The future of flavonoid research.
There are insufficient data to provide conclusive evidence on the health effects of most flavonoid subclasses. Future research of polyphenol bioactivity requires a more complete understanding of their intake, bioavailability and metabolism. The following summarises the limitations of polyphenol research as described across various reviews throughout the literature and presents the key requirements for future research. These include establishing the effects of processing, bioavailability and metabolism, developing physiologically appropriate in vitro models, standard methods of analysis and appropriate clinical biomarkers. The future of flavonoid research will undoubtedly depend upon the resolve of these issues, and although the field has shown continuous progress for many years, progress will likely slow if these challenges are not met.
