Gluten
Gluten is a kind of protein that people are typically allergic to. This condition is also called celiac disease. It would trigger symptoms that are quite similar to those in diarrhea-predominant IBS. In addition, many people with IBS tend to be gluten intolerant. This means their body cannot digest this substance as usual and lead to diarrhea. The only way to improve the condition is to stay away from gluten-containing foods and look for gluten-free alternatives. [8]
