Background: It is known that the knowledge that guides our practices is socially elaborated and that the variability in food choices is related to the variability in living conditions. Objetive: To inquire about practices (actions) and representations (underlying ideas) about the feeding of families with at least one child from 3 to 6 years old living in different socio-economic environments of the Villaguay district, Entre Ríos, Argentina. Methodology: In public educational establishments of the urban (Ur), periurban (Pe) and rural (Ru) areas of the department of Villaguay, parents were invited to voluntarily develop assisted surveys, obtaining a total of 303 surveys (109 Ur, 133 Pe and 61 Ru). Results and Conclusions: The analysis of the data showed differences between zones for some practices and representations, also exhibiting their close relationship with the variability of the living conditions. For example, while urban families of higher socioeconomic status chose their food primarily for brands, in the most deprived families of the periurban, price was the determining factor. Finally, the rural area had intermediate socio-economic characteristics and a greater participation of the whole family in activities related to food was observed. However, certain uniformities, independent of the socio-economic differences, were also detected, such as the practice of eating between meals or the concern to achieve "a good food", noting that some aspects transcend the boundaries of socio-cultural subsystems.
