INTRODUCTION: Diet plays an important role for patients with irritable bowel syndrome (IBS). The aim of this study was to compare the diets in terms of food consumption and nutrient intake between subjects with IBS and controls in a large French population.

METHODS: This study included 36,448 subjects from the Nutrinet-Santé cohort study, who completed a questionnaire pertaining to functional bowel disorders based on the Rome III criteria. Dietary data were obtained from at least three self-administered 24 h records via the internet. Association between IBS and diet was evaluated by comparison tests controlled for gender, age and total energy intake (ANCOVA tests).

RESULTS: Subjects included were mainly women (76.9%) and the mean age was 50.2 ± 14.2 years. Among these individuals, 1870 (5.1%) presented with IBS. Compared to healthy controls, they had significantly lower consumption of milk (74.6 versus 88.4 g/day; p < 0.0001), yogurt (108.4 versus 115.5 g/day; p = 0.001), fruits (192.3 versus 203.8 g/day; p < 0.001), and higher soft non-sugared beverages (1167.2 versus 1122.9 ml/day; p< 0.001). They had higher total energy intake (2028.9 versus 1995.7 kcal/day; p < 0.001), with higher intakes of lipids (38.5 versus 38.1% of total energy intake; p = 0.001) and lower intakes of proteins (16.4 versus 16.8% of total energy intake; p < 0.0001), as well as micronutrients (calcium, potassium, zinc and vitamins B2, B5 and B9, all p < 0.0001).

CONCLUSIONS: In this large sample, these findings suggest that dietary intake of subjects suffering from IBS differs from that of control subjects. They may have adapted their diet according to symptoms following medical or non-medical recommendations.
