How is GE ingredients harmful?

Question

How is Genetically engineered food ingredients harmful? Thanks.

Answer 1

They aren't.  Genetic engineering has been going on since the dawn of agriculture, and without it ninety percent of the world's population would starve to death.  Modern efforts simply speed up processes that nature has been doing for a billion years.

Answer 2

It may be harmful because it's a big unknown.  They have only been produced for a couple decades now, and there is very little research done on them except by the companies themselves, which are obviously going to say they are safe.  So  it's really far too early to tell if there are any adverse effects or not.
