Do you think genetically modified foods are harmful?

1.Genetic technology uses antimicrobial resistance genes to identify genetically modified crops, which may affect the efficacy of antibiotics on humans after the genetic food enters the human body, and mutated genes in crops may cause new diseases;

2.Protein transfer in transgenic technology may cause the human body to become allergic to foods that are not originally allergenic, and whether the new protein traits after segmentation and recombination fully meet the needs we envisage remains to be investigated.

3.The artificial refinement and addition of genes may increase and accumulate trace toxins and unforeseen biological mutations in food. It can even raise the level of the original toxin, or produce new toxins;

4.For the ecosystem, genetically modified food is to intervene in a specific species, artificially make it gain a competitive advantage in the living environment, which will inevitably destroy the timeliness of the natural survival law, cause changes in the ecological balance, and genetized organisms, bacteria, viruses, etc. enter the environment, preservation or restoration is impossible, which is more serious than chemical or nuclear pollution, and the harm is irreversible. <>

It is possible for new proteins to become allergens. However, given that current transgenic technology may not synthesize new proteins (such as killing insects by RNA interference), and many proteins are also found in other plants (such as putting the gene of corn in rice), the possibility of sudden encounters with new allergens is reduced.

Whether the traits of the new protein meet the needs really needs to be investigated. However, the scientific community should have a lot of confidence in this. Take me as an example, I have transferred fluorescent proteins into plants, and these fluorescent proteins can all exhibit fluorescence without exception, green light is green light, and blue light is blue light.

We are still sure of the whole transcription and translation system of plants. <>

I think it's harmful. According to the relevant information of relevant tissues, one of the transplanted genes is a carcinogen. There is nothing negotiable.

Whatever you want to do and how you wash it, anyway, I and my family, as well as my friends and their families, will never eat genetically modified things, we can't stop you, but please mark the genetically modified food.

At least now there is no evidence of the safety of genetically modified foods, and I think those who advocate the safety of genetically modified foods do not understand science and completely lack the scientific spirit.

Why do developing countries want to eat, relatives have people with high allergies, what medicine can't solve, I hope there is a standard, Professor Wang Qi of the University of Chinese Medicine said that there are 100 million people with allergies, too many food additives, too many allergens, and it can't be said that it will turn harmful, and I hope that the national department will deal with it properly.

No one can tell that GMOs are harmful and harmless, so they have to presume that they are harmful.

I don't know if it's harmful or not. I only know that when there are traditional foods to choose from, GMOs will not be chosen. Let's talk about it when it's all genetically modified food one day and you don't have to choose!

Since there is an argument, then stop for a while, take a look and then talk about it, don't rush to promote! Food has to be 100% safe, everyone says!

Compared to gutter oil, swill pigs, Sudan dyes, poisoned milk, and genetically modified are not a matter at all.

I follow the leader closely, if there is a genetically modified gene in the leader's special recipe, I will eat it, if not, don't lie to the people to eat it, I am also a life.

Even if it doesn't hurt, it's not like I haven't eaten it, so why try ......

Whoever thinks it is good will eat it without anyone stopping it, and don't force Chinese to eat it.

It's useless to write 100w propaganda articles a day. I didn't dare to force the logo, so I thought there was a problem.

There was no food to eat, and he ate a few meals when he was hungry.

Genetically modified foods or the presence of these hazards:

1. Change the environment: In the process of planting and growing, genetically modified foods are still very different from non-genetically modified crops, which will have a certain impact on the soil and the surrounding ecological environment, and this impact is not necessarily positive.

2. Pest upgrading: Genetically modified food itself still has the gene to kill insects, but pests can rely on elimination and evolution to produce higher resistance to this characteristic, resulting in the possibility that pesticides cannot be killed.

3. Reduce non-GMO crops: GMO crops are cheap, good seeds, and large yields, therefore, many farmers are willing to plant genetically modified crops, like the traditional non-GMO soybean production area in the Northeast, where local soybeans are reduced year by year, replaced by genetically modified soybeans, which is likely to cause the suspension and extinction of non-GMO crop seeds.

4. Psychological panic: Even if genetically modified food does not have any physiological harm, normal people still tend to choose non-genetically modified food when choosing food, so long-term consumption of genetically modified food and knowing it will cause a certain psychological burden and produce psychological diseases.

