Evidence of changes caused by the COVID-19 pandemic in food security and nutrition conditions, as well as in different food environments, has called researchers' attention to substantial changes taking place in individuals' dietary habits. The aim of this study is to present and address changes that have already happened in food environments, during the first COVID-19 pandemic year, in a middle-income country. Multiple changes were observed and had direct impact on the population, among them, worsened health and nutrition indicators and advanced dietary inequalities, as well as on its food profile in different life cycles, if one takes into consideration aspects such as food availability, financial access and dietary quality.
