I know a microbiology researcher who says the stuff we eat is far too clean. He's referring to excessive sanitation. But as far as food that has less artificial hormones and antibiotics, I can't see a downside.
If it's safe and it tastes good, I will eat it.
I recall a William Gibson book-- maybe it was Count Zero or Neuromancer-- where one of the characters meets an incredibly wealthy person for dinner. He's perplexed that the steak is so bland. It's explained to him that the steak is bland because it was made from a real cow that grazed in a real field on real grass, as opposed to an animal grown in a vat that was fed a diet of krill.
