GM food (genetically modified food)

Genetically modified foods (GM foods), also known as genetically engineered foods (GE foods), are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.


GM foods are controversial. Some people have concerns around their long-term safety and also their environmental impact. Advocates of GM foods argue that they are easier and less costly for farmers to grow and that they enhance foods’ nutrients, flavour, and appearance.
