Health Effects of Polyunsaturated Fatty Acids in Seafoods


Book Description

Health Effects of the Polyunsaturated Fatty Acids in Seafoods emerged from the 1985 Proceedings of a Conference on Health Effects of Polyunsaturated Fatty Acids in Seafoods held in Washington, D.C., spearheaded by the National Fisheries Institutes of Health (NIH), the Department of Commerce (DOC), and the National Fisheries Institute (NFI). The conference aims to review the data about the health effects of polyunsaturated fatty acids in seafood; the impact of omega-3 fatty acids on eicosanoid formation, thrombosis, and inflammation; and the role of docosahexaenoic acid in membrane function and metabolism. It also encourages the researchers to study the possible origin of the health effects of seafood in the American diet. Composed of seven parts, the book begins by discussing the summary, conclusions, and recommendations the chairman of each working groups presented during the conference. It also explains the effects of fatty acids on lipoprotein and generation of products of the 5-Lipoxygenase pathway and the membrane functioning and metabolism. Moreover, it discusses the status of the fishery industries worldwide, the different classes of lipids that contain fatty acids, and recipes with seafood as the main ingredient. This book will be of great interest to the scientists such as basic researchers, clinical investigators, and epidemiologists, as well as to health personnel and consumers.




Seafood Choices


Book Description

The fragmented information that consumers receive about the nutritional value and health risks associated with fish and shellfish can result in confusion or misperceptions about these food sources. Consumers are therefore confronted with a dilemma: they are told that seafood is good for them and should be consumed in large amounts, while at the same time the federal government and most states have issued advisories urging caution in the consumption of certain species or seafood from specific waters. Seafood Choices carefully explores the decision-making process for selecting seafood by assessing the evidence on availability of specific nutrients (compared to other food sources) to obtain the greatest nutritional benefits. The book prioritizes the potential for adverse health effects from both naturally occurring and introduced toxicants in seafood; assesses evidence on the availability of specific nutrients in seafood compared to other food sources; determines the impact of modifying food choices to reduce intake of toxicants on nutrient intake and nutritional status within the U.S. population; develops a decision path for U.S. consumers to weigh their seafood choices to obtain nutritional benefits balanced against exposure risks; and identifies data gaps and recommendations for future research. The information provided in this book will benefit food technologists, food manufacturers, nutritionists, and those involved in health professions making nutritional recommendations.

Omega-6/omega-3 Essential Fatty Acid Ratio


Book Description

Studies on the evolutionary aspects of diet and molecular studies included in this volume indicate that human beings evolved on a diet that was balanced in the essential fatty acids (EFA). In fact, the ratio of omega-6/omega-3 EFA was 1/1 whereas present day diets in both developed and developing countries have a much higher ratio, between 5/1 and 50/1. Additional studies show that a high ratio of omega-6/omega-3 EFA is detrimental to health and may lead to the development of chronic diseases. Improving the dietary ratio by decreasing the omega-6 fatty acids and increasing the omega-3 fatty acids is essential for brain function and for the management of cardiovascular disease, arthritis and cancer. A ratio of 4/1 or less leads to lower dosage and to the reduction of adverse effects of drugs. This volume should be of interest to a large and varied audience of researchers in academia, industry, and government; cardiologists, geneticists, immunologists, neuroscientists, and cancer specialists; as well as nutritionists, dietitians, food scientists, agriculturists, economists and regulators.

Seafoods: Chemistry, Processing Technology and Quality


Book Description

Seafoods are important sources of nutrients for humans. Proteins and non protein nitrogenous compounds play an important role in the nutritional value and sensory quality of seafoods. Consumption of fish and marine oils is also actively encouraged for the prevention and treatment of cardio vascular diseases and rheumatoid arthritis. Highly unsaturated long-chain omega-3 fatty acids are regarded as the active components of marine oils and seafood lipids. The basic chemical and biochemical properties of seafood proteins and lipids, in addition to flavour-active components, their microbiological safety and freshness quality, are important factors to be considered. A presentation of the state-of-the-art research results on seafoods with respect to their chemistry, processing technology and quality in one volume was made possible by cooperative efforts ofan international group of experts. Following a brief overview, the book is divided into three sections. In Part 1 (chapters 2 to 8) the chemistry of seafood components such as proteins, lipids, flavorants (together with their properties and nutritional significance) is discussed. Part 2 (chapters 9 to 13) describes the quality of seafoods with respect to their freshness, preservation, micro biological safety and sensory attributes. The final section of the book (chapters 14 to 16) summarizes further processing of raw material, underutilized species and processing discards for production of value added products.

