 This research paper examined the potential benefits of consuming high levels of flavonoids on vascular health. It compared the performance of the metabolite fingerprint score, MFS, which uses a combination of metabolite markers to identify individuals with high or low flavonoid consumption, against other traditional methods. The MFS was found to be superior at distinguishing between high and low flavonoid consumers, suggesting it could be used to identify individuals with different levels of flavonoid consumption.
