What's amazing to me, is how these types of studies completely ignore varietal differences!!! For example..... They may go into "Whole foods"" and buy a basket full of "Organic" Tomatoes for the study, comparing it to "Conventional" tomatoes from somewhere like Krogers.

The thing is that merely being "Certified Organic" doesn't mean that fruits and produce aren't the same varieties that have been developed for conventional farming.

There are miles and miles of certified organic farming in the central valley of California. These farmers are growing the same varieties of produce, that were developed and chosen to ship, store, and ripen under storage well that their more conventional neighbors do.... The "Old time" varieties were always chosen for taste, and nutrition. Not how well they stored, or shipped without bruising. The conclusion here is that Certified Organic is not necessarily better. Look to heirloom, and open pollinated if you want better taste, and nutrition.
