Available in PDF, EPUB and Kindle. Book excerpt: Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.

Download or read book Nutritional Improvement of Food and Feed Proteins written by Mendel Friedman and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 879 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nutritional quality of a protein depends on the proportion of its amino acids-especially the essential amino acids-their physio logical availability, and the specific requirements of the consumer. Availability varies and depends on protein source, interaction with other dietary components, and the consumer's age and physiological state. In many foods, especially those from plants, low levels of various essential amino acids limits their nutritive value. This is particularly important for cereals (which may be inadequate in the essential amino acids isoleucine, lysine, threonine, and tryto phan) and legumes (which are often poor sources of methionine). Moreover, these commodities are principle sources of protein for much of the earth's rapidly growing population. At the current annual growth rate of about 2 percent, the world population of about 4 billion will increase to 6.5 billion by the year 2000 and to 17 billion by the year 2050. Five hundred milliQn people are presently estimated to suffer protein malnutrition, with about fifteen thousand daily deaths. The ratio of malnourished to adequately nourished will almost surely increase. For these reasons, and especially in view of the limited availability of high quality (largely animal) protein to feed present and future populations, improvement of food and feed quality is especially important.

Download or read book The Role of Protein and Amino Acids in Sustaining and Enhancing Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1999-09-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Protein and Amino acid nutrition written by Anthony Albanese and published by Elsevier. This book was released on 2012-12-02 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Dietary Protein Research Trends written by Janet R. Ling and published by Nova Publishers. This book was released on 2007 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proteins are made of strings of amino acids that form chains known as peptides. Our bodies need dietary protein to accomplish many basic functions, such as building bones, moving muscles, and repairing tissue. Dietary protein, an essential nutrient, comes from meat, dairy, and certain grains and beans. Proteins differ by the types and order of amino acids they contain. Even though there are only 20 amino acids, they create almost endless variations in chains as long as 500 links. Proteins form inside animals (including humans) and plants through processes that synthesize peptides. For humans, we cannot synthesise certain "essential protein," and so we must ingest them through food. These essential proteins are made of phenylalanine, threonine, methionine, tryptophan, leucine, isoleucine, lysine, and valine amino acids. Food from plants, like corn, have incomplete protein, which means they do not contain all the necessary amino acids. Only food from animals, such as cheese and fish, provide complete protein, and don't need to be combined with other protein sources. Examples of complete protein foods are milk, cheese, yogurt, butter, poultry, pork, or any meat. Incomplete proteins include oats, wheat, pasta, lentils, nuts, rice, soy, pears, and seeds. Eating a combination of complementary protein sources, such as grains mixed with legumes, results in a diet of essential protein. This is how vegetarians and vegans maintain health without eating meat or dairy. This book presents the latest research in this dynamic field.

Download or read book Modern Methods in Protein Nutrition and Metabolism written by Steven Nissen and published by Academic Press. This book was released on 2012-12-02 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods in Protein Nutrition and Metabolism grew out of a series of seminars (Modern Views in Nutrition) held in 1989 at Iowa State University. These seminars and this book were financed primarily through the Wise and Helen Burroughs Lectureship endowment generously established by the late Dr. Wise Burroughs and his wife Helen. This book comprises 12 chapters, and begins with a focus on amino acid analysis in food and physiological samples. Succeeding chapters go on to discuss concepts and techniques on nitrogen balance; determination of the amino acid requirements of animals; and novel methods for determining protein and amino acid digestibilities in feedstuffs. Other chapters cover measurement of protein digestion in ruminants; evaluation of protein status in humans; surgical models to measure organ amino acid metabolism in vivo; and measurement of whole-body protein content in vivo. The remaining chapters discuss estimation of protein synthesis and proteolysis in vitro; isotopic estimation of protein synthesis and proteolysis in vivo; n-glycine as a tracer to study protein metabolism in vivo; and mathematical models of protein metabolism. This book will be of interest to practitioners in the fields of human nutrition and medicine.
