Beyond Physical Health: The Role of Diet in Adolescent Mental Well-being and Academic Success

Background: The critical link between dietary habits, mental wellbeing, and academic performance in adolescents is increasingly recognized. However, a gap exists in understanding student perceptions of this link and its empirical validation within specific educational contexts. Objective: This study aimed to investigate secondary school students' perceptions of how diet impacts mental health and to analyze the relationship between dietary choices and academic outcomes statistically. Methods: A cross-sectional study was conducted with 129 female students from grades 9 and 10, randomly selected from public schools in Jaranwala tehsil, Faisalabad. Data were collected via a validated, structured questionnaire. Analysis was performed using SPSS, employing descriptive statistics (mean, standard deviation, ranking) and multiple linear regression. Results: Participants strongly perceived that dietary choices significantly impact mental health, ranking health stability (Mean=4.13) and emotional balance (Mean=4.02) as the most affected domains. Regression analysis revealed that dietary factors related to thinking power (β = -0.958, p<0.001) and digestive function (β = -0.623, p<0.001) were the strongest significant predictors of academic performance, explaining 32.5% of its variance (Adj. R²=0.325). The negative coefficients indicate that poorer dietary habits are associated with poorer academic outcomes. Conclusion: Students acknowledge the importance of diet for mental health. The findings provide strong evidence that dietary choices are significant predictors of academic performance, highlighting the need for school-based nutritional education programs to enhance both wellbeing and academic achievement.
