Pilot Study for the Evaluation of Food Choices in Patients With Inflammatory Bowel Diseases (MICI2021)

Subjects with IBD will be recruited among the patients referred to the IBD clinic of the Policlinico of Milan. These patients are subject to annual check-ups during which, where possible, they will be asked to sign an informed consent. These patients are subjected during the visits of normal clinical follow-up to: * Questionnaire on eating habits for the patient with IBD versus control patients; * Modified Food Habits Frequency Questionnaire (FFQ), validated for the celiac population. The questionnaire assesses the extent, frequencies of consumption and quantity of gluten-containing foods in a year; this, in order to estimate the average introduction of gluten through the diet versus control patients; * Anthropometric and plicometric analysis; * Validated clinical activity questionnaires for RCU (ulcerative rectocolitis) and CD (Chron disease) (Mayo Score and Harvey-Bradshaw Index).
