Except part of the reason you have mostly packaged, mass produced crap is because of your own regulations which specifically try to block the US market to protect your home markets.
That's besides the point though, you said US food isn't as healthy as EU food. You didn't say "imported, mass produced stuff isn't as healthy as fresh EU produce and meat". I was simply saying that you are getting a very skewed perception of US food if you are only comparing against imported US food.
US food in the US is generally high quality.
