With the development of science and technology, biotechnology has been applied as one of the eco-techno-political technologies in recent years. Therefore, genetically modified foods benefit a lot the human race, especially in developing countries which have a large number of people. With the wilder use of genetically modified foods, they not only solve the subsistence problems but also produce economic benefits. Additionally, genetic modification may help the plants perform a job that they cannot do, which satisfies the public requirement for a higher life quality. However, after ten-year introduction in EU, genetically modified foods are still unpopular. Despite the concerns about biological safety, particular genetically modified foods might impact the environment indirectly. Moreover, it is indeed hard to find an effective way to solve the drawback of genetically modified foods. Hence, whether they are positive or not are still debates

First of all, it is necessary to display a clear definition and societal issues towards genetically modified foods. Genetically modified foods are species whose genes have been changed to perform a desired function (Le, Fernandez & Gabriel, 2004). However, the public concerns about genetically modified foods are not optimistic. In Western Europe, 70 per cent of consumers are against genetically modified foods (Ritsema, 2006). The huge number of rejection lead to the decline of market and industry. Thus, why do many people against genetically modified foods.

While genetically modified foods bring benefits, there are still several safety issues towards genetically modified foods. As for human health, the concerns for safety, allergenicity, toxicity, carcinogenicity, and altered nutritional quality of food are controversial. Due to the fact that GM contains the transfer of genes that may code for proteins not normally present, which means there exist unknown character will be more or less allergenic than their conventional

    GM FOOD As the population in the world seems to be a huge serious problems, the demand on foods will be taken a very important role on solving this problems. Fortunately, biotechnological scientists had developed a technique which can modify organisms genetically (GMO). Genetically Modified Organisms are the process normally transferring genes, which were so-called DNA, between two species. Those organisms will be modified their genetic structure by using biotechnology. This technique can be used…

    GM (Gentically Modified) or GE (Genetically Engineered) foods are plant crops created for the consumption of humans and animals using the latest genetic engineering techniques. Genetically modifying food involves altering a plant 's genes, either by removing a gene or adding a gene from another living being. There has been high controversy around introducing GM foods as a solution to the world food crisis. Are GM foods harmful of helpful? Many concerns have risen around GM foods, including economical…

    What is GM food? Genetically modified food (GM food, or biotech food) refers to any food or food ingredient that is, or is derived from, an organism in which the genetic material has been modified using modern biotechnology. How does GM food be produced? Nowadays, scientists can identify and modify genes controlling specific characteristics using modern biotechnology. They use a variety of biotechnology, such as biochemical "scissors" to cut the DNA sequence at a specific place, and then select…

    INTRODUCTION Genetically modified foods (GM foods or biotech foods) are foods made from genetically modified organisms (GMOs), specifically, genetically modified crops. GMOs have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective…
