Dietary Proteins and Atherosclerosis provides a thorough review of the role of proteins in the development of atherosclerosis. The author reviews early research connections between dietary fat and cardiovascular disease caused by the build-up of plaque in arteries and examines other factors that contribute to atherosclerosis, such as infection and dietary proteins. Relying on data obtained from almost 2,000 research articles and literature reviews, the author provides a thorough analytical examination and discusses how emphasis on the role of dietary fat in atherogenesis has overshadowed the critical contribution of dietary proteins to the development of cardiovascular disease.
Analyzes the effects of dietary animal, vegetable and fish proteins on serum cholesterol levels in animal models and humans. Explores the possible mechanisms which have been advanced to date and reports the results of original research inquiries.
Atherosclerosis which accounts in Western Europe for more than 40 % of deaths, is a generalized disease that develops slowly and is symptomless until lesions have become sufficiently severe to cause myocardial or cerebral infarction. Research on specific and precocious markers of atherosclerosis and the development of non invasive techniques for their early detection represent major challenges in biomedical field. We hope that this volume of edited papers, a consequence of the third international colloquium on atherosclerosis, conducted at the University of Brussels, Belgium through the support of the "Fondation de Recherche sur l' AtherosclE,rose" will contribute to this goal. Among the topics discussed the major ones were the mechanism of action of lipolytic enzymes, the deficiency or dysregulation of cellular receptors, the genetic deficiencies of apolipoproteins, and the panoply of external factors as diet, physical exercise, drugs, which mOdify the lipoprotein metabolism. Special interest was also devoted to potent techniques as kinetic analysis of metabolic tracers and use of monoclonal antibodies. Their contribution to the detection and treatment of atherosclerosis will be obviously essential in the future.
Abstract: Nine papers developed from a 1981 international workshop summarize current knowledge of the role of proteins (and amino acids) in lipid metabolism and atherosclerosis for nutritionists, clinicians, and other health professionals. The topics range from studies on lipid metabolism and experimental atherosclerosis in animals (rats, rabbits, swine), to effects of proteins on human serum lipids and lipoproteins. Other papers discuss the effects of soy protein and casein, influences of dietary protein on serum cholesterol, and the immunological aspects of atherosclerosis. The results of these studies indicate that dietary protein can make a significant contribution to atherosclerosis, that soy protein produces lower serum cholesterol levels than casein (the dynamics of which are described), and that diets containing animal protein are generally more cholesterolemic and atherogenic (in rabbits, specifically) than diets containing vegetable protein. The protein effect can be modified by other dietary components (e.g., fiber, fat). Other findings (e.g., the role of dietary protein in the immunological aspects of atherosclerosis) also are reported. (wz).
This volume comprises the proceedings of the sixth International Symposium on Drugs Affecting Lipid Meta bolism. Since the first of these symposia in 1960 these triennial meetings have been devoted to the exploration of new ideas, new data and new concepts related to lipid metabolism and atherosclerosis. The sixth Meeting was particularly stimulating in this regard. The concept of the "protective" action of HDL was thoroughly explored within the framework of its molecular biology with data on its epidemiological as well as its in vitro mechan ism(s) of action being discussed. The action of drugs on arterial and HDL metabolism was also discussed as were newer aspects of platelet aggregation, especially as related to prostaglandins. New ground was also broken in discussions of lipid mobilization and mechan isms of hypocholesteremia. We are indebted to the many organizations who con tributed generously to the support of this meeting. Among the sponsors, the assistance of the Lorenzini Foundation was especially helpful. As in all meetings of this type, the hard work of the local organizing committee was instrumental in its success. We are grateful to Mrs. Caroline Hyatt and Mr. Ralph Hollerorth for their invaluable help in the secretariat. We are also deeply indebted to Miss Jane T. Kolimaga for her expert assistance in the preparation of this volume. David Kritchevsky Rodolfo Paoletti William L.
