Analysis of dietary content composition is increasingly being conducted in the social sciences as well as in nutrition, but not yet in the analysis of day-to-day decision-making processes. In this study, a conceptual model of the decision-making process of dietary content composition was constructed based on the conceptual model of the decision-making process in consumer behavior theory, the role of institutions （habits, routines） in the action by Hodgson and Bourdieu’s idea of lifestyle as a normative system called habitus. The actual decision-making process was then ascertained through a questionnaire survey and semi-structured interviews incorporating the laddering method, for 15 women; 20s~30s, single, with a job, 30s with husband and children aged 3 to primary school, and 60s, a couple. The results showed that when family members were present, the norm of a family-oriented lifestyle was at work, forming a dietary norm of preparing a structured, elaborate meal with dinner as a central part of the meal. Singles, on the other hand, were divided between simple or absent meals and elaborate meals. In addition, a type had been formed for each diet, which was used as a routine, with limited decision-making taking into account the situation at the time. The above provided some validation of the conceptual model.
