The Bottom Line
The good news is that all genetically modified food is examined and studied by the United States Department of Agriculture, Environmental Protection Agency, and the Food and Drug Administration for toxicity and allergens before making its way onto grocery store shelves. And despite the fact that some studies have pointed to potentially negative effects, these three agencies, plus a number of additional studies, have determined that GMOs are safe to eat. The drawback: These crops are relatively new—emerging in the mid-1990s—so we'll have to wait to learn if there are any concerning long-term impacts.
