So is organic better or what? Not, according to the latest salvo in the debate. Last March a report from the Organic Trade Association in the US said that organic produce had on average a 25% nutritional advantage over the “normal” stuff. But now Prof. Joseph Rosen at Rutgers says in a report for the American Council on Science and Health that the previous study was flawed and the advantage disappears when you compare like with strictly like. That may well be, of course, but a recent paper shows that there are other benefits of going organic. The ecological footprint of organic Tuscan wine was found to be half that of a conventionally-produced tipple. No word on the relative health benefits.
