Seventy‐three patients with irritable bowel syndrome (IBS) were randomly allocated into one of the following three groups: dietary advice with follow up (DAF) had repeated dietary advice from an experienced senior‐dietitian, dietary advice (DA) a single interview with the dietitian and no dietary advice (NDA) a diet‐sheet alone without explanation. An age, sex‐matched control group was recruited from staff at an institute for higher education. Fibre was assessed by a food‐frequency questionnaire at the beginning and end of the 6‐month study, and by a 7‐day weighed food inventory at the end of the study. There was no difference between the fibre intake of the patients and controls at the beginning of the study. After 6 months there was a mean increase of 7 g fibre/day by the patients (P<0.001) but no increase by the controls. There was no difference in the intake of the three dietary‐treatment groups either at the beginning or end of the study, whether assessed by questionnaire or weighed inventory. Only 14 patients achieved a daily intake of 30 g fibre during the week they weighed their food. This study suggests that although simple diet‐sheets given to patients without further explanation have their limitations, currently employed methods of dietetic counselling appear to offer little additional advantage.
