Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The impact of fiber intake on short chain fatty acid (SCFA) metabolism has not been studied in subjects suffering from COPD. The purpose of this study is to compare changes in SCFA metabolism after inulin vs. placebo intake in COPD patients to healthy matched controls. This protocol is an extension of a recent study about whole-body SCFA production rates in COPD patients. The investigators hypothesize that a short-term fiber supplementation increases SCFA production in COPD patients.
