Gluten: friend or foe for elite athletes?

This trial investigates whether gluten consumption affects digestive comfort, quality of life, and physical performance in non-celiac athletes who train intensively. Participants, who are healthy and free of digestive diseases, will be randomly assigned to a gluten-containing or gluten-free diet. The study measures digestive symptoms, running performance, body composition, and gut microbiota to see if gluten sensitivity plays a role in athletic well-being.
