Before that, there were rumors on the Internet that genetically modified food had great harm to human body, so many people were very scared when talking about genetically modified food. The authoritative academic organization China Agricultural Biotechnology society today released the truth of the top ten rumors of genetically modified food in Beijing. Follow Xiaobian to find out the truth you don't know about genetically modified food.
There are many false messages on the Internet, such as "the fruit of the virgin is genetically modified" and "the Americans never eat genetically modified". Even if the authorities repeatedly refute the rumors, they fail to stop the spread of the rumors.
Rumor 1: Americans don't eat genetically modified food and sell it to China
Truth: more than 75% of food on the U.S. market contains genetically modified ingredients.
The United States is a big country in the research and development of genetically modified technology, as well as in the production and consumption of genetically modified food. According to incomplete statistics, there are more than 3000 kinds and brands of genetically modified foods from plants such as soybean, corn, rape, tomato and papaya produced and sold in the United States, and more than 5000 kinds of foods from genetically modified microorganisms such as rennet.
Myth 2: genetically modified lead to infertility of college students in Guangxi
Truth: the infertility of Guangxi university students has nothing to do with transgene.
The theory of semen abnormality of college students in Guangxi comes from the investigation report on sexual health of college students in Guangxi, which was put forward by the First Affiliated Hospital of Guangxi Medical University on the basis of investigation and research. In the report, the researchers did not put forward the view that semen abnormality is related to transgene, but listed the factors such as environmental pollution, long-term Internet access and other unhealthy living habits.

Myth 3: genetically modified soybeans destroy agriculture in Argentina
Truth: Argentina is not a 'genetically modified country'. Because of the use of genetically modified technology, Argentina has become a global agricultural exporter, which has brought real benefits to farmers.
Argentina is one of the first countries in the world to adopt genetically modified crops. In 2016, Argentina remained the world's third largest producer of genetically modified crops, second only to the United States and Brazil, accounting for 13% of the world's planted area. The country has planted 23.82 million hectares of genetically modified crops, including 18.7 million hectares of genetically modified soybeans, 4.74 million hectares of genetically modified corn and 380000 hectares of genetically modified cotton.
Myth 4: transgenic mice reduce and sows abort
Truth: mouse reduction, sow abortion and other phenomena are not related to transgene.
On September 21, 2010, the International Herald Herald reported that "the cultivation of" Xianyu 335 & rsquo; corn in Shanxi, Jilin and other regions led to the decrease of mice and the abortion of sows ". The Ministry of science and technology and the Ministry of agriculture respectively organize experts from different departments and specialties to form an investigation team to conduct on-the-spot investigation. According to the survey, 'Xianyu 335' is not a genetically modified variety. No genetically modified corn is planted in Shanxi, Jilin and other places. The phenomenon of mouse decrease and sow abortion is not related to the transgene, which is a false report. This report of the International Herald was rated as "top 10 scientific rumors in 2010" by the Beijing News. (this article is exclusively compiled by WYH, editor of sihai.com.

Myth 5: genetically modified food affects future generations
Truth: modern science has not found a case of integration of genetic material transmitted through food into human genetic material. It is alarmist to say that eating genetically modified food affects future generations.
Food from plants and animals has a history of more than ten thousand years. These natural foods also contain all kinds of genes. From a biological point of view, the exogenous genes of genetically modified food are digested and absorbed by the human body just like the genes contained in ordinary food. It is impossible to change human genetic characteristics by eating genetically modified food.
In fact, even the most traditional animal and plant food that people often eat contains thousands of genes. It is impossible and unnecessary to worry that the genes from animals, plants and microorganisms in the food will change human genes and pass them on to future generations.
Rumor 6: at present, the shengnv fruit, purple sweet potato and colored pepper sold on the market are all genetically modified varieties
Truth: at present, the shengnv fruit, purple sweet potato and color pepper sold in the market of China are not genetically modified varieties.
Plants are the precious wealth that nature gives to human beings. In the long-term farming practice, human beings cultivate and domesticate wild plants, thus forming rich crop types. All the saint fruit, purple sweet potato and color pepper in the market of our country are naturally evolved and artificially selected varieties.
Transgenic products can be divided into two categories: one is the transgenic insect resistant cotton and the transgenic virus resistant papaya planted and produced by our country; the other is the transgenic soybean, corn, rape, beet and cotton imported from abroad, which are mainly used as processing materials.

Myth 7: genetically modified food can cause cancer and infertility
Truth: genetically modified products approved for marketing through scientific evaluation are safe.
In order to ensure the safety of genetically modified products, the international Codex Alimentarius Commission, the food and Agriculture Organization of the United Nations, the World Health Organization and so on have formulated a series of safety evaluation standards for genetically modified organisms, which have become the globally recognized evaluation criteria. According to these evaluation criteria, countries have formulated corresponding evaluation norms and standards.
In terms of scientific research, many international professional organizations have reached authoritative conclusions on the safety of genetically modified products, and the genetically modified products approved for marketing are safe. From the perspective of production and consumption practice, more than 30 billion mu of GM crops have been planted commercially in the past 20 years, and no confirmed GM food safety incidents have been found. Therefore, the transgenic products that have been evaluated by scientists and approved by the government are safe.
Myth 8: insect resistant transgenic crops will die if eaten, which is also harmful to human body
Truth: insect resistant transgenic crops are harmless to humans.
Bt protein in insect resistant transgenic crops is a highly specific insecticidal protein, which can only bind to the specific receptor of intestinal epithelial cells of Lepidoptera pests such as cotton bollworm, causing intestinal perforation and death of pests, while other insects, mammals and human intestinal cells do not have the binding site of Bt protein, so it will not cause harm to other insects and mammals, not to mention affect them To human health.
In addition, it has been 100 years since the discovery of Bt protein and 70 years since BT preparation has been used as a bio insecticide safely.

Myth 9: transgenic crops do not increase production and have no effect on production
Truth: the effect of genetically modified crops is objective.
At present, the widely commercialized transgenic crops do not take increasing production as the direct purpose. The transgenic crops with higher yield and other better characteristics are the research and development direction of the next generation of transgenic crops.
The yield increase of agriculture is affected by many factors. Transgenic insect resistant and herbicide resistant varieties can reduce the harm of pests and weeds, reduce the loss of yield, accelerate the popularization of cultivation technology of less tillage and no tillage, and actually have the effect of yield increase. For example, Brazil, Argentina and other countries have greatly increased their yield after planting genetically modified soybeans; South Africa has doubled its per unit yield after promoting the planting of genetically modified insect resistant corn, from a corn importing country to an exporting country; India has also changed from a cotton importing country to an exporting country after introducing genetically modified insect resistant cotton.
Myth 10: planting GM herbicide resistant crops will produce "super weeds"
Truth: GM herbicide resistant crops will not become uncontrollable 'super weeds'.
In 1995, a few rape plants were found in the rape field of Canada, which can resist 1-3 herbicides, so it is called "super weed". In fact, this kind of rape can be killed completely after spraying another herbicide 2,4-D. In fact, "super weeds" is only a figurative metaphor, and there is no evidence to prove the existence of "super weeds".
