Organic Food: Not Healthier than Regular?

Organic food isn't healthier than processed food, item to item. It's just more expensive. That's what CNN says. From the article:

Researchers looked at 50,000 studies conducted over 50 years — and found no significant differences in the foods. They focused on a wide range of crops and livestock raised and marketed under organic standards.

I suppose that could mean one of a few things:

1. This entire study is just propaganda from Big Food, carefully calibrated as a response to Food Inc. Having worked in PR, this wouldn't surprise me.
   
2. The study is legit, but ignores the environmental impacts of non-organic foods.
   
3. The study is legit, and we should stop spending nearly 2x on organic foods.
   

Maybe there's a compromise: buy from farmer's markets/local producers when you can, but go to the largemart foodcorp store when you can't. Who knows. How do you buy groceries, dear blog reader?
