Download file to see previous pages As per the current scientific situation, most foods that are as a result of genetic modifications come from plants, but as time goes by, attempts are being made in order to come with foods from plants or animals that contain microbial genes and improved characteristics (Kim, 2009).
Most of the genetically modified food crops are produced so as maximize on their yield while at the same time allowing for introduction of resistance genes that help in surviving during infection with diseases. Other genes may also be introduced so as to increase tolerance of the plant to herbicides while at the same time having high yields. It is prospected that this genetic modification at some point will be aimed at making changes on the nutrient content of the genetically altered foods and at least minimizing the potential of some foods to cause allergic reactions. It is however important to perform assessments of all genetically modified foods before they are brought into the market for human consumption since any mistakes done during the process of generating the GMOs may have a fatal effect on huge numbers of people (Kawata, Murakami & Ishikawa, 2009).
The first step in the process of manufacture of genetically modified foods involves isolation of the specific genes of interest from heir well-known sources. It is therefore essential that prior knowledge on the structure, role and positional location of the particular gene required for the unique traits is available. Such a trait or genetic characteristic for example may be the trait of drought resistance or resistance to attack by insects. This step is followed by insertion of the isolated gene of interest into a selected vector and in most cases the vector used is the bacteria Agrobacterium tumefaciens. The gene insert that contains the gene of interest is inserted into the plasmid of the vector by use of an alternative in the various ...Download file to see next pagesRead More

Genetically Modified Food

... can be fed genetically modified food because it is inexpensive and it does not take much effort to produce it. This paper will shed more light upon how genetically modified food can save countless lives not only in Africa but also all across the globe. There is very wrong perception of the rich people that there is no food shortage in the world and this is because they have all the luxuries in the world, but they have just noticed the sharp increase in food price. However, food is becoming a scarce resource and this increase in prices is a result of food crisis which is one of the most important global issues. According to The Oxford Committee for Famine Relief (OXFAM), there are 967 billion people who do not have enough amount of food...

Genetically Modified Food/Organisms

...?Genetically Modified Food/Organisms Background of the Issue “Between 1997 and 1999, gene-modified (GM) ingredients suddenly appeared in 2/3rds of all US processed foods.” (Butcher). Flavr Savr, the first commercially grown genetically manipulated food tomato was released in the market in 1994 without any labeling. “The first commercial food product developed from gene slicing (a term for a type of genetic modification) was the Flavr Savr tomato.” (Schneider and Schneider). The tomato was produced through the concept of genetic modification where it could naturally ripen on the vine and could be firm enough to withstand the shipping after it is harvested. It was developed as a “better” version of the normal regular tomatoes...

..., and their potential to cause diseases. The high cost and lack of awareness among farmers are factors that might hinder the growth of food industry that has otherwise immense potential of growth. This report based on primary and secondary research discusses food industry’s growth in relation to a range of technological, economic, and political factors. Primary survey conducted with focus group interview was based on 4 respondents’ groups including company executives, government agencies, investors, and people. Two genetically modified food making companies’ executives were asked questions. They emphasized upon the role of technology and market dynamics...

...Critical review on the paper "Evaluation of the sensitization rates and identification of IgE-binding components in wild and genetically modified potatoes in patients with allergic disorders" The ABIC Manifesto, in large extend, explains the necessity of genetically modified (GM) foods. With the growth of the human population, which is "estimated to reach 9 billion by 2040, and with the small but steady decrease of agricultural land (around 70 000 km2 annually)"3, the GM food plants seem like the most effective measure to counter these problems. Nevertheless, there have been serious objections to the manufacture and distribution of GM foods, especially since "1993, Pioneer Hi-Bred International developed a soybean variety with an added...

...compared to natural food. This means the losses incurred to farmers and other people who are involved in the same can easily be averted. Research also goes to show that genetically modified food is also resistant to herbicides which natural food can never be. These are some of its advantages but there are disadvantages too which must be considered to make its case even. Last year a laboratory study was published which showed that pollen from B.t. corn caused high mortality rates in monarch butterfly caterpillars. Monarch caterpillars consume milkweed plants, not corn, but the fear is that if pollen from B.t. corn is blown by the wind onto milkweed...

...their resistance towards herbicides or improve their nutrition value. The sale of genetically modified food started in 1994 and of late it has expanded in many areas with the corn, cotton seed oil, soybean, and canola plants being demanded in many countries. According to scientists, genetically modified foods do not pose high risks as compared to conventional foods. However, opponents argue that the foods raise safety issues, environmental concern as well as economic issues. While it takes time to breed conventional plants, genetic engineering ensures that the breeding process is not...

...adopted complex measures by integrating the laboratory with breeding, and narrowing down to the building blocks of such attributes; the genes. As such, various methods of genetic modification, alteration, and improvement have developed organisms that are an improvement of the already existing organisms. The improvement is in terms of the rate of growth, resistance to more harsh conditions, and productivity. This has been integrated with food production, with the widespread of genetically modified foods. As much as such developments promote the wellbeing of individuals through reduction of food insecurity and increasing the nutrient...

Labeling genetically modified food

However, plans are already underway to make labeling of genetically modified food mandatory. This intention became apparent through the introduction of two bill in senate; the HR 3377 and S 2080-Genetically Engineered Food Right to Know Act, according to Teisl et al. (par. 2).
In the United States, certain crops are commonly modified genetically during processing. Some of the products that are genetically modified in while growing include cotton, corn, canola, and soybean. However, the controversy comes in because most processed food products in the U.S. contain either corn or soybean ingredients. As such, it is estimated that about 70 percent of processed foods in America contain genetically modified ingredients. This raises...

Advantages of Genetically Modified Food

...Advantages of Genetically Modified Food Introduction With global population growing at an alarming rate, it has been predicted that by the year 2025there will be a severe crisis of cereals. It is estimated that there will be annual shortage of 68.5 million tones. The concept of genetically modified food (GMF) can serve as a solution to this grave problem. Many countries like the U.S., China, South America and Africa are already cultivating genetically modified crops on a large scale. In spite of its virtues in the food market GMF is surrounded by controversies, especially in Europe, regarding its impact on human health and environment (Purchase, 2005, p.19). However, the benefits of GMF clearly outweigh any such concerns. For any emerging...
