DNA From Genetically Modified Crops Can Be Transferred Into Humans Who Eat Them
In a new study published in the peer reviewed Public Library of Science (PLOS), researchers emphasize that there is sufficient evidence that meal-derived DNA fragments carry complete genes that can enter into the human circulation system through an unknown mechanism.(plosone.org)
In one of the blood samples the relative concentration of plant DNA is higher than the human DNA. The study was based on the analysis of over 1000 human samples from four independent studies. PLOS is an open access, well respected peer-reviewed scientific journal that covers primary research from disciplines within science and medicine. It’s great to see this study published in it, confirming what many have been suspected for years.
“Our bloodstream is considered to be an environment well separated from the outside world and the digestive tract. According to the standard paradigm large macromolecules consumed with food cannot pass directly to the circulatory system. During digestion proteins and DNA are thought to be degraded into small constituents, amino acids and nucleic acids, respectively, and then absorbed by a complex active process and distributed to various parts of the body through the circulation system. Here, based on the analysis of over 1000 human samples from four independent studies, we report evidence that meal-derived DNA fragments which are large enough to carry complete genes can avoid degradation and through an unknown mechanism enter the human circulation system. In one of the blood samples the relative concentration of plant DNA is higher than the human DNA. The plant DNA concentration shows a surprisingly precise log-normal distribution in the plasma samples while non-plasma (cord blood) control sample was found to be free of plant DNA.” (plosone.org)
This still doesn’t mean that GMOs can enter into our cells, but given the fact GMOs have been linked to cancer (later in this article) it is safe to assume it is indeed a possibility. The bottom line is that we don’t know, and this study demonstrates another cause for concern.
