The aim of this study was to analyse certain aspects of ethnocentric behaviour of vegetable purchasers in Warsaw. The research, in the form of a survey, was carried out among the adult population in 2015. Among the studied factors were consumers’ attitudes in relation to domestic and imported vegetables, depending on selected demographic characteristics. The analysis of empirical material has indicated ethnocentrism among vegetable buyers. Domestic vegetable purchases are primarily determined by practical advantages of the products. The choice of domestic products for mainly rational reasons points towards intentional ethnocentrism.
