Background: We tested the effectiveness of the Go Wild With Fruits and Veggies! (GWWFV) Extension curriculum on increasing fruit and vegetable (FV) intake of third graders. Methods: An intervention study was used testing self-reported FV intake pre/post GWWFV. Recruited schools were randomized to control (12 schools, N = 369, third grade children) or intervention (14 schools, N = 378, third grade children). Measures included items from a validated FV food frequency survey. Access to the federal Fresh Fruit and Vegetable Snack Program (FFVSP), and taste testing within GWWFV were also measured. Between-group differences in FV intake were evaluated using 1-way ANOVA for unadjusted models and 1-way ANCOVA for baseline adjusted models. The Tukey-Kramer test was employed for post hoc comparisons. Results: Students with access to the FFVSP consumed more fruits (p < 0.01) and vegetables (p < 0.0001). Students who participated in the FFVSP and GWWFV with taste testing consumed more fruits and vegetables (p < 0.05) compared with students who participated in the FFVSP and GWWFV without taste testing, along with the control group. Conclusions: The FFVSP and GWWFV with taste testing demonstrated a positive influence on FV intake in third grade children. Leveraging environmental approaches with interactive learning experiences create desired outcomes.
