This is actually very interesting. I have debated with scientists before who were adamant that DNA was destroyed un the digestive tract, therefore we only absorbed proteins, minerals etc directly from food into the bloodstream.
The point this article la making is that if it's now proven that DNA from all food makes it into the bloodstream, what are the implications off genetically modified DNA making it through? It has to be understood that non gmo DNA would be relatively harmless as the human body has been exposed to whatever is in out food for as long as have humankind had been eating it.
However, GMO DNA comes from places like scorpions in tomatoes and scorpions are not usually on our menu.
The next study that needs to happen in one on whether the DNA passes into our bloodstream actually does anything, or whether it it's simply inert.

It's pretty scary actually.
I think I'll stop eating carrots. All that carrot DNA might make me turn into one.
It is certainly possible that bastardised DNA sequences that our bodies are not use could react badly with our bodies. The presumption use to be that this stuff did not pass into our blood stream. We now know it does..
BrothermanHey can I ask you if you know that is, what is the significance of all of this, apparently this has happened since people ate things, knowing this what does it really change or how does this help us other then some professor can tell some smart ass kid, "thats why smartass."
I can't come up with any immediate significance but I'm not a geneticist. But it would seem to fall into the category of "Wow. Look at that. I did not know that." at this point.
PhageIn any case, trying to relate it to GM is pretty ridiculous since the study has nothing to do with GM.
On the one hand the anti-GM crowd says that gene transfer is risky business and unnatural while with the other hand pointing to studies which show that inter-species gene transfer does indeed occur naturally. It would seem that if anything artificial gene-splicing would be safer since it is known exactly what genes are being transferred. With nature it's a crap shoot.
Some people can't eat peanuts or shellfish, GMO will have its share of problems no doubt,
I know I'm talking allergies rather than something more sinister I think this will be a future problem
for GMO, or anyone who does react badly (if it is something more sinister) they'll be placed
under the allergy banner to hide the facts.

Yes it does happen. The first time I heard about it was in reference to rice DNA.

It doesn't really change anything. As other people mention, we've been eating everything for millions of years and it also happened before. Since macropinocytosis (Bulk uptake of stuff from the stomach if you will) happens in the endomembrane system, it was just a matter of time before this was discovered. And yes, I am a geneticist.
One of the arguments used by GMO scientists is - their is no risk the DNA is destroyed by the digestive system. What a surprise that they were wrong, I was reporting this eight years ago.
It has been shown that the novel gene in a GMO is more likely to be taken up by another organism, it has been shown that GMO's have multiple unintended insertions of the novel gene into the organisms genome. The method of gene insertion uses viral materials and bacteria which also raises questions on whether these genes can be taken up by the human genome.
We don't know what is happening the testing has not been done - you people are saying this is irrelevant - really?

Hell I quit eating carrots years ago when I discovered Sam Adams I'm glad to hear that you will also be boycotting them nasty little orange things!
