Effects of Juice on Gastrointestinal Tolerance and Breath Hydrogen Response in Human Subjects

February 23, 2016 updated by: University of Minnesota

Effect of a White Grape Juice Compared to Apple Juice on Gastrointestinal Tolerance and Breath Hydrogen Response in Human Subjects

The goal of this study is to determine subjective gastrointestinal tolerance response and differences in breath hydrogen response following the consumption of two types of juice. This double-blind crossover study requires participants to arrive to the lab 12 hours fasted, consume 12 oz of juice and complete gastrointestinal tolerance questionnaires as well as produce samples for breath hydrogen analysis at various time points over the next 3 hours. Subjects will be asked to complete additional questionnaires at 12 and 24 hours post consumption, from home. Subjects will also be asked to keep a food record for 24 hours prior to their scheduled visit times to assure compliance.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in gastrointestinal tolerance from baseline
Time Frame: 24 hours
Subjects will answer a 7 symptom questionnaire regarding the intensity of gastrointestinal symptoms experienced following juice consumption. Questionnaire is adapted from the validated Bovenschen gastrointestinal tolerance questionnaire. Questionnaire is to be completed at the following time points: baseline, 30 min, 60 min, 90 min, 120 min, 180 min, 12 hours, 24 hours.
24 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Breath Hydrogen from baseline
Time Frame: 2 hours
Patients will be asked to exhale a full breath into a sample collection bag. The breath samples will be extracted and measured using the Quintron BreathTracker Analyzer at time points: baseline, 60 min, 120 min. This will be a marker of carbohydrate fermentation in the colon.
