This book was released on 2002-07-19 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Download or read book The Fat Soluble Vitamins written by H. DeLuca and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first demonstration of the existence of a vitamin and the full recognition of this fact are often attributed to the work of McCollum, who found that a sub stance in butterfat and cod-liver oil was necessary for growth and health of ani mals fed purified diets. It became obvious that an organic substance present in microconcentrations was vital to growth and reproduction of animals. Following the coining of the word vitamine by Funk, McCollum named this fat-soluble sub stance vitamin A. We can, therefore, state that vitamin A was certainly one of the first known vitamins, yet its function and the function of the other fat-soluble vitamins had remained largely unknown until recent years. However, there has been an explosion of investigation and new information in this field, which had remained quiescent for at least two or three decades. It is now obvious that the fat-soluble vitamins function quite differently from their water-soluble counter parts. We have learned that vitamin D functions by virtue of its being converted in the kidney to a hormone that functions to regulate calcium and phosphorus metabolism. This new endocrine system is in the process of being elucidated in detail, and in addition, the medical use of these hormonal forms of vitamin D in the treatment of a variety of metabolic bone diseases has excited the medical com munity.

Download or read book Bioavailability and Analysis of Vitamins in Foods written by G. F. M. Ball and published by Springer. This book was released on 2013-11-11 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every country in the world is concerned with the nutritional status of its population and in utilizing its natural food resources in the most effective way possible. Surveys based on food intakes and food compositional data are being conducted with the object of establishing recommended intakes of vitamins. These recommendations are constantly being changed as new knowledge comes to light. Analytical techniques using physicochemical and microbiological methods have been largely developed to determine the total vitamin content of a food commodity or diet using the most rigorous extraction method commensurate with the stability of the vitamin. The extraction procedures frequently involve prolonged heating of suitably prepared food samples at extremes of pH to liberate vitamins from chemically bound forms in the food matrix or to remove a preponderance of fat from fatty foods. For several vitamins the data obtained by these means grossly overestimate the nutritional value of the food because the human digestive system fails to liberate bound vitamin forms for subsequent absorption by the intestine. This statement is borne out by reports of vitamin deficiency in situations where the dietary supply of vitamin is adequate on the basis of conventional analysis. Various research labora tories are directing their effort toward the estimation of bioavailable vitamin, i. e. the proportion of vitamin in the food which is available for utilization by the body. So far, few data have been published and there are many gaps in the knowledge required to interpret experimental results.

Download or read book Methods in Vitamin B 6 Nutrition written by James E. Leklem and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the period 29 June to 2 July 1980, a Workshop was held at Timberline Lodge, Mt. Hood, Oregon, entitled "Vitamin B-6 Analyt ical Methodology and Criteria for Assessing Nutritional Status". The papers which follow are the proceedings of that Workshop and represent the combined works of 36 scientists from across the United States and Canada. In addition to the 19 papers, there were seven short presentations which we consider to be at the very frontiers of analytical methods and status assessment for vitamin B-6. These reports discussed such areas as production of specific antibodies to the various vitamers, the synthesis of deuterated vitamers, comparisons of ultraviolet, fluorescence and elctrochemical deter minations of the vitamers and the identification of polyamine pyridoxal Schiff bases in urine. Those reports are not included in this book solely due to their highly tentative and preliminary findings, not because we considered them of any less importance than the papers presented herein. In fact, these reports may well provide the foundations upon which subsequent workshops are devel oped. The feeling for the need of such a Workshop in part grew out of a previous workshop held at the Letterman Army Institute of Research, San Fra"ncisco, California, 11-12 June 1976.

Download or read book Vitamin E written by Etsuo Niki and published by Royal Society of Chemistry. This book was released on 2019-02-04 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin E was discovered in 1922 by Evans and Bishop as an essential micronutrient for reproduction in rats. The active substance was isolated in 1936 by Evans and was named tocopherol, although the tocopherols and tocotrienols are actually a group of eight isomeric molecules that are characterized by a chromanol ring structure and a side chain. Providing an overview of the state-of-the-art of the chemistry of vitamin E, this book reflects the issues stemming from the complexity of the role and actions in vivo as well as in vitro. It summarizes information on the properties and function of vitamin E, the current understanding of the advantages and limitations of it, and also its application in promotion of health and prevention of diseases. Based on sound, solid scientific evidence, this is a timely addition to the literature as the centennial anniversary of the discovery of this important vitamin approaches.
