Dynamic conceptual framework to investigate healthy food consumption in food insecure brazilian households through microsimulation modelling

This study developed a dynamic conceptual framework to support microsimulation modeling of healthy food consumption in Brazilian households experiencing food insecurity. The framework integrates sociodemographic factors, food environment, and prices using national surveys, literature review, and expert consultation. It highlights macro and household-level interactions that influence food choices and access, including regional disparities and public policies. Designed for future simulations, the framework aims to inform strategies that promote healthier diets and reduce nutritional inequities, contributing to the 2030 Agenda for Sustainable Development.
