Ethnonutrition is the study of diets in the context of food systems of different peoples and cultures. Its scope comprises native or local categories used to classify food, and also includes biodiverse food availability, local culinary techniques, seasonality, and cultural perceptions related to diet with nutritional implications. Here, we describe a method useful for gathering ethnonutrition data to design dietary interventions or assessments, the Rapid Ethnonutrition Assessment (REA). REA is a tool that offers food and nutrition research a broad biocultural view of diets, considering food system-level, by prototyping dietary assessments with high efficiency. This method permits us to prevent misinterpretations that lead to wrong conclusions in nutritional research.
