Introduction

Abstract

From among the vast array of phytochemicals, we selected for this American Society for Nutritional Sciences Symposium on Phytochemicals: Biochemistry and Physiology several phytochemical classes that show promise for early application, including the polyphenolics, phytoestrogens, monoterpenes, and isothiocyanates. Reviews of the last-mentioned three classes are presented in this supplement. Our growing understanding of the role of phytochemicals and the development of functional foods hold the potential for a significant effect on the national economy because medical care dollars can be saved through preventive nutrition and the provision of less tangible, but no less important, benefits to our quality of life.
