Interaction between probiotics and polyphenol-rich fruit

ealth benefits of dietary polyphenols are mediated in

part by metabolites produced by intestinal microbiota.

Considering that select probiotic bacteria strains metabolize

polyphenols, we hypothesized that adding probiotics to

a polyphenol-enriched diet would improve the health

outcomes of polyphenol consumption. In separate studies,

we found that dietary co-supplementation with probiotics

and polyphenol-rich fruit reduced the health benefits

of either supplement alone. Polyphenol absorption,

measured by urine hippuric acid, was not impaired by co-

supplementation. Nor was probiotic viability reduced in

the combined vs. probiotic diet. Identifying reasons for the

interference requires further study of how probiotics affect

resident microbiota communities and metabolite output.
