1, nutritional damage
The changes of main nutrients, micronutrients and anti-nutritional factors in genetically modified food will reduce the nutritional value of food and make its nutritional structure unbalanced. Scientists believe that foreign genes will destroy the nutrients in food in a way that people don't know yet.
2, or unsafe
No long-term safety test: Genetically modified food has changed the natural properties of the food we eat. The biological substances it uses are not the part provided by human food safety. No one knows that this kind of food is safe without long-term safety test.
3. Eosinophilic myalgia
Mayeno,A.N et al. (1994) reported that a new and unexplained disease occurred, mainly manifested as eosinophilic myalgia. Clinical manifestations include paralysis, neurological problems, painful swelling, itchy skin, heart problems, lack of memory, headache, photosensitivity and emaciation (Brenneman,D.E et al.,1993; Love,L.A et al., 1993). It was later found that it was caused by tryptophan produced by genetically engineered bacteria born in a Japanese company. Three months later, the eater became ill, resulting in 37 deaths, 1500 people were partially paralyzed, and more than 5,000 people suffered from occasional weakness. According to the determination, the content of 0. 1% can kill human body.
4. Gastrointestinal problems
The most worrying thing is that the genes inserted into genetically modified soybeans are transferred into the DNA of bacteria living in our intestines and continue to play a role. This means that eating corn flakes caused by Bt corn will turn our intestinal bacteria into living pesticide factories, possibly until we die. Americans have had a dramatic increase in gastrointestinal problems in the past decade. This large increase is mostly attributed to the consumption of genetically modified foods by doctors. The most serious problem does not stop there.
5. Allergy
In the transgenic operation, foods containing genes extracted from bacteria may lead to the expansion of allergic phenomena and make people have allergic reactions, especially for children, pregnant women and adults with allergic constitution. For example, scientists added a certain gene of corn to the genes of soybeans, wheat and shellfish, and protein also added it with the gene, so people who used to be allergic to corn may be allergic to these soybeans, wheat and shellfish.
6. Cardiovascular and cerebrovascular diseases
These genetically modified soybeans were implanted with saturated fat genes by their biologists. These genes lead to soybean oil produced by transgenic soybeans, which will form a lot of saturated fat after entering the human body, increase the blood viscosity of blood, and lay a chronic time bomb for major cardiovascular and cerebrovascular diseases such as fatty liver, hyperlipidemia and cerebral thrombosis.
7. Initiate new diseases
Transgenic technology uses antibiotic-resistant genes to identify transgenic crops, which means that crops have antibiotic-resistant genes. These genes affect us through bacteria. British research shows that mutant genes in genetically modified crops may enter organisms, and the result may lead to new diseases. If similar results occur in humans and animals, it is possible to cultivate the most powerful superbacteria that antibiotics can't kill.
