Bad Influence

'This superb book is an essential guide to the wild world of internet health – a series of cautionary tales, brilliantly told, about the perils of health influencers and the messages they peddle.' —Chris van Tulleken, author of Ultra-Processed People

'This book tackles one of the most important health issues of our time. It isbrilliant, thorough and vital. Empowering for anyone who has ever come across health information, stories, or advice online – which is pretty much all of us.' —Daniel M. Davis, Professor of Immunology at Imperial College London and author of Self Defence: A myth-busting guide to immune health

'Bad Influence arrives at a moment when fascination with health, longevity and "optimised living" has never been greater... With a reporter’s eye and a scientist’s precision, Deborah dissects the interventionist claims of the wellness industry and exposes the shaky evidence underpinning it. Her diagnosis is uncomfortable but urgent: that those selling us control over our health may, in fact, be the ones making us sick. Bad Influence is a must-read for anyone who has ever turned to the internet in search of better health – and a timely warning about the seductive power of bad influencers.' —Natasha Loder, Health Editor, Economist

'Eye-opening and concerning. This book will hopefully influence how you access healthcare information and maybe think twice before you make (often complex) decisions about your body based solely on your social media feed.' —John Tregoning, author of Live Forever?

'In a world where online medical opinions are fast and often dodgy, this is the perfect antidote.' —Prof. Kevin Fong
