Abstract Changes in environmental conditions may influence the biosynthesis of several food nutrients. This study aimed to compare macronutrient and mineral composition over different seasons in 25 fresh plant-based foods that are highly consumed and locally produced in the southern Ecuadorian highlands. Samples were collected during the rainy season (October 2015–March 2016) and dry season (April–September 2016) from main local markets and supermarkets. Analyses of composite samples were carried out in triplicate following AOAC methods, determining moisture by desiccation, ash by calcination, total fat by Weibull, total nitrogen by Kjeldahl, total carbohydrates by difference, phosphorus by colorimetry, and minerals (Na, K, Mg, Ca, Fe, Se, Cu and Zn) by atomic absorption spectroscopy. Overall, during the rainy season, significantly higher moisture content was observed (86.7 ± 9.0% vs. 85.9 ± 8.9%, p
