I've never seen any research that even suggests USDA organic to be any more nutritious than standard produce. It is certainly marketed that way, but I don't need to go off on marketers here.
Commenting independently on the research, Lord Krebs, former chairman of the UK's Food Standards Agency (FSA) and now an academic at Oxford, told The Times that higher flavonoid levels do not necessarily mean that organic food is healthier.
"This depends on the relevance of the differences to the human body. Tomato ketchup has higher levels of lycopene [a strong antioxidant] than either organic or conventional tomatoes. So if you wanted lots of lycopene you should eat tomato ketchup," he said.
A recent review, published in the journal Nutrition Bulletin and authored by Claire Williamson from the British Nutrition Foundation, stated that the overall body of science does not support the view that organic food is more nutritious than conventionally grown food.
"Organic farming represents a sustainable method of agriculture that avoids the use of artificial fertilisers and pesticides and makes use of crop rotation and good animal husbandry to control pests and diseases," wrote Williamson. "From a nutritional perspective, there is currently not enough evidence to recommend organic foods over conventionally produced foods."
There is a good reason why the 7th day Adventists at Loma Linda are one of the healthiest populations in the world--they grow their own food and practice healthy soil maintenance.
