The Return of W3 Fatty Acids Into the Food Supply


Book Description

This unique publication for the first time brings together scientists from academia, government and industry to discuss the role of omega-3 fatty acids in health, the need to reintroduce them into the food supply, the methods by which this can be accomplished and the state of research. With the domestication of animals, there has been a change in animal feeds, which in turn transformed the composition of meats, particularly the content of essential fatty acids. Changes similar to those in meats have occurred in the composition of eggs, poultry and in fish from aquaculture. Up-to-date reviews on the role of omega-3 fatty acids in health, cardiovascular disease, bone remodeling relative to osteoporosis and in patients with retinitis pigmentosa emphasize the need for a balance of omega-6 and omega-3 fatty acids in the food supply. The reintroduction of omega-3 fatty acids into food products is discussed, and the methods involved in their production as well as their metabolic effects on human beings and companion animals are outlined. Overall, the papers presented indicate the necessity to establish recommended daily intakes for both omega-6 and omega-3 fatty acids. Furthermore, there is a need to redefine food safety; changes in food composition must also be taken into consideration. This unique publication is a valuable source for physicians, nutritionists, dietitians, veterinarians and agriculturalists, as well as for all those concerned with aspects of food production, food technology, food policy and consumer issues.







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.

Nutrition and Fitness


Book Description

Despite the enormous interest in discovering longevity genes in humans, the results have been elusive, while the effects of physical activity in delaying aging are promising and the importance of caloric restriction is now being systematically investigated. At present, there is enough evidence to define the components of a healthy diet and physical activity lifestyle at the population level and it is clear that lack of exercise is associated with increased risk of premature chronic disease and death. Currently, research aims at defining the type and frequency of genetic variation and its influ

Nutrigenetics and Nutrigenomics


Book Description

For the first time, international scientists describe the advances in genetics and nutrition by combining methods of molecular biology with those of functional genetics, also known as systems biology. This book provides the latest data on genetic variation and dietary response, nutrients and gene expression, and the contribution molecular biology has given to systems biology. It also includes a comprehensive critique of genetic association studies in defining the risk of chronic diseases and concludes that molecular diagnostic tests will eventually affect every area of health care from individual risk prediction, early diagnosis of disease, and determination of optimal treatment regimens, to monitoring treatment effectiveness. The appendix contains an extensive glossary of the newly emerging terminology, as well as recommendations for genetic screening. This publication is an essential tool for the future work of all physicians, nutritionists, dietitians, geneticists, physiologists, molecular biologists, anthropologists, food technologists, policy makers, ethicists and educators.




A Balanced Omega-6/omega-3 Fatty Acid Ratio, Cholesterol and Coronary Heart Disease


Book Description

For more than half a century, the relationship between dietary factors and coronary heart disease (CHD) has been a major focus of health research. Contrary to the established view, current data suggest that dietary cholesterol is not a primary factor of or causes heart disease with the possible exception of the genetic forms of familial hypercholesterolemias. For instance, recent clinical trials evaluating the effect of cholesterol-lowering drugs on the development of chronic heart failure, diabetes and stroke have yielded disappointing results. On the other hand, an unbalanced omega-6/omega-3 fatty acid ratio and a cholesterol intake not consistent with the amount during evolution seem to be causal factors in the development of CHD. A panel of international experts in genetics, nutrition, fatty acid, cholesterol, metabolism and coronary heart disease has contributed to this publication, summarizing and critically discussing for the first time the importance of evolutionary aspects of diet, the omega-6/omega-3 fatty acid ratio and cholesterol intake relative to health and CHD. They also propose measuring blood fatty acids in the population in order to define the risk of CHD and other chronic diseases.This book will be of interest to physicians (cardiologists, gerontologists, and pediatricians), nutritionists, dieticians, health care providers, scientists in industry and government and policy makers.
