We Are What We Eat: Assessing the Use of a Documentary Film as an Educational Tool to Change Students’ Nutritional Attitudes and Behaviors

Background: Identifying effective educational strategies to change lifestyle behaviors related to eating habits is imperative for health professionals providing education related to disease management and prevention. The purpose of this study is to investigate the use of mass media as a tool for improving dietary habits. Methods: 151 Undergraduate students participated in a quasi-experimental control group design at a midsize liberal arts university. The treatment group watched the film Forks Over Knives and was assessed on their dietary habits, locus of control, and current stage of change before and after viewing the film. Results: Results showed differences to current stage of change in reducing animal-based food consumption in the treatment group but did not show significant changes in increasing plant-based food. Discussion: This study provides evidence that use of the documentary Forks Over Knives affects students’ intake of animal-based foods but is not an impactful enough tool to increase intake of plant-based foods. Translation to Health Practice: Professionals who utilize the film Forks Over Knives to encourage dietary changes should do so as part of a more structured, long-term behavior change intervention program. Additional research is needed to compare Forks Over Knives with other documentary films that encourage plant-based dietary habits.
