There is a lot of indications that GMO crops are much more likely to "trigger" food intolerabilities then older crops. Through this seems to be an issue about them being further distant from what humans did eat for over a thousand years then about GMO being bad per-se. I.e. this also seem to apply (but less so) to crops which used more tradition (modern speed up) methods of cultivating crop variants.
