Another comment has already pointed out that until we see the underlying study we can't be sure that this press release is really important. I note that the claim "In the largest study of its kind, an international team of experts led by Newcastle University, UK, has shown that organic crops and crop-based foods are up to 69% higher in a number of key antioxidants than conventionally-grown crops" doesn't tell us anything important unless it can be shown that those "key antioxidants" are genuinely important for human health, and despite some hand-waving in the press release, there is no epidemiological evidence at all that the presence or absence of particular antioxidants in foodstuffs is associated with better health in human beings.
