The National Academies experts reviewed the relevant studies and solicited huge amounts of feedback. The upshot? “No differences have been found that implicate a higher risk to human health safety from these GE foods than from their non-GE counterparts,” they concluded. They based their findings partially on a comparison of European countries, where genetically engineered crops generally are not used, and the United States, where they are plentiful. They could find no significant differences attributable to genetically engineered crops, across a range of diseases and disorders.
