This study analyzed food price trends in Brazil during the COVID-19 pandemic (March 2020 to March 2022), using data from the Brazilian Household Budget Survey and the National System of Consumer Price Indexes. The research aimed to assess the impact of the pandemic on food prices and project future trends up to 2025. The study found that unprocessed or minimally processed foods and processed culinary ingredients were initially more affordable than ultra-processed foods (UPFP). However, trend analysis suggested a reversal of this pricing pattern, with UPFP becoming relatively cheaper than unprocessed or minimally processed foods. This shift is attributed to the impact of the pandemic on the global economy, leading to increased food prices and price dispersion. The study also highlighted that the rising prices of healthy foods exacerbate food and nutrition insecurity in Brazil, encouraging the replacement of traditional meals with unhealthy foods, which poses health risks to the population. The research underscores the need for government interventions to ensure food security and address the growing prevalence of non-communicable diseases. The findings suggest that long-term measures to reduce the price of healthy foods and increase the price of unhealthy foods are necessary. The study also notes that the economic crisis has worsened food insecurity in Brazil, with food prices increasing significantly during the pandemic. The research highlights the importance of policies that promote healthy diets and address the social and economic factors contributing to food insecurity.This study analyzed food price trends in Brazil during the COVID-19 pandemic (March 2020 to March 2022), using data from the Brazilian Household Budget Survey and the National System of Consumer Price Indexes.
