3Treatment groups
Experimental Treatment
Active Control
Placebo Group
Group I: 100% FructoseExperimental Treatment1 Intervention
The fructose group will help to determine whether an absolute amount of fructose will lead to IBS symptoms.
Group II: Fructose and GlucoseActive Control1 Intervention
The glucose/fructose mixture group is a cross comparison group that will determine whether the relative excess fructose concentration is an important cause of IBS symptoms.
Group III: 100% GlucosePlacebo Group1 Intervention
The glucose group will serve as a control since glucose is not a FODMAP and as a result is not expected to lead to recurrent symptoms.
