Editorial policy
These are not aspirations. Each one is checked by software before an article can be published, and an article that fails a check is sent back.
We do not make disease claims
Nothing on this site says a food or compound treats, cures, prevents, reverses or heals a condition. Where the evidence supports it, we say a food is associated with an outcome, or may help. Where it does not, we say that too.
Every effect claim links a primary source
If an article says something lowers, raises, improves or protects, it links the study or systematic review that showed it, on PubMed, a DOI, the Cochrane Library or the journal itself. We read the paper, not the press release.
Animal and test-tube evidence is labelled
Most polyphenol research is in cells or in mice. When an article relies on that kind of evidence, it says so in plain words, and it says whether the result has been seen in people.
Reviews say how we got the product
Every review states whether we bought the product, were sent it for free, or have not tested it. A review that does not say cannot be published.
Supplement articles tell you to talk to a doctor
Supplements carry dose and interaction risks that eating berries does not. Every supplement article says so and points you to a doctor or pharmacist.
Affiliate links are disclosed
Some links earn us a commission if you buy. Any article with such a link says so in the text. Rankings and recommendations are never for sale.
This is not medical advice
PolyphenolGuide is educational. It does not replace advice from a clinician who knows your history.
