What are genetically modified (GM) organisms and GM foods? Genetically modified organisms (GMOs) can be defined as organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination.
The primary objectives of genetically modifying food products are to increase yield and increase resistance to a pest, in animals and plants respectively. Although some genetically modified foods have already been approved and passed to be safe as their traditional counterparts, their continued production is still very controversial.
Although some genetically modified foods have already been approved and passed to be safe as their traditional counterparts, their continued production is still controversial. Did you know that despite their seemingly wonderful characteristics, it is believed that several disadvantages may result from genetic engineering?
The production of GM foods imposes high risks to the disruption of biodiversity. This is because the “better” traits produced from engineering genes can favor one organism. Furthermore, the introduction of genetically modified organisms can eventually disrupt the natural process of gene flow. So what does this mean?
It is known that the main concerns about adverse effects of GM foods on health are the transfer of antibiotic resistance, toxicity and allergenicity. There are two issues from an allergic standpoint.

Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism.

The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
Perceived disadvantages of genetically modified crops may be grouped into five categories: 1) potential impact on non-target species; 2) potential for increased weediness; 3) increase in toxin levels in the soil; 4) exchange of genetic material between the transgenic crop and related plant species; and 5) selection for ...

Traditional genetic modification methods that have been employed—particularly for microbial starter cultures—include selection, mutagenesis, conjugation, and protoplast fusion, the last of which is analogous to somatic hybridization in plant systems.

There are some that describe GM crops as "Frankenfoods", deliberately termed to imply that they pose a risk to human health and the environment. ... First, there was no scientific evidence associating GMOs with higher risks for the environment or for food and feed safety than conventional plants and organisms.
The science seems to be pointing toward the safety of GM crops, at least as foods. It's good to remember that "the adoption rates for GM soya stand at 88 per cent in Brazil, 93 per cent in the U.S. and 100 per cent in Argentina," as Paterson remarked in his June speech.
An Argentine farmer stands by his field of trangenic soy, designed for resistance to drought and salinity.

It is one thing to turn on your plasma TV or talk on your iPhone; it is an entirely different proposition to knowingly ingest something that has been modified in the lab. It is no coincidence that reactions for and against GMOs are often radical and polarized.
Following mounting evidence that Bt cotton is behind a number of farmer suicides, the India Supreme Court has recommended a 10-year moratorium on all field trials of GM foods. So, the issues are complex. They are likely to become even more so in the coming years.
No evidence of human health problems associated specifically with the ingestion of these crops or resulting food products have been identified, but concerns have been raised about the potential for transgenic food products to cause allergic reactions or produce toxic compounds.
The primary objectives of genetically modifying food products are to increase yield and increase resistance to a pest in animals and plants. Although some genetically modified foods have already been approved and passed to be safe as their traditional counterparts, their continued production is still controversial.
In the continuing battle for hunger, food production has gotten more technologically improved through the years. Hence the production of food that is said to be “Genetically Modified,” like the ones previously mentioned. Recombinant DNA technology or genetic ...
Another reason is when the inserted gene is not generally accepted by the recipient organism because it interferes with its metabolic pathway. Thus, by eating such foods with toxins, the possibility of ingesting the toxin and being harmed by it may happen.
In humans, the number one most common side effect of consuming GM foods is allergic reaction . This allergic reaction happens when a certain protein/allergen present in the GM crop enters the body and stimulates an immune response. As alluded to earlier, genetically modified foods are created by inserting foreign genes into an organism.
Disruption of biodiversity. Biodiversity. The production of GM foods imposes high risks to the disruption of biodiversity. This is because the “better” traits produced from engineering genes can favor one organism.
As you can see, the disadvantages of GM crops are much larger than simply harming our health. Regarding its environmental effects, toxicity is a huge issue concerning GM crops. One particular example is the Bt Corn (Bacillus Thuringensis Corn), which is widely known for its pest controlling ability.
In addition to health and environmental issues, the production of GM crops and animals has become the center of social and ethical debates. And at present, it is still challenging to decipher their long-term effects, hence, leaving consumers the fear for safety.
The most comprehensive study of the health risks of GMOs was a 2016 study conducted by the National Academy of Sciences entitled, “Genetically Engineered Crops: Experiences and Prospects.” In the report, researchers took a good hard look at the environmental and social impacts of GMOs, whether they reduce pesticide use, and if they are safe to eat.
In the United States, there are at least 3 regulatory bodies that ensure that the foods Americans eat are safe: the U.S. Food and Drug Administration (FDA), U.S. Environmental Protection Agency (EPA) and the U.S. Department of Agriculture. Each of these bodies regulates a different aspect of the food chain process, ...

Genetically Modified Foods are NOT Safe to Eat — The No Camp. One of the leaders of the no camp is the Institute for Responsible Technology (IRT), who in a two-part blog series goes into great detail about “The Great GMO Cover-up.”. The blog contains claims that the glyphosate-based herbicide Monsanto uses in Roundup blocks mineral absorption, ...
GMWatch’s blog is titled “No, ‘science’ has not confirmed that GMOs are safe to eat,” points out that the 22-member committee that conducted the NAS study was composed of at least 12 individuals either employed by global biotech firms or from organizations funded by them.
The Non-GMO Project, a non-profit organization with the mission to increase consumer awareness about GMOs, also cautions against blanket GMO safety statements. They cite a study that found there are just as many research groups raising concerns about GMOs as groups finding them as safe and nutritious as other foods.
To support this claim, a recent study published in the journal Environmental Health Perspectives found that “low levels of the weed killing chemical glyphosate and the glyphosate-based Roundup product can alter the composition of the gut microbiome in ways that may be linked to adverse health outcomes.”.
