Core Tip

Core Tip: This study investigated the dietary habits between irritable bowel syndrome (IBS) patients and non-IBS participants based on a multidimensional questionnaire. We found that quantity per time and intake frequency of some foods were positively associated with symptom and psychological status, especially soybean. The intake frequency of soybean and its products was an independent risk factor for IBS.
