Brief Summary

To evaluate the effect of interventions based on choice architecture on the consumption of vegetables in school meals. Non-randomized community trial with historical control. Students aged 7 to 12 (n=148) enrolled in public elementary schools. Generalized linear model for repeated samples by intention to treat was applied to evaluate changes in vegetable consumption after the intervention. After the intervention, the consumption of vegetables in school meals at least once a week increased. The study showed that actions characterized by simplicity, ease of reproduction and low cost, such as those implemented in this study, lead to favourable changes in the food consumption and eating habits of elementary school students. After an intervention based on nudges with primary school students in a public school, the chance of consuming vegetables in school meals increased twofold, and the students were more willing to try new vegetables among those included in the school meals menu.
