The Effects of Added Enzyme α-Galactosidase at a Carbohydrate-rich Meal in Irritable Bowel Syndrome (IBS)

"The study is conducted during a total of two days at two different occasions. Visit 1: The patients will be served breakfast and lunch at the gastro unit and dinner will be enclosed when the patient leave for home. At each meal (breakfast, lunch, and dinner) the participants will ingest three capsules with a total content of 1200 GaIU alpha-galactosidase-randomized to be either the enzyme (α-Galactosidase) or a non-active substance (placebo). Visit 2: The procedure from visit 1 will recur after at least two weeks has passed - except that the content of the capsules will be opposite from the first visit.~No other food or beverage are ingested from 1800 hours the evening before the intervention day until breakfast the day after intervention (no exact time)."
