[National policies and the field of Food and Nutrition in Collective Health: the current scenario].

It is presented a review of the guidelines implementation of the National Food and Nutrition Policy (PNAN) contextualizing the actions in the Brazilian Unified Health System (SUS) scenario. At ten years of its publication, PNAN faces challenges both to expand and qualify the shares of food and nutrition on health. It is challenging to stand as interlocutor and legitimate representative of the area of health, political and institutional context of food security and nutrition. Issues related to the articulation of PNAN and future National Policy on Food and Nutrition Security will be analyzed to demonstrate the convergence of agendas among the priorities for the guarantee of the SAN. The authors identify the potential of this field of action, from the current institutional setting, and the need for comprehensive solutions that address the complexity of food and nutrition in health.