The reason why genetically modified foods are harmful is that artificially refined and added genes may be released at the same time as the intended effect.

It also increases and concentrates the original trace toxins in food. For example, the content of toxins such as toxins, soybean toxins, erucic acid, solanine, histamine and other natural toxins in genetically modified foods is likely to change.

Genetically modified foods may affect the growth of other organisms. For humans, genetically modified foods have passed all biochemical tests, but they cannot pass zoological feeding experiments.

With genetically modified foods everywhere, do we still have a choice? Is it okay to skip fruits, but can you skip rice?

Safety is the biggest obstacle to the production of genetically modified foods, the most debated topic among experts, and the most uneasy link for consumers. Are genetically modified foods really unsafe? Before and after the promulgation of the "Regulations", experts from Peking University and the Chinese Academy of Sciences basically agreed on the overall view of genetically modified food, that is, the safety of genetically modified food is not as terrible as some people think.

This issue can be debated, but we must not stop eating because of choking, and we must not stand still on the issue of developing the production of genetically modified food. Professor Xu Chongren of the School of Life Sciences of Peking University believes that there are three main types of concerns about the safety of genetically modified foods: first, whether the new ingredients in genetically modified foods pose a threat to consumers, and whether the new substances are dangerous; The second is whether genetically modified technology is harmful to organisms other than humans, such as insect-resistant cotton crops are not harmful to humans, but after the reduction of cotton bollworms, other organisms that feed on them will be affected, thus endangering biodiversity; Third, some genetically modified plants are very competitive, and crowding out other original species will also threaten biodiversity.

Of course, the impact on human health is currently the most worrying one. Compared with conventional food, the harmfulness of genetically modified food needs to be evaluated. Professor Xu Chongren believes that all genetically modified foods that have been approved for production have undergone safety evaluations and are safe to eat.

Of course, he also cautioned that after all, people have a relatively short history of eating genetically modified foods, so they may also be unsafe and need to be monitored for a long time. Researcher Zhu Zhen, deputy director of the Institute of Genetics of the Chinese Academy of Sciences, believes that safety and insecurity are only relative concepts, and no food can be said to be absolutely safe and absolutely unsafe, and genetically modified technology itself is safe. China's "Regulations" this time require genetically modified foods to be labeled when they are listed, in order to give consumers the right to choose.

The GM label is just to tell consumers the fact that it's pork and not beef, and that people who don't like pork can choose not to eat it, but it doesn't mean that pork is unsafe. Researcher Zhu Zhen is very optimistic about the development prospects of genetically modified foods, and he even said that maybe when there are genetically modified foods on the market one day, only a small amount of non-genetically modified foods need to be labeled. Experts believe that genetically modified foods should not be artificially compared to the safety of genetically modified foods"Ordinary"Food separated.

Rather, it should be seen how the nutritional content of the genetically modified food is different from that of conventional food, and if not, it is safe. Specifically, the principle of substantive equivalence evaluation includes nutritional evaluation of whether there is a change in the nutritional composition after the gene), toxicological evaluation (whether it causes malformation after consumption), allergy evaluation of whether there are allergens in the gene food, and whether it is safe for people in a region to eat for a long time; New plant proteins may appear after genetic alterations, which may lead to allergies); secondly, to see whether the genetically modified food has caused changes in the genetic material of the species; The third principle is to see if the new gene has any effect on its own metabolism after changing the original gene; The fourth is to see what effect it has on the microbiota of the human gastrointestinal tract after consumption.

Remember.

1. The safety of all genetically modified crops should include food safety, planting safety, ecological security, economic security and many other aspects.

Edible: If it is cooked food, the activity of the gene will definitely be incapacitated during cooking and heating, and there is no danger. If it is raw food, in the past, all biological food hazards were mainly caused by chemical processes, such as the accumulation and transformation of chemical substances.

GMO occurs through the consumption of food or something, hehe, it should be too much to think about. Therefore, of course, the food safety of genetically modified crops should be experimented, but the main focus is on whether there are substances that may be harmful through the chemical reaction of the cooking and digestion process.

