If stomach troubles affect your endurance training, the low FODMAP diet could help. Standing for fermentable oligosaccharide, disaccharide, monosaccharide and polyols, FODMAPs are poorly absorbed short-chain carbohydrates that can increase diarrhoea, bloating and gas in some people. By restricting your intake of these foods, particularly around strenuous exercise, you may fi nd gut symptoms improve. Various studies have found that athletes switching to a low FODMAP diet experience noticeable improvements in their gut symptoms, which in turn can improve performance. Monash University has developed an app (monashfodmap.com) that helps you fi nd out which foods are high or low in FODMAPs. Examples of foods to avoid include gluten products, lactose, apples, onions, garlic, pulses, dried fruit and honey. Whereas CLIF Shots, Hammer gels and Jelly Belly Sport Beans are all low FODMAP energy options.
