Abstract
Irritable bowel syndrome is the most common functional gastrointestinal disorder significantly affecting quality of life. The nutritional intervention with the greatest scientific support and most recommended by international guidelines is the low-FODMAPs diet, however, a relevant proportion of patients (between 20% and 50%) do not adequately respond to this intervention. This has prompted the exploration of alternative nutritional interventions, such as the starch- and sucrose-reduced diet and the Mediterranean diet. The aim of this study is to review the scientific evidence on new nutritional strategies for the management of irritable bowel syndrome, focusing on the the starch-sucrose reduced diet and the Mediterranean diet.
