Book Description
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.

Book Description
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

Book Description
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.
