FODMAPS are also a good source of carbohydrate which if reduced could compromise our bodies’ fuel supply needed to run well. So despite FODMAPS being a common culprit, cutting them out altogether is not a good idea and working a sports Dietitian to figure out a plan to balance minimizing symptoms, but still getting the nutrition benefit of FODMAPS is important. For more info on FODMAPS, click HERE
