Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Objective: To evaluate the efficacy of an educational nutritional intervention, based on the Social Cognitive Theory, to increase the consumption of vegetables and fruits and decrease the consumption of ultra-processed foods, in adolescent high school students at the University of Guadalajara (UDG), in Guadalajara, Jalisco, in the year 2022.
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. A multilevel analysis will be used to compare post-intervention variables between groups.

Intervention
Educational nutritional intervention, based on the Social Cognitive Theory
ALIADA: Alimentación, Adolescencia y Ambiente
The objective of the educational nutritional intervention is to promote in adolescents an increase in their consumption of vegetables and fruits and a decrease in their consumption of ultra-processed foods, through the application of the TSC constructs, with the use of education by pairs as the main strategy (peer leaders). It lasts two months, includes three exclusive sessions for peer leaders and five sessions for all participants, where the leaders, together with the researchers, will lead the activities of the sessions, as well as a general event for all high school students. Intervention activities include: electronic presentations, videos, food preparation and label reading workshops, individual and team reflection activities, goal setting and monitoring, board games, contests, among others. In addition, each participant is given a workbook, which contains key messages and activities for each educational session.
