Introduction: Proper nutrition based on scientific knowledge leads to a longer, healthier and higher quality life of an individual or population. It ensures an optimal ratio of proteins, carbohydrates and fats. It is extremely important for the physical and psychological development of young people, especially students who are exposed to higher stress level and psychological strain during their studies. Less time is devoted to what one eats, one cooks minimally and usually eats fast food. Many people today live in poor socioeconomic conditions. That is why they are forced to buy cheap and low quality food. Many illnesses and conditions can be prevented or at least their consequences reduced through timely changes in diet and the way of living. Aims of the study: Determine the socioeconomic and sociodemographic characteristics of students, their eating habits, nourishment status and their knowledge on the impact of nutrition on health. Materials and methods: The survey included 412 graduate students of University J.J. Strossmayer Osijek and was conducted through an online anonymous questionnaire from May 22 – June 10, 2019. Results: Students generally declare that they eat and live healthy. Students living in student homes have breakfast the most rarely, compared to other students; while students who live with their parents consume fruits and vegetables more often than the students who chose the option “other”. Students of the Faculty of Medicine Osijek, Faculty of Dental Medicine and Health Osijek, Faculty of Food Technology Osijek and Faculty of Agro-biotechnical Sciences Osijek scored significantly higher on questions relating to knowledge about healthy diet and eating habits. Conclusion: Most students have good eating habits and live healthy. Knowledge about the connection between nutrition and health is good and it is evident that students of health faculties and those who live in a city or suburban areas have better knowledge than other examinees.
