That's true about just going with any random food on that website just because it's on a list...but it's still a good starting point to see what is available and to compare foods across the board.
This thread has some good resources for China ingredients and an interesting Customer service test.

Definitely contact the company to get more information on CURRENT ingredient sourcing and manufacturing practices among other factors as these things are always subject to changing. I can't say much about Innova since I haven't fed it too much or contacted the company but before you try to transition to Innova, I'd shoot Natura Pet an email to get more info on their ingredients and practices and whatnot.
