This is not true. Soy has been shown to make its way mostly unchanged into the egg from a hen that eats it. Gluten, possibly too. Soy and wheat are both almost always genetically modified in the United States. Everything that happens to the chicken happens to the egg in some way. GMO feed is the same as hormones or antibiotics, if the hen gets it, so does her egg.
Look up the Monsanto company, the one behind all of this. They create GMOs, pesticides, everything from DDT to Agent Orange to hormones given to cows. Every time you buy GMOs you support them. Monsanto is also involved in all kinds of political lobbying. A lot of people are convinced the USDA is practically run by Monsanto.
GMOs are given more pesticides than traditional crops. For example, Monsanto makes a weed-killer called Round-Up. The problem with Round-Up is it is so toxic is doesn't just kill weeds, it kills crops too. Monsanto genetically modified an alfalfa crop, calling it "Roundup Ready" alfalfa so that it can be sprayed with pesticides over and over again without dying.
Also, GMOs are legally owned by Monsanto (there are other companies, but Monsanto is the big one here in the US). Let's say there are two cornfields by two farmers. One is GMO, the other is not. The GMO pollinates the other corn. What happens? Monsanto sues the other farmer for "stealing" their GMOs. It has happened before.
Some GMOs have their nutritional value tampered with. For instance, GMO wheat has higher levels of gluten than any other wheat, which makes it damaging for some people's digestive systems.
You need to look for independent studies. Independent studies have shown rats fed GMO corn developed cancers while rats fed regular corn did not. Most countries have banned GMOs completely for health reasons.
I am happy to provide more info and sources if you would like. This is just a quick overview of reasons people choose to be GMO-free.
Not sure where to start, virtually every statement above is completely false. Do you have any concept of how digestion works? Proteins are entirely broken down into their component amino acids when eaten, they do not "pass on" to eggs or anywhere else, they are used by the body to provide energy and build other proteins.
The demonization of Monsanto is a tired trope that is endlessly recycled regardless how many times the inflammatory statements have been disproven. GMO crops do not get more herbicides or pesticides than conventional or even organic crops. This has been proven repeatedly, yet like an unsinkable rubber duck, these dumb myths keep popping up because people are more interested in perpetuating fear than understanding what is actually happening. I'm no fan of some of Monsanto's business practices, and there is a need for string regulation to keep the food supply safe, but the regulation needs to be based on evidence, not fear and doubt.
The tumor study mentioned above us another pile of nonsense. Seralini's study was poorly designed, poorly controlled and focused on rats with a well known propensity to develop tumors regardless of their diet. There was no substance to the study at all, and it was subsequently withdrawn by the publisher. GM corn has been fed to people and animals for years, with no detrimental effects.
The countries that have banned GMOs have done so in the absence of any scientific evidence that there are any safety issues. They are pandering to mob mentality, spurred on by a public that is far too willing to listen to scare tactics and not interested in any evidence that doesn't reinforce their superstitions.
The GMOs currently approved all have an extensive proven track record of safety. Some have failed, not because of inherent dangers of the technology, but just because they fell short of market demands for flavour, shelf life, etc. Some revolutionary product, such as Golden Rice, have the potential to spare millions from malnutrition, but are stonewalled due to fearmongering.
GM technology needs to be treated carefully, like anything impacting food supply and people's health, but decisions need to be based on real science. The only statement I agree with is that studies should be independent, but they also need to be properly designed with adequate controls, proper sample sizes and good peer review.
