  • Patients with the irritable bowel syndrome (IBS) commonly report the precipitation of symptoms on food ingestion. Though the role of dietary constituents in IBS has not been extensively studied, food could contribute to the onset of symptoms in, or even the causation of, IBS through a number of mechanisms. Firstly, the physiological response of the intestine to food ingestion could precipitate symptoms in predisposed individuals; secondly, there is some evidence that allergy or intolerance to a particular food can produce IBS-like symptoms; thirdly, foods may alter the composition of the luminal milieu, either directly, or, indirectly, through effects on bacterial metabolism and thus induce symptoms and, finally, IBS may develop following exposure to food-borne pathogens. Not surprisingly, there is considerable interest in the potential roles of diet and food supplements in the therapy of IBS; for the most part, the evidence base for such recommendations remains slim though certain probiotics which exert anti-inflammatory effects show considerable promise.
