This book summarizes recent advances in the chemistry, bioactivity, nutrition, and functional aspects of dietary phytochemicals, as well as the health and functional aspects of foods rich in phytochemicals. Consisting of forty-four chapters, it discusses the different chemical types of phytochemicals in our diets and food and presents data collected from animal or human experiments that are directly related to human health. Each chapter covers the chemistry, epidemiological study, bioavailability, bioactivity (animal experiments) function in humans and safety, as well as products on the market. Moreover, the more than 200 figures make it easy to grasp the main findings in each area.

Prof. Dr. D.H.C. Yoshinori Asakawa first studied biology at the Tokushima University, then went to graduate school at Hiroshima University in 1964 and studied organic chemistry, and obtained his PhD degree there and was appointed as a research assistant. Then, Prof. Asakawa went to the Université Louis Pasteur, France, as a postdoctoral fellow, where he worked for 2 years (1972-1974) with Prof. Guy Ourisson, one of the most original natural product chemists worldwide. In 1976 he moved to Tokushima Bunri University as an associate professor, and was promoted to full professor in 1981. Prof. Asakawa served as dean twice, and since 1986, he is director of the Institute of Pharmacology. Prof. Asakawa is the former editor of Phytomedicine and Spectroscopy, and serves on the editorial boards of the Journal of Natural Products, Phytochemistry, Phytochemistry Letters, Planta Medica, Current Chemistry and Biology, Fitoterapia, Flavour and Fragrance Journal, Natural Product Research, Natural Product Communications, Arkivoc and Malaysian Journal of Sciences, among others. He is the president of the Phytochemical Society of Asia (PSA) and of Chemistry of Terpenes, Essential Oils, and Aromatics (TEAC) and permanent committee member of ISEO. His research interests are the isolation and structure elucidation of bioactive secondary metabolites of bryophytes, pteridophytes, and inedible mushrooms; medicinal and aromatic plants and insects and their bioassay; biotransformation of secondary metabolites by fungi and mammals; total synthesis of natural products; chemical reaction of organic per-acids; and chemical phylogeny of spore-forming plants. Prof. Asakawa has published, up to now, 700 original papers, 14 reviews, About the Editors xiii and 40 books. His three books on the "chemical constituents in bryophytes," appeared in "Progress in the Chemistry of Organic Natural Products Vol. 42 (1982), 65 (1995) and 95 (2013)" (Springer Verlag), are the "bibles" for bryophyte researchers, biochemists, phytochemists, and others. For his outstanding research, he was awarded the Hedwig Medal by the International Association of Bryologists; the International Prize of Phytochemistry; Jack Cannon Gold Medal; International Symposium of Essential Oils Award; Gusi International Peace Prize; Gerald Blunden Award; Japanese Society of Pharmacognosy Prize; Gold Medal and Doctor Honoris Causa from Lublin Medical University, Poland; Polish Ambassador of Pharmacy and Fellow of The National Society of Ethnopharmacology, India; and the honorary membership of Turkish Academy of Science. Since 1978, he was invited as the opening, plenary and invited lecturers from 52 countries and he invited 57 post docs and 30 students from various countries into his laboratory and organized International symposia for 8 times in his University as the chairperson.
