A low FODMAP diet plus traditional dietary advice versus a low-carbohydrate diet versus pharmacological treatment in irritable bowel syndrome (CARBIS): a single-centre, single-blind, randomised controlled trial

Dietary interventions might be considered as an initial treatment for patients with IBS. Research is needed to enable personalised treatment strategies.
