https://gmo-awareness.com/shopping-list ... ee-brands/The two simplest ways to avoid GMOs are:
1) Buy certified organic / USDA Organic products, which cannot intentionally include any GMO ingredients. Read more about organics and GMOs here >
2) Look for products bearing the “Non-GMO Project” verified seal, which indicate these products went through a separate certification process.
I don't know if it's possible to be completely GMO-free if you rely on the grocery store, however I think most of us can cut down on our consumption of pesticides/GMOs.
