Intake of french fries decreased significantly (P < .05). Females responded better to the intervention than males in increasing vegetable consumption (P < .05).

CONCLUSIONS AND IMPLICATIONS

Class-based nutrition intervention focusing on prevention of chronic diseases is a cost-effective approach to increasing fruit and vegetable consumption among college students.
