From the date of study authorization, the principal investigator, together with his specially identified collaborators, will proceed to identify patients who meet the inclusion criteria. Then, during the first follow-up visit, the principal investigator, or one of his co-investigators, will deliver the informed consent to the parent(s) of the minor subject candidate for enrollment in the study, explaining all the characteristics and evaluations stipulated in the protocol and answering any questions. After the informed consent is signed, patients will be enrolled and the data required to conduct the study will be collected, and a fecal sample will be requested specifically for the conduct of the study. At the same time, completion of the KIDMED (Mediterranean Diet Quality Index in children and adolescents) questionnaire will be requested.
