title: [Food and Nutrition in Public Health: constitution, contours and scientific status].
abstract: This paper aims to examine the route on which Food and Nutrition in Public Health was build in the Brazilian context, from its fields of origin, identifying tensions and convergences, seeking to demarcate its boundaries and to characterize its status within the scientific field. We seek to evince the existence of a movement marked by the fruitful encounter between the field of "Public Health" and a portion of the field of "Food and Nutrition", or more precisely, one of their cores, starring actors oriented by knowledge distinguished from other nuclei in this field. Such phenomena, that we postulate as outcomes of the contact nuclei of knowledge that identify the Public Health with the field of "Food and Nutrition", led to a specific core of distinct knowledge and praxis in this context corresponds to what we call "Food and Nutrition in Public Health". This is a process marked from the outset by tensions between the biological and social paradigms, becoming the one hand, as a major challenge to be faced, and secondly, as a promising way for the approach between different fields of science, both the more practical, such as those targeted to conceptual reflection.
