The 5Ad Diet for Functional Bowel Disorders

Plain-language summary

The goal of this randomised controlled trial (RCT) is to compare the efficacy of the newly developed 5Ad diet against the widely researched low fermentable oligo-, di-, monosaccharide and polyols (FODMAP) diet in reducing gastrointestinal symptoms associated with functional bowel disorders/food intolerances. The primary aims of this RCT are to determine: * Whether the 5Ad diet is at least as effective as the low FODMAP diet in reducing gastrointestinal symptoms associated with FBDs/food intolerances. * Whether either the 5Ad diet or the low FODMAP diet are effective in reducing mental and physical fatigue. To achieve the above aims, an RCT will be conducted with the 5Ad diet in one arm vs the active phase of the low FODMAP diet in the other arm, in a cross-over design with a 7 days washout phase in between. Both dietary protocols will be followed by each participant for 7 days. Researchers will compare the results from the 2 dietary protocols in order to ascertain the superiority of one over the other in regards to 6 gastrointestinal symptoms (abdominal pain, bloating, flatulence, bowel urgency, straining and incomplete defecation), stool form and frequency of defecation.
