Description The objective of the study was to investigate to what extent and how the food preferences are reflected in consumption in large sample of adolescents. The research was conducted in 1655 adolescents at the age 15 years, in the framework of the ELSPAC study in the Brno district. Both food preferences (liking) and consumption frequency were investigated by questionnaire tools for 56 items in 8 food groups and 1 beverage group, and the relationship between preferences and consumption was analysed. The results show that preferences and consumption differ substantially and thus preferences reflect into consumption only partially. From 10 most preferred items only 2 were among 10 most consumed. From 10 least preferred items, 5 occurred among 10 least consumed, thus „negative preferences“ coincide with consumption rather more. The consumption was generally healthier than could be assumed according to preferences. Detailed analyse showed several types of association between preferences and consumption, according to different shapes of regression curves. Most items, 27 altogether, showed the „J“ type of association, but the items in sweets group showed solely „U“ type, while items in meat group showed mostly linear association. The main practical consequences of nonlinear associations are that some foods are consumed considerably more (or less) than it would correspond to their preferences. The possible explanations, based on various external influences, are discussed. The main conclusion is that preferences are not the most important determinates for consumption, which gives clear signal that the diet of adolescents is highly influenceable by external factors, optimally in favourable direction, by targeted preventive activities.
