Its a possibility, the unnatural GMOS we are constantly consume could make the chance of mutation more likely, but I don't know. We were made to consume at least some natural foods, but nowadays most foods are loaded with chemicals, etc.
Could be.... but the problem is that any food is taken by the corporations who make JUNK food out of it - and that does affect cancer and autism rates. Hard to say what the basic DNA codes do to that finished JUNK.
But many heavy-duty scientists have come out supporting GMO's now.
There is no scientific evidence that suggests GMOs harm those who consume them. GMOs will be essential in feeding the world in a few years, there will not be enough food.
