You might refer you doctor to the research paper referenced below which was mentioned in one of Heather's newsletters and the abstract is in the research library. There is an email address at the end of the abstract that you can use to ask for a pdf copy of the article so you take it to your doc.
This article is a review of 17 research studies on fiber and IBS. It concludes
Quote:
The role of fibre in the pathophysiology of irritable bowel syndrome remains poorly understood. An increase in the amount of dietary fibre is an almost universal recommendation in the primary care management of irritable bowel syndrome, and guidelines on irritable bowel syndrome management for out-clinic patients advise an increase in fibre intake in the event of constipation. However, our review showed only limited support for this recommendation.
In summary, our systematic review demonstrates the effectiveness of fibre therapy in irritable bowel syndrome patients, but only in terms of either global symptom improvement or constipation. The effectiveness on individual symptoms is variable. There is no effect of fibre in irritable bowel syndrome-related abdominal pain. Soluble and insoluble fibre have different effects on global irritable bowel syndrome symptoms. Insoluble fibre is probably no better than placebo and may, in some patients, even worsen the clinical outcome. For the development of evidence-based management guidelines, valid clinical studies in primary care patients, focusing on the effectiveness and tolerability of soluble and insoluble fibre, are needed.
While this review article does not directly address the role of white bread (or sourdough bread) it does specifically state that IF may worsen IBS symptoms while SF likely doesn't.
