The food is not only a mechanical intake of food, but very often is accompanied by a kind of conviviality, the pleasure of being together and eat: peer interaction, each is the bearer of values, beliefs and knowledge accumulated in other networks. This same interaction also passes by the consumption of food. Look at the ways in which citizens-consumers, to pursue more consistent behaviors to their principles, organizational models and socially remodel rules and norms, knowledge and material and symbolic practices affecting infrastructure (what is termed the socio-technical system) of food as a motor for development, and look at the barriers that they encounter at that location helps to identify and highlight the critical points of the process of transition to sustainable consumption. Equally useful is hinting at forms of "food citizenship" and how they can make community or new community. Over the past thirty years, forty years the concept of consumption of food (as well as how to study it and to interpret it) change significantly to hire a polysemous character. Consume food not only interested in the Act of purchase of tangible, but also desire, use, waste and recycling of an object that may be material as immaterial (the idea of wealth also passes for food): a variety of forms, sometimes very far apart, but that together define the phenomenon of food in all its complexity. social classes, genders and generations. Then, if the objects that surround us and the consumption of tangible and intangible assets help to define who we are, consuming food becomes a process that determines and resulted in new social capital formation, individual and collective identities, social classes, genders and generations and that, now, is forming a new community.
