Discover what case studies say about plant-based diets.

Welcome to the case study evidence section of our evidence library, where we share detailed accounts of individual or small group experiences that highlight the benefits of plant-based diets in improving health and managing chronic conditions.

This page focuses on studies at the lower tier of the evidence pyramid, offering in-depth looks at how plant-based dietary interventions have impacted individuals or specific groups in real-world settings. Case studies are typically observational in nature, providing a closer examination of how plant-based diets can lead to improvements in conditions such as obesity, heart disease, diabetes, and more. While these studies lack the generalizability of larger trials, they provide valuable qualitative insights into the potential of plant-based eating for health transformation.
