Abstract In the context of the microbiota-gut-brain axis, diet represents a critical yet still debated component of translational psychiatry. However, population-based evidence linking microbiota-supportive dietary patterns to depressive symptoms remains limited. This research leverages the Dietary Index for Gut Microbiota (DI-GM) to examine the associations between a gut-microbiota-friendly diet and depression, providing a theoretical framework for future research on practical applications.
