Check a published version of the guidance
Public records let you check which version of a piece of guidance was recorded and when. The records below apply to the specific content they identify.
How the check works
We create a digital fingerprint from the guidance. Changing the content changes its fingerprint.
For content with a public record, we record that fingerprint through the Hedera Consensus Service, which provides a public timestamp. We can then compare the content's fingerprint with the one recorded earlier.
A match confirms that the version being checked matches the recorded fingerprint. Scientific accuracy, external expert review, and health benefits require separate evidence.
Published records
Each row identifies a content version, its publication date, a link to the public record, and the result of the latest recorded check.
The list covers the records available here. It does not establish that every recommendation has a public record.
What the check result means
- Match confirmed: The fingerprints matched at the latest recorded check.
- Does not match: The fingerprints differed at the latest recorded check.
- Not checked yet: No comparison result is available.
These results concern the content version. For an explanation of a published change, visit Updates & Corrections.
