This paper discusses theoretical and methodological challenges in the production of knowledge located in the interface between the Social Sciences and the Sciences of Food and Nutrition, mediated by Health Sciences. We recognize that the discussion on the intersections between these scientific fields arises from the need to expand the understanding of the phenomena surrounding the field of Food and Nutrition from other theoretical frameworks beyond the biomedical paradigm. The discussion will guide a reflection on the following issues: a) how to establish Brazilian academic-scientific output at the interface between the Nutritional Sciences and Social Sciences, mediated by Health Sciences; b) considering that there is a 'field' of the socio-anthropology of food developed historically within the Social Sciences and Humanities, which distinguishes the production of knowledge in the field of health; c) the main theoretical and methodological challenges of academic-scientific output today. We also discuss challenges related to the practical consequences of this output, considering the interventionist legacy in the field of health. Lastly, we highlight that such reflections also face another important challenge, namely the urgent need to reinvent ways of thinking and doing science which, articulated with demands inherent to a new field shaped by the search for production of knowledge and practices, is more important to issues raised by health care.
