Arowana edible blended oil bottle is marked with invisible small print: soybean oil is extracted from genetically modified soybeans, and rapeseed oil is extracted from genetically modified rapeseed. The brand marketing of Arowana is quite good. It is conceivable that how many people in China have eaten the oil extracted from genetically modified soybeans.
Genetically modified foods are everywhere: potatoes, tomatoes, papaya, soybean oil, salad oil, blended oil, drinks, milk powder and biscuits. ......
During the period of 1998, the American media reported an exclusive interview with Professor Pusta of Reuters Institute. He warned people to pay attention to genetically modified foods that have been popularized before their safety has been fully proved. After the experiment, the organ growth of mice was abnormal, the body weight and organ weight decreased, and the immune system was destroyed.
The safety of genetically modified food has always been controversial, and there is no unified understanding in the world at present. Its existence is only 10 years, and many long-term effects are still unknown. Eating genetically modified food is like treating yourself as a mouse, and the risk is unpredictable. Therefore, the precautionary principle should be adopted for genetically modified foods, and genetically modified raw materials should not be used in food production before the long-term safety has been fully determined.
At present, Mexico prohibits the cultivation of genetically modified corn; EU suspends import of genetically modified food; Japan, Australia, New Zealand and other countries require genetically modified foods to have clear labels indicating the content of genetically modified ingredients; Many supermarkets in Britain prohibit the use of genetically modified organisms as raw materials to produce food.
A person familiar with the matter in China pointed out with anxiety, "The research on genetically modified food shows that herbicide-resistant genetically modified soybeans also reduce the anti-cancer components, and insect-resistant genetically modified corn not only increases the mortality rate of pests, but also affects the maturity of beneficial insects. Eating genetically modified potatoes will damage the internal organs and immune system of small animals. People ... ". Europeans prohibit the sale of genetically modified foods in Europe precisely because they may be harmful to human health; Even in the United States, dealers are required to label genetically modified foods.
1In August, 998, British professor Pu Zitai found that the immune system of mice was destroyed after eating genetically modified potatoes; It has also been reported in the United States that some natural enemies of pests were killed by transgenic plants; On May 22, 2005, the British Independent also disclosed a report by Monsanto, a well-known biotechnology company, saying that rats fed with genetically modified food had organ variation and blood composition changes. These news not only shocked the whole world, but also made more people doubt the safety of food made of genetically modified raw materials.
(1), the safety test has not been conducted for a long time: genetically modified food has changed the natural properties of the food we eat, and the biological substances it uses are not the part provided by human food safety. No one knows whether this food is safe without long-term safety test.
(2) Toxin production: Genetically modified food will produce unpredictable biological mutation, which will produce higher levels and new toxins in food. Losey, J.E. et al. (1999) reported that after spraying transgenic Bt corn pollen on the leaves of a plant milkweed, Papilio Papilio had few edible leaves and slow growth, and the mortality rate of larvae was 44% in 4 days. However, none of the control group (leaves fed with Bt corn pollen) died. Insecticidal toxins produced by genetically modified crops can penetrate from the roots to the surrounding areas, but it is not clear what effect they will have.
(3) Allergy or allergic reaction: Genetic technology will produce unpredictable and unknown allergens in food. It is reported that subjects who are allergic to Brazil nuts are also allergic to soybeans genetically modified with this nut. Scientists transplanted the characteristics of Brazilian walnuts to soybeans, but as a result, some people who are allergic to walnuts may be allergic when eating soybeans. Phytocoagulants are toxic to some pests, and genetically modified foods must not contain such toxic substances.
(4) Reducing the nutritional value of food or degrading important ingredients in food: The purpose of genetics is to remove or inactivate substances that people think are unnecessary. These substances may be unknown, but they are basic. For example, it has a natural ability to inhibit cancer (Pariza, M.W., 1990). American research data show that in soybeans with herbicide-resistant genes, anti-cancer components such as isoflavones are reduced. The false freshness of genetically modified foods confuses consumers. Red tomatoes with fragrance and luster can be preserved for several weeks, but their nutritional value is low. When consumers buy fruits or vegetables, they can't accurately judge the true quality of the products only by appearance and texture. Transgenic microorganisms disturb the natural circulation of nutrients in the environment.
(5) Antibiotic-resistant bacteria: Gene technology uses antibiotic-resistant genes (such as kanamycin, ampicillin, neomycin, streptomycin, etc.). ) to identify transgenic crops, that is, crops have antibiotic resistance genes. These genes affect us through bacteria. British research shows that mutant genes in genetically modified crops may enter organisms. If the mutant gene crosses the population and is transferred to bacteria, the result may lead to new diseases. Although this probability is very small, if there is an incurable and widely spread disease that poses a serious threat to life, the consequences will be unimaginable.
(6) The problem cannot be traced back: if it is not marked, our public health authorities will not be able to find the source of the problem, and the potential harm is doubtful.
(7) Side effects can be fatal: Mayeno, A.N. et al. (1994) reported a new disease of unknown cause, mainly manifested as eosinophilic myalgia. Clinical manifestations include paralysis, neurological problems, pain and swelling, itchy skin, heart problems, memory loss, headache, light sensitivity and emaciation (Brenneman, D.E. et al.,1993; Love, L.A., etc., 1993). It was later discovered that tryptophan was produced by genetically engineered bacteria born in a Japanese company. Three months later, the eater fell ill, resulting in 37 deaths, 1, 500 people were partially paralyzed, and more than 5,000 people were occasionally weak. According to the determination, the content of 0. 1% can kill people.
According to the provisions of the Measures for the Administration of Labeling of Agricultural Genetically Modified Organisms implemented by the Ministry of Agriculture on March 20, 2002, the first batch of agricultural genetically modified organisms subject to label management are:
(1) Soybean seeds, soybeans, soybean flour, soybean oil and soybean meal.
(2) Corn seeds, corn, corn oil and corn flour.
(3) Rapeseed, rapeseed, rapeseed oil and rapeseed meal.
(4) Cotton seeds
(5) Tomato seeds, fresh tomatoes and ketchup.
It has been found that genetically modified soybeans can cause serious allergic reactions; Tryptophan, a food additive produced by genetically engineered bacteria, has killed 37 people and disabled more than 1500 people. Recently, it was found that the milk of many supermarkets in the United States contains genetically modified bovine growth hormone, which has been used in pasture. Tomatoes produced by a famous genetic engineering company are storable and easy to transport, but they contain antibiotic-resistant genes, which can remain in the human body. Man-made characteristics and inevitable imperfections will be passed down from generation to generation, affecting other related and unrelated creatures. They will never be restored or controlled, and the consequences are incalculable at present.
Ye Yongmao, an expert on food safety in China, also put forward his own opinion: "Genetically modified foods have at least five potential dangers in theory: producing toxins, causing human carcinogenesis and teratogenesis or gene mutation, causing allergic reactions, causing imbalance in the nutritional structure of food, making people resistant to drugs, and making the natural and ecological environment unbalanced. Now many European countries resist the listing of genetically modified foods. "
