The objective of the study was to analyze from a nutritional and energetic point of view the weekly menu practiced in the canteen of a national college from Slobozia city, Romania, and its optimization in order to ensure a balanced diet for students. The research was carried out, in the first phase, based on the analysis of the nutritional and energetic value of the menu and the next phase consisted of conducting an opinion poll based on a questionnaire, which aimed to analyze students food preferences. The weekly average energy value of the menu served at the school canteen is 2893.81 kcal / day, a value that covers the energy needs of girls, but for boys it is insufficient.
