Educational Nutritional Intervention to Increase the Consumption of Vegetables and Fruits and Decrease the Consumption of Ultra-processed Foods in Adolescents: Randomized Controlled Trial by Conglomerates
Randomized controlled trial by conglomerates whose objective is to evaluate the effectiveness of an educational nutritional intervention, based on the Social Cognitive Theory, for the increase in the consumption of vegetables and fruits and the decrease in the consumption of ultra-processed foods in adolescent high school students, in the University of Guadalajara, in Guadalajara, Jalisco.

Material and methods: Randomized controlled trial by conglomerates, students from the school groups chosen at random, from two high schools (one as a control group and another intervention) also chosen at random will be included. Adolescents who agree to participate will complete pre- and post-intervention assessments on fruit and vegetable consumption and ultra-processed foods.
