Yes indeed, most Americans do eat GMOs every day!Maarten J. ChrispeelsArticle first published online: 15 JAN 2014While teaching a course on Crop Biotechnology at Huazhong Agricultural University (Wuhan, Hubei Province, China) this past October, I was asked by one of my students if it is true that American farmers grow genetically modified crops (GMOs) only for export, and that GMO-foods are not sold in the USA. The student implied that Americans thought that such crops were “good enough” for developing countries but not good enough for themselves.Americans have been eating GMO-foods for 17 yearsNeedless to say, I was dumbfounded by this question because Americans have been eating GMO foods since 1996 and I could not imagine where this idea came from. By asking around, I discovered that this information is publicized extensively by TV personalities and on social media. Apparently, several Chinese reporters traveled to the US and enquired in supermarkets whether they sold GMOs, whether people knew that they were eating GMOs and whether they were for or against GMOs in the human food chain. They received variable answers, of course. Some Americans don't care, many don't know and some object to eating GMOs. Some opinion polls show that many Americans would like GMO-containing foods to be labeled. However, it is known that people's answers to questions in opinion polls are highly dependent on how the questions are posed and whether an explanation is given before the question is asked (PEW2013
