Summary

There is extensive pre-clinical evidence for potential health effects of blueberries. These are related, but not exclusively due to their high polyphenol content. This translational, clinical, randomized, cross-over, double-blind, placebo-controlled study will investigate the effects of blueberries in freeze-dried powder form on gastrointestinal and extra-gastrointestinal symptoms and function, as well as specific potential underlying mechanisms, in patients with the overlapping functional gastrointestinal disorders, irritable bowel syndrome and functional dyspepsia.
