Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.
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.
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.
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.

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.
This book reviews the research pertaining to nutrient requirements for working in cold or in high-altitude environments and states recommendations regarding the application of this information to military operational rations. It addresses whether, aside from increased energy demands, cold or high-altitude environments elicit an increased demand or requirement for specific nutrients, and whether performance in cold or high-altitude environments can be enhanced by the provision of increased amounts of specific nutrients.
Vitamins are a group of physiologically very important, chemically quite complex organic compounds, that are essential for humans and animals. Some vitamins and other growth factors behave as antioxidants, while some can be considered as biopigments. As their chemical synthesis is laborious, their biotechnology-based synthesis and production via microbial fermentation has gained substantial interest within the last decades. Recent progress in microbial genetics and in metabolic engineering and implementation of innovative bioprocess technology has led to a biotechnology-based industrial production of many vitamins and related compounds. Divided into three sections, this volume covers: 1. water-soluble vitamins 2. fat-soluble vitamin compounds and 3. other growth factors, biopigments, and antioxidants. They are all reviewed systematically: from natural occurrence and assays, via biosynthesis, strain development, to industrially-employed biotechnological syntheses and applications.
This self-contained book provides modern and practical analytical methodologies for the assays in foods, pharmaceuticals and clinical samples. It covers the fat-soluble Vitamins: A, beta-carotene, D, E and K as well as the water soluble vitamins, C, folate, thiamin, biotin, pyridoxin and cyancobalims.
