In other words, there was no firm evidence that organic food was a healthier choice. Plants really don’t care. They take up the same nutrients in the same form regardless of the type of fertilizer used. When you peel or wash off produce, you remove most of the pesticides and other unwanted matter, and some organic or natural pesticides are actually more dangerous than synthetic ones. These facts negate any presumed mechanism by which organics would be healthier or safer.
Late addition from NBC News (October 22): "The nation’s pediatricians have weighed in on the issue for the first time, and they say that when it comes to nutritional value, organics are virtually indistinguishable from conventionally produced foods."
