Available in PDF, EPUB and Kindle. Book excerpt: Vitamin B is a water-soluble vitamin that plays important roles in cell metabolism and synthesis of red blood cells. Many foods contain B vitamins, including meat, poultry, and fish, among others. Vitamin E is a fat-soluble vitamin with antioxidant properties that can be found in vegetable oils, cereals, meat, poultry, eggs, and fruits. Both vitamins B and E are important for human health. This book provides a comprehensive overview of vitamins B and E. It is organized into three sections on the role of vitamin B on body health and gut flora, vitamin B deficiency and its association with the disease pellagra, and the medicinal significance and complications associated with vitamin E deficiency.
Download or read book Vitamin E in Human Health written by Peter Weber and published by Springer. This book was released on 2019-04-01 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin E is a well described and established fat-soluble essential micronutrient and as such has to be provided to the human body on a regular basis in order to avoid deficiency and maintain a healthy status. This is well established and also reviewed in a number of publications. However, a huge body of evidence has accumulated over the last decade, or so, which provides new insights on the mode of action of vitamin E, and the biological role of the tocopherol isomers, and sheds new light on the role of vitamin E in human health. Both fundamental knowledge gain and new data on the role and challenges of vitamin E as an essential micronutrient, including emerging evidence on clinical benefits, will be addressed to put this essential micronutrient in the appropriate perspective. Given this level of new evidence which has emerged over the recent years, a book on vitamin E will put into perspective the concerns which have been raised on vitamin E and which resulted in a misinformation and confusion of the public regarding the importance of vitamin E for human health. This book will reemphasize that Vitamin E is clearly required for human health and its inadequacy leads to increased risk of a variety of diseases. In addition new data of non-communicable diseases (NCD) dependent on vitamin E status show that a lifetime of low intake increases risks of development, severity and complications of NCDs. This text will put the vitamin E case into an up-to-date, science based, applicable real-life perspective and offer pragmatic solutions for its safe and personalized use beyond the various methodological and statistical controversies. The purpose of this book is also to raise awareness not only in the nutrition and medical community, but also in the public media that there are a number of health conditions where an increased intake of vitamin E can be of potential importance. Further this review should also stimulate funding organizations and agencies to increase their support for vitamin E research in order to facilitate the further exploration of the safe and efficacious use of this essential micronutrient.
Download or read book Dietary Reference Intakes for Vitamin C Vitamin E Selenium and Carotenoids written by Institute of Medicine and published by National Academies Press. This book was released on 2000-08-27 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Nutrition and HIV written by Saurabh Mehta and published by CRC Press. This book was released on 2018-05-15 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world continues to lose more than a million lives each year to the HIV epidemic, and nearly two million individuals were infected with HIV in 2017 alone. The new Sustainable Development Goals, adopted by countries of the United Nations in September 2015, include a commitment to end the AIDS epidemic by 2030. Considerable emphasis on prevention of new infections and treatment of those living with HIV will be needed to make this goal achievable. With nearly 37 million people now living with HIV, it is a communicable disease that behaves like a noncommunicable disease. Nutritional management is integral to comprehensive HIV care and treatment. Improved nutritional status and weight gain can increase recovery and strength of individuals living with HIV/AIDS, improve dietary diversity and caloric intake, and improve quality of life. This book highlights evidence-based research linking nutrition and HIV and identifies research gaps to inform the development of guidelines and policies for the United Nations’ Sustainable Development Goals. A comprehensive approach that includes nutritional interventions is likely to maximize the benefit of antiretroviral therapy in preventing HIV disease progression and other adverse outcomes in HIV-infected men and women. Modification of nutritional status has been shown to enhance the quality of life of those suffering HIV/AIDS, both physically in terms of improved body mass index and immunological markers, and psychologically, by improving symptoms of depression. While the primary focus for those infected should remain on antiretroviral treatment and increasing its availability and coverage, improvement of nutritional status plays a complementary role in the management of HIV infection.
Download or read book Military Strategies for Sustainment of Nutrition and Immune Function in the Field written by Institute of Medicine and published by National Academies Press. This book was released on 1999-05-13 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.
Download or read book Laboratory Tests for the Assessment of Nutritional Status written by Howerde E. Sauberlich and published by Routledge. This book was released on 2018-12-19 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper nutrition is the single most important component of preventative health care. Heart disease, diabetes, and other ailments are all linked to dietary habits. Accurate nutritional assessment can be a matter of life or death. Laboratory Tests for the Assessment of Nutritional Status explores the expanded number of nutrients that can now be evaluated. The author makes a compelling case for the practice and advancement of this critical health care tool. Nutritional assessment identifies undernutrition, overnutrition, specific nutrition deficiencies, and imbalances. Diligent assessment determines the appropriate nutrition intervention and monitors its effects. This book is a total revision of the 1974 version of the same title co -authored by Sauberlich. Since then, remarkable progress has been made on the methodologies applicable to nutrition status assessment and to the expanded number of nutrients that can be evaluated, especially trace elements. The introduction of high-performance liquid chromatography, amperometric detectors, and other technologies has advanced nutritional assessment by leaps and bounds. Today, nutritionists can gauge the value of microminerals, trace elements, and ultratrace elements. Sauberlich's revision updates the reader to the latest and most important trends in nutrition. These laboratory methods for the assessment of nutritional status are vital for identifying individuals as well as populations with nutritional risks.
