Book Description

Protein and Amino Acid Nutrition describes the state of knowledge concerning the nutrition of proteins and amino acids. Topics range from the effect of some therapeutic agents on protein and amino acid nutrition, to species and age differences in amino acid requirements; utilization of D-amino acids; effect of proteins and amino acids on the growth of adult tissue in vitro; and amino acid requirements of animals and young adults. This volume is organized into 16 chapters and begins with an overview of the nutritional implications of the metabolic interrelationships of amino acids. The next chapters discuss experiments that tested the differences in amino acid requirements due to the differences in age and in species among animals, the biochemical individuality of amino acid requirements, and the utilization of dietary proteins. This book explains the synthesis of tissue proteins in relation to the essential amino acids; the link between food energy and nitrogen metabolism; and the use of the repletion method to measure the nutritive value of proteins, protein hydrolyzates, and amino acid mixtures. The final chapter discusses the nutritional needs of the older age groups. This book is intended for scientists, students, and researchers interested in human and animal nutrition.

Book Description

It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

Book Description

Amino acids (AAs) are not only building blocks of protein, but are also signalling molecules as well as regulators of gene expression and the protein phosphorylation cascade. Additionally, AAs are key precursors for syntheses of hormones and low-molecular weight nitrogenous substances with each having enormous biological importance. For example, physiological concentrations of AA metabolites (e.g., nitric oxide, polyamines, glutathione, taurine, thyroid hormones, and serotonin) are required for cell functions. Growing evidence shows that humans and animals have dietary requirements for all proteinogenic AAs. Mammals, birds and fish also have species- and age-dependent needs for some AA-related substances. However, elevated levels of other products (e.g., ammonia, homocysteine, H2S, and asymmetric dimethylarginine) are pathogenic factors for neurological disorders, oxidative stress, and cardiovascular disease. Thus, optimal amounts of AAs and their ratios in diets and circulation are crucial for whole body homeostasis and health. Adequate provision of one or a mixture of functional AAs or metabolites may be beneficial for ameliorating health problems at various stages of the life cycle (e.g., fetal growth restriction, neonatal morbidity and mortality, weaning-associated intestinal dysfunction and wasting syndrome, obesity, diabetes, cardiovascular disease, the metabolic syndrome, and infertility). Dietary supplementation of these nutrients can also optimize the efficiency of metabolic transformations to enhance muscle growth, milk production, and athletic performance, while preventing excess fat deposition and reducing adiposity. Therefore, functional AAs hold great promise in improving the growth, health and well-being of individuals.

Book Description

This edited volume comprehensively highlights recent advances in the metabolism, nutrition, physiology, and pathobiology of amino acids in all the systems of humans and other animals (including livestock, poultry, companion animals, and fish). It enables readers to understand the crucial roles of amino acids and their metabolites in the health and diseases of the circulatory, digestive, endocrine, immune, muscular, nervous, reproductive, respiratory, skeletal, and urinary systems, as well as the sense organs (eyes, ears, nose, skin, and tongue). Readers will learn that amino acids are not only the building blocks of protein, but are also signalling molecules, as well as regulators of gene expression, metabolic processes and developmental changes in the body. This knowledge will guide nutritional practices to improve the growth, development and health of humans and other animals, as well as prevent and treat chronic (e.g., obesity, diabetes, and cardiovascular disorders) and infectious (e.g., bacterial, fungal, parasite, and viral) diseases. Editor of this volume is an internationally recognized expert in nutritional biochemistry. He has over 38 years of experience with research and teaching at world-class universities in the area of amino acid biochemistry, nutrition, and physiology.

Book Description

Since its introduction in 1943 Recommended Dietary Allowances has become the accepted source of nutrient allowances for healthy people. These Recommended Dietary Allowances (RDAs) are used throughout the food and health fields. Additionally, RDAs serve as the basis for the U.S. Recommended Daily Allowances, the Food and Drug Administration's standards for nutrition labeling of foods. The 10th Edition includes research results and expert interpretations from years of progress in nutrition research since the previous edition and provides not only RDAs but also "Estimated Safe and Adequate Daily Dietary Intakes"â€"provisional values for nutrients where data were insufficient to set an RDA. Organized by nutrient for ready reference, the volume reviews the function of each nutrient in the human body, sources of supply, effects of deficiencies and excessive intakes, relevant study results, and more. The volume concludes with the invaluable "Summary Table of Recommended Dietary Allowances," a convenient and practical summary of the recommendations.
