How we read a health headline
Most scary or miraculous health claims are not lies. They are real findings stretched past what they can carry. We try to put them back in proportion.
- What kind of evidence is it?
- A lab dish, a mouse, a survey of eating habits and a randomized trial in people answer very different questions.
- Risk compared to what?
- "Doubles your risk" can mean a big change or a tiny one. The starting point matters more than the multiplier.
- Does it fit the wider picture?
- One result rarely overturns a large, consistent body of research. We look at where the evidence points overall.
- Who is it true for?
- Advice that helps one group can be irrelevant, or wrong, for another. We say who a finding applies to.
