will support the role of the MD as a non-pharmacological strategy for preventing and treating chronic conditions. Although these anticipated results are promising, this study will highlight the need for further research to investigate more longitudinal studies on the MD for managing weight and glycemic control, as well as improving quality of life. These findings can be used in educational lesson plans in schools, universities, or community programs, which will incorporate evidence-based resources on the MD role in improving gut health, metabolic, and mental health. Moreover, cooking demonstrations can be created to inspire individuals to try new and exciting recipes rooted in the MD. Additionally, these results can translate into clinical and community health resources including handouts and community workshops. Lastly, these results can inspire new policies and program developments which can create reform within our societies to move towards a more healthy and holistic world.
