Reporter Chen Yanpeng reports from Beijing
A research report recently released by the Heilongjiang Soybean Association stated that high incidence of domestic tumors is highly correlated with the consumption of genetically modified soybean oil (7332, -64.00, -0.87%). The report came out and caused a lot of frustration in all walks of life. Some experts in the field of food safety have refuted allegations that the deduction does not have any basis.
On June 25th, the Heilongjiang Soybean Association responded to a reporter from the China Times that the experiments of French and Russian scientists have proved that the genetically modified soybean oil can cause cancer. In addition, in the past ten years, the greatest change in food consumption among residents is the replacement of genetically modified soybean oil. Any analysis of the causes of cancer will consider the possible impact of genetically modified soybean oil.
“We hope relevant experts can push the boat, comply with the interest demands of the country and the people, show the people the demonstration report and the process of genetic safety, and further advance scientific experiments on genetic safety,†the association said.
The origin of the report
"The genetically modified soybean oil may cause cancer" once said, once again push the GM food to the cusp.
Wang Xiaoxiao, deputy secretary-general of the Heilongjiang Soybean Association, told the reporter that the basis for this inference came from the comparison of the characteristics of domestic tumor onset regions and China's genetically modified soybean oil consumption regional characteristics of the two charts, it will be found that the relevant areas have a striking coincidence.
According to the “2012 China Cancer Registry Annual Report†issued by the China National Cancer Registry, the characteristics of the onset of cancer in China are obvious. Among them, high-incidence areas of esophageal cancer are concentrated in the central plains of Henan and Hebei, and gastric cancer is concentrated in the northwest and coastal areas of Shanghai, Jiangsu, Gansu, and Qinghai. In the provinces, liver cancer is concentrated in the southeast coast and northeastern Jilin.
"In a coincidence, Henan, Hebei, Gansu, Qinghai, Shanghai, Jiangsu, Guangdong, and Fujian are all areas of concentrated consumption of genetically modified soybean oil in China, and these areas are also the focus of onset of domestic cancer." Wang Xiaoyu said .
Shandong and Jiangsu are two neighboring provinces. As the two provinces with the largest number of imported genetically modified soybeans in China, Jiangsu Province has high incidence of gastric cancer, while Shandong Province does not. Wang Xiaoyu believes that this is related to the characteristics of oil consumption. Specifically, Shandong residents mainly use edible peanut oil, Heilongjiang mainly uses soybean oil, and the province is also a domestic soybean protein processing concentration area. The processing soybean protein requirement must be Heilongjiang natural soybean, and therefore its by-product natural soybean oil also becomes a local resident. The first choice.
There is more than this evidence. Wang Xiaoyu found that Hunan, Hubei, Zhejiang, Guizhou and other provinces are not related to the onset of tumors, because these provinces are mainly edible rapeseed (5210, 5.00, 0.10%) oil, tea oil, etc. The proportion of soybean oil consumption is low.
In addition, Jilin Province’s attention has also been drawn to Jilin Province where liver cancer is concentrated: In Inner Mongolia, Heilongjiang, Jilin, and Liaoning, a region of three provinces in the northeast, the local customs and habits are similar. Although the social and economic development of industry and agriculture is different, Jilin Province is the only one with concentrated onset of tumors. Area.
"The biggest difference between the three provinces and one region is that Jilin is a major province of China's corn (2415, -4.00, -0.17%) for planting, processing, and consumption. Deteriorating corn can induce aflatoxin, and aflatoxin can directly lead to liver cancer. Whether there are genetically modified corn factors leading to corn deterioration, hope experts argue.†Wang Xiaoyu concluded.
Experts questioned
The GM soybean oil caused a cancer and caused some experts in the field of food safety to question it.
Chen Junshi, academician of the Chinese Academy of Engineering, said at a media open day held by the National Food Safety Risk Assessment Center that the import of genetically modified soybeans in China is a fact and the high incidence of cancer in our country is also a fact. However, it is unfounded to combine these two issues. So far, there is no evidence that GM foods pose a health hazard to consumers.
However, Wang Xiaoyu believes that although there is no scientific experiment to prove that the genetically modified soya bean oil has caused cancer, the inferences made are based on the fact that it is not fabricated out of thin air. He analyzed the extreme geographical environment factors, the geographical distribution of chemical elements, pathogenic biological communities, and mental factors, and concluded that the environmental climate factors have little relevance to tumor incidence.
