Bad Influence: How the Internet Hijacked Our Health

“This superb book is an essential guide to the wild world of internet health.” —Chris van Tulleken, author of Ultra-Processed People

When did we start trusting influencers over doctors?

As hospital wait times grow ever longer and some patients are priced out of medical care altogether, influencers have filled the gap. From doctors promoting new therapies, to entrepreneurs selling solutions, these self-styled experts glow with good health and guarantee results.

But they are not familiar with our medical history. They don’t owe us a duty of care. And they’re rarely either qualified or impartial. So why do we trust them?
