Eating habits refer to the amount, type, and composition of the food that is consumed. They are shaped on many levels, by cultural, demographic, and social aspects. Education and profession also contribute to the formation of specific eating habits. Numerous studies have shown that healthcare workers have better knowledge of nutrition than the population at large. Given this context, medical graduates, including doctors, who will work to promote health in their future careers, should strive to develop and encourage healthy eating behavior among their peers, particularly students. The aim of this paper is to gather and analyze the available literature on eating habits and their potential effects on the health of medical students, as well as to document interventions to change eating behavior.
