Children and adolescents need adequate and healthy nutrition, more than other age groups, in order to achieve adequate physical growth and mental development. Children need to teach nutrition in order to obtain the necessary skills for a proper selection of foods. To examine the effectiveness of a training intervention to improve eating behaviors of students. Quasi-experimental, pre-post-test design with a control group. Participants were elementary students (n = 65 total, n = 31 intervention, n = 34 control group) and male.
