The Nasa people are characterized by their social organization, through which they have generated spaces of resistance to processes that affect the community, its culture, territory or beliefs; School feeding has become his main interest, in the search to verify the feeding from the traditional indigenous food system, which is ethnically and culturally appropriate. This research work intends to analyze from a decolonial approach the processes related to the school feeding of the Nasa People and their relationship with food sovereignty and food and nutritional security. To this end, open and semi-structured interviews aimed at key actors of the school feeding were interviewed at the Tóez Indigenous Reserve of the municipality of Caloto, Cauca. As main results, three processes that affect school feeding are included, from the institutional sector, the School Feeding Program and alternative processes as the food supplement implemented by the Association of Indigenous Cabildos of North Cauca (ACIN) and the Educational Project Agricultural Community. These alternative processes have generated an important impact on the educational community and are an important platform to strengthen food sovereignty and food security and nutritional security. That is working on decolonial methodology such as the revaluation of traditional forms of production, local production of healthier foods and with less impact on the environment and also favor social and ecological aspects from their own and different worldview, trying to transcend to other types of more human relationships.
