Healthy and balanced nutrition is the basis of health and adequate quality of life. Increasing proportions of industrially processed foods rich in unhealthy fats and high in sugar cause obesity, and thus risks to overall human health, especially in terms of the risk of developing diabetes and cardiovascular disease. Due to the importance of quality and proper nutrition in the life of every person, the subject of research was the students’ nutrition and nutritive habits. The aim of the study was to determine whether there is a statistically significant relationship between dietary quality and eating habits and the BMI index of respondents. A survey was conducted on a sample of N = 163 respondents to determine the quality of nutrition and eating habits of students. The results of the study showed that the number of meals and consumption of "fast food", which is mainly prepared by deep-frying, has a statistically significant effect on the BMI index in terms of increasing the risk of obesity. Regarding the number of meals, respondents who consumed a larger number of smaller meals per day had a lower propensity for obesity.
