Insight into the Genetically Modified Foods: Concerns of Safety to Food Development (Part II)
Science Insights, 2016
There are a lot of non--food uses of GM plants like timber, use to manufacture paper, in the chemical industry and as biofuels. Pharmaceuticals made from pro--teins can be made from GM plants. Plant tissues in the processed shape can be used potentially as edible vaccines. According to an estimate, 250 acres of green--house space can be enough to let the GM potatoes grow and meet the annual demand of hepatitis B vaccine in the whole South East Asia. Any harmful effect on the environment through large--scale growth of GM plants can indirectly show impacts upon human health. GM plants are also evaluated on the basis of how they might have a constructive role to perform in the environment by partial re--moval of contaminants-a practice often termed as phytoremediation. A lot of NGOs and media organizations are ruthlessly opposed to production of GM plants. Scientists need to engage the common man to ensure that the issue de--mands more rational approach of thinking. The opposition is making serious im--pacts as many underdeveloped countries that can get a lot of advantage from this technology.■
Benefits and risks associated with genetically modified food products
Scientists employing methods of genetic engineering have developed a new group of living organisms, termed 'modified organisms', which found application in, among others, medicine, the pharmaceutical industry and food distribution. The introduction of transgenic products to the food market resulted in them becoming a controversial topic, with their proponents and contestants. The presented study aims to systematize objective data on the potential benefits and risks resulting from the consumption of transgenic food. Genetic modifications of plants and animals are justified by the potential for improvement of the food situation worldwide, an increase in yield crops, an increase in the nutritional value of food, and the development of pharmaceutical preparations of proven clinical significance. In the opinions of critics, however, transgenic food may unfavourably affect the health of consumers. Therefore, particular attention was devoted to the short-and long-lasting undesirable effects, such as alimentary allergies, synthesis of toxic agents or resistance to antibiotics. Examples arguing for the justified character of genetic modifications and cases proving that their use can be dangerous are innumerable. In view of the presented facts, however, complex studies are indispensable which, in a reliable way, evaluate effects linked to the consumption of food produced with the application of genetic engineering techniques. Whether one backs up or negates transgenic products, the choice between traditional and non-conventional food remains to be decided exclusively by the consumers.
For years, the human beings have tried to improve everything around them. The food does not escape to this reality, and that is the reason why today a new kind of it is found in supermarkets. This new type of food, is employing the genetic engineering to change its original characteristics, in order to improve it. However, it is important to know what we are eating and this brings us a question: is that food really good for us? Although the use of this techniques in food could have many different benefits for health and for the agriculture industry, they can also present several potential disadvantages.
Genetically Engineered Plants and Foods: A Scientist's Analysis of the Issues (Part I)
Annual Review of Plant Biology, 2008
Through the use of the new tools of genetic engineering, genes can be introduced into the same plant or animal species or into plants or animals that are not sexually compatible-the latter is a distinction with classical breeding. This technology has led to the commercial production of genetically engineered (GE) crops on approximately 250 million acres worldwide. These crops generally are herbicide and pest tolerant, but other GE crops in the pipeline focus on other traits. For some farmers and consumers, planting and eating foods from these crops are acceptable; for others they raise issues related to safety of the foods and the environment. In Part I of this review some general and food issues raised regarding GE crops and foods will be addressed. Responses to these issues, where possible, cite peerreviewed scientific literature. In Part II to appear in 2009, issues related to environmental and socioeconomic aspects of GE crops and foods will be covered.
Genetically Modified Food Controversies: A Reveiw
2015
This study was conducted at University of Gujrat during 2014-2015 as a term paper for Master of Philosophy. The data regarding genetically modified food controversies reviewed and compiled as a review paper from more than 40 published articles of international reputed journals, Annual / Environmental Reports of recognized organization and e-books. The study was carried out with the objectives to examine some reasons that are behind the genetically modified controversies and provide a better idea of what a genetically modified food is and how it affects human beings. This review paper includes various controversies regarding genetically modified food, positive and negative impacts of GM food towards mankind and environment, consumer attitudes to genetically modified food and its future prospects. It was exposed that food produced by conventional means or through genetic modification, is never assured to be completely safe. Just as with traditionally produced food, genetically produce...
Genetically Modified Foods: Promises, Challenges and Safety Assessments
2017
Background and Objective: Application of genetically modified organisms in the agriculture sector and food industry began since last years of 20th century. Since then this technology has become a central part of the broader public controversy about the advantages and safety of these products. This article has tried to review aspects of these types of organisms and foods.Results and Conclusion: Genetically modified technology has potential to overcome agricultural problems, such as biotic and abiotic issues by enhancing pests and herbicides resistance, drought tolerance, fast ripening, and finally enhancing yield and nutritional quality. Besides these revolutionary advantages, during the last decades some potential human, animal and environmental risks have been taken in account for these organisms or foods. However, no scientific evidence exists adequately about their harmful human or animal effects, and also, some new scientific and management methodologies (new technologies and re...
Genetically Modified Foods Review
New biotechnological methods have been recently used to improve the quality and quantity of foods in our globalized world to meet the demands exponentially increasing world population. Recombinant DNA technology help the scientists to transfer desirable traits more rapidly, predictably and precisely than the previous conventional methods. Since the mid-1990"s, genetic modification techniques has flourished rapidly that can help to boost agricultural productivity, but the technology is not fully understood by many of the consumers till date. There is a growing concern that introducing foreign genes into food plants may have an unexpected and negative impact on human health. By inserting genes from organisms which have never been eaten as food, new proteins with unexpected functions are introduced into the human and animal food chains. Many GM crops contain genes which provide resistance to commonly used antibiotics such as ampicillin, which could be passed from food to bacteria in the guts of humans and animals. Besides, the process of growing plant cells into GM plants may create huge number of mutations throughout the genome which can have their multiple interacting effects. Viral genes that are generally inserted into some disease resistant crops generally produce viral proteins which may suppress the immune system of human body against viral infections, particularly in the gut region. The gut microorganisms can produce large amounts of potentially harmful proteins if the viral genes can get entry inside these organisms. The new varieties of genetically modified seeds can increase the price of seeds, which can raise the question of affordability of the poor farmers of the developing countries. The terminator technology is increasing the dependency of the farmers on the multinational companies and can eventually destroy the indigenous seed varieties. These new technologies have triggered many questions regarding bioethics, human rights and food security, and most of them remain unanswered.
A Review on Genetically Modified Organisms and Foods- Perspective and Challenges
The ratio of the human population and the quantity of the eatable items are inversely proportional. The quantity of food items is decreased due to certain reasons such as, environmental conditions, unavailability of the water for farming, less income of farmers etc. The principal problem, concerning with GMO (Genetically Modified Organism) is the less information available in the public domain. Still the method for development of organism is bizarre for the public. Considering it, this compilation is aimed to sketch out the pitfalls for the implementation of GMO in the real world, and the advantages of GMO for the betterments of human society are listed. This overview will provide the detail information about the listed problems and shed off the myths and also open up the new paths to bring out the solution for the available problem in the area of genetically modified organism.
