There has been a lot of talk on both sides about possible benefits of non-GMO food. Non-GMO's include organically grown fruits and vegetables, grass-fed cattle, and wild caught fish. Some say there is evidence of long-term harmful effects of GMO's while others say there is no benefit to spending extra money for non-GMO products. It's also hard to tell if the people writing the articles have their own self interests in mind. Thoughts?
