What is known and what is unknown about food buying and consumption behavior during the COVID-19 pandemic? A systematic literature review

Purpose - This study aims to analyze the management and marketing literature on food buying and consumption behavior during the COVID-19 pandemic to shed light on how consumers reacted to this global crisis, to help interpret consumer reactions to possible future crises and to identify future research avenues.Design/methodology/approach - This study adopts a systematic literature review as research methodology.Findings - This study's outcomes reveal that, during the pandemic, people have deeply changed their food buying and consumption habits. The analysis identifies four main themes: food purchasing channel choice and buying behavior; food choices and consumption habits; food and "food-related " waste; and country influence on food buying and consumption.Research limitations/implications - This review uses only one database of records (Scopus). The Boolean modifiers chosen for extracting the papers may have influenced the type and number of retrieved publications. The analysis was limited to articles published in peer-reviewed academic journals.Originality/value - While most examined investigations do not provide a comprehensive picture of consumers' food-related responses to the pandemic and individually offer only a partial view focusing on one or just a few aspects of food consumer behavior, this study offers an overall description of consumers' responses to the crisis and identifies important research issues to be addressed in the future.
