Genetically modified foods or GM foods, also genetically engineered foods, are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits than previous methods such as selective breeding and mutation breeding.〔(GM Science Review First Report ), Prepared by the UK GM Science Review panel (July 2003). Chairman Professor Sir David King, Chief Scientific Advisor to the UK Government, P 9〕 Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its Flavr Savr delayed-ripening tomato. Most food modifications have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil. Genetically modified crops have been engineered for resistance to pathogens and herbicides and for better nutrient profiles. GM livestock have been developed, although as of November 2013 none were on the market. There is general scientific agreement that food from genetically modified crops is not inherently riskier to human health than conventional food.〔American Association for the Advancement of Science (AAAS), Board of Directors (2012).

According to the World Health Organization, "Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally...".〔(【引用サイトリンク】title=Food, genetically modified )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Genetically modified food」の詳細全文を読む スポンサード リンク
