I am writing a research paper and trying to prove in it that GM foods have a negative impact on human health. I know this has not been completely proven, however, I also know that there have been attempts in trying to prove this. I also understand that the research done on this subject did not prove that GM foods do not have a negative effect on human health. Therefore, would like to discover the possibilities. I'm having difficulty finding facts that would help me support my argument.
I'll appreciate any kind of input that anyone has.
Thank you.

At first glance at this symbol on the back of somebody's car I thought it was a pro-evolution mockery of the christian fish sign. But then I realized this might not be the case because the symbol could mean that darwin is being likened to a primitive inferior creature.