Planting safety refers to whether dangerous products (pollen, toxic substances, etc.) occur in the process of planting in a large area, and whether the planting behavior may aggravate ecological damage (for example, the Ming Dynasty in the Yangtze River basin began to open up land on the slopes of the mountains to introduce corn, causing soil erosion, and the Yangtze River began to turn into the Yellow River). And so on. There are also many issues related to the ecological aspect.

Ecological security is very important, because crops may undergo new genetic changes due to their own reproductive variation, or they may also lead to genetic changes of other species through pollen transmission, and these new genetic species may become invasive special species in the ecology and cause ecological disasters. In addition, it may also cause changes in the behavior and quantity of stealing organisms (rats, birds, etc.) through certain hormone-like substances, or cause changes in water and soil through excessive absorption of water nutrients and special minerals. These can lead to serious ecological crises that are difficult to foresee.

Economic security lies in the impact that genetically modified crops may have on the agricultural economy, the agro-processing industry, and the manufacturing industry that depends on crops. For example, after the large-scale dependence on genetically modified crops, the global or regional industrial transfer, the first system change, and the supporting industry change will occur; Large-scale production gaps due to the loss of traditional seed production capacity in the breeding industry after the discovery of crop problems; The cost of planting has gradually increased after the transgenic technology was controlled by international giants.

All of the above, hanging one leak.

Therefore, the safety of genetically modified crops is a strategic topic that should be studied from a multidisciplinary perspective. The research of agronomists is only a small part of it.

Of course, at present, if it is a genetically modified crop product that has been approved by the state, it can basically be assured of the safety of cooking and eating. At least you won't have a genetic change as a result of eating a cooked meal.

If you are concerned about whether the state has carefully assessed the overall safety of the crop, you can of course express your concern and resist it with purchases.

Genetically modified food (GMF) refers to food, food raw materials and food additives manufactured and produced by genetically modified organisms; Genetically modified organisms (GMOS) refer to organisms whose genetic material has been genetically altered, and their genes are genetically modified by genetically modified technology, rather than by natural proliferation or natural recombination.

At present, there is still a great controversy in the academic community about the safety of genetically modified foods, and there is no definite conclusion. As far as countries are concerned, all countries have a more cautious attitude towards genetically modified foods, but the degree is not quite the same; Some countries are more open to caution, such as the United States, which already produces considerable amounts of genetically modified soybeans (the exact amount can be searched on the Internet). As far as China is concerned, it is still relatively conservative, and all commercially available foods must be clearly labeled for any genetically modified ingredients (including raw materials and additives, etc.).

For genetically modified organisms used in food, researchers will try their best to avoid transferring potentially harmful genes in the research and development stage, but it may take one or two generations or even several generations for the food they make to be apparent.

Therefore, for genetically modified food, everyone has their own attitude, or divide people, after all, genetically modified food also has its great advantages.

It is better not to eat it, because the technology is not very mature.

Genetically modified foods have many advantages: they can increase the yield per unit area of crops; It can reduce production costs; Through transgenic technology, the ability of crops to resist pests and viruses can be enhanced; Improve the storability of agricultural products, extend the shelf life, and meet the needs of the people's livelihood Genetically modified food - potatoes.

the need for an ever-increasing level of living; It can greatly shorten the time for crop development; It can get rid of the influence of seasons and climate, and the four seasons are low-cost**; Break down species boundaries and continue to breed new species to produce food that is good for human health. Genetically modified foods also have disadvantages: the so-called increase in production is not affected by the environment, and in the event of natural disasters such as rain and snow, the yield may be reduced even more.

And a number of studies have shown that genetically modified foods have damage to the immune function of mammals. Studies have also shown that after the experimental hamsters ate genetically modified food, they became extinct in their third generation.

Some researchers believe that the artificial refinement and addition of genes may achieve some of the effects that people want to achieve, while also increasing and accumulating trace toxins in food.

People with one food allergy sometimes develop allergies to foods they didn't have a previous allergy to, more than genetically modified foods—there are hidden dangers.

For example, if scientists add a certain gene of corn to the genes of walnuts, wheat and shellfish, and the protein is also added with the genes, then people who have been allergic to corn may be allergic to these walnuts, wheat and shellfish.

When scientists add a foreign gene to a plant or bacteria, that gene is linked to other genes. When people take this modified food, the food will pass on the antimicrobial resistance gene to the disease-causing bacteria in the human body, making the human body resistant to the antibiotic.
