An infographic titled The Trust Test, based on the WCRF TRUST Test, lists five steps (Too good to be true, Research-backed, Understood, Source quality, Think before you share) to help evaluate health information reliability, with icons and brief explanations.

The TRUST Test won’t tell you what to think. Instead, it helps you ask the right questions and approach health information more critically.

Whether you’re reading about supplements, nutrition, cancer prevention or general wellbeing, taking a moment to use the TRUST Test can help you make more informed decisions and avoid being misled by claims that sound convincing but aren’t supported by evidence.

The TRUST Test is a simple way to pause before acting on or sharing a health claim, and can be used by the public and health professionals.
