Current and future benefits from the use of GM technology in food production.

For the current generation of genetically modified (GM) crops the improvement of agronomic traits (e.g. herbicide tolerance, insect resistance) has been a major objective. The lack of obvious and direct benefits for the consumer has been a main point of criticism. Future trends will increasingly encompass the modification of quality traits, such as the improvement of sensory and especially nutritional properties. Some of the ongoing developments try to meet the desire of consumers for ‘healthy’ or ‘high-tech’ foods in developed countries. Others are intended to assist in adjusting the nutritional status of foods to the needs of consumers in developing countries. Considering the increasing world population and the limited amount of arable land, GM technology may also become a valuable tool to ensure food security. The major prerequisite for the applicability of the technique is the safety of the resulting products. The increasing complexity of modifications intended might require adjustments and improvements of the strategies applied to the safety assessment of GM foods. Present research activities try to meet these new challenges.
