The study presents the theoretical, methodological and practical tasks of researching the problems of the food supply system and the order of their presentation. The structure of the marketing research toolkit of the food supply system was systematized. Three categories of participants in the process of marketing research in the field of food supply are distinguished: users, users/executors, executors. It was concluded that the need for scientific (marketing) research of the food supply system to solve the problem of food security is determined by a social need that requires study and research and appears as a kind of social order. A theoretically oriented study of the field of food provision of the food security system, which is aimed at analyzing the current problem of modern society, is no less practical than applied marketing research in this field. Its results are the identification and assessment of the closeness of relationships, the determination of the direction of the development vectors of processes, the analysis of conditions that provoke or eliminate the dissonance of the interaction of elements and spheres of such a complex socio-economic entity as the food supply system. The practical component of such research is an in-depth understanding of the problems of the functioning of the food complex, the nature of the integration of these issues into the system of parameters of the quality of life of the population, parameters of the competitiveness of the regions and the country as a whole.
