How to read articles about health and healthcare

By Dr Alicia White
If you’ve just read a health-related headline that’s caused you to spit out your morning coffee (“Coffee causes cancer” usually does the trick) it’s always best to follow the Blitz slogan: “Keep Calm and Carry On”. On reading further you’ll often find the headline has left out something important, like “Injecting five rats with really highly concentrated coffee solution caused some changes in cells that might lead to tumours eventually. (Study funded by The Association of Tea Marketing)”.

The most important rule to remember: “Don’t automatically believe the headline”. It is there to draw you into buying the paper and reading the story. Would you read an article called “Coffee pretty unlikely to cause cancer, but you never know”? Probably not.

Before spraying your newspaper with coffee in the future, you need to interrogate the article to see what it says about the research it is reporting on. Bazian (the company I work for) has interrogated hundreds of articles for Behind The Headlines on NHS Choices, and we’ve developed the following questions to help you figure out which articles you’re going to believe, and which you’re not.



Does the article support its claims with scientific research?

If an article touts a treatment or a lifestyle factor that is supposed to prevent or cause a disease, but doesn’t give any information about the scientific research behind it, or refers to research that has yet to be published, then treat it with caution. A lot of caution, like balling the article up and throwing it in the (recycling) bin.
