In the past five years, a surprising and intense resurgence in interest in vitamins and other micronutrients and their role in health and dis ease has occurred. The recognition has emerged that vitamins not only are essential for life ·in that severe nutritional deficiencies occur in their absence, but that these compounds may also serve as natural inhibitors of cancer. Synthetic alterations of the basic vitamin A mole cule have also resulted in the production of compounds that are more potent as anticancer agents than the natural substance and may have substantial therapeutic activity as well. Whether other vita mins can be changed or altered to produce a better anticancer effect than the native compound has been little explored to date, but should be a fruitful pursuit for future study. In our concluding remarks to the First International Conference in 1982, we speculated that rapid advances in our understanding of vi tamins would occur in the next few years and that large-scale inter vention trials of vitamins as preventive agents in defined human pop ulations would be started. This anticipated generation of data on vitamins and their interactions has proceeded rapidly and the impor tance of interactions between vitamins and other micronutrients in the prevention setting has become better appreciated. Currently, more than 25 intervention trials with a variety of target populations using vitamins and other micronutrients have been started, but it re mains too early for meaningful analysis of the results to date.

The discovery of vitamins in the early 1900s, their later chemical characterization and the clarification of pivotal metabolic functions are sequential aspects of a brilliant chapter in the history of modern nutritional sciences and medicine. The name, derived from “vital-amines”, indicates their elementary metabolic key functions in human metabolism. Vitamins are truly families of compounds, which include precursors and various free and bound forms, all with individual roles in metabolism and function. A more recent approach therefore searches for the components, the understanding of their roles in physiology and pathology as well as looking for novel pharmacological applications. When used properly, vitamins are, indeed, “magical” substances. Due to their efficacy, they should therefore be regarded as drugs with effects and side effects to be weighted against each other. Today, it is not the previously fatal deficiency-associated diseases that are in the focus of interest, but rather the relation of suboptimal vitamin bioavailability to chronic disease. This is complicated by genetic susceptibility, lifestyle, and the presence or absence of health-compromising habits, such as smoking. In turn, the development and application of new and more sensitive and specific assays further enable us to look more closely into the many functions of vitamins. Water soluble vitamins are complex molecular structures and even today, many areas in vitamin biochemistry are not yet fully understood. Novel effects and functions of vitamins remain and continue to be discovered. This book presents most recent research results and fascinating new knowledge on the role and effects of the water soluble vitamins in man. Some of the most distinguished chemists, biochemists, biologists and clinicians have contributed valuable chapters sharing unexpected novel insights into the biochemistry, (epi)genetics, metabolism, and function of water soluble vitamins, with their potential for clinical applications. Thus, physicians, clinicians, scientists, researchers, epidemiologists. nutritional specialists and health professionals alike will find stimulating and fascinating new insight in the many roles that water soluble vitamins play in human health and disease.

The concept of “vital amines” as essential nutrients was introduced over a century ago by Dr Casimir Funk. It was suggested that there is a family of organic substances that are required in minute amounts and essential for life. The increase in incorporation of vitamins and supplementation in routine dietary practices is expected to increase. In fact, it has been estimated that 60% of worldwide consumers are taking vitamin supplements on a daily basis, a trend that will most likely rise across the world. This book brings together international experts in the field of vitamins for human health and disease, to update and integrate current understanding on the effects of different lipophilic vitamins on cellular, metabolic and molecular biochemical reactions with respect to different pathophysiological conditions including cardiovascular disease, cancer, metabolic defects, inflammatory and immune diseases. This book is uniquely positioned as it focuses on the biochemistry and molecular biology of lipophilic vitamins in diverse cell systems in relation to human health and disease. The book will certainly stimulate and motivate biomedical researchers and scientists to further explore the relationship between lipophilic vitamins and biological processes, as well as serve as a highly useful resource for nutritional investigators, health professionals, medical students, fellows, residents and graduate students. We hope that the reader will gain knowledge and further understanding of the importance of lipophilic vitamins. The novel insights provided by the contributing authors will assist in advancing preventive medicine worldwide as well as bring forward knowledge that may help in the use of lipophilic vitamins as adjuvant to therapeutic strategies for human disease.

Free Radicals in Biology and Medicine has become a classic text in the field of free radical and antioxidant research. Now in its fifth edition, the book has been comprehensively rewritten and updated whilst maintaining the clarity of its predecessors. Two new chapters discuss 'in vivo' and 'dietary' antioxidants, the first emphasising the role of peroxiredoxins and integrated defence mechanisms which allow useful roles for ROS, and the second containing new information on the role of fruits, vegetables, and vitamins in health and disease. This new edition also contains expanded coverage of the mechanisms of oxidative damage to lipids, DNA, and proteins (and the repair of such damage), and the roles played by reactive species in signal transduction, cell survival, death, human reproduction, defence mechanisms of animals and plants against pathogens, and other important biological events. The methodologies available to measure reactive species and oxidative damage (and their potential pitfalls) have been fully updated, as have the topics of phagocyte ROS production, NADPH oxidase enzymes, and toxicology. There is a detailed and critical evaluation of the role of free radicals and other reactive species in human diseases, especially cancer, cardiovascular, chronic inflammatory and neurodegenerative diseases. New aspects of ageing are discussed in the context of the free radical theory of ageing. This book is recommended as a comprehensive introduction to the field for students, educators, clinicians, and researchers. It will also be an invaluable companion to all those interested in the role of free radicals in the life and biomedical sciences.

Vitamins - especially B- and D-vitamins - influence the development and outcome of many neurodegenerative and other diseases. Among others, dementia, neural tube defects, epilepsy, and osteoporoses can be caused by vitamin deficiency. This book provides up-to-date knowledge on the role of water and fat soluble vitamins in the prevention of human diseases. Having knowledge about the association of vitamins and disease, as well as keeping track on the patients vitamin status has become increasingly important to every physician and clinical chemist.

More than 100 years ago, Dr Casimir Funk suggested the existence of a family of organic substances that are essential for life and thus introduced the concept of “vital amines” as essential nutrients with a specific action, requiring only minute amount with the power to cure a specific disease. Vitamins essential for human health are grouped according to whether they are soluble in water (hydrophilic) or in non-polar solvents (lipophilic). The hydrophilic vitamins are vitamin C and a series known as the vitamin B complex. Vitamin C is a reducing agent, whereas the vitamin B series are components of coenzymes. For example, riboflavin (vitamin B2) is a precursor of flavin adenine dinucleotide (FAD) and pantothenate (vitamin B5) is a component of coenzyme A. Indeed, several coenzymes contain a vitamin as part of their structure; this relation is undoubtedly responsible for creating an “essential” role for the vitamin. Since vitamins are involved in a wide range of biological processes and cell function, these are considered as essential nutrients. The essential nature of vitamins as well as their unique biochemistry, molecular mechanisms and cellular function in health and disease are emphasized in this book which will serve as a highly useful resource for health professionals, nutritional scientists, medical students, fellows, residents, and graduate students.
