What is the impact of Wheat Bran (insoluble fiber) on IBS?

• A. Wheat Bran increases symptoms of abdominal pain and bloating in IBS
• B. Wheat Bran reduces IBS symptoms
• C. Wheat Bran cures IBS
• D. Wheat Bran has no effect on IBS

Answer: (A)

Wheat bran, as an insoluble fiber, tends to worsen IBS symptoms because it adds bulk and speeds up transit through the gut. This can lead to greater bowel distension, triggering abdominal pain and bloating in a sensitive IBS gut. Unlike soluble fibers, which can form a gel and help smooth transit, insoluble fiber often increases gas and discomfort without reducing symptoms. So, for many individuals with IBS, bran is more likely to provoke symptoms than to provide relief, and it is not a cure or a universally effective therapy.
