Disadvantages Of Genetically Modified Food

Improved Essays
In the modern society, there is an increase number of people concerned about food safety around the world. These food safety worries are primary about some new food species. This food which combines their DNA by using genetic technology is called genetically modified (GM) food. Scientists can make specific changes to food’s genetic structure and can alter food’s original characteristics. There are both advantages and disadvantages of GM food. The benefits of GM food are that researchers can improve the nutritional value of GM food and GM food can reduce pesticide use. However, there are also a number of renowned negative aspects such as GM food may take poisonous effects on human health and its unpredictable consequences of environment. Therefore, …show more content…
One of these is the unknown effect on human health. To begin with, (8) declares there is a growing concern that importing different country’s genes into food plant may have an unexpected and negative impact on human health. For example, a GM potato experiment which claims that rats digest ability are distinct after they fed GM potatoes and fed normal potatoes (8). Similarly, according to another experiment, some rats died within a few weeks after they ate GM tomatoes, because of the toxic effects (6). Otherwise, if GM foods such as GM peas probably have no adverse effects on animal testing, but this situation does not mean GM foods are safe for humans, because there have no enough strict specific dangerous assessments to guarantee the GM food safety for humans(6). In fact, scientists should test more initial safety experiments and followed by clinical experiments with volunteers to discover any possible harmful effects. Another most controversial issue is the unpredictable consequence of GM food on the environment. For example, scientists concern GM food may disrupt ecosystem processes, and people perhaps not see the negative effects on the environment because of the outcome which GM food affection for the environment may appear many years later (4). In addition, there are many strange and needless genes would be introduced in the traditional plants, …show more content…
One of the major health problems with GM food is the possibility of new allergies. Many children in the world are sensitive to allergies, which may cause by peanuts and other foods. (8) asserts there is a chance that scientists may introduce a gene into a plant and probably create a new allergen gene, thus cause an unexpected allergic reaction in those susceptible children. Further to this, To assessment of the allergen of GM food is difficult when the gene is transferred from a strange source or with unknown anaphylactogen, because while there are many appropriate animal supersensitive testing, no such experiments for allergy testing (6). Specifically, because of the deficiency of reliable ways for allergen experiment, it is impossible to make sure whether the GM plant is allergenic. Besides this issue, there is another significant drawback of GM food which is it may produce poison, then affect the environment. For example, GM food may produce higher levels of Bt toxin which is a type of poison than expected. While these crops are supposed to include only small of this toxin, there is also a probability that this toxin could be assimilated into the soil (4). Similarly, (8) also declares that B.t. toxins which produced by B.t. corn eliminate countless species of insects indistinctively and it is impossible to

    Genetic Roulette Genetically Modified Organisms, otherwise known as GMO’s, could potentially stop world hunger; however, the risks outweigh the greater good. The mixing of genetic material can raise the risks of allergic reactions to foods. Furthermore, tests have shown that many hazards and medical complications come from consuming genetically modified foods. In addition, genetically modified foods do not only affect foods like tomatoes but meats as well. Yes, Genetically Modified Organisms come in larger harvests, provide bigger than average results and are pesticide resistant; however, the risks that come with consumption of GMOs are too dangerous.…

    The main argument of the paper defended the safety of genetically modified organisms to the health of animals and people. Like many things, genetic modification may have the potential to cause harm, but evaluations and testing prevent any dangerous foods from going on the market. Genetic modification could also bring many benefits. These include the creation of healthier and cheaper crops. Overall, the use of GM foods has the same amount of risk involved as that of conventionally grown foods.…

    Introduction Genetically modified foods have become a major concern and have caused controversy regarding both their health and environmental effects (2). ' Using modern techniques of genetic engineering, it is possible to introduce specific genetic material derived from any species of plant, animal, or microorganism, or even a synthetic material, into different species of plant' (Journal 1) This allows a desired trait to be enhanced and reproduced. (3) (4) ' The resulting plants are commonly known as genetically modified (GM) plants; when used as food sources, they are known as GM foods.'…

    Every human loves to eat food, but does humans really know what is in these foods. Although certain foods are different, there has been controversies on Genetically Modified Foods around the globe. GM foods consist of growing foods with genetically engineered materials that don’t normally occur naturally. GM foods are created with various selected genes that come from one organism which is then transferred to another. Genetically Modified foods are quite controversial because GM foods enhance the taste, there is suspected health risks and potential negative effects on the environment when growing.…

    These 1783 studies were spread among a range of apprehensions from risks to humans and animals to hazards to the environment. The simple fact that 1783 studies with respect to the effects of GM organisms have been done proves that there is not an absence of research on this topic. The truth of the matter is that GM organisms are tested and regulated far more thoroughly than any other foodstuff intended for human consumption, and it's likely to stay that way. The only other principal argument of the anti-GMO movement appears to be that GM crops will ‘leak’ into the indigenous environment and somehow corrupt it – that they will become ‘pests’ in an ecosystem where they do not belong.…

    First, genetically modified organisms have been used in the food process for quite some time now. They have grown to be very popular, very quickly. In the article, “The State of Science”, the author Stuart Newman, comments that “Some critics suggested that the quality and safety of fruits and vegetables could be impaired, making them allergenic or toxic to humans” (Newman, 2013, p. 24). Worries of the food becoming toxic, or allergenic to humans arose, but regardless, the discovery of GMO’s came about, and the use of them grew. The scientists never expected it to become a normal occurrence in food production.…

    With the many possibilities that genetic modification has sparked, health and ethical problems have become a topic of disagreement for a significant portion of the population, especially the consumers. So far, genetic food modifications have been the answer to our drastic population growth, but many have accused it to cause cancer, assist to the destruction of the environment, and accumulate horrible future health risks for children. To test on some theories, certain tests have been done on animals and the results are somewhat shocking. According to Jeffrey Smith in his article “Health Risks- IRT”, rats fed GM foods showed liver problems, reproductive problems, and infant mortality. Other animals, such as sheep, cows, chicken and buffalo, who fed on GM corn, were linked to sterility, disease, and death.…
