Genetically Modified Organisms (GMOs) became a hot topic in 2012 when the people of California had the chance to vote on Proposition 37 in November.

Proposition 37 would have required labels on food that contained such products.

Let’s look at the facts about GMOs, whether they’re good or bad, so you can decide for yourself.

GMO Food: Benefits

So what are the benefits of GMOs? According to the Office of Science at the U.S. Department of Energy, one of the pros of genetically modified crops is a better taste, increased nutrients, resistance to disease and pests, and faster output of crops.

The Food and Agriculture Organization of the United Nations also says that farmers can grow more food on less land with genetically modified crops.

Genetically modified animals have certain genes inserted into their genomes so that they can produce ‘better’ milk, eggs, and meat. These animals also are expected to have a higher resistance to disease and overall better health, with better natural waste management. In theory, genetically modified crops and animals will also be more environmentally friendly because they conserve water, soil, and energy.

The Food and Agriculture Organization of the United Nations states that one of the positives of GMOs is that farmers can produce more nutritious food. Many foods are in the works for bio-fortification for this reason. Rice, for example, feeds 50 percent of the world’s population, so genetically modifying rice to have more vitamin A would reduce vitamin A deficiency in developing countries.

But what happens to these plants and animals that have been genetically modified? What happens when we eat these foods? Unfortunately, no one knows for sure what happens, though evidence is mounting that genetic modification may not be a good thing.

Genetically Modified Foods: Controversy

The Office of Science at the U.S. Department of Energy also lists some of the controversies associated with genetically modified foods. One of these controversies are the potential health risks, including allergies, antibiotic resistance, and unknown effects. Other negatives that stem from GMOs is that scientists are tampering with nature by mixing genes and no one knows what this is doing to the animals or the environment.

Phil Damery and colleagues at Iowa State University describe the risks of genetically modified foods to humans in their paper, “The Debate on Labeling Genetically Modified Foods.” Damery says that the agricultural food industry claims that GM foods are tested rigorously, but the food companies conduct all their own testing. The U.S. Food and Drug Administration never reviews the studies, just the conclusions that agricultural food companies provide to the FDA. Damery states that, when studies were conducted by non-agricultural  food organizations, they found serious health risks with GM foods and the way they tested for safety.

    In a couple of weeks I will be 73 years old. I recently noticed that most of the processed foods contain health reducing contents, especially GMO ingredients.

    As a believer in GOD, I do not want to consume foods that have been tampered with genetically by non-believing scientists. GOD doesn’t need any help to improve HIS perfect creations. Since most people no longer grow their own foods, people should be made aware of the ingredients included in their food.

    I am not so smart to be able to discover these items without a little help. As a result, I never purchase but a few canned or processed foods. Additionally I purchase organic foods where possible, yet believe I am deceived many times by the use of tricky or deceptive advertising.

    I believe all commercially produced food should be boldly identified as GMO or non-GMO. There should be no way for producers by using trickery of words to include GMO organisms of any kind into food identified as non-GMO. I also believe that if GMO food producers have nothing to hide, this is a reasonable requirement.

    I personally believe that only people who are starving will agree to purchase GMO foods or, illiterate people who cannot read the contents.

    My food choices have reduced to a level that I have little choice anymore. Still I will eat the same foods over and over and over, before I will ever pay money for foods produced by lust and greed motivated producers.

    Any food with high fructose corn syrup, monosodium glutamate (or their many disguised names), GOM foods, or those that are injected with hormones or antibiotics should be required to be boldly advertised.

    Whenever a group of people want something put into effect, it is amazing how many pros they can find and how few cons. Yet, frequently, when all is said and done, it is the cons we see and not so much the pros.

    From the reports I’ve read, that were not written by Monsanto, GMO foods were shown to have less nutritional value than organic foods. Insecticides such as Roundup & those that the produce grow themselves from the inside out are clearly shown to cause tumors, reproductive problems, autism, allergies, super bugs, soil depletion, use of stronger pesticides, etc. Monsanto’s shady business methods are putting farmers out of business worldwide with their bullying tactics & their products not living up to Monsanto’s claims.

    Oh, wow. You really squirmed around to make it look like the negatives are legit. That “1989 a genetically modified dietary supplement of tryptophan” was not a genetically modified dietary supplement at all, for example. It was created, like tons of other things, using GM bacteria (like the way we create insulin to save the lives of diabetics). The batches of tryptophan that killed people contained KNOWN TOXINS from the way they were made, but they were not properly tested. There was not some strange unknown created by GM here… it was known, discoverable toxins. But proper testing wasn’t done. You know, how SPINACH has killed people when it was tainted with known toxins like e-coli. Your attempt to pretend to be even handed by opening with a weak defense of the benefits of GM is more than shown to be a lie by the way you handled the tryptophan incident. Shame on you.

    Walk down the aisles of your local supermarket and you’ll find floor-to-ceiling shelves packed with food boasting nutritional benefits: whole grains in cereals, omega-3s in eggs, lycopene—that powerful antioxidant—in ketchup. But there are other ingredients hiding in these products, and most of us don’t even know they’re there. They’re called genetically modified organisms (GMOs), and they’re in 80% of the processed food on grocery store shelves—and a handful of whole foods as well, with perhaps more on the way soon.
