The aim of the study was to evaluate and compare the preferences and the frequency of consumption of milk and its products among adolescents and their mothers. The examined population included 449 adolescents aged 13 to 15 years (262 girls and 187 boys) and their mothers from the Warsaw and Garwolin regions. The dairy products preferred the most, and the most frequently consumed, by adolescents included fruit-fermented milk beverages, ripening cheeses, milk and plain homogenous cheeses. Whereas the mothers indicated ripening cheeses, plain fresh cheeses, fruit-fermented milk beverages and milk as the most preferred and the most frequently consumed dairy products. There were observed differences in preferences and frequency of dairy products consumption between adolescents and their mothers. The differences in the preferences referred, to a high extent, to processed cheeses, plain fresh cheeses and cream, whereas in the frequency of consumption - to processed cheeses, cream and plain homogenous cheeses. Girls tended to be more similar than boys to their mothers in respect of preferences as well as the frequency of dairy products consumption.
