Genetically modified foods are those that have had specific changes introduced into their DNA by genetic engineering techniques. They are modified for a faster growth, resistance to patogens, production of extra nutrients or any other beneficial purpose.
Some of the advantages they have are for example, the reduced maduration time, the new products that are appearing, the fact that they improve animals health and that they take a more efficient processing.
But it also has some disadvantages like potencial human health impacts (as enviromental impacts) or stress to animals.
So, in my opinion, GM food is a great advance that will help lots of populations all over the world to develop, as long as they use this advance in a safe way.
