October has always been a month filled with food, from the harvest season to the bellyaching Halloween indulgences. But it now also marks another monumental observation: Genetically modified foods, or rather, the lack thereof. October is officially Non-GMO Month (as if any month isn't!).

The use of genetically modified ingredients in our food has never before been such a concern, with as much as 80 percent of processed foods containing GMOs. And if you're just finding out about the risks and dangers of these controversial foods now, you're not alone. Many Americans are waking up to the reasons for avoiding GMOs, and there are some easy tools to help you along the way. Check out these mobile phone apps that can steer you clear of GMOs.
