GMOs, or genetically modified organisms, are a hot issue, especially when it comes to labeling. So what is a GMO? It is a plant or animal that been genetically altered or modified to increase its ability to resist pests, produce more food and grow in non-native environments. Several companies do this to increase profits.

Research from the Mayo Clinic shows the harmful effects of GMOs may include antibiotic resistance, decreased nutritional value, increased food allergies and toxicity.

Many people believe all food with GMOs in it should be labeled as such. California voters in 2012 rejected Proposition 37, a statute that would have required labeling of genetically engineered food, with some exceptions. It would have banned the practice of labeling genetically engineered food with the word “natural.”

When it comes to large companies, which ones support labeling of food with GMOs? Here are five companies that support GMO labeling:

1. Chipotle

Chipotle’s vision is “Food With Integrity.” It claims its food is all natural and even has a link on its website supporting GMO labeling and defining exactly what it is. I’ll take black beans – hold the GMOs, please.

2. Organic Valley

Self-declared “organic and farmer-owned” Organic Valley strongly opposes GMOs. It too has a link defining exactly what GMOs are and how bad they can be. It is companies like these that give hope to us carnivores and milk drinkers.

3. Amy’s Kitchen

Amy’s has always brought us natural and organic foods that taste great. It does not use GMOs in its foods because it says it is “uncertain of their safety,” which is exactly the point of GMO labeling. Amy’s helped found the Just Label It! campaign. People need to know what they are eating.

4. Earth Balance

“No, No, GMO” it reads at the top of the Earth Balance Non-GMO Commitment. Earth Balance partnered with the Non-GMO Project, a nonprofit working to spread the word and take action against GMOs and their harmful effects. It also works with the Institute for Responsible Technology to try and create a tipping point where people do not buy products with GMOs. The hope is this will diminish demand.

5. Numi Organic Tea

Almost two years ago, Numi became the first company to get approved to use the Non-GMO Project’s verified seal. Apparently, many tea bags industry wide are made with genetically modified corn. Packaging can be a huge part of GMO issues, depending on what was used to make the packaging.

The next time you go to the grocery store, show your support of GMO labeling by purchasing from one of these brands.