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 User s Guide to the B Complex Vitamins written by Burt Berkson and published by Turner Publishing Company. This book was released on 2006-01-01 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The B-complex vitamins are a family of nutrients that play multifaceted and essential roles in health and preventing disease. They are needed to make and repair DNA and increase energy levels-both key steps for slowing the aging process. Some B vitamins are needed to make mood-enhancing neurotransmitters, such as serotonin, and can have powerful antidepressant benefits. The B vitamin folic acid reduces blood levels of homocysteine, a known risk factor for heart disease, stroke, cancer, and Alzheimer's disease. Vitamin B12 is needed for normal mental function, and low levels can mimic senility. This book explores the remarkable benefits of these and the rest of the B-complex family of vitamins.

Download or read book Dietary Reference Intakes for Thiamin Riboflavin Niacin Vitamin B6 Folate Vitamin B12 Pantothenic Acid Biotin and Choline written by Institute of Medicine and published by National Academies Press. This book was released on 2000-07-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1941, Recommended Dietary Allowances (RDAs) has been recognized as the most authoritative source of information on nutrient levels for healthy people. Since publication of the 10th edition in 1989, there has been rising awareness of the impact of nutrition on chronic disease. In light of new research findings and a growing public focus on nutrition and health, the expert panel responsible for formulation RDAs reviewed and expanded its approachâ€"the result: Dietary Reference Intakes. This new series of references greatly extends the scope and application of previous nutrient guidelines. For each nutrient the book presents what is known about how the nutrient functions in the human body, what the best method is to determine its requirements, which factors (caffeine or exercise, for example) may affect how it works, and how the nutrient may be related to chronic disease. This volume of the series presents information about thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline. Based on analysis of nutrient metabolism in humans and data on intakes in the U.S. population, the committee recommends intakes for each age groupâ€"from the first days of life through childhood, sexual maturity, midlife, and the later years. Recommendations for pregnancy and lactation also are made, and the book identifies when intake of a nutrient may be too much. Representing a new paradigm for the nutrition community, Dietary Reference Intakes encompasses: Estimated Average Requirements (EARs). These are used to set Recommended Dietary Allowances. Recommended Dietary Allowances (RDAs). Intakes that meet the RDA are likely to meet the nutrient requirement of nearly all individuals in a life-stage and gender group. Adequate Intakes (AIs). These are used instead of RDAs when an EAR cannot be calculated. Both the RDA and the AI may be used as goals for individual intake. Tolerable Upper Intake Levels (ULs). Intakes below the UL are unlikely to pose risks of adverse health effects in healthy people. This new framework encompasses both essential nutrients and other food components thought to pay a role in health, such as dietary fiber. It incorporates functional endpoints and examines the relationship between dose and response in determining adequacy and the hazards of excess intake for each nutrient.

Available in PDF, EPUB and Kindle. Book excerpt: Vitamin E is a group of fat-soluble compounds found in a wide variety of foods. Daily requirements of vitamin E can be met with a balanced diet. High-dose supplementation may be hazardous rather than beneficial. Vitamin E serves as an antioxidant, participates in anti-inflammatory processes, inhibits platelet aggregation, and enhances immunity. Vitamin E supplementation can be beneficial against coronary artery disease, eye disorders, cognitive decline, cancer, and skin aging. This book will mainly focus on the diverse functions of vitamin E, importance of vitamin E status to provide a healthy lifespan, and the interaction between vitamin E and several pathological conditions. Readers will receive a general overview of the importance of vitamin E in health and different pathological conditions.
Download or read book Methods for the Determination of Vitamins in Food written by D. Brubacher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the course of the project COST 91 *, on the Effects of Thermal Processing and Distribution on the Quality and Nutritive Value of Food, it became clear that approved methods were needed for vitamin determination in food. An expert group on vitamins met in March 1981 to set the requirements which these methods must meet. On the basis of these requirements, methods were selected for vitamin A, ~-carotene, vitamin B1 (thiamine), vitamin C and vitamin E. Unfortunately, for vitamins B2 (riboflavin), B6 and D only tentative methods could be chosen, since the methods available only partially fulfilled the require ments set by the expert group. For niacin and folic acid some references only could be given because none of the existing methods satisfied these requirements, and for vitamin B , vitamin K, pantothenic acid and 12 biotin it was not considered possible to give even references. All methods were carefully described in detail so that every laboratory worker could use them without being an expert in vitamin assay. In October 1983 an enlarged expert group on vitamins approved the compilation of methods and approached a publishing house with a view to publication. The editors wish to thank Dr Peter Zeuthen, the leader of the project COST 91, for his interest in their work, and Mr G.
Download or read book Water Soluble Vitamins written by Olaf Stanger and published by Springer Science & Business Media. This book was released on 2011-11-27 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
