The influence of eating habits on the academic performance of university students.

OBJECTIVE

To explore the correlation between eating habits of university students and academic achievement.

PARTICIPANTS

577 undergraduate students at a university in the United States.

METHODS

Students were invited to participate in an anonymous online survey that asked questions concerning health-related behaviors; participants were asked to report their current grade point average (GPA). Statistical analyses were performed using the JMP software program; a standard least squares regression was used to test whether self-reported current GPA was related to different types and rates of weekly food and drink consumption.

RESULTS

Self-reported GPA did not change along with weekly rates of milk, vegetables, green salad, fruit juice, or fresh fruit consumption. Breakfast consumption had a positive effect on self-reported GPA, while fast food consumption had a negative effect.

CONCLUSION

Healthy eating habits have a positive effect on students' academic performance. However, other factors, such as sleep habits, may be more important.
