... When food products are modified by this process, they are known as Genetically Modified foods or GM foods, which are produced and consumed widely all over the world, for instance, soybeans, corns, potatoes, tomatoes and cotton oils (Healey 2000).
The arguments for GM foods are that they may be more productive to suppliers, more nutritious to mankind and more affirmative for environment than naturally grown foods.
First, in the aspect of production, Genetic Modification technology may encourage to produce a large quantity of foods and raise yields in limited farm land space now that it can enhance features of crops against pest (Subramanian 2004). Furthermore, the cost reduction of cultivation and production might have a firsthand effect on mass production, which could consequently have brought about inexpensive foods and mass consumption. For instance, in the USA, Japan, Europe and etc, a large deal of GM foods have been sold at low price such as soybeans, corns, potatoes and tomatoes because they gathered a good harvest are available to build up food markets with much cheaper price.
Second, GM foods which have been promoted in conspicuously high nutritive value can raise the possibility of human health. To put it concretely, Genetic Modification technology is available to enhance nutrient content and also nutrient balance in foods.
