A low-FODMAP diet consists of the global restriction of all fermentable carbohydrates (FODMAPs), and is recommended only for a short time. A low-FODMAP diet is recommended for managing patients with irritable bowel syndrome (IBS) and can reduce digestive symptoms of IBS, including bloating and flatulence.
Several studies have found a low-FODMAP diet to improve digestive symptoms in adults with irritable bowel syndrome, but its long-term use can have negative effects, because it has a detrimental impact on the gut microbiota and metabolome. It should only be used for short periods and under the advice of a specialist. More study is needed to evaluate its effectiveness in children with irritable bowel syndrome. Small studies (which are susceptible to bias) show little evidence of its effectiveness in treating functional symptoms of inflammatory bowel disease (IBD). More study is needed to assess the true impact of this diet on health.
