IntroductionThe GM food stands for the Genetically

modified food. The GM food are foods derived from

genetically modified organisms(GMOs).GMOs have had specific changes introduced

into their DNA by genetic engineering techniques.

Scientists always want to produce some kinds of food that can combine many useful properties together.

PropertiesThe GM food’s DNA has been

changed, may be added or deleted some

gene segments.The traits of the food must have been changed.The GM food may contain some

Latest Situation--AdvantagesFaster growth productivity increases provide enough food pests and insects resistance avoid usage of pesticides and insecticides environment friendlyHerbicide tolerancemore nutritional value Longer shelf life shipped long distances

Latest Situation--Disadvantagesend food diversityReduced effectiveness of pesticidesSuperbugscause an allergic reactionUnknown effects on human healthPlay the role of ‘God’

Latest Situation--Development1994 first apply the GM technology to foodpopular GM food can be found everywhereGM crops are allowed in China European Union: some crops

PredictionMore GM food developedPeople will explore more to GM foodPeople will be more open to GM foodBut still many concerns to GM foodGM food cannot replace traditional food
