[From production to impacts on health and the environment: an analysis of food systems in Brazil, Colombia and Panama].

The scope of this article is to describe the main components of the food systems of Brazil, Colombia and Panama. It involved a narrative review of the literature from 2000 to 2022, based on the concept of food systems proposed by the Committee on World Food Security. A system of agro-industrial production, monoculture, use of pesticides and exploitation of natural resources predominates in all three countries, and the area occupied by family farmers is reduced.