"So there are only dietary factors." Wang Xiaoyu believes that "diseases from the mouth" means that diseases are mostly caused by foods with problems such as grains, fruits and vegetables, meat and eggs, aquatic products, drinks, snack foods, spices, and dairy products. It causes disease, so the relationship between diet and onset of cancer cannot be ruled out.
Another view of Wang Xiaoyu is that genetically modified soybean oil can threaten the health of consumers.
“The soybean modified by genetically modified technology has unpredictable effects on the essential fatty acids and fat-soluble vitamins of soy oil. Changes in the critical value of the role of soybean oil may render the human organs ineffective in exerting anti-cancer and anti-tumor functions. The consumers of genetically modified soybean oil are more likely to suffer from cancer and infertility, said Wang Xiaoyu.
However, Peng Yufa, deputy chairman of the Agriculture Genetically Modified Organism Safety Committee and a researcher at the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences, did not agree with Wang Xiaoyu's conclusion. He believes that genetically modified products represent protein, and the state stipulates that the imported GM soybeans can only be used to crush oil and feed. Proteins have been removed during the refining of soybeans into oil. Therefore, genetically modified components remain in soybean oil. There is no basic existence.
The Heilongjiang Soybean Association responded to this by saying that the genetically modified soybean oil does not contain any genetic components without protein, which is suspected of masking the functional role of soybean oil. The simple scientific common sense is: After soybeans are genetically modified, their traits will change. Both appearance and nutrient components and functions will be affected. This is scientific knowledge. After soybeans have been genetically modified, there is no change in oil yield and nutrient function. I hope relevant experts can explain it.
Self-interest demands?
In fact, the debate over the safety of genetic modification has never been interrupted.
According to Wang Xiaoyu, genetically modified foods cause cancer, and international studies have long had long-term experimental conclusions. In September 2012, scientists from the University of Kane, France, Seralini and other scientists published in the "Journal of Food Chemistry and Toxicology," the results of the study said that after a two-year test of 200 experimental mice, which used genetically modified corn NK603 and was "Roundup" (Rongda) Contaminated feed-fed mice are susceptible to tumor and visceral damage.
According to a report by China Food Science and Technology Network, in 2010, scientists from Russia's National Association for Genetic Safety and the Institute of Ecological and Environmental Problems Alexei Surov and other scientists jointly conducted experiments and found that animals that consume genetically modified foods will lose reproductive ability.
In this regard, Zhu Yi, an associate professor at the China Agricultural University's School of Food Science and Nutritional Engineering, said that these studies have long been questioned by mainstream foreign scientists and they believe that they are not rigorous and not convincing. He said that the World Health Organization, the European Commission, the US FDA, and the Ministry of Health and Welfare of Japan clearly stated that GM foods are safe, and because they use more precise technologies, they are subject to more comprehensive and rigorous testing and risk assessment.
The Heilongjiang Soybean Association responded that, first of all, the conclusion of international cancer experiments should not be groundlessly denied; second, the incidence of cancer in China is increasing, and the most suspect is food. In the past ten years, the greatest change in food consumption among residents has been the substitution of genetically modified soybean oil. Any analysis of the causes of cancer will consider the possible effects of genetically modified soybean oil. Therefore, the association's inference about the carcinogenicity of genetically modified soybean oil is not at all satisfactory.
Some people also believe that the Heilongjiang Soybean Association represents the interests of the non-GM soybean industry, and the release of genetically modified soya bean oil is to resist the impact of imported soybeans and to support and rescue the domestic non-genetically modified soybean industry on the brink of collapse.
China used to be a major exporter of soybeans. However, over the past decade, there has been a surge in soybean imports and a decrease in the area of ​​domestic soybeans. In China, more than half of the edible oil is soybean oil. Soybean oil accounts for more than 90% of the domestic market but it is genetically modified soybean oil. In the major soybean producing areas, a large number of processing companies have been shut down or have gone bankrupt, which has exacerbated the internal difficulties of the domestic soybean industry.
“We do not have such interest claims, that is, we want to initiate a study, and we hope that the authoritative department will have a further study report. We can have a long-term experiment to prove the safety of genetically modified soybean oil through an open and complete experimental process.†said Wang Xiaoyu. .
