What we will and will not say

Read the editorial policy
  • No disease claims

    Nothing here treats, cures or prevents a condition. A post that says otherwise does not publish.

  • Every effect claim cites a study

    A link to PubMed, Cochrane or the journal, in the same article, so you can read it yourself.

  • Animal and test-tube results say so

    Most polyphenol research is not in people. Where it is not, the article tells you before the claim.
