Extending from "Golden Rice" you must know the truth of genetic modification
The International Environmental Protection Organization Greenpeace reported to the media on August 30th, 2012 that a scientific research institution in the United States has released its results of 24 GM rice experiments conducted on children in Hunan Province, China. In response, Greenpeace expressed its strong condemnation.
According to the introduction of Greenpeace, the study aimed to test the role of transgenic "golden rice" developed by Syngenta Inc. in supplementing human vitamin A. In this study, 72 healthy children aged 6 to 8 years were selected. The children were all students from a primary school in Hengyang City, Hunan Province. Researchers ordered 24 children to eat 60 grams of golden rice every day for 21 days and test their vitamin A levels. They concluded that golden rice is equivalent to vitamin A capsules.
Greenpeace stated that as early as 2008, the Ministry of Agriculture and the Zhejiang Provincial Department of Agriculture stopped the project immediately after learning of the research plan. However, a paper published in the American Journal of Clinical Nutrition on August 1, 2012 showed that this research, led by Tang Guangwen of the Tufts University and funded by the U.S. Department of Health and the U.S. Department of Agriculture, was finally completed.
"Genetically modified foods have a potential risk to human health. An American agency tests genetically modified rice with Chinese children's bodies. We are indignant and inconceivable that such experiments can be carried out. The Ministry of Agriculture and the Zhejiang Provincial Bureau of Agriculture were already four years ago. "The reason why we stopped this experiment and why it can be revived is unknown." said Fang Lifeng, director of the Food and Agriculture Program at Greenpeace.
Fang Lifeng pointed out that China does not need genetically modified rice and it is entirely possible to use mature existing methods to solve the problem of vitamin A deficiency. In addition, he also pointed out that since the children in the study had no vitamin A deficiency before the start of the study, the strength of this experiment for the treatment of vitamin A deficiency remains to be seen.
Does Human and Animal Experiments Safely Test?
Golden rice has become a hot spot, naturally because of its "transgenic" status. Under the demonization of green and equal extreme environmental protection organizations for many years, most people are full of “false facts†about genetic modification and are therefore full of fears about genetic modification. The most popular sentence is "safety has not been confirmed" and the other sentence is "If the harm is manifested after several generations."
We need to know that "absolute security" cannot be "confirmed" for any kind of food. Those traditional foods that we had eaten for thousands of years and believed to be “safe†only found no major, acute hazards. Chronic, minor poisons, even if they are not known, can only be found under the modern scientific detection and statistical process. A typical example is borax, which has historically been used in foods all over the world for a long time. However, after the detection of modern methods, it was found that it was easy to use "overdose" to the point of harming health. Eating rice is just part of people's lifestyle. There are many factors that affect health. Human experiments cannot allow people to live in the same way for a long period of time, so there must be various "mixed factors." In other words, even if the subject has some kind of symptoms, it is quite difficult to "confirm" what kind of factors lead to it.
A hundred years ago, scientists realized that the safety of food or food ingredients tested by “eaten people†was neither humane nor reliable, and gradually established procedures for testing poisons through animals. Although animals differ from humans in species, animal experiments can allow animals to live under the same conditions for a long period of time. They can also give them doses much higher than normal, so that minor hazards are “amplified†and easily detected.
However, such "nutrition-enhanced" foods such as golden rice, such animal experiments are difficult to carry out. First, it is a staple food that cannot be "magnified" by increasing the dose. Second, it strengthens nutrition. To make up for the enhanced nutrient content in the food as a control, it is necessary to introduce this nutrient in other ways, which in turn increases the experimental variables.
Therefore, for nutrition-enhanced GM foods, using animal experiments to test safety is not a good solution. Neither the United Nations Food and Agriculture Organization and the United States Food and Drug Administration require animal experiments on such foods to detect safety. Of course, "does not require" does not mean that it will not be done. Such tests can still provide valuable information, so we can also see that some genetically modified products use animals or humans for safety experiments.
