The brain-gut interaction is considered as one of the most important mechanisms of IBS, after dietaly habits and gut microbiota have clarified its role for IBS. We extracted IBS by RomeⅢ and considered dietaly habits by BDHQ Questionnaire in a health promotion project (Iwaki Health Promotion Project). All participants of this project involved 1,167 people and IBS were 5.2% of all. We classified all participants in 3 groups ; Healthy dietary pattern, Western dietary pattern and Alcohol and accompanying dietary pattern. We compared each group as to IBS or not IBS participants, but there was no significant difference in each group. We also investigated gut microbiota in this study by examing fecal specimens with metagenomic analysis, and evaluated gut microbiota about 4 strains considerd to associate with IBS until now. Also in the evaluation of gut microbiota, there was no significant difference in each group. The mechanisms of dietaly habits and gut microbiota have not been well clarified and still unknown. We will have to consider the optimal evaluation methods about dietaly habits and gut microbiota in IBS.
