Most of the studies done on GMOs are short term. We need at least 100 years to see the impact. Short term studies are not enough, however, food intolerance is on the rise and so is heart disease and diabetes, so what does that tell us?

Also, bacteria is developing resistance to antibiotics because it's in our food and we are over saturated with it.

There was a study that found antibiotics in mother's natural breast milk. Babies are ingesting antibiotics before they can make their own decisions, etc. Surely, that is going to have an impact as it's already showing its face.

Here is a good Ted talk on the issue:
