 Selenium in Nutrition,: Revised Edition by Subcommittee on Selenium Publisher: National Academies Press; 2 edition (January 1, 1983) | ISBN: 0309033756 | Pages: 174 | PDF | 5.33 MB Early interest in selenium by nutritionists concerned its high concentration in certain range plants and the consequent toxicosis in animals that grazed those plants. More recently, the essential nature of selenium has become the center of attention, and this element is now known to be required by laboratory animals, food animals (including fish), and humans. Its role as an integral feature of glutathione peroxidase has been established, and other possible functions are under active investigation. This report reviews current knowledge concerning selenium in nutrition, including chemistry, distribution, metabolism, biochemical functions, deficiency signs, and effects of excess intake. For further background, the reader may wish to refer to the earlier reports of the National Research Council: Selenium in Nutrition (1971), Medical and Biological Effects of Environmental Pollutants: Selenium (1976), and Mineral Tolerance of Domestic Animals (1980).
