The American Academy of Environmental Medical Sciences issued a report saying: "Some animal experiments show that eating genetically modified foods has the risk of serious damage to health." Regarding the invasion principle of transgene, the research pointed out that the gene inserted into transgenic soybean will be transferred to the DNA of bacteria living in our intestines and continue to play a role. This means that after eating, although we don't eat genetically modified food, we will still produce potentially harmful gene proteins in our bodies. "To put it more thoroughly, eating genetically modified corn will turn the bacteria in our intestines into living pesticide factories, possibly until we die."

Rumors:

First of all, it should be noted that the American Society of Environmental Medicine cited in the article is not on the list of academic organizations recognized by the authoritative American Medical Specialist Committee.

Secondly, there is indeed such an American organization that has published a report (preparing to go on a diet in another corner). The results show that Mon 8 10 has a restrictive effect on small intentions of rats. The cellular level was compared with the well-documented toxicity observed in suspicious inserts. "No suggestion is not bad" and "negligible" have shown that the safety of MON8 10 is no different from that of non-transgenic corn. This is because the citation deliberately exaggerates the normal fluctuation of experimental observation statistics as a significant difference and distorts the conclusion of the author of the research paper.

The second document is about insect-resistant corn, but the conclusion is as follows: "In short, although the results obtained from this study show that rats fed with Bt corn have slight histopathological and biochemical effects, transgenic Bt corn has not caused serious health problems to rats after three generations of long-term $ TERM consumption." The bold part should be clear. The results showed that long-term consumption of genetically modified corn did not cause serious health problems to mice. )

The third document only observed the changes of some indicators, and did not say that the changes of these indicators would damage the immune system, but suggested that these factors should be considered in the safety evaluation of genetically modified crops. "Although the significance of these data remains to be clarified to determine whether these changes reflect obvious immune dysfunction, these results show that it is important to consider the response of intestinal and peripheral immunity to the whole genetically modified crop and age in the safety assessment of genetically modified organisms."

Obviously, this report and the statement that "the United States claims that genetically modified organisms are toxic" exaggerate and distort the research results of the original paper. More interestingly, the author's "brain tonic" and "transgenic infringement principle" are even more alarmist.

First of all, the report (https://www.aaemonline.org/gmo.php) did not mention this violation principle, and no formal biology textbook said that there was such a principle. Secondly, this so-called "principle" is ridiculous. The gene inserted into genetically modified soybeans will be transferred to the DNA of bacteria living in our intestines and continue to play a role! The author did not give any specific experimental basis and data. You know, human gastrointestinal bacteria have lived and evolved with humans for millions of years before transgenic, and there is no sudden gene transfer between bacteria today. The transgene we use has existed in nature for a long time. Genes and gene products are borrowed, not invented out of thin air. Even if it is transferred in bacteria, it must go through natural selection, and bacteria will not accept useless genetic inheritance. Moreover, these genes and products have no influence on human beings. This means that even if we don't eat genetically modified foods, we will still produce potentially harmful gene proteins in our bodies. What does it mean to eat genetically modified food and then call it "although I don't eat genetically modified food"? Did you eat or not?

Take another ten thousand steps. Why is the expression of insect-resistant protein by bacteria harmful to human body? Whether insect-resistant protein is harmful to human body is related to its physical and chemical properties. It is harmful to express insect-resistant protein in crops, but is it harmful to express the same protein in bacteria? The safety of transgenic genes and their protein products can be easily evaluated by experiments. It's a daily job, not a scientific problem. Now it has been approved for marketing, which shows that these genetically modified crops are safe. The author has no scientific basis from the most basic support point (the safety of insect-resistant proteins) to the absurd "infringement principle of genetically modified organisms", but he continues to demonize genetically modified organisms by concocting rumors under the pretext of a report from a foreign institution, and at the same time incites the public to distrust government supervision.

What we want to emphasize is that the normative research recognized by the scientific community unanimously shows that genetically modified crops are safe to eat. In fact, similar research under the guise of rumor articles has long been conclusive. For example, in 2008, Japanese scientists fed transgenic soybeans to F344 rats 104 weeks, which showed that transgene had no effect on rats. In 20 14, Yang Xiaoguang Research Group published the animal experiment results of long-term edible safety of transgenic insect-resistant rice, which also showed that it was safe to eat transgenic rice.

Previously, in order to calm the public debate, the French and European authorities decided to start three research projects, namely "Risk Assessment and Evidence Exchange of Genetically Modified Organisms" funded by the European Union. GRACE) and the two-year safety test of transgenic plants (G-TWIST), as well as the French-funded project "Transgenic feeding for more than 90 days" (GMO 90+, 01.2014-12.3806). Now six years have passed, and all three studies have been completed. The cost is * * *150,000 euros, which is about1170,000 RMB. The published research results show that the transgenic corn varieties involved in the experiment have not caused any negative effects in animal experiments, nor have any potential risks been found in genetically modified foods, nor have any toxicological effects related to chronic toxicity and carcinogenicity been found. Related research results have been published in several journals and recent reports of the French Association of Plant Biotechnology.
