Genetically modified foods have attracted much attention. Recently, the list of genetically modified foods and the so-called “method for identifying genetically modified crops†have been circulated on the Internet, once again pushing genetically modified foods to the top of the curve. In this regard, Zheng Fengtian, professor of the School of Agriculture and Rural Development at Renmin University of China, believes that the “genetically modified food list†circulating on the Internet is not reliable. Genetically modified foods should be categorized and treated with caution. Genetically modified staple foods should be treated with caution.
Do not imagine GM agricultural products as poisons
Zheng Fengtian believes that at present, there have been no cases where health problems have occurred in the short-term consumption of genetically modified foods. Do not imagine transgenic agricultural products as poisons. However, the long-term effects and consequences of regular consumption are still inconclusive. As a whole, global concerns are still relatively large. Therefore, genetically modified staple foods should be used with caution.
For genetically modified foods, Zheng Fengtian should be categorized and suggested that GM foods should be categorized. The safety of GM cotton, which humans do not eat, is not at all suspicious. GM soybeans and edible soybean oil actually do not contain genetically modified ingredients. There is no problem. As for genetically modified corn, its main function is to use as feed, and humans rarely or occasionally eat it, and its safety is not a big problem. The same is true of genetically modified papaya, which is not a staple food. Occasionally, the problem of consumption is not great.
Online circulated "genetically modified food list" does not fly
Zheng Fengtian said that genetically modified foods have always attracted much attention. The list of “genetically modified foods†circulating on the Internet, including “cherry fruit, big bell peppers, small pumpkins, and small cucumbers,†is in fact insignificant. The appearance of genetically modified foods is difficult to see, so some of the so-called “methods for identifying genetically modified crops†are also inaccurate. In fact, China does not allow the production or import of genetically modified crops. The People's Daily has published a list of genetically modified foods. Cotton, rice, corn and papaya have been approved for safety certification; only cotton and papaya are approved for commercial cultivation. The GM crops approved for import as processing raw materials include soybeans, corn, rape, cotton and sugar beets.
Neglecting or letting GM foods demonize it
How can the public really eliminate concerns about genetically modified foods and how can they meet the public's right to know about genetically modified foods?
Zheng Fengtian believes that neither genetically modified foods should be demonized, nor should it be assumed that genetically modified foods are generally safe and reliable, allowing the proliferation of GM foods. Genetically modified foods are good or bad and should be treated differently. For people who do not eat directly, they can be gradually promoted; for occasional use, some varieties can be tested and promoted; for the staple food that the residents eat every day, it should be prudent now.
Can not be genetically modified on staple foods
Zheng Fengtian said: “At present, genetically modified foods are considered to be safe, and those who have studied or engaged in biotechnology industry should account for the vast majority. However, there is still a lot of uncertainty in the whole world of genetically modified foods, so they can be studied and tested. , but I really can't try it on the staple food."
Recently, many scientists and college students voluntarily eat genetically modified rice to prove the safety of genetically modified foods. Zheng Fengtian believes that those practices are not prudent and misleading.
He said: "Each once or twice is no problem, but it does not mean that eating for 20 years is no problem. It is suggested that these "organizers" can engage in a "special zone" and allow them to insist on eating GM rice for 20 years. Only such long-term human body. The trial will ensure that there are no safety problems for 1.3 billion people's rations."
Proposal to focus on transgenic technology
"We can not conduct research on genetically modified staple foods, but it does not mean that we do not carry out research on genetically modified technologies. China should still focus on the research on this technology. It should work harder on species that are not directly consumed by humans, and it can also be used by some people who do not eat. Or occasionally eat a little variety to test, because humans have a certain amount of detoxification ability, if you occasionally eat a little, it is really unfavorable to humans, can not be basically discharged, just like taking medicine and occasionally taking some medicine. Security is in a controllable range, but if you take medicine every day, its side effects will exceed the human ability." Zheng Fengtian said.
