Curr Opin Clin Nutr Metab Care. 2017 Sep;20(5):414-419. doi: 10.1097/MCO.0000000000000398.


Purpose of review: The low FODMAP diet is now recognized as first-line therapy for treatment of irritable bowel syndrome (IBS) symptoms including abdominal pain, gas, bloating, diarrhea and or constipation. This information must be disseminated for application to clinical practice.

Recent findings: There are many people with IBS worldwide who can benefit from following the low FODMAP diet to alleviate or minimize symptoms. Clinical studies and trials demonstrating the positive outcomes of the low FODMAP diet have been based on diet education provided by dietitians. Understanding the types of carbohydrates that are high in FODMAPs and the associated symptoms, nutrition intervention can be targeted using the low FODMAP diet. The nutrition intervention is relatively in expensive, noninvasive and basically without side-effects if monitored by a dietitian and clinical team.

Summary: Applying the low FODMAP diet in IBS can greatly improve health and quality of life outcomes by alleviating or significantly improves symptoms.
