Book Description
Nutrient Delivery: Nanotechnology in the Agri-Food Industry, Volume Five, discusses the fabrication, merits, demerits, applications, and bioavailability enhancement mechanisms of various nanodelivery systems. Recent developments in various nanodelivery systems are also highlighted. Volume 5 contains twenty chapters, prepared by outstanding international researchers from Argentina, Brazil, Canada, China, Croatia, India, Iran, Ireland, México, Pakistan, Portugal, Serbia, Sri Lanka, and the United States. In recent years, the delivery of micronutrients at nanoscale has been widely studied as these systems have the potential to improve bioavailability, enable controlled release and enhance stability of food bioactives to a greater extent. The nanodelivery systems typically consist of the food bioactive compound encapsulated and stabilized in food grade ingredients such as lipids, proteins or polysaccharides with diameters ranging from 10 nm to 1000 nm. Among these, the lipid based delivery systems such as nanoemulsions, solid lipid nanoparticles, nanoliposomes and micelles are widely studied for the delivery of lipophilic bioactive compounds. These delivery vehicles improve the solubility, permeability, stability and bioavailability of the lipophilic compounds thereby enhancing their potential for oral delivery and functional food development. On the other hand, the hydrophilic bioactives are delivered through protein, polysaccharide or biopolymer based colloidal nanosystems such as hydrogels, nanogels and polymer nanoparticles. The major concern other than solubility is the intestinal permeability of the micronutrients. For instance, the delivery system for compounds with poor intestinal permeability and low solubility need to be carefully designed using suitable lipids and surfactants. Offers updated material for undergraduate and postgraduate students in food science, biotechnology, and related engineering fields Provides a valuable resource of recent scientific progress, along with most known applications of nanomaterials in the food industry for researchers, engineers, and academics Includes novel opportunities and ideas for developing or improving technologies in the food industry

Book Description
Active ingredients in foods must remain fully functional for as long as necessary and be transported and discharged appropriately to have the desired nutritional effect. Delivery and controlled release systems are an essential way to achieve these aims. This important book reviews how to optimise these systems to maximise the health-promoting properties of food products. Opening chapters review factors affecting nutrient bioavailability and methods to test delivery system efficacy. Part two addresses materials used and specific techniques for delivery and release. The benefits and drawbacks of structured lipids, micro- and nano-emulsions, food-protein-derived materials, complexes and conjugates of biopolymers, and starch as an encapsulation material for delivery of functional food ingredients, are all considered. Part three discusses the delivery and controlled release of particular nutraceuticals such as antioxidants and vitamins, folic acid, probiotics, fish oils and proteins. Part four covers regulatory issues and future trends in bioactives and nutraceuticals. Edited by a leading expert in the field, Delivery and controlled release of bioactives in foods and nutraceuticals is a valuable reference for those working in the food industry and particularly those developing nutraceuticals. Reviews techniques to optimise the delivery and release of bioactives in food Discusses the factors that affect nutrient bioavailability and methods to test delivery system efficacy Addresses materials used and specific techniques for delivery and release

Book Description
The Role of the Gastrointestinal Tract in Nutrient Delivery contains the proceedings of the third annual Bristol-Myers Symposium on Nutrition Research, held on December 1-2, 1983 in Washington, D.C. Contributors focus on the knowledge and research findings concerning the role of the gastrointestinal tract in nutrient delivery. This text is organized into 15 chapters and addresses topics such as gastrointestinal motility; hormonal regulation of growth and function; the mechanisms of digestion and absorption; and the diverse effects of intestinal contents on nutrient absorption and antigenic response. The discussion begins with an overview of the gastrointestinal tract, with emphasis on factors that affect the growth of gastrointestinal mucosa and the implications for nutrition. This book then turns to kinetic and biochemical parameters related to the development of several diseases of the gastrointestinal tract. The reader is also introduced to the basic aspects of organization of the systems in which peptides act as regulators of digestion; the role of endogenous prostaglandins in the gastrointestinal tract; and gastric secretion. A chapter on the age-related functions of digestive tract organs concludes the book. This book will be of value to physicians and scientists as well as students and researchers who have an interest in the crucial role of the gastrointestinal tract in converting food into the nutrients the body uses to sustain its functions.

Book Description
Sports nutrition has evolved beyond what to eat and how much to eat to now include the question of when to eat. A hot topic in sports nutrition, nutrient timing is a dietary concept that takes into account time as a missing dimension in athletic performance and recovery. Not only is the consumption of nutrients in ideal amounts and proportions important, but the timing with which they are administered is also of prime importance—the right nutrients at the ideal time to affect performance and muscular growth. Nutrient Timing: Metabolic Optimization for Health, Performance, and Recovery presents the most authoritative text to date that scientifically examines the contemporary topic of nutrient timing. Worldwide research continues to rapidly explore the metabolic impact of nutrient timing and how its proper application may help to improve performance. With contributions from scientists and practitioners in the field, this book gathers the latest evidence-based information on this cutting-edge area. The chapters cover macronutrients—carbohydrates, proteins, and lipids—and their role in sporting activity, as well as an examination of vitamins and minerals. The core of the book focuses on pre-exercise, mid-exercise, and post-exercise considerations for both resistance and aerobically mediated activity. Using the models presented, individuals may improve performance, promote optimal adaptations to training, maximize recovery, and facilitate healthy interactions with their environment. The final chapters of the book describe future concepts in nutrient timing, including the impact of protein source in the context of timing, how nutrient timing can fit in with a comprehensive recovery program, and the application of the ideas discussed in unique populations such as the aged, the military, and populations interested in weight loss. This text provides solid data from the scientists themselves, giving researchers, teachers, coaches, and medical and health care professionals the necessary information they need to accurately and effectively determine how nutrients can impact certain outcomes and, most importantly, how to practically apply this knowledge.

Book Description
Malnutrition and obesity are both common among Americans over age 65. There are also a host of other medical conditions from which older people and other Medicare beneficiaries suffer that could be improved with appropriate nutritional intervention. Despite that, access to a nutrition professional is very limited. Do nutrition services benefit older people in terms of morbidity, mortality, or quality of life? Which health professionals are best qualified to provide such services? What would be the cost to Medicare of such services? Would the cost be offset by reduced illness in this population? This book addresses these questions, provides recommendations for nutrition services for the elderly, and considers how the coverage policy should be approached and practiced. The book discusses the role of nutrition therapy in the management of a number of diseases. It also examines what the elderly receive in the way of nutrition services along the continuum of care settings and addresses the areas of expertise needed by health professionals to provide appropriate nutrition services and therapy.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
Warfighters typically under-eat relative to their energy expenditure during field training and deployments. Maintaining hydration is also a challenge particularly during hot weather, as there is aversion to the smell and taste of warm water, particularly when chlorine is present. A novel nutrient delivery system has been developed to provide Warfighters on-demand access to flavored electrolyte- and carbohydrate-enhanced drinks, to provide hydration, and energy to sustain work. This technical report documents efforts to obtain user feedback regarding the acceptability of an early prototype system. The combined results of two different survey groups (n= 22) reveal that 59% of Soldiers rated the device as a "moderately" to "extremely valuable" and 68% reported that they would be "moderately" to "extremely likely" to use the device if it were available to them. 73% felt it could improve their performance. Recommended improvements included making hardware components more rugged, improving engineering to minimize leakage, adding more positive control of the on-off system, and creating a variety of flavored beverages with high taste acceptability.
