Since 2003 Dr Ben Gold acre has been exposing dodgy medical data in his popular Guardian column. In this eye-opening book he takes on the MMR hoax and misleading cosmetics ads; acupuncture and homeopathy; vitamins and mankind's vexed relationship with all manner of toxins. Along the way; the self-confessed Johnny Ball cum Witchfinder General performs a successful detox on a Barbie doll; sees his dead cat become a certified nutritionist and probes the supposed medical qualifications of Dr Gillian Keith.
