Last year I visited Ben Goldacre in his secret offshore nerdbase to talk about science. While there we set up the famous Barbie Detox experiment as described in his book Bad Science. In this short video Ben talks about why the bogus idea of detox is harmful not just for our bodies, but our understanding of health. Says Ben: "The answer, from the future king of England, to your health problems is a fucking magic potion. It's like something out of a fairy tale!"
