Background: Peer teaching to college students can be an effective method for improving knowledge and attitudes toward healthy eating. MyPlate and Su-perTracker tools are valuable resources for healthy meal planning. However, awareness and knowledge of these tools are necessary to effect change. Objective: To evaluate university students' knowledge and attitudes about the USDA's MyPlate icon and SuperTracker tools before and after peer teaching by a nutrition major. Design: Cross-sectional online pre and post-survey administered to participants before and after peer teaching. Participants/Setting: 264 mixed majors enrolled in First Year Experience (FYE) classes at a large university were peer taught by upper class undergraduate nutrition majors on a relevant nutrition topic in 20-minute presentations that featured MyPlate and Super-Tracker tools. Statistical analyses performed: Descriptive statistics (frequencies, percentages) were used for categorical variables and parametric tests (independent paired t-test) were used for continuous variables. P < .05 was considered statistically significant. Results: The majority of participants were female (68.2%), freshmen (53.8%), white (83%), and non-nutrition majors (96.2%). Both males and females indicated favorable views towards the MyPlate icon post-presentation. From pre to post presentation, responses related to knowledge about portions (p < .001) and reminders to eat healthfully increased significantly (p < .001). After the presentation, 92.4% of students agreed that SuperTracker tools are useful for college students, and 88.6% thought they could benefit from using them. A confidential online survey was completed by the peer nutrition educators after their teaching experience. All who responded (14/16) indicated that their presentation skills improved as a result of the experience. Conclusion: Peer teaching
