GMO camp going to have a difficult time with this one, as it was a 1k person study

While the study is interesting, in part because strands of cfDNA has started being used as markers for tumors, there's no indication that some strand of DNA from GMO are more or less dangerous than cfDNA from non-GMO (although new DNA is of course possibly more dangerous than DNA we have evolved with).
Besides, the study reported the presence of chloroplast DNA, which are of course inside plants but have their own DNA.

The second study is more interesting and to the point, although I wasn't able to find a study on how much Cry we absorb with our diet.
