Adequate fiber in the diet is essential for maintaining gastrointestinal and cardiovascular health and for weight management and glycemic control. But a majority of people in developed countries fall short of their recommended daily intake. Designed for product developers, nutritionists, dietitians, and regulatory agencies, Dietary Fiber and Health discusses critical findings from the Ninth Vahouny Fiber Symposium about the significance of dietary fiber and ways to get more fiber in our diet. Steeped in research and the latest data from international experts, the book explores a range of topics related to this essential nutrient, including: The relationship between fiber and weight management, gastrointestinal health, heart disease, cancer, and glucose metabolism Prebiotic effects of fiber and the characteristics and modulation of healthy flora The health benefits of novel fibers such as inulin The characteristics of maltodextrin, Fibersol-2, and low viscous fiber on satiety, glycemia, microbiota, and other properties The impact of the new definition of dietary fiber published by the Codex Alimentarius Commission The properties and immunological impact of Galactooligosaccharide and research on its effect on colitis Resistant starch and associated compounds Oat, rye, barley, and other fibers Regulatory issues, including GRAS notice procedure It is imperative that food product developers formulate foods with fiber and that health professionals recommend foods high in fiber to improve public health. The contributors to this volume provide a survey of not only the impact of fiber on human health, but also the myriad opportunities for fiber ingredients to be incorporated into foods for the benefit of consumers.
Dietary fibre is a broad term that includes non-digestible complex carbohydrates, such as cellulose, hemicellulose, mucilage and colloids, like pectin, carrageenan and arabic, xanthan or guar gum. Dietary fibre is a plant basic structural factor and exists in water-soluble and non-soluble form. Soluble fibre is found in certain fruits and vegetables such as oranges, apples, bananas, broccoli and carrots. It also exists in large amounts in legumes such as peas, soybeans, lentils and beans. Secondary sources include oat bran, soybeans, nuts and seeds. Sources of insoluble fibre are whole grain foods, wheat bran, nuts and seeds. Vegetables, such as green beans, leek, cabbage, cauliflower, broccoli, radish and carrot are high-fibre foods. Purported benefits of fibre include gastro-intestinal health, cardiovascular health, weight management, satiety, glycemic control and prebiotics. Recommended intakes, 2035 g/day for healthy adults and children over age 5, are not being met, because intake of good sources of dietary fibre, fruits, vegetables, whole and high-fibre grain products, and legumes are low. The importance of food fibres has led to the development of a large and potential market for fibre-rich products and ingredients and nowadays there is a trend to find new sources of dietary fibre. In recent years, dietary fibre has received increasing attention from researchers and industry due to the likely beneficial effects on the reduction of cardiovascular and diverticulitis diseases, blood cholesterol, diabetes, and colon cancer. The contributors to this volume provide an assessment of not only the impact of the biological and functional potential of different dietary fibre sources but also their health implications.
It has been acknowledged that the physiological effects of dietary fiber are an exceedingly complex matter which requires a multidisciplinary research effort. The increased scientific involvement of the medical community, nutritionists, chemists and physicists is not only warranted but it has become mandatory. This is because we are entering a more advanced research phase in which the observed . in vivo effects should not be only recorded, but they should be systematically correlated with the physicochemical and analytical properties of the individual dietary fibers. The Division of Agricultural and Food Chemistry of the American Chemical Society has recognized this for some time, and has asked us to organize another International Symposium, similar to one in 1982, which would address the latest developments in this field. We decided to ask a cross section of leading experts from industrial and academic research institutions to assess the state of the art in dietary fiber, namely in the areas of the physiological effects, physicochemical attributes, and in existing and proposed analytical methods. We also felt that chemistry and physical chemistry should playa greater role in fiber research to complement and better explain the existing . in vivo data. There is a large volume of animal and human physiological and nutritional data available. Unfortunately, the generated information is frequently confusing. One reason is that this research is not conducted with well characterized compounds, but rather with loosely defined complex mixtures or entities.
Dietary fibre technology is a sophisticated component of the food industry. This highly practical book presents the state-of-the-art and explains how the background science translates into commercial reality. An international team of experts has been assembled to offer both a global perspective and the nuts and bolts information relevant to those working in the commercial world. Coverage includes specific dietary fibre components (with overviews of chemistry, analysis and regulatory aspects of all key dietary fibres); measurement of dietary fibre and dietary fibre components (in-vitro and in-vivo); general aspects (eg chemical and physical nature; rheology and functionality; nutrition and health; and technological) and current hot topics. Ideal as an up-to-date overview of the field for food technologists; nutritionists and quality assurance and production managers.
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.
Increasing fiber consumption can address, and even reverse the progression of pre-diabetes and other associated non-communicable diseases. Understanding the link between plant dietary fiber and gut health is a small step in reducing the heavy economic burden of metabolic disease risks for public health. This book provides an overview of the occurence, significance and factors affecting dietary fiber in plant foods in order to critically evaluate them with particular emphasis on evidence for their beneficial health effects.
