Hi, Dash.
I think we mention antibiotic resistance experiments more than dietary experiments, and that you are just fixating on nylon-eating bacteria.
And, I'd like it on the record that I consider the argument form, "you can't demonstrate it, except when it's easy to demonstrate," to be extraordinarily weak.
