Look for the original evidence
Ask whether a headline describes a study in people, animals or cells, and whether it reports an early finding or a well-established result. A press release may simplify details that matter for interpreting the claim.
Check the size and context
A relative percentage can sound dramatic even when the absolute difference is small. Study design, sample size, duration, comparison group and conflicts of interest all affect how much confidence a result deserves.
Separate evidence from advice
One study rarely settles a question. Look for consistent findings across high-quality research and guidance from credible health organizations. Avoid changing medication or treatment based on a headline or social post.
A thoughtful next step
Use this guide as a starting point, not a rigid rulebook. Consider your own circumstances, look for reliable sources, and seek qualified professional advice when a decision affects your health or safety.
