[The national food and nutrition policy and its dialogue with the national food and nutrition security policy].

Food is one of the determinants and conditions of health and an inherent right of all people. The consequences of food and nutrition insecurity in the population, such as obesity, malnutrition and specific nutritional deficiencies, impact the health sector and have historically meant that it has assumed the responsibility for food and nutrition programs and policies in Brazil. However, ensuring food and nutrition security requires a combination of public policies, among which the National Food and Nutrition Policy of the Unified Health System (SUS) plays a fundamental role. This paper seeks to contribute to the debate on intersectoriality and health promotion based on presenting the National Food and Nutrition Policy and discussing its role as interface between the SUS and the National Food and Nutrition Security Policy and System. This perspective strongly suggests the combination of efforts to promote health and food and nutrition security in order to optimize initiatives developed in different sectors and accompanied by different policy councils that are not interrelated, enabling enhanced government and civil society action on the determinants of health and nutrition.
