What is your attitude towards genetically modified food? A few days ago, at the popular science forum held at the Shanghai Science and Technology Museum, three experts explained to the public such controversial foods. Experts point out that since the advent of GM foods, there has not been a single case that they are harmful to the human body. On the other hand, the public should have the right to know whether or not a certain food is "genetically modified". At present, the detection of genetically modified signs in China is very strict.
The so-called transgenic technology is to separate a gene from a donor organism and implant another receptor organism so that the latter has certain characteristics of the former. In the agricultural field, if insect-resistant genes are planted on crops, they will be able to withstand insect pests and reduce the use of pesticides. Academician Chen Xiaoya, dean of the Shanghai Academy of Science, Chinese Academy of Sciences, pointed out that, as a result, insect-resistant genetically modified crops not only increase production, but also reduce the amount of pesticides, which is beneficial to the human body.
Then, after the rice planted with certain insect-resistant genes is processed into rice, will that gene not harm people? In response, Lu Baorong, chairman of the International Institute of Biosafety Research and Professor Fudan University, said that insects and humans have very different pH and body structures. Insect-resistant genes will only play a “killer†character in insects, so that pests can't eat and die. "So far, there has been no case of GM foods affecting human health."
At the popular science forum, experts said that although there is no evidence that GM foods are harmful, the public should have the right to know whether or not a food contains genetically modified ingredients. According to Zhang Dabing, the distinguished professor of Shanghai Jiaotong University, China adopts the “0 threshold†mandatory labeling system, that is, as long as there is a little genetically modified ingredient in the product, it must be noted. In the United States, voluntary labeling with a 5% threshold, that is, if the genetically modified component does not exceed 5%, does not require labeling. Even if it exceeds 5%, it is up to the manufacturer to decide whether to label it. If you do not trust GM foods, you can make effective choices by identifying them.
