This essay explores the convergences and singularities of popular education and Food and Nutrition Education based on biographical fragments of the undergraduate training program in Nutrition of three university professors who established their academic and professional trajectories at these crossroads of knowledge and actions mediated by popular education. Inspired by the autobiographical method, the narratives revealed that the initial indignations with social inequalities were mobilizing the routes in the formative path toward understanding hunger, suffering, and human care. To this end, seeking spaces and opportunities to learn about and experience social work in contexts of vulnerabilities was a decisive factor in their personal and professional constructions, revealing the contradictions of traditional training models and the starting point for the genesis of critical thinking. Thus, clues are offered to understand the interfaces of Popular Education (PE) and Food and Nutrition Education (FNE) in the converging actions around the fight against hunger and the right to food without, however, reducing one to the other when food and Nutrition are projected on the horizon of practices.
