AIM:To investigate whether composite yogurt with acacia dietary fiber and Bifidobacterium lactis (B.lactis)has additive effects in irritable bowel syndrome (IBS).METHODS:A total of 130 patients were randomly allocated to consume,twice daily for 8 wk,either the composite yogurt or the control product.The composite yogurt contained acacia dietary fiber and high-dose B.lactis together with two classic yogurt starter cultures.Patients were evaluated using the visual analog scale via a structured questionnaire administered at baseline and after treatment.RESULTS:Improvements in bowel habit satisfaction and overall IBS symptoms from baseline were significantly higher in the test group than in the control group (27.16 vs 15.51,P =0.010,64.2 ± 17.0 vs 50.4 ± 20.5,P ＜ 0.001; respectively).In constipation-predominant IBS,improvement in overall IBS symptoms was significantly higher in the test group than in the control group (72.4 ± 18.4 vs 50.0 ± 21.8,P ＜ 0.001).In patients with diarrhea-predominant IBS,improvement in bowel habit satisfaction from baseline was significantly higher in the test group than in the control group (32.90 vs 7.81,P =0.006).CONCLUSION:Our data suggest that composite yogurt enriched with acacia fiber and B.lactis has greater therapeutic effects in patients with IBS than standard yogurt.
