Do polyphenols enter the brain and does it matter? Some theoretical and practical considerations
Open accessAbstract
Although several epidemiological and intervention studies suggest that polyphenols (PPs) and PP-rich foods may improve memory and cognition in animals and humans, PPs' mode of action is only poorly understood. To help distinguish between the different modes of action that have been proposed for PPs, it is obviously important to know how much PPs can accumulate in the brain, if any at all. However, reliable data on PP uptake into the brain of animals are limited as many studies failed to report important control procedures during data acquisition. In this paper, we summarize published data on the penetration of PPs into animal brain and review some hypotheses to explain the biological basis of potentially health-beneficial effects of PPs to the brain. Finally, we highlight promising new approaches, especially those of a hormetic dose-response and gut microbiota-brain interaction, which may allow a better understanding of PPs' mode of action in animals and humans.

Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Some so-called antioxidant molecules (for example, polyphenols such as resveratrol or quercetin) are able to enter the brain to a limited extent85.”
From Oxidative stress, dysfunctional glucose metabolism and Alzheimer disease (2019) · cites this paper as [85]
Experimental — accuracy not yet measuredThe cited source says what the claim attributes to it.
In the citing paper
“One mechanism by which polyphenols could exert protective properties is by generation of a hormetic response to their use85–88.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
