The objective of research was evaluation of importance of individual sources of information on food products in the opinion of consumers while making their decisions on food purchasing. The authors stated that respondents declare their great interest in information displayed on the product packaging, indicated by them as the main source of information about food. As the least important sources consumers considered press articles, TV and radio programmes, information found on Internet, advertising, consumer organisations, info-lines of producers and sellers. The analysis of findings shows that there are substantial differences in evaluation of the importance of individual sources of information depending on the sociodemographic factors.
