Support for a low FODMAP diet

Melinda Dennis MS, RDN, LDN

Q: I have celiac disease and follow the gluten-free diet. I also have irritable bowel syndrome (IBS). Where can I find online support for following the Low FODMAP diet?


First, a very brief review of the Low FODMAP Diet:  Irritable bowel syndrome (IBS) can be a co-existing disorder found in patients with celiac disease and other diseases where the motility (movement) of the gut is affected. Research has found that a low FODMAP diet is the most effective way known today to manage the symptoms of IBS, such as gas, bloating, cramping and bowel changes.

The acronym FODMAPs stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols, a sophisticated name for specific sugars found in food that can cause a wide range of symptoms in sensitive individuals. The Low FODMAP diet TEMPORARILY avoids these FODMAP-rich foods for a 2-6 week period and then reintroduces them, one by one, to test tolerance and find symptom relief. This process is complex and very individualized with each person.  It should only be done under the care and management of a registered dietitian specializing in FODMAPs who will make sure the patient has a healthy, balanced diet, particularly in this case since the patient is combining two diets.   

When counseling patients in nutrition clinic on the temporary low FODMAP diet and rechallenge, I recommend using evidence-based resources that are designed and operated by registered dietitians, physicians, and/or researchers.  A few examples of these types of resources are listed below, but please remember that these suggestions are provided for support and guidance only and should be used IN ADDITION to a consultation with a registered dietitian.
