‘Our review indicates there is currently no evidence to support the selection of organic over conventionally produced foods on the basis of nutritional superiority,’ said Alan Dangour of the London School's Public Health Intervention Research Unit. Surveying 50,000 studies conducted over 50 years, the authors focused on 55 that met their standards of scientific rigor.
The studies that led to the group's controversial conclusions covered a wide range of crops and livestock that are raised and marketed under organic standards. For 10 out of 13 food crops studied, the researchers found no significant differences. Where they did find differences, those were attributed to differences in fertilizer use (say, the use of nitrogen vs. phosphorus) and the ripeness level at which the crops were harvested. The authors judged the differences observed ‘unlikely’ to ‘provide any health benefit’ to
