Are GMOs Bad For Your Health? - The Dr. Hedberg Show

GMOs, or genetically modified organisms, are one of the most contentious topics in the world today. We should however, consider the following questions: What do we really know about them? Are these concerns justified? People are so passionate about this issue that some misguided individuals have actually rioted and vandalized crops in Oregon, Australia, the United Kingdom and the Philippines. This mob behavior is similar to the burning of women at the stake for committing imaginary crimes like witchcraft.
Unfortunately, public opinion oftentimes has absolutely nothing to do with scientific fact. A Gallup poll showed that 48% of respondents actually believe that foods produced using biotechnology pose a serious health hazard, compared to 36% who think that they do not.
GMO labeling is a hot issue. Currently, laws are being passed around the country requiring labels on all GMOs with Vermont being the first state to enact such a law.
What is a GMO?
Basically, scientists extract DNA from an organism, modify the DNA, and then incorporate it into the genome of the same species or a different one. This transfer of modified DNA can be accomplished by using a “gene gun” to inject DNA-coated metal pellets into the plant cells, or by just using bacteria for delivery.
Another type of GMO is created by turning off a gene that is normally expressed without introducing a new gene.
Cisgenic GMOs are achieved by introducing genes from closely related species, and transgenic GMOs are the result of genes from distant species crossing over to other kingdoms of life. For example, taking a gene from a bacteria and inserting it into a plant will produce a transgenic GMO.
Both of these types of genetic modifications actually occur in nature on a regular basis, so they are nothing new and completely “natural."
GMOs are truly one of science's greatest achievements that have yielded many benefits to humans other than food. Two very important achievements include insulin that diabetics inject themselves with to regulate blood sugar to keep them alive and growth hormone that is used for kids with rare genetic disorders that prevent them from growing normally. Both of these hormones are produced from GM bacteria.
How long have GMOs been around?
Did you know that genetically modified foods have been around for the last 10,000 years and that most of the food
