    Genetically modified foods are foods whose genes have been changed, to alter their characteristics. They have not been proved to be dangerous yet neither have they proved to be 100% safe.

    New genes can be added to the plant, for example to make the plant produce more vitamins ( see golden rice --> wikipedia)

    Or genes that are already in the plant could be blocked like the example below.

    An example is the Flavr Savr tomato, the tomato plants were modified to prevent them producing a particular enzyme which makes the tomato go soft upon ripening. The genetically modified tomatoes did not go soft and so it was easier to pick them and therefore a better quality of tomato was shipped to suppliers. These tomatoes were said to tase better than non genetically modified tomatoes, although due to marketing failures the tomatoes are no longer available.

    They mess around with the inside of the food to make it bigger or grow faster or something like that. It's dangerous to eat that kind of food, they already banned it in other countries because it's so dangerous.
