Eating, nourishment or nutrition circulate in our culture as synonyms and thus do not account for the changes that occur in nourishment, which intended or unintended, have a hybridization pattern that represents a change of rules and food preferences. This paper aims to take these common sense conceptions as analytic categories for analyzing and interpreting research for the Humanities and Health Sciences in a theoretical perspective, through conceptualization. The food is associated with a natural function (biological), a concept in which nature is opposed to culture, and nourishment takes cultural meanings (symbolic), expressing the division of labor, wealth, and a historical and cultural creation through which one can study a society. One attributes to Nutrition a sense of rational action, derived from the constitution of this science in modernity, inserted in a historical process of scientific rationalization of eating and nourishing. We believe that through the practice of conceptualization in interdisciplinary research, which involves a shared space of knowledge, we can be less constrained by a unified theoretical model of learning and be freer to think about life issues
