ABSTRACT
Consideration of the foregoing chapters demonstrates that the pace of development of research addressing phytochemicals and their potential for improving human health and well-being is increasing. In the face of such rapid change, the wisdom of highlighting key areas for future research may be questioned; first, because it is to be expected that major advances in some areas will be achieved within an unexpectedly short time, and second, because the significance of others will become more obvious with hindsight. In addition, serendipity will continue to provide unexpected opportunities, and each new advance will present the research community with additional challenges.
