Effect of DIET on Gulf War Illness
The Diet study will determine the effectiveness of two diets utilizing FODMAP (Fermentable Oligo-, Di- and Mono-saccharides and Polyols) carbohydrates.
Veterans with Irritable Bowel Syndrome and symptoms of Gulf War Illness will be assigned to two parallel, blinded, and randomized groups: 1) low FODMAP; and 2) high FODMAP. Participants will consume study-prepared meals for two weeks, maintain food diaries, and submit stool samples to evaluate microbiota.