Nutraceutical Fatty Acids from Oleaginous Microalgae


Book Description

Over the past several years, extensive research has been done on the microbial production of polyunsaturated fatty acids (PUFA). Regardless, research on the oleaginous microalgae used as feedstock for biofuels production and the overall story about the production of nutraceutical fatty acids from oleaginous microalgae has been very limited. This volume provides an exclusive insight on the production of nutraceutical fatty acids from oleaginous microalgae and their role on human health. Some saturated and monounsaturated fatty acids can be synthesized by humans, whereas long-chain polyunsaturated fatty acids (PUFAs) such as α-linolenic acid and linoleic acid cannot and are deemed essential. The products of these acids, such as DHA, which is important for early visual and neurological development, are extremely important to human health. Replacing SFAs with omega-3 and omega-6 fatty acids in the diet reduce the risk of cardiovascular diseases and prevent Alzheimer's, bipolar disorder, and schizophrenia, among other benefits. The ever-rising global demand for omega-3 & 6 PUFAs, however, cannot be met solely by fish oil, due to diminishing fish stocks and pollution of marine ecosystems, which has led to increased interest in alternative sustainable sources. Vegetable oils from genetically engineered plant oilseeds and microorganisms are two potential alternatives to fish oil, even though omega-3 PUFAs are highest in the latter. Although transgenic plants present numerous advantages, their production is dependent on seasonal and climatic conditions and the availability of arable land. Moreover, there are public concerns regarding the cultivation of transgenic crops in open ecosystems. These, together with regulatory issues restrict the large-scale production of genetically modified crops. Microorganisms, however, are known natural producers of microbial oils similar to those obtained from plants and animals and a possible source of nutritionally important omega-3 & 6 PUFAs. This groundbreaking volume presents invaluable new research on essential fatty acids, their production from various oleaginous microorganisms, biochemical and metabolic engineering to improve PUFAs content in oil, extraction and purification of omega 3 fatty acids, and the current market scenario. Whether a veteran engineer or scientist using it as a reference or a professor using it as a textbook, this outstanding new volume is a must-have for any engineer or scientist working in food science.




A Framework for Assessing Effects of the Food System


Book Description

How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.




Improving the Fat Content of Foods


Book Description

As health problems such as obesity, heart disease and diabetes increase in many developed and developing countries, the food industry has come under mounting pressure to improve the nutritional quality of its products. Particular attention has focused on the health problems associated with saturated fats in food and on the potential health benefits of increasing monounsaturated and polyunsaturated fat content. Summarising key research in this field, this important collection reviews both the influence of dietary fats on health and practical strategies for improving the fat content of food products.Part one reviews the evidence on the links between dietary fats and health. There are chapters on the links between saturated fatty acid intake, obesity, coronary heart disease, diabetes and cancer, as well as the health benefits of monounsaturated fats, polyunsaturated fatty acids (PUFAs) and conjugated linoleic acids (CLAs). Part two then discusses ways of reducing saturated fatty acids in food. It includes chapters on the role of lipids on food quality and ways of gaining consumer acceptance of low-fat foods, as well as chapters on improving fatty acid composition in dairy products and milk and the use of fat replacers. The final part of the book reviews ways of using polyunsaturated and other modified fatty acids in food products. It includes chapters on developing and using PUFAs as functional ingredients and ways of improving the sensory quality of products incorporating modified fats.With its distinguished editors and international team of contributors, Improving the fat content of foods is a standard reference for nutritionists and product developers in the food industry. - Reviews the influence of dietary fats on health - Investigates practical strategies for improving the fat content of food products - Discusses improving the fat content of foods whilst maintaining sensory quality
