The advantage of Genetically modified food,1,4,Genetically modified food(GMF) refers to the food using genetic engineering (GM) technology in the species genome to embed in heterologous gene,including transgenic plants,genetically modified animal,and genetically modified Microbial food.,The advantages of genetically modified food,1.High nutrition,An estimated 30% of the world population is in iron deficiency,through transgenic technology,the content of iron in rice will increase,2.Resistant,More sturdier and robust Being resistant to drought, disease and pests.,3.Improving taste,Some fruit and vegetables are nutritious, but taste is bad.Through genetic engineering, scientists can produce more delicious plant products,which is beneficial to human and the development of food industry.,4.Improing food quality,It is difficult to keep the fruit too long,the genetic engineering,for one,makes it possible to extend storage time,for another,increase the drought resistance of plants in some areas that is out of water supply.,5.Stoping hunger,Over 20% of these people are suffering from poverty and hunger. GM foods are easier to grow and bring higher yields.,6.Friend environment,GM foods are good for the environment.
