**Build a mental toolkit for evaluating health information.**
1. Check the source: is it a peer-reviewed study, a news article, an influencer, or a product website?
2. Assess the claim size: is it suggesting a small benefit in a specific context or a dramatic cure-all?
3. Look for conflict of interest: who benefits if this claim is believed?
4. Check whether the claim is supported by systematic reviews rather than single studies.
5. Give a final assessment: is this claim worth acting on, watching, or dismissing?
