Abstract

Abnormal reactions to food probably contribute to the complex pathophysiology of irritable bowel syndrome, but the mechanisms involved remain unclear. Following the recent identification of subtle mucosal inflammation in at least some patients with the disorder, perhaps now is the time to revisit some of the immunological reactions to dietary antigens that, in the past, have been dismissed as irrelevant.
