How much do you know about GM foods?

The melon sac is a bright yellow striped watermelon. It tastes like an apple pear like a pear, a brightly colored bell pepper, a purple sweet potato and a potato. It is called a “small tomato” cherry fruit. It has different colors of corn kernels. In recent days, the People’s Daily has ridiculed a “list of genetically modified foods” on the Internet, and the controversial genetically modified foods have once again become the focus of discussion. Some people call to ask if the bizarre fruits and vegetables are genetically modified foods? Is genetically modified food harmful to humans? In response, the reporter conducted an investigation.

Hybridization and genetic modification are two different things

Earlier, the so-called “genetically modified food list” that was circulated on the Internet misled many consumers. On this so-called “list”, the cherry tomatoes, bell peppers, pumpkins, and cucumbers were all on the list.

"Actually, these quasi-genetically modified fruits and vegetables that these people in the market think are more novel are not genetically modified foods," said Zhou Qi, chief of the Rural and Social Development Section of the Municipal Bureau of Science and Technology. The suspected genetically modified fruits and vegetables are basically based on techniques such as hybridization. Varieties of modified fruits and vegetables are totally different from genetically modified foods.

According to Zhou Qi, genetically modified foods refer to the use of genetic engineering (transgenic) technologies to embed (non-homogeneous) exogenous genes in the genome of a species. Embedded genes are basically genes that are resistant to disease and insects. hurt.

According to information from the Ministry of Agriculture, as of now, only two types of cottonseeds and papayas have been commercially grown in China. In addition, China has also imported five genetically modified crops of soybeans, corn, canola, cotton and sugar beets as raw materials for processing.

GM food dispute "riding"

In addition to misunderstandings about the “what is genetically modified food” problem, the reporter found during the survey that citizens also questioned the safety of genetically modified foods.

Citizen Liao Xinyi said: "I am definitely more willing to purchase non-genetically modified foods. Genetically modified foods have changed the genetic make-up of foods, and it is not good."

Citizen Chung-chun Chung also said: "Non-genetically modified foods are authentic, and genetically modified foods are artificially improved and unnatural."

One citizen who did not wish to be identified even said in an interview with reporters that long-term consumption of genetically modified foods would be harmful to the human body and would change human genes.

“The reason for this misunderstanding is that we don’t understand biological knowledge. Once all genes enter the human digestive system, they will be broken down into 4 common nucleotides in the biological world, so that they can be absorbed and utilized by our cells. What is the human gene?” said Ling Liping, chief of the Science and Technology Education Section of the Municipal Bureau of Agriculture and Food.

Ling Liping believes that genetically modified foods have been “demonized” in the rumors of rumors. “Online is also rumored that Americans do not eat genetically modified foods. In fact, as the largest producer and consumer of genetically modified crops in the United States, 86% of corn, 93% of soybeans, and 95% of sugar beets grown are GM crops. Most of the GM crops are for American residents to eat,” Ling Liping said. “Transgenic technology is the result of scientific and technological progress. China has a particularly strict procedure for the approval of genetically modified crops. From Ganzhou’s local, we organize at least twice a year. Law enforcement actions on relevant scientific research sites prevent the abuse of genetically modified technology and the production of illegal genetically modified foods at the source.”

However, some experts have reservations about the safety of genetically modified foods. “The impact of genetically modified foods on the human body is a long-term process. Although so far there has not been a case of food safety problems caused by the consumption of genetically modified foods, I cannot guarantee that the long-term consumption of genetically modified foods will have no effect on the human body.” Zhang Honglin, deputy director and researcher of the Bureau of Science and Technology, said.

Quzhou is not a GM crop production area

The reporter visited the major supermarkets in the city and learned that genetically modified foods mainly exist in the fields of soybean blend oil, soy sauce and imported fruits.

Liu Xiangyan, a buyer of a large supermarket, told reporters: “The use of genetically modified edible oils is cheaper than the use of non-genetically modified edible oils. In general, cheaper goods sell better, but some consumers have indicated that they should use them. Non-genetically modified edible oils are produced, so non-genetically modified edible oils are also very useful."

The reporter saw in a certain supermarket in the city that some of the soybean blend oil clearly indicated on its packaging that the raw materials used were genetically modified soybeans. For example, the raw material originated from "Brazilian" "Fragrant Garden" first-grade soybean oil, and its raw material composition column indicates the use of genetically modified soybeans and genetically modified soybeans.

In soy sauce products that use genetically modified raw materials, products that use non-genetically modified raw materials are indicated. For example, the soy sauces of brands such as “Lee Kum Kee”, “Flavorful Fresh” and “Haitian” are clearly marked with the use of non-genetically modified raw materials.

In the fruit zone of the supermarket, the reporter saw that as long as the country of origin is foreign, they all indicate the four-digit code label that represents the beginning of the "4" for genetically modified foods, but the country of origin is not marked at all. Contrary to soy blend oil and soy sauce products, imported genetically modified fruits are often expensive.

“Cangzhou is not a production area for genetically modified crops,” Zhang Honglin told reporters. “Cotton and papaya, two kinds of genetically modified crops that have been commercially grown in the country, are not the main economic crops in Zhangzhou. As far as I know, Chenzhou has not grown genetically modified crops. "(Reporter Xie Ruo leisure trainee reporter Zhang Wenying)
