Pros and Cons of Genetically Modified Foods There is a great debate going on right now on the subject of genetically modified foods, or GMOs. For some, the idea of GMO food is a good one because the modifications allow crops to become resistant to drought and infestations, letting more people have more regular meals.

Foods derived from genetically modified organisms are called genetically modified foods or GM foods. Basically, it’s any plant or animal that has been modified through genetic engineering. Well, of course, but, in reality, we’re not yet eating any animal modified in such ways. Animals eat genetically modified crops, but that’s as far as we have so far gone. Not a bad thing; we quite like our chicken tasting like chicken. As for plants - whether fruit or vegetables - this rather controversial process works by modifying the plant’s genome to increase its size or crop yield. Feeling any more enlightened? Probably not. Let’s just say this: genetic engineering takes the DNA genetic makeup of one plant and sticks the genes for one or two beneficial traits into another plant. Find out how genetically modified foods are regulated in accordance with the Food Standards.
Well, as already stated, they can produce bigger crop yields. Absolutely nothing wrong with that, especially if the beneficiaries are countries desperately in need of food. Genetically modified crops are cheaper to growdespite the higher initial modified seed costs. It seems that modified crops are sturdier, standing up to more weather extremes and requiring less expensive pesticides and herbicides (that’s a good thing). Plus, they need less day-to-day TLC. Less people constantly tending the crops is a major cost-saving; a saving that may or may not find its way onto a supermarket price tag. It only gets better from there. Genetically modified food is, from all accounts, considered to be of a high quality, more nutritious food. Moreover, if a country’s diet is severely lacking in a particular nutrient, genetic modification is likely to help battle malnutritionwith fruit or vegetables that are high in exactly what is needed. Impressive, yet scary stuff. And it’s hard to deny there ar...
Genetically modified foods do have some disadvantages as well. Some of these include: People with allergies are a concern. With all this mixing and matching of genes, when is a cauliflower still a cauliflower and when has it become a cauliflower/broccoli hybrid. And what if you’re allergic to broccoli? Genetic modification blurs the boundaries of what people with allergies can eat and can’t eat safely. There are also concerns about how genetically modified food will affect the overall food chain. A pest that suddenly stops being even remotely annoying to a sturdier crop can die out and leave an important link in the food chain with nothing to eat. More concerning is the great unknown of genetically modified foods being responsible for gene transfer. A constant risk of GMO foods is that the modified genes of the organisms may escape into the wild. Brown University warns that herbicide-resistant genes from commercial crops may cross into the wild weed population, thus creating "superw...

Oct 29, 2013 · Genetically Modified Food (GMO) – The Good, The Bad and The Ugly. October 29, 2013. The debate continues whether genetically modified organisms are out to save the world or destroy it. But the argument from either side is far from cut-an-dry. Learn the backstory on a few of the most pressing issues.

A valuable alternative to tackle malnutrition Some plants are genetically altered to increase their nutritional status. GM technology has been adopted more rapidly than any other agricultural technologies. And now, this technology is used by 16 million farmers. Biofortification via genetic engineering strives to promote food sources for hundreds of millions of people by enhancing the nutritional quality of staple crops. The most obvious example is “golden rice.” Golden rice seems to be golden because it carries an enormous volume of provitamin A that our bodies can convert into vitamin A. Golden rice not only helps to cope with vitamin A deficiency and related diseases but also improves rice productivity. According to a research study published in the Journal of GM crops foods,some GM rice can enhance farm productivity, with yields per hectare 10 percent more for 40 percent of worldwide production. Scientists have also developed a new generation of potatoeswith enhanced nutritive va...
Plants can be engineered to produce proteins, vaccines, and some other pharmaceutical products. Although some are worried about the transfer of allergenic genes, scientists can use genetic modification to remove the allergen from products. In 2012, the FDA approved the first plant-produced pharmaceutical for the treatment of Gaucher’s Disease. Moreover, we can modify tobacco plants to produce therapeutic antibodies .
Herbicides and insects resistant GM crops can considerably simplify crop management and overcome crop losses, leading to increased yields. Compared to non-GM varieties, GM varieties of soybean, cotton, and maize produced 29.8%, 7.6%, and 19.8% higher yield, as shown in the table below. Table#1:Additional crop production arising from positive yield/production effects of biotech crops (Adapted from PG Economics, 1996-2007) Moreover, the Economic Research Service of the United States Department of Agriculture (USDA) noticed a significant relationship between increased adoption of herbicide-tolerant GM crop seeds and increased crop yields. The USDA reported significantly increased yields when farmers adopted herbicide-tolerant cotton and Bt cotton . Due to the enhanced productivity and efficiency gains, genetically modified crops have had a positive impact on farm income worldwide. In 2016, the direct global farm income profit was $18.2 billion. Over 21 years, between 1996-2016, f...
Tilling, the process of turning the soil, is a method to control weeds. Many of the positive environmental consequences of conservation tillage systems (reduced- or no-till) are well documented by the National Research Council [NRC]. The adoption of herbicide-tolerant soybean (HT soybean) has a positive and highly significant impact on the adoption of conservation tillage (reduced- or no-till) in the United States. HT soybean has decreased the number of tillage operations between 25% and 58% in the United States and Argentina . The introduction of HT soybean has also been cited as an essential factor in the rapid increase of no-tillage practices in Argentina. And the adoption of no-tillage practices in this region has allowed for wheat to be double-cropped with soybean, which has led to a significant increase in farm productivity . Technologies that promote conservation tillage practices decrease soil erosion in the long term and fundamentally encourage soil conservation while...

Nov 20, 2020 · The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
May 11, 2011 · Genetically Modified Food (GMF) means any food containing or derived from a genetically engineered organism . Describing biotechnology methods is beyond the scope of this paper however, it is informative to only name some of the vastly used techniques in creating GM crops: Agrobacterium has been used as an intermediate organism for transferring ...
