Organic onions healthier than conventional (online)

Organic onions have more antioxidants than conventional ones

A recent study in Ireland found more antioxidant activity and higher flavonol content in organic onions compared to conventionally grown ones. While it’s a relatively narrow finding, it’s significant because the study lasted six years, which is reported as the longest-running study of its kind. The differences in antioxidant activity and flavonol content were found to be due to different soil managemnet practices used in organic farming, such as organic fertilizer, crop rotation, and cover crop, rather than a lack of pesticide/herbicide use.
