Why GMO Foods Are Not Bad for Your Health

The words "genetically modified" or "genetically engineered" may sound scary, but there really is a great potential for saving lives and improving health by making these changes to the plants that provide foods we eat every day. 

Genetically engineered foods (also called genetically modified organisms or GMOs) are not bad for your health. A lot of people are leery of GMO safety, but in reality, they've been around for a long time, and they're heavily researched.

According to the United States Food and Drug Administration (FDA), at least 81% of soybeans and 40% of corn produced in the United States are genetically modified. You've probably been consuming GMO foods for a long time.

A Lot Like Regular Breeding but Faster

Humans have been doing this to their foods naturally for many years. The old-fashioned way to genetically modify food crops is to cross-breed plants that show the characteristics the farmer wants to improve. Over several seasons, the preferred traits will become more evident. Unfortunately, this type of modification is a slow and somewhat limited process.

Genetically engineering food crops goes a few steps beyond the old-fashioned process of cross-breeding. Plants can be genetically modified so that they are more resistant to pests or altered in such a way that the crop plants are resistant to weed-killers. That means stronger weed-killers to be applied to the plants.

Genetically engineering isn't limited to making plants easier to grow. Plants could be modified to improve their nutrition content or enhance their safety.

For example, some plants that typically contain significant amounts of calcium could be genetically modified to reduce the number of oxalates they also produce. Oxalates normally bind some of the calcium and make it unavailable for absorption in the body. This modification to reduce the oxalate would allow more calcium to be absorbed.

Another possibility might be to modify peanuts so that their proteins are less allergenic; this change could potentially save the lives of the people who suffer from this dangerous allergy. Of course, it would be difficult (and scary) to test this during development.

GMOs Just Are Not That Scary

The idea of genetically engineered foods makes some people nervous. A quick search on the Internet will bring sites from various groups who are concerned about the safety of growing and eating genetically modified foods.

Some areas of concern are:

  • The potential for unknowingly creating allergens
  • Possibly spreading pesticide resistance to wild plants
  • Possible toxicity to animals
  • The idea that these foods are unnatural
  • Should genetically engineered foods be labeled?

Genetically engineered plants are researched for safety before the seeds are made available to farmers. The United States Department of Agriculture (USDA), the FDA and the Environmental Protection Agency (EPA) are all involved in the regulation of genetically engineered plants, including its impacts on plant health, the environment, and food safety.
