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 Seafood Proteins written by Z. Sikorski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish and marine invertebrates are important sources of nutrients for the world's population, and many species have exceptionally high market value because of their exquisite sensory properties. Both the utilization of the available catch in different forms and the market price are affected by the quality of the fish. Proteins and nonprotein nitroge nous compounds playa crucial role in the nutritional value and sensory quality of seafoods as well as in the suitability of different species to various forms of processing, preservation, and use in other branches of the food industry. This role of proteins results from their basic chemical and biochemical properties and functions in different tissues. A presenta tion of the actual state of knowledge on seafood nitrogenous compounds in one volume may contribute to a better understanding of the involve ment of these components in all stages of handling and processing fish. It has been possible to prepare this text thanks to the cooperative effort of an international group of specialists. The editors of the book are greatly indebted to all colleagues who have willingly contributed to this volume, sharing their knowledge and experience, as well as to all persons who have granted permission to use their previously published materials. viii Preface ix A large part of the book has been prepared during my sabbatical in the Department of Marine Food Science, National Taiwan Ocean University (NTOU) in Keelung, Taiwan.

Book Synopsis Amino Acid Composition and Biological Value of Cereal Proteins by : Radomir Lásztity
Download or read book Amino Acid Composition and Biological Value of Cereal Proteins written by Radomir Lásztity and published by Springer Science & Business Media. This book was released on 1985-07-31 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cereals belong to the most important elements in the history of mankind. From the beginning of agriculture, cereals have been by far the most important staple food in the world. Although the cereal consumption decreased to a low level in the developed countries in Europe and North America, in the devel oping countries over two-thirds of the calorie and protein intake is based on cereals. A substantial quantity of cereals goes indirectly into food via feed to animals. Generally, cereal proteins are classified as proteins of lower biological value because of shortage in lysine and some other essential amino acids. Recent developments in the de termination and evaluation of the biological value of proteins and protein mixtures suggest that the oversimplified earlier evaluation of cereal proteins must be reviewed. This book contains the edited proceedings of the Inter national Symposium on "Amino Acid Composition and Biological Value of Cereal Proteins", held in Budapest, Hungary, Hay 31- June 1, 1983, under the sponsorship of the International Association for Cereal Chemistry, Hungarian Scientific Society for Food Industry and Grain Trust, Hungary, with supplemental invited contributions. Scientists (biologist, plant breeders, farmers, chemists, biochemists, engineers, food technologists and nutritionists) from 17 countries presented and reviewed, along with partici pants from 20 countries, the recent methodology and trends in the determination of the biological value of cereal proteins, v the amino acid composition of cereal proteins and factors in fluencing the composition and the role of cereal proteins in nutrition and animal feeding.

Book Synopsis Protein quality assessment in follow-up formula for young children and ready to use therapeutic foods by : Food and Agriculture Organization of the United Nations
Download or read book Protein quality assessment in follow-up formula for young children and ready to use therapeutic foods written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-21 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consistent with the need to provide safe food for young children, particularly during the complementary feeding period between 12 and 36 months and the period of rapid development to age 59 months, the Food and Agriculture Organization of the United Nations (FAO) convened an Expert Working Group the FAO Headquarters, Rome, Italy, from 6 to 9 November 2017. The meeting addressed questions related to protein quality evaluation in two distinct products used to feed children in different conditions: Ready to Use Therapeutic Food (RUTF) and Follow up Formula for Young Children (FUF-YC). Specific meeting objectives were: •To determine the appropriate comparative protein or amino acid reference pattern to define protein quality for use in FUF-YC and RUTF. •To provide guidance on the preferred protein quality assessment methodology that should be stipulated with the standards for FUF-YC and RUTF. •To provide guidance on the measurement of protein and amino acid digestibility. •To provide the appropriate reference amino acid profiles and the amino acid composition of common ingredients used for FUF-YC and RUTF. •To provide cost implications for countries to use PDCAAS in FUF-YC and RUTF. This report provides future research recommendations including the need to generate data on the true ileal digestibility for different protein sources so that Digestible Indispensable Amino Acid Score (DIAAS) values can be used in the future.

Book Synopsis Development of a protein database and the way forward for reviewing protein requirements by : Food and Agriculture Organization of the United Nations
Download or read book Development of a protein database and the way forward for reviewing protein requirements written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org. [Author] [Author]. This book was released on 2024-06-25 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing an adequate, sustainable, and nutritious supply of protein remains an increasing challenge in the light of changing food systems and raised levels of food insecurity and malnutrition. A joint FAO and IAEA technical meeting was held in Vienna, in 2022, to discuss the development of a protein quality database and the revision of protein requirements across population groups. Participants updated evidence and related methods on protein requirements and protein quality assessment and designed a framework for the development of a protein digestibility database to aid dialogue on the evaluation of protein quality and protein sufficiency in different populations. The report of this meeting offers a global presentation of the concept of protein quality and requirements throughout the life course. It presents the important elements needed to set protein requirements, such as indispensable amino acid scores and indispensable amino acid reference patterns and the associated methods. The report then narrows down on assessment of protein digestion and metabolic utilization and related assessment methods, including stable isotope tracer techniques. Finally, the report summarizes the framework for a new protein quality database jointly managed by FAO and IAEA, which was agreed on by experts at the technical meeting. The report also recognizes the dearth of data on protein quality from low- and middle-income countries and recommends that resources be mobilized to set up a protein quality database, inclusive of data on climate-smart foods.
Book Synopsis Evaluation of Dietary Protein Quality by : Alejandro Uribe-Peralta
Download or read book Evaluation of Dietary Protein Quality written by Alejandro Uribe-Peralta and published by . This book was released on 1978 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The use of a target protein against which the quality of other dietary proteins could be compared has been examined in rats. Milk, the natural food during the early life of mammals, was proposed as the target standard. The milk standard diet was compared with proteins of different origins, amino acid pattern, or lacking an essential amino acid. A chemical score based on rat's milk (CSM-R) was developed to evaluate the quality of the protein diets; it combined determination of a protein's most limiting amino acid with a capacity for ranking proteins by nutritional values. Diets were evaluated for protein efficiency ration, body weight gain, levels of amino acids and protein complementation. Results indicated that rat milk contains a proportion of amino acids which provides maximum protein utilization in growing rats, and may also protect the lactating mother. Other diets were usually inferior. The CSM-R score appeared to be a useful analytic tool in evaluating the quality of dietary proteins.
Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.

Book Synopsis Biological Sequence Analysis by : Richard Durbin
Download or read book Biological Sequence Analysis written by Richard Durbin and published by Cambridge University Press. This book was released on 1998-04-23 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Probabilistic models are becoming increasingly important in analysing the huge amount of data being produced by large-scale DNA-sequencing efforts such as the Human Genome Project. For example, hidden Markov models are used for analysing biological sequences, linguistic-grammar-based probabilistic models for identifying RNA secondary structure, and probabilistic evolutionary models for inferring phylogenies of sequences from different organisms. This book gives a unified, up-to-date and self-contained account, with a Bayesian slant, of such methods, and more generally to probabilistic methods of sequence analysis. Written by an interdisciplinary team of authors, it aims to be accessible to molecular biologists, computer scientists, and mathematicians with no formal knowledge of the other fields, and at the same time present the state-of-the-art in this new and highly important field.
