Yeah its also incredibly adaptive. You hardly know any specific interaction with anything you come into contact with on a daily basis, doesn't mean you hide in a bubble your whole life. The body deals with things as they come at it, thank evolution or we would have been extinct long ago. Every time our species moved to a new region we were introduced to completely new foods. GMOs are tiny variants of what we are already used to. I'm sure we'll do fine.

I'm curious to know though. What specific complexity are you worried about disrupting.
