Despite the high human interindividual variability in response to (poly) phenol consumption,
the cause-and-effect relationship between some dietary (poly) phenols (flavanols and olive …

Ellagitannins (ETs) are a large group of bioactive compounds found in plant-source foods,
such as pomegranates, berries, and nuts. The consumption of ETs has often been …

Ellagitannins (ETs) and ellagic acid (EA) are dietary polyphenols poorly absorbed but
extensively metabolized by the human gut microbiota to produce different urolithins (Uros) …

We aimed to elucidate the gut bacteria that characterize the human urolithin metabotypes A
and B (UM-A and UM-B). We report here a new bacterium isolated from the feces of a …

Flavonoids are a biodiverse family of dietary compounds that have antioxidant, anti-
inflammatory, antiviral, and antibacterial cell protective profiles. They have received …

Tannins comprise a large group of polyphenols that can differ widely in chemical
composition and molecular weight. The use of tannins dates back to antiquity, but it is only in …

Urolithin (Uro) B is a natural compound produced by gut bacteria from ingested ellagitannins
(ETs) and ellagic acid (EA), complex polyphenols abundant in foods such as pomegranates …

The gut microbiota (GM) produces different polyphenol-derived metabolites, yielding high
interindividual variability and hampering consistent health effects. GM metabotypes …

Polyphenolic compounds have a variety of functions in plants including protecting them from
a range of abiotic and biotic stresses such as pathogenic infections, ionising radiation and …
