Background: Dietary choices and patterns have previously been associated with educational performance and overall academic success. However, medical students’ dietary habits are seldom studied in the literature.This study aims to comprehensively assess dietary habits and their relation with academic performance among medical undergraduates. Methods and Material: A cross-sectional study was conducted among 110 medical undergraduates over a period of one month using a pre-tested questionnaire encompassing questions on socio-demographics, dietary habits, and marks obtained in university exams to collect data. Based on their answers, students were given a dietary habit score and were categorized into having good, moderate, or bad dietary habits. Statistical tests were used to analyse relations between survey variables like gender, accommodation, dietary habit score, and academic performance. Results: A high dietary habit score was related to high levels of academic performance. In contrast, a low dietary habit score was related to low levels of academic performance. (P value = 0.0351). Students having good dietary habits scored an average mark of 583/900. Students having moderate dietary habits scored an average mark of 550/900. Students having bad dietary habits scored an average mark of 520/900 Conclusions: Our study confirms previously conducted studies on dietary habits and academic performance that find a positive relation with regular breakfast and frequent consumption of vegetables, pulses, and fruits and a negative relation with fast food.
