Courtney Swan, integrative nutritionist about GMO crops

"I would say I think the biggest concern is that the, well some of these crops already have a pesticide in them, so there's a certain crop called BT corn and it has a BT gene in there that is known, the mechanism is that when the insects eat this corn it makes their stomachs explode. And what I think is really interesting about this is that what it's doing is it's creating holes in the stomach lining of the bugs.
And something that Americans are dealing with right now at really high rates is something called leaky gut syndrome and that means that we're getting holes in the lining of our intestines. And what I find very strange is why did we think that this would affect insects and not affect humans?"
