This volume includes contributions presented at the Second International Sym posium on Nutrition and Cancer, held in Naples, Italy, in October 1998 at the National Tumor Institute "Fondazione Pascale." During the Conference, experts from different disciplines discussed pivotal and timely subjects on the interactions between human nutrition and the development of malignancies. Comparing the themes of this Meeting with those discussed at the First Sympo sium in 1992, the major scientific advancements certainly derive from the extensive use of molecular approaches to perform research in nutrition. Moreover, the fundamental observation of R. Doll and R. Peto (1981), which suggested that at least 35% of all cancers (with large differences among different tumors) might be prevented by dietary regimens, has been definitively confirmed by epidemiological studies. On the other hand, the relationships between diet and cancer are quite intricate and complex; it is difficult, and at the same time not methodologically correct, to reduce them to simple terms. Metabolic and hormonal factors, contaminants and biological agents, and deficiency of specific protective nutrients are all pieces of the same puzzle.
This is the first comprehensive volume to look at the importance of short-chain fatty acids in digestion, the function of the large intestine and their role in human health. Short-chain fatty acids are the major product of bacterial fermentation of dietary carbohydrates in the human and animal large intestine. They represent the major end products of digestive processes occurring in the caecum and large intestine. As such, they form an important dietary component and it is increasingly recognised that they may have a significant role in protecting against large bowel cancer and in metabolism. Prepared by an international team of contributors who are at the forefront of this area of research, this volume will be an essential source of reference for gastroenterologists, nutritionists and others active in this area.
This book highlights the important role free fatty acids (FFA) play as potential drug targets. While FFA have long been considered byproducts of cell metabolism, they are now recognized as ligands that regulate cell and tissue function via G-protein-coupled receptors. At least three receptors have been identified for which FFA appear to be the endogenous ligands.
The mammalian gastrointestinal mucosa is a rapidly self-renewing tissue in the body, and its homeostasis is preserved through the strict regulation of epithelial cell proliferation, growth arrest, and apoptosis. The control of the growth of gastrointestinal mucosa is unique and, compared with most other tissue in the body, complex. Mucosal growth is regulated by the same hormones that alter metabolism in other tissues, but the gastrointestinal mucosa also responds to host events triggered by the ingestion and presence of food within the digestive tract. These gut hormones and peptides regulate the growth of the exocrine pancreas, gallbladder epithelium, and the mucosa of the oxyntic gland region of the stomach and the small and large intestines. Luminal factors, including nutrients or other dietary factors, secretions, and microbes that occur within the lumen and distribute over a proximal-to-distal gradient, are also crucial for maintenance of normal gut mucosal regeneration and could explain the villous-height-crypt-depth gradient and variety of adaptation, since these factors are diluted, absorbed, and destroyed as they pass down the digestive tract. Recently, intestinal stem cells, cellular polyamines, and noncoding RNAs are shown to play an important role in the regulation of gastrointestinal mucosal growth under physiological and various pathological conditions. In this book, we highlight key issues and factors that control gastrointestinal mucosal growth and homeostasis, with special emphasis on the mechanisms through which epithelial renewal and apoptosis are regulated at the cellular and molecular levels.
The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.
Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.
Only 15 years ago a conference on dietary fiber, let alone an international conference, would have been considered an extremely unlikely, and in fact an unthinkable, event. Yet in recent years a number of such conferences have taken place at the international level and in different parts of the world; the conference of which the present volume is an outgrowth is the second to have been held in Washington, D. C. This extraordinary development of interest in a hitherto largely neglected component of diet has been reflected by a veritable explosion of scientific literature, with published articles increasing 40-fold, from around ten to over 400 per year, within the decade 1968-1978. Not only has the growth of interest in and knowledge of fiber made it perhaps the most rapidly developing aspect of nutritional science in recent history if not in all time, but epidemiologic studies relating fiber intake to disease patterns, subsequently broadened to include other food components, have been largely responsible for the current concept of diseases characteristic of modern Western culture and lifestyle. The potential importance of this realization is forcefully underlined by the considered judgment of Thomas MacKeown, epidemiologist and medical historian of Birmingham University, England.
Presents the State-of-the-Art in Fat Taste TransductionA bite of cheese, a few potato chips, a delectable piece of bacon - a small taste of high-fat foods often draws you back for more. But why are fatty foods so appealing? Why do we crave them? Fat Detection: Taste, Texture, and Post Ingestive Effects covers the many factors responsible for the se
