I agree that less processed foods are going to be best. I see "organic" as top of the line in the less processed arena. For example, an apple wouldn't have pesticides and loads of other similar crap in it. Or at the very worst case scenario, due to some kind of cross contamination... it should have less of it.
I think most food companies and studies will try to convince you there is nothing wrong with pesticides, fertilizer, and all the other loads of processing they do. But they want to continue to sell you cheap crap and get away with it. For instance, consider meat with "fillers", or muffins with blue dye # xyz versus just using real blueberries.
I grew up on a farm and let me tell you there is a big difference in doing things with a natural/organic approach. In fact to me the meat even tastes different (better), produce is smaller (apples aren't the size of a softball), milk and eggs taste much better as well (2% taste like whole, eggs are not runny and gross like snot).
My logic was just a simple idea based on the old saying you are what you eat. I figured if you give a cow rBGH, fina, antibiotics, and loads of other crap, then you eat the cow... it can't be good. LOL 
No doubt.
Organic is superior for the reasons mentioned above, as well as others.
I just think that the benefits have approached "fad-status" over the years, becoming at least a tad overexaggerated.
Ashley Mullins, R.D., L.D., CNSC, is a registered dietitian at Baylor All Saints Medical Center.
She has gone on record saying: “From a nutrition standpoint, there isn’t enough research to show that organic foods are more nutritious than regular foods. The levels of pesticides currently used haven’t been found to be harmful. Of course, there may be other benefits to buying organic, such as it being more environmentally friendly and, in some cases, fresher.”
Currently, neither the FDA nor the American Academy of Pediatrics claims that organic foods are more nutritious. "To a pediatrician, making sure your baby receives a balanced diet is what is preferable," notes pediatrician Steven Abelowitz, M.D., medical director of Coastal Kids Pediatric Group in Newport Beach and Laguna Niguel, California.
Regardless of the above facts and claims, these fruits and veggies consistently top the list for their pesticide load, and it
IS advisable to consume their organic counterparts when possible:
1. Peaches
2. Apples
3. Sweet bell peppers
4. Celery
5. Nectarines
6. Strawberries
7. Cherries
8. Lettuce
9. Imported grapes
10. Pears
11. Spinach
12. Potatoes
