The Role of Selenium in Nutrition reviews the most pertinent scientific literature dealing with the basic aspects of the present understanding of the roles of selenium (Se) in nutrition and health. The book begins with a general discussion of Se, covering its various forms, chemistry and physical properties, and techniques for Se analysis. This is followed by separate chapters on the environmental aspects of Se, including its presence in mineral deposits, soils, water, air, and uptake by plants; Se contents of human foods and animal feedstuffs; biological utilization of dietary Se; and absorption, excretion, metabolism, and tissue concentrations of Se. Subsequent chapters deal with the biochemical functions of Se; Se-related diseases of animals and livestock; the role of Se in human health and in support of normal immune function and disease resistance; and the relationship of Se and cancer. The final chapter reviews the evidence concerning the toxicity of Se compounds and sets this in perspective with current knowledge of the roles of Se in nutrition and health, and of the normal exposures of animals and humans to Se compounds.

The goal of this book is to provide up to date information about the roles of Se in poultry nutrition and health. A special emphasis is given to the role of selenium as an essential part of the integrated antioxidant system. Se in feed and organic Se are characterised in detail with emphasis to selenomethionine as a storage form of Se in the body. Also specific Se-deficiency related diseases in poultry are described and the importance of Se in growth, development, immunity and reproduction is demonstrated. A link between poultry industry and human health via production of Se-eggs and Se-enriched meat is shown.

This book provides information about selenium as an important part of integrated antioxidant systems in animal and human bodies responsible for maintaining health. It contains practical advice in relation to effective usage of selenium supplements, including optimal forms and doses. It also combines fundamental information on selenium biochemistry and metabolism. It also presents the most recent findings, unresolved puzzles and future directions for selenium research. In recent years, natural antioxidants have received tremendous attention in relation to human health and food quality. However, the scientific background of many health-promoting claims for natural antioxidants is not always understandable for the general public and needs further clarification. Furthermore, agricultural applications of antioxidants await further investigation.

This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.

Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in humans and farm animals through its incorporation into a range of selenoproteins. Low Se content in main feed ingredients is a common problem worldwide and dietary Se supplementation is a current practice in ruminant nutrition. Recent research clearly proved that sodium selenite, used for the last 50 years as a feed supplement, is not an optimal form of Se. However, use of organic selenium in dairy and beef diets can help meet Se requirement and maintain health/high immunocompetence, productive and reproductive performance. The goal of this book is to provide up-to-date information about the roles of Se in ruminant nutrition and health. A special emphasis is given to the role of selenium as an essential part of the integrated antioxidant system. The concept of using organic Se in ruminant nutrition is described in detail with emphasis on selenomethionine as a storage form of Se in the body. Also, specific Se deficiency-related disorders in ruminants are described and the importance of Se in growth, development, immunity and reproduction is demonstrated. Molecular mechanisms of protective effects of Se under stressful conditions of commercial milk and meat production are characterized. This book will be of practical importance to dairy and beef producers, to nutritionists and vets as well as for animal scientists, students of agricultural colleges and universities. It will also be of interest for researchers in areas related to environmental sciences, food sciences, physiology, etc.

The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

Abstract: A comprehensive, authoritative report of a National Research Council subcommittee reviews current knowledge concerning selenium (Se) in nutrition for nutrition, food, and health professionals. The report focuses on: the chemistry of Se and its analysis; Se distribution in soils, plants, animal feeds, human foods, and water; the Se cycle in nature; biochemical functions of Se (e.g., associations with glutathione peroxidase; nutritional and metabolic inter-associations); Se dietary forms and its absorption, transport, retention, distribution, and metabolism; Se nutritional aspects (dietary requirements and deficiencies in animals, and role in human nutrition); the toxic effects of excess Se; and the effects of high and low Se exposures in human health. A summary of the findings of this report and an extensive list of literature references cited are appended. (wz).
