Overview: A new study led by scientists from Anglia Ruskin University and published in the Journal of the International Society of Sports Nutrition, “found that a low FODMAP diet reduces some of the issues caused by exercise, such as stomach cramps and bloating, and improves a person’s perceived ability to exercise,” according to a Anglia Ruskin University statement. About 30 to 50 percent of runners experience GI issues . The researchers found that more than two-thirds of the study participants who eliminated FODMAPs from their diet were able to alleviate their gastrointestinal issues. For this study, FODMAP foods were defined as those containing lactose (milk, yogurts and cheese), fructans (found in cereals, breads and pasta), galactic-oligosaccharides (legumes and onions), excess fructose (for example, apples, pears and asparagus) and polyols (often used as food additives).
From the Research: “Research has demonstrated that low fermentable oligosaccharide, disaccharide, monosaccharide and polyol (FODMAP) diets improve gastrointestinal (GI) symptoms in irritable bowel syndrome sufferers. Exercise-related GI issues are a common cause of underperformance, with current evidence focusing on the use of FODMAP approaches with recreationally competitive or highly trained athletes. However, there is a paucity of research exploring the potential benefit of FODMAP strategies to support healthy, recreational athletes who experience GI issues during training. This study therefore aimed to assess whether a short-term low FODMAP diet improved exercise-related GI symptoms and the perceived ability to exercise in recreational runners.”
