The school is seen as the space for developing a variety of knowledge, including health issues. The adoption of educational practices with schoolchildren is necessary as children acquire the dietary pattern of adults, with higher intake of ultra-processed foods. However, educational activities should take place in a participatory manner in order to favour learning and the adherence of subjects to the proposed content, and these subjects can share their views on the methodology applied, using focal groups, to collect data in qualitative research. 125 students enrolled in the 3th to 5th year of Fundamental Education in a Comprehensive Centre for Public Education, aged between eight and ten years, participated. Food education activities have been carried out through culinary workshops, candons and a collective lanche, using educational material to address topics linked to food groups and healthy eating. The students participated from a focal group at the end of the project, which allowed the opportunity to display the content developed during the workshops and gunmen. Most classes have shown that they have been successful in apprenticeships. Further studies on the importance of nutrition for quality of life could be developed with the participation of the whole school.
