The GMO foods stands for Genetically Modified Foods. Like humans the organisms, plants and animals have the genetic material which is nothing but the DNA.When scientists alter the genetic material especially in plants it is called genetically modified foods or food crops. It will enhance the taste and quality of foods as well as increase the nutrients and improve the resistance against the pests and herbicides.In some cases, it improve the yield of crops and require only less water or energy for processing. The Genetically Modified foods are especially famous in US when compare to other countries. They expanded their research in almost every area of food production which includes animals, crops and dairy products.In future, the genetically modified foods will be produced with the aim of altering the nutrient content of food, reducing the allergic potential and improve the efficiency of food production systems.
