Ever since a class I took in college, I've been skeptical about whether organic fruits and vegetables are better for you in any meaningful way. What happened in that class? The professor pointed out that the term "organic" does not mean that the produce was grown with no pesticides or herbicides; only that it was grown with non-man-made ones. But surely that's better than synthetic pesticides and herbicides? Maybe. Nature has produced some pretty toxic crap (think of all the plants out there that are poisonous to humans). It's not clear that being restricted to a subset of chemicals (i.e., ones approved for organic farming) will mean that organic food ends up covered with less harmful ones. Indeed, the best available evidence, summarized here, is that organic isn't necessarily better for you.
I think it's entirely appropriate to worry about the pesticide and herbicide levels in our food. But the organic label is at best a distraction because the distinction between man-made and natural chemicals is quite meaningless. At worst, it's harmful because it leads people to believe that they can avoid the negative impacts of chemicals by eating organic. What we really need is a way to know what was sprayed on the food we're eating and how much. Unfortunately, as long as people believe that "organic" = "healthy", that's unlikely to happen.
