No, "science" has not confirmed that GMOs are safe to eat

First, and most importantly, the NAS doesn't hold an "umbrella" view on the safety of GMOs. Along with many other international bodies, it recognises that such a view is untenable, given that the GM process can give rise to different and unpredictable effects in each case. The committee points out that it has received "impassioned requests" to give the public a simple, general, authoritative answer about GM crops, but that given the complexity of GMO issues, it did not see that as appropriate. Following that, in a 400-page document, the committee develops its view on the issue. That view is undoubtedly more favourable to the use of GMOs in agriculture than that of most environmental groups – but it is also much more conservative than that of many GMO promoters (including El País). Far from stating that "science has confirmed that GMOs are safe", the report could be more accurately summarised as stating, "There’s a lot that we don’t know, which isn’t surprising, because no one is looking."
