To determine the impact of the 2007–08 FFVP on food intake, volunteer students from 4th–6th grade in 21 treatment and 2 control schools completed anonymous questionnaires at start and month 8 of the school year. Responses to 18 items were grouped into total fruits (TF), vegetables (TV), low nutrient foods (TLNF). Data were processed for missing values, univariate and multivariate outliers, and subjected to 4‐way MANOVA (2 gender × 3 grades × 2 treatment × 2 time) to examine TF, TV, and TLNF intake. Controls ate more TLNF at month 8 (p<0.01) while treatment students did not (p=0.94). The treatment × time interaction was not significant for TF or TV intake (p=0.18, p=0.10). To further examine intake, 4‐way ANOVA was used to analyze the 18 items independently. When time × treatment interactions were significant, simple main effects were tested for the difference between time for each treatment group. Fresh, canned and frozen fruit intake increased in treatment (p<0.01) but not controls (p=0.41). Control but not treatment students ate more frozen desserts (p=0.02, p=0.18). Intake of vegetables varied, e.g., potato (not fried) decreased in treatment with no change in controls (p=0.04, p=0.17), bean decreased in treatment but increased in controls (p<0.01, p<0.01) and mixed vegetable did not change in treatment but increased in controls (p=0.67, p=0.02) Thus, FFVP improved some but not all food behaviors.
