GMO DNA passes into your blood
The biggest question is this: Does eating GMOs modify your DNA? The short answer is: Possibly. No one really knows.
GMOs are produced through horizontal gene transfer, which involves splicing genes from an external source (either another organism, or a synthetic gene engineered in a lab) into the genome of a living creature. This process is so new that it remains unclear if this horizontally transferred DNA might behave in ways different from traditional, “vertically transferred” DNA (that is, inherited from one’s ancestors).
Some bacteria have been shown to horizontally transfer DNA between species; it is unclear if this can occur among more complex organisms, as well. If so, there could be biological pathways in place allowing engineered DNA from GMOs to move into the human genome.
This concern remains mostly theoretical, but at least one study showed that DNA from GMOs can indeed leave your food and enter your bloodstream. Could it be taken up from there by some of your cells and incorporated into your genome?
A 2014 paper in PLOS One analyzed the results of four prior independent studies on more than 1,000 human participants who had eaten GMO foods, including derivatives such as high-fructose corn syrup, soy protein, or meat from animals fed GMOs. The researchers found that DNA fragments derived from GMO plants were indeed found in the bloodstream, rather than being broken down as GMO companies claim.
“In one of the blood samples the relative concentration of plant DNA is higher than the human DNA,” the researchers wrote.
The DNA found was “cell-free DNA,” which floats outside of cells and is not known to play any physiological role. Thus, the study does not prove that the human genome is being modified by GMOs – but it does refute a main claim of GMO proponents, and raises some important concerns.
