FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols which are a certain class of carbohydrates, that are more difficult for people to digest. The low-FODMAP diet temporarily restricts these carbohydrates in order to relieve uncomfortable symptoms and give your digestive system a rest. Removing irritants gives your gut lining a chance to repair itself and can help restore a healthy balance of gut flora.
