Over the years, Goldacre has taken on everyone from sloppy journalists to pharmaceutical executives, vitamin proprietors, and disingenuous academics. He has illuminated the evidence, and lack thereof, behind detox footbaths, homeopathy, and ear candling.

His writing has changed policy and informed the public at a time when few in the media stand up for science in health.
