Fats in foods and fat on the body have become national obsessions. With due cause. Research is showing the far-reaching deleterious effects of obesity as well as relationships between lipid (fat and oil) consumption and a wide range of health concerns. In this seminal book, Dr. Wysong brings a surprise and reveals that fats are not the nutritional demons popularly assumed. The key to health is not to avoid dietary fat and jump on the cholesterol checking and drug band wagon. Lipids are a part of every cell and are essential components of hormones and body regulators. Even cholesterol (in its natural state) is critical to health. If it is not eaten, the body produces it. Dr. Wysong provides the understanding necessary to avoid such popular and professional myths.Natural fats are not something to avoid, but rather to seek and cherish. The real villain is food processing. Heat, light, air, hydrogenation, and time are the enemies of healthful fats. Not only does processing destroy important fats and oils, but it can convert them to dangerous disease-producing toxins. Dr. Wysong explains how to choose foods that are protected from these dangers.Read carefully, Lipid Nutrition can be one of those rare books which replaces the reading of dozens of others. Whether you are a person just concerned with better health and nutrition, or a professional seeking keys to prevention and treatment, Lipid Nutrition will prove to be a wonderful aid to understanding and a valuable resource for making healthy decisions.

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.

Ever since the publication of Ancel Keys’ watershed ‘Seven Countries Study’ in 1970, medical thinking has posited a causal link between the intake of animal fats and coronary heart disease. The research of Prof. Harumi Okuyama and his colleagues presented in this new publication suggests that this link is in fact tenuous. It goes beyond that to suggest that current medical wisdom regarding lipid nutrition may actually be counterproductive. This ground-breaking analysis is likely to be debated for many years to come. The ‘Seven Countries Study’, which identified the specifics of the Mediterranean Diet and awarded it a central position in combating coronary heart disease, triggered significant changes in Western diets. Most notably, it stimulated a widespread attempt to reduce animal fats and replace them with vegetable fats. The low-density lipoprotein (LDL) element of the cholesterol naturally present in animal-source foods was dubbed a killer, and a significant industry developed around the provision of plant-based oils and fats. The clinical consensus on cholesterol was further strengthened in 1987 by the introduction of statins, an innovative class of drugs that reduce LDL production in the liver and are designed to help guard against coronary heart disease. Thirteen Nobel Prizes have been awarded to scientists who devoted major parts of their careers to cholesterol research. It is therefore a brave research team that dares to challenge the link between animal fats and coronary heart disease. This, however, is precisely what Prof. Okuyama and his team set out to do in this book. They actually recommend increasing the intake of cholesterol and animal fats, to an extent that does not lead to obesity. This recommendation is based on the discovery by Prof. Okuyama and his team that common vegetable oils such as canola and hydrogenated vegetable fats have toxic effects. They demonstrate that hydrogenated vegetable fats and oils are important culprits in atherosclerosis and other lifestyle diseases, and suggest that high total or LDL-cholesterol is not the cause of atherosclerosis or cardiovascular disease. Further, they argue that current medical guidelines on lipid nutrition conflict with evidence-based research, and that persistently focusing on LDL-cholesterol as the cause of atherosclerotic cardiovascular disease (ASCVD) is counterproductive. Key findings Some types of vegetable fats and oils exhibit stroke-inducing and endocrine-disrupting activity. Their inhibition of the vitamin K2–osteocalcin link is the major cause of ASCVD and related diseases. In the current food environment, the balance of omega-6 and omega-3 fatty acids is too much in favour of omega-6, and therefore lowering the omega-6/omega-3 ratio is recommended for the prevention of allergic and inflammatory diseases including ASCVD and cancer. Atherogenesis can develop without elevated LDL-cholesterol levels and/or in association with decreasing LDL-cholesterol levels. Increased intake of vegetable fats and oils with stroke-inducing and endocrine-disrupting activities in countries with restricted intakes of animal fats and cholesterol has led to the critical situations surrounding physical and mental health currently seen in Japan, East Asia, and the Mediterranean countries. Medical care professionals continue to insist on actively reducing LDL-cholesterol levels. This approach will only heighten the extensive health problems that Japan and some countries are at present facing. Many aspects of current medical practice in Japan are indeed likely to be in conflict with that country’s Medical Care Act. This thought-provoking analysis of one of the major health syndromes of our day demands serious consideration by professionals interested in cardiovascular health in particular and in public health more widely. Its implications are far-reaching – for medical practitioners, medical insurers, nutritionists, food producers and pharmaceutical manufacturers alike, as well as for individual patients.

