Summary: A low-FODMAP diet, which is a common intervention for IBS, is being increasingly studied in IBD patients. Unfortunately, the diet does not currently show efficacy for reducing inflammation, but has been shown in clinical trials to be effective at managing functional gastrointestinal symptoms in patients whose disease is in remission. Although a common concern with low-FODMAP diets is potential adverse effects on the microbiome from removing fermentable substrates, its actual effects on the microbiome in practice have not yet been clearly characterized, with inconsistent results across studies. For those who wish to support their microbiome on a low-FODMAP diet, resistant starch and Sunfiber are good low-FODMAP prebiotic options.

The low-FODMAP diet is somewhat unique among IBD interventions because it promises to intervene in the common but oft-overlooked situation of continuing functional gastrointestinal symptoms even in the absence of inflammation.
I cover the basics and practical aspects of a low-FODMAP diet in The Low-FODMAP Diet for IBD: Everything You Need to Know. In this article, I take a deep dive into all the evidence regarding the effectiveness of a low-FODMAP diet for IBD, both from the perspective of reducing inflammation and managing symptoms. I also address the most common concern about a low-FODMAP diet: its effects on the microbiome.[Read more…] about Is the Low-FODMAP Diet Effective for IBD?
