This working paper analyzes the effects of the Covid-19 pandemic on food security and food consumption in Brazil. The data was collected between November and December 2020 through a public opinion survey conducted by telephone with a representative sample of the Brazilian population. This data collection was coordinated by the Research Group Food for Justice: Power, Politics and Food Inequalities in a Bioeconomy, of the Freie Universität Berlin (Germany), jointly with researchers from the Universidade Federal de Minas Gerais (UFMG) and the Universidade de Brasília (UnB). The results show that 59% of the inquired households are in a situation of food insecurity during the pandemic, and that a significant part of the respondents reduced the consumption of food items important for their regular diets; 44% reduced meat and 41% reduced fruit consumption. Thus, the data collected confirms the previous findings by the National Research for Sample of Domicile (Pesquisa Nacional por Amostra de Domicílio) that indicated an increase in food insecurity in Brazil in the years 2017 and 2018 compared to the previous standards from 2013. In conclusion, the socioeconomic instabilities caused by the political and economic crises in recent years have worsened with the Covid-19 pandemic, reinforcing food inequalities for a large portion of the Brazilian population, especially regarding access to healthy food on a regular basis in a sufficient quantity and quality.
