I think much of it is a sham, but some of it has some validity. As an example, you can give me two apples, one organic and the other bathed in chemicals and I couldn't tell the difference - except that there would be a good chance the "organic" one would have a worm or two.
But, when it comes to meat, I can easily tell the difference. IMHO, grass fed, free ranging beef tastes MUCH better than the grocery-store bought grain-fed, pen-raised beef. There's really no comparison. And, I would venture to guess that most people, in a blind taste test, would pick the former and not the latter.
The premise applies to natural, line-caught salmon vs. pen-raised salmon fed with grain and "dyed" red (the grain pellets don't have enough of the right kinds of minerals and vitamins to actually produce red salmon meat). And the "happy pig" organically raised pigs produce a much tastier meat than the other kinds of "industrialized" farming pigs. FWIW.
I agree about organic meats usually tasting better, though free range chicken is a little too gamey for me. My previous posts refered just to fruits and veggies. And, IMO, the organic fruits and veggies look sickly and underdeveloped compared to non-organic choices.
A moot point, because neither of us will spend the money to test you, but I would venture to guess that you, in a series of properly-administered, double-blind taste tests, could not consistently, repeatedly differentiate between identically-prepared grass fed, free ranging beef and grocery-store bought grain-fed, pen-raised beef. Like I said, there’ll be no comparison, because neither of us is willing to pay for the testing, but, really...
