GM proponents who constantly drone on with untrue claims that the science has clearly demonstrated GMOs as safe were dealt yet another blow shortly before Thanksgiving this past year.
This is because yet another study has been published demonstrating the negative health effects of GMOs on the intestinal tract.
This study by Ibrahim and Okasha entitled “Effect of genetically modified corn on the jejunal mucosa of adult male albino rat.,” and published in the journal Experimental and Toxicologic Pathology has demonstrated that rats fed GM Bt corn MON810 for only 90 days did indeed suffer rather serious damage to the surface mucous membranes of the jejunum – which is part of the small intestine.
The specific type of corn fed to the rats was MON810: Ajeeb YG. This is a GM version of Ajeeb, which is a local species of corn grown in Egypt. The GM version was created by Monsanto for the Egyptian market.
The rats who were fed the GM corn were given the MON810 corn as 30% of their diet. The control group was given the same amount of non-GMO corn.
In the group fed GM corn, the finger-like structures in the intestine known as villi that absorbs nutrients from food were clearly damaged. They were both distorted and flattened and some cells were even joined together.
The study includes images and shows photographs of the damage. There were also signs of inflammation around the areas of damage in the form of white blood cell infiltration. The mucosal glands were disturbed and blood vessels were congested. There was also an increased level of shedding of mucosal cells, higher rates of division of cells lining the mucosal glands and larger numbers of mucous secreting goblet cells.
The damage to the GM-fed rats was so obvious, that the researchers concluded, “consumption of GM-corn profoundly alters the jejunal histological [microscopic] structure”
They also added that,
Results from the current study could show that in spite of the assuring reports on GM products, GM corn has profoundly altered the histological structure of the jejunal mucosa at many levels and revealed several alarming signs, as the proliferative and eroded hemorrhagic lesions in addition to several ultrastructural alterations described here for the first time for jejunum under GM corn influence.
The researchers also called for more research to be done in order to determine exactly how this strain of GM corn inflicted this type of damage on the intestinal system. Their suppositions include direct damage as a result of the Bt toxin or indirect damage as a result of gut bacteria disruption.
The limitations of the study include the fact that the control group was not given the Ajeeb non-GM variety and there was no analysis in terms of the possibility of the presence of pesticide residues and other contaminants. Still, the findings of this new study are extremely significant in that they demonstrate that at best, GM MON810: Ajeeb YG causes damage to the intestinal system.
However, the results do seem to indicate that it is the process of genetic modification that is the cause of this damage. This is not the only study of its kind.
