I've only seen a report of one real study and that was over 10 years ago.
Other then that, it's just been biased, unsubstantiated gibberish from both camps.
The non-organic vegetables and fruit are "healthier", ie more robust. It makes sense that a more robust version of a cucumber would have more of the good stuff in it than its punier organic cousin.
Speaking as a professional horticulturist, your statement doesn't convince me at all.
Show me the controls. Show me the soil tests. Show me the data from the field trials. Show me results of the mass spectrometry, gas chromatography or whatever was used to assay the vitamin, mineral, bioflaviniod, etc. content of each species of vegetable tested.
Until I have trustworthy science on which to base an informed opinion, this debate has all the significance of a trial lawyer stating that gore won in 2000.
Shoot I don't care about it that much ;-)
I pick the veggies that look good and if both an organic veg and a modern tech veg look the same, then I buy the cheaper one. Works for me.
