An upcoming article in the Journal of Agricultural and Food Chemistry says that apples grown organically have a 15 per cent higher antioxidant capacity than apples grown conventionally according to a study from the Federal Research Institute of Nutrition and Food in Karlsruhe, Germany. 

The researchers compared the polyphenol content and antioxidant capacity of Golden Delicious apples grown under organic and conventional conditions over a three year period (2004-2006). "In the present study the organically produced apples displayed a higher phytochemical concentration and a higher antioxidant capacity than conventionally produced apples," wrote Bernard Watzl, who led the study.
