Evidence-based health education

Editorial policy

Editorial and recommendation standards

These rules apply to every guide and product recommendation we publish.

How we weigh evidence

We prefer primary research, systematic reviews, and guidance from accountable public-health institutions. We describe limitations, conflicts, and uncertainty instead of flattening them into a verdict.

How we cite sources

Health guides identify their sources and distinguish what a source says from our interpretation. Material updates receive a new review date; changing a date alone does not make an article current.

Who writes and reviews

Joy Health is an educational publisher, not a medical practice. We do not assert clinical authority, and we identify qualified reviewers by name and credentials only when they actually participated.

How we recommend products

Products are compared using stated criteria, practical tradeoffs, and the available evidence.

How we correct errors

Substantive errors are corrected promptly. When a correction changes the meaning of a guide, we note what changed rather than silently rewriting the record.

In practice

Every guide lists the sources it used.
