Growing bodies of literature show that a controlled diet is important in controlling the symptoms of Inflammatory Bowel Diseases (IBD). This leads patients to avoid foods considered potentially harmful. However, food is not just a nutrient but entails a series of hedonistic, cultural and social values. Thus, there is the concern that having to renounce certain foods might exert an impact on patients' psychosocial quality of life, particularly in younger patients. The aim of this paper is to review the existing literature to address which aspects of the patients' quality of life are affected by food restrictions. A scoping review was carried out. Five different databases were searched in January 2021. Retrieved papers were then screened to only include the relevant studies. Data were extracted and the main results of the studies were charted. A thematic analysis was carried out on the main results to identify the areas of psychosocial quality of life more often impacted by the food restrictions. From the initially identified 1967 unique entries, 14 studies were included. Results show that the perceived importance of food in controlling symptoms is confirmed by patients' accounts. The most common strategy adopted was, thus, the avoidance of trigger foods. The thematic analysis revealed three domains that are impacted by these restrictions: psychological quality of life, social life, family sphere. This study highlights the impact that food restrictions exert on IBD patients' quality of life, and warrants further studies to fill existing gaps, in particular regarding younger patients.
