In this paper Talcott Parsons’ systems theory is applied to the food system. After the introduction of the basic categories of the food system, the main elements of Parsons’ theory are drawn up. Then, the detailed analysis takes place on three abstraction levels: within the general paradigm of human condition, the action system and the social system. During the analysis, two conclusions are formulated: one of them is in connection with the correction of abstraction levels concerning the food system, the other one creates the classes of the food system that can be corresponded to the four Parsonsian functions. In the end of the study, a final conclusion is formulated.
