Marketing is the social and managerial process through which individuals obtain what they need and want in creating and exchanging products. The literature on food consumer behavior has been receiving significant interest during the covid-19 pandemic, and studies highlight diverse research on business. This article seeks to examine the covid-19 pandemic and its implications for the food consumer behavior in Brazil. To that end, the Methodi Ordinatio was applied to identify the most relevant studies in the area, which supported the research, analysis, selection and systematic reading of 25 articles identified in Web of Science and Scopus databases. vosviewer and EndNote software were used in this study for the reference management process and clustering themes and researchers. Our findings show the importance of advances in vaccination, an increase in home office work, home food safety practices, and an increase in food purchases in supermarkets. We conclude that the main financial problems faced during this period are unemployment and debt, while the increased use of food delivery apps emerges as an opportunity. Recent studies mention environmental awareness, sustainable consumption, and social responsibility as key topics. As a suggestion for future research, the authors recommend marketing research involving the regulatory role of pro-social consumption and family farming in times of covid-19.
