The aim of the study was to examine the nutritional behaviour of young adults depending on gender. A survey was conducted among 467 young adults using the "Questionnaire for the study of nutritional behaviour and opinions on food and nutrition". Questions concerned the frequency of consumption of selected groups of food products. The questionnaire was supplemented by questions regarding the number of portions of fruits and vegetables consumed, putting sugar in drinks, putting salt in dishes and the number of glasses of water drunk. Differences in nutritional behaviours were determined using the χ2 test, at p < 0.05. The dietary choices of women more often than those of men corresponded to the principles of healthy nutrition, related to a greater number of meals consumed during the day, more frequent consumption of fruits and vegetables and the selection of products with lower energy value or preferring healthier methods of culinary processing. Health education programs should prevent the emergence of unfavourable dietary habits such as skipping breakfast or other meals or limiting the consumption of fruits and vegetables and frequently replacing them with high-energy snacks.
