This study aims to follow the work of some researchers that have used sociodemographic variables to try to explain food consumption patterns. Specifically, it tries to update and improve Heien, Lovell, and Perali’s (1989) work on Mexican food consumption. These authors used the 1977–78 ENIGH data to estimate the effects of demographic variables on food consumption in Mexico. First, a brief description of some studies related to food consumption is presented. Then, the structure of general consumption and the role of food consumption in Mexico are explained. The model to be used to relate food consumption and demographic variables is described, and then the results are presented. Finally, some comparisons and conclusions are drawn, and some suggestions are given
