An educational intervention, which involved 9 weekly meetings, was developed. A questionnaire was completed prior and subsequent to the intervention. Associations between variables were examined using a chi-square test (x2). RESULTS AND DISCUSSION:there was a significant reduction in the consumption of soft drinks and processed juices subsequent to the educational intervention (p = 0.007). It has further reduction in weekly consumption of food like meat and sausage (p = 0.072). Adolescents' weekly consumption of fried foods and potato chips also decreased significantly subsequent to the educational intervention (p < 0.001). CONCLUSIONS:the food and nutrition educational program was efficacious in reducing the adolescents' intake of high-calorie food and drinks and contributed to an improvement in the quality of food consumed by the schoolchildren evaluated. :Introdución: existe una alta prevalencia de sobrepeso y hábitos alimentarios pobres entre los adolescentes, y estos factores contribuyen al desarrollo de enfermedades crónicas.
