The article explores consumer behavior in the context of sustainable consumption and the changes related to healthy food that have occurred during the pandemic. The study seeks to identify the factors that influenced consumer behavior on the consumption of fruits and vegetables. For this purpose, a questionnaire was applied to a sample of 1230 people from Maramures County, Romania. This study evaluates consumer behavior and attitudes on sustainable healthy food consumption; determining factors of consumer behavior are established by the needs, knowledge, selection of quality products, and the degree of culture and education in health diet issues. The study also presents a specific classification for fruits and vegetables in terms of consumer preferences and the clustering of local consumers by their interest in healthy food habits according to consumer culture, consumer loyalty, consumer needs, and consumer knowledge. In this study, it was revealed that consumer behavior consumption is not influenced by age, gender, or education. As a result of the correlation analysis, a positive relation was identified between the consumer preference, consumer attitude, and consumer behavior variables. The results of this study offer practical solutions and directions for future research on redesigning sustainable development of local, traditional foods. The new trend focuses on brand offerings and consumer needs for quality food and shows the consumer’s ethnocentrism and orientation for practical solutions.
