Alan Dangour laughed when I told him I had just read the fourth Huffington Post blog to attack his study on organic food. The report has created an immense fuss. As one of the bloggers said, the study, commissioned by the UK Food Standards Agency, has been “picked up by what seemed to be every news outlet on the planet”.

The study, published in the American Journal of Clinical Nutrition, found “no good evidence” that eating organic food “would be of benefit to individuals consuming a normal varied diet”.
