Thanks. My understanding is also that most of the evidence in support of organic foods / grassfed meat is largely anecdotal for the most part. There might be very marginal discernable nutritional differences for minor things in some cases (like Omega-ratios and what have you), but I believe that biological data in support of the superiority in diet is largely absent / inconclusive. I'm not extremely well-versed in the topic but I did some cursory research not too long ago to try to find anything objective in support of how I "should" eat. That failed to produce anything scientific of substance.
My personal guess at this point is that a great deal of the weight behind a number of these things is largely conjecture.
