Are GMOs safe to eat?

A minority of scientists still insist, however, that more research is needed before GM foods can be definitively considered safe. After all, genetic engineering isn't exactly like traditional breeding, and it may have downstream effects scientists haven't fully studied.

For example, in a dissent to that AAAS statement, 21 researchersargued that increased herbicide use — which can occur with crops engineered to be resistant to Roundup — might have health effects we don't yet know about. (That said, many "conventional" crops also require plenty of pesticides. This varies from crop to crop, and simply calling something "GMO" doesn't necessarily tell you all you need to know.)
