GMOs, also known as genetically modified organisms, are created by injecting the DNA from one species into another species, creating genetic combinations that cannot occur in nature or through typical crossbreeding methods. For example, genes from an arctic flounder (which has natural "antifreezing" properties that protect it from the frigid waters) may be injected into tomato DNA to make a new breed that is more resistant to frost damage. It sounds like a sci-fi movie, but it’s reality. And, according to the FDA, over 75 percent of processed food in the United States may contain GMOs. Foods with genetically modified ingredients don’t have to be labeled, though, so you’re probably eating them every day without even knowing it.