Functional Dietary Lipids: Food Formulation, Consumer Issues and Innovation for Health discusses this important component of the human diet and the ways it plays an essential functional role in many foods. The book covers the functionality and nutritional benefits of dietary fat in food in terms of formulation, manufacturing, and innovation for health. After an introduction by the editor reviewing the role of fats in the human diet, the book discusses the chemistry of edible fats, manufacturing issues, including the replacement of trans-fatty acids in food, fat reformulation for calorie reduction, thermal stability of fats, and the flavor and functional texture and melting characteristics of fats in food. Subsequent chapters address the effect of dietary lipid intake on various health issues and the potential health benefits of bioactive compounds in dietary lipids, with final sections discussing issues that affect the consumer relationship with fat, such as regulation, marketing, and health claims. - Comprehensively examines the functionality and nutritional benefits of dietary fat in food - Discusses the chemistry of edible fats, manufacturing issues, including the replacement of trans fatty acids in food, fat reformulation for calorie reduction, thermal stability of fats, and more - Considers manufacturing issues of dietary fat in foods - Addresses issues affecting the consumer relationship with fat, such as regulation, marketing, and health claims

Les substances lipidiques ont longtemps été négligées par les physiologistes, mais des recherches épidémiologiques les ont récemment portées sur le devant de la scène, notamment au travers de leur intérêt dans les domaines de la nutrition et surtout de la santé chez l’Homme. Outre leur importance énergétique, les lipides interviennent dans de nombreux mécanismes cellulaires dont les dérèglements peuvent conduire à des pathologies parfois graves. En effet, en plus de leur impact sur les maladies métaboliques, les systèmes cardiovasculaire et immunitaire et les processus de cancérisation, le système nerveux central peut lui aussi être altéré à des degrés divers par une carence ou un déséquilibre entre les constituants lipidiques ingérés. Après quelques rappels historiques sur la découverte des lipides et leur utilisation, une première partie décrit les principaux lipides présents dans notre ration alimentaire. Puis, les besoins avérés ou éventuels de l’Homme en divers acides gras, stérols et vitamines appartenant au groupe des lipides, sont passés en revue. Enfin, l’impact des principaux lipides sur des pathologies naguère encore peu explorées sous cet aspect est exposé en détail. Les lipides – Nutrition et santé présente, de façon synthétique, un très large panorama de toutes les facettes des lipides, des acides gras aux corps gras les moins abondants, mais tout aussi importants pour l’équilibre de notre organisme. Il permet aux spécialistes de revisiter les principales sources de lipides présentes dans notre alimentation en insistant sur leur production et leur composition. Cet ouvrage s’adresse aux chercheurs, médecins généralistes et spécialistes, diététiciens et étudiants évoluant dans de nombreux domaines tels que la biologie cellulaire, la nutrition ou encore la pharmacologie.

Our understanding of the physiological function of insect essential lipids has long been flawed by major uncertainties. It was discovered long ago that dietary sterol is a necessary nutrient for all insects, which radically sets them apart from the vertebrates in terms of qualitative nutrient requirements. Because of the physiological importance of sterol as a molting hormone precursor in insects and the implications of this for the development of new insecticides, a wealth of investigation into insect sterol metabolism followed, covering both the ways in which insects convert diverse food-plant sterols into the major tissue sterols and how these in turn are metabolized into the ecdysone molting hormones. However, for the classes or essential Lipid nutrients required by vertebrates, research dealing with insects has been scant and, more often than not, rather indeterminate. Many, but by no means all, insects studied appear to require essential fatty acids, though virtually nothing has been found out about the metabolism or essential physiological function of these acids. Excepting vitamin A, needed for insect vision, the various vertebrate fat-soluble vitamins appear to have no significance for insect physiology, and results of the occasional attempts to demonstrate functions for them in growth and development have in most cases been tantalizingly equivocal. In recent years some notable advances were made in tne study or essential fatty acids and fat-soluble vitamins in insects, and work on insect sterol nutrition and metabolism continues with ever-increasing sophistication. The contributors to this book summarize, discuss, and speculate on these issues. Their work is based on papers presented at the 1980 World Congress of Entomology at Kyoto, Japan.
