Based on Bourdieu's thoughts about the scientific fields, we visited the Research Groups Directory of the National Council for Scientific and Technological Development (CNPq), seeking to invest in critical and reflective approach on the segment of Brazilian research work concerned with "food". We identified a stable and growing set of research groups whose visibility is compromised, once its name is not included in the institutional taxonomies within the agencies that support research and researchers' formation. Its epistemological foundations, its theoretical and methodological bases are located in the sphere of Humanities and include a wide range of interacting disciplines, forming a significant complexity around its central object: food. The study of feeding phenomena calls for interdisciplinarity and makes the challenge of facing the tensions inherent to democratic life in which we have a glimpse in which the growing and collaborative coexistence among different epistemic references must take institutional place.
