Energy and Protein Metabolism and Nutrition


Book Description

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.




The Role of Protein and Amino Acids in Sustaining and Enhancing Performance


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.







Seafood Proteins


Book Description

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.




Milk Proteins


Book Description

This book reviews the state of knowledge and progress of research on food proteins, and in particular, milk proteins. Its basis is the Symposium on Milk Proteins that was held at the Federal Dairy Research Centre in Kiel, FRG, in June, 1988. Scien tists from around the world attended and addressed pure, as well as applied fields of protein research and technology. This book is divided into five sections, each adapted from the symposium's invited lectures, short communications, and poster presentations. New criteria for the "bio logical value" of dietary proteins and their relationships are considered according to: - Milk Proteins and Nitrogen Equilibrium - Milk Proteins and Ligands - Milk Proteins: Structural and Genetic Aspects - Milk Proteins: Technological and Functional Aspects - Milk Proteins and Clinical Nutrition Generally, different dietary proteins are classified according to their "biological value," i.e., their capacity to cause different retention of nitrogen in the body. But we think there are other intriguing leads worth studying that may help to identify which dietary proteins are best recommended for specific dietary situations or clini cal conditions. In addition, we have taken into consideration new fields such as attempts to determine the three-dimensional structure of proteins using two-dimensional NMR spectroscopy, and the application of genetic engineering to the lactating cell. In other words, we are on the way to the transgenic cow with customized milk constituents and composition.




Amino Acid Composition and Biological Value of Cereal Proteins


Book Description

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.
