Trans-fatty acid assessment


Book Description

Elimination of industrially-produced trans-fatty acids (TFA) from the global food supply by 2023 is a key target of the GPW13. Assessing and monitoring TFA content in the food supply and changes in TFA consumption in the population is one of the key action areas for countries in order to eliminate TFA. A two-day WHO expert consultation was held in Geneva Switzerland on 11 – 12 October 2018 to review and discuss the draft REPLACE “A” module, and draft protocols, and agree on approaches for TFA assessment in food and blood plasma. The consultation brought together 17 TFA experts from 14 countries, representing five of the six WHO regions. This is the meeting report of the expert consultation. The target audiences include policy makers, academic institutions and laboratories conducting TFA assessment.

Analysis of Free Radicals in Biological Systems


Book Description

"Oxidative stress" is used as the generic term describing the involve ment of reactive oxygen species in various human diseases. The scope of such a topic is becoming increasingly wide. The recent interest in radicals such as nitric oxide and the discovery of new mechanisms such as the effect of free radicals on redox sensitive proteins and genes are enlarging our understanding of the physiological role of free radicals. Oxidative stress is involved in numerous pathological. processes such as ageing, respiratory or cardiovascular diseases, cancer, neurological pathologies such as dementia or Parkinson's disease. It still remains difficult, however, to demonstrate by chemical measurement the in vivo production of free radicals and even more to realise their speciation. Therefore, the development of new tools and indicators is engrossing many researchers working in this field. Reliable indicators are abso lutely necessary not only to monitor the evolution of oxidative stress in patients but also to evaluate the efficiency of new antioxidant treat ments. The French Free radical club of Grenoble, the CERLIB has been involved for many years in the organisation of international training programs on methodology, in order to provide both theoretical and practical help to researchers from various countries. Such training sessions have been highly successful and participants value the oppor tunity to learn reliable techniques. This positive echo explains why the researchers of CERLIB decided, with the help of Prof. Dr. B. Kalyanaraman, to publish selected techniques on free radical re search.




Trans Fatty Acids in Human Nutrition


Book Description

In this completely rewritten Second Edition of Trans Fatty Acids in Human Nutrition authors who are recognised international authorities in their field have addressed the major areas of trans fatty acids (TFA) research such as consumption, analysis, biochemistry, synthesis and natural TFA biosynthesis, health effects, food formulation, and also regulation and consumer perception. Each chapter contains the latest references and major advances and breakthroughs in a specific area of trans fatty acids research. Furthermore, the book also includes a discussion of a major issue - the health effects of the natural trans isomers, comparing their effects to those observed for TFA produced during hydrogenation. The availability of so much information in a single volume will help to clarify the major effects of TFA in human nutrition that have been discovered over the last two decades. This book guides the next generation of scientists to the important opportunities for making further progress in this challenging field of research. The First Edition of Trans Fatty Acids in Human Nutrition carried out a very similar task for the state of our knowledge in the late 1990s but the rapid expansion and progress in the subject meant that it had to be completely re-written and expanded from the original nine to the present fifteen chapters of the Second Edition.







Fat Detection

But why are fatty foods so appealing? Why do we crave them? Fat Detection: Taste, Texture, and Post Ingestive Effects covers the many factors responsible for the se




Fatty Acids in Foods and their Health Implications,Third Edition


Book Description

Since the publication of the bestselling second edition, mounting research into fatty acids reveals new and more defined links between the consumption of dietary fats and their biological health effects. Whether consuming omega-3 to prevent heart disease or avoiding trans fats to preserve heart health, it is more and more clear that not only the quantity but the type of fatty acid plays an important role in the etiology of the most common degenerative diseases. Keeping abreast of the mechanisms by which fatty acids exert their biological effects is crucial to unraveling the pathogenesis of a number of debilitating chronic disorders and can contribute to the development of effective preventive measures. Thoroughly revised to reflect the most resent research findings, Fatty Acids in Foods and their Health Implications, Third Edition retains the highly detailed, authoritative quality of the previous editions to present the current knowledge of fatty acids in food and food products and reveal diverse health implications. This edition includes eight entirely new chapters covering fatty acids in fermented foods, the effects of heating and frying on oils, the significance of dietary ?-linolenate in biological systems and inflammation, biological effects of conjugated linoleic acid and alpha-linolenic acid, and the role of fatty acids in food intake and energy homeostasis, as well as cognition, behavior, brain development, and mood disease. Several chapters underwent complete rewrites in light of new research on fatty acids in meat, meat products, and milk fat; fatty acid metabolism; eicosanoids; fatty acids and aging; and fatty acids and visual dysfunction. The most complete resource available on fatty acids and their biological effects, Fatty Acids in Foods and their Health Implications, Third Edition provides state-of-the-science information from all corners of nutritional and biomedical research.




Saturated fatty acid and trans-fatty acid intake for adults and children


Book Description

his guideline provides updated, evidence-informed guidance on the intake of saturated fatty acids and trans fatty acids to reduce the risk of diet-related noncommunicable diseases in adults and children, particularly cardiovascular diseases. This guideline is intended for a wide audience involved in the development, design and implementation of policies and programmes in nutrition and public health. This guideline includes recommended levels of intake for saturated fatty acids and trans-fatty acids and recommendations on preferred replacement nutrients which can be used by policy-makers and programme managers to address various aspects of saturated fatty acid and trans-fatty acid intake in their populations through a range of policy actions and public health interventions.

Trans Fatty Acids


Book Description

Trans fatty acids (TFAs) have been used for many years to impart desirable physical characteristics to fats and fat blends used in food manufacturing. However, clinical trials and epidemiological studies conducted over the last thirty years have shown that TFAs can increase “bad” cholesterol levels in the blood while reducing “good” cholesterol. Accordingly, they are also linked with increased risks of coronary heart disease, thrombosis and strokes. For this reason, the food industry has been obliged to find alternatives to TFAs, thus enabling it to meet the presumed consumer demand for “low” or “no” trans fats products. The issue is becoming more and more pressing. For example, US labelling regulations now require that food manufacturers state the trans fat content of their products on the packaging. This book provides an overview of trans fatty acids in oils and fats used in food manufacture. Topics covered include: the chemistry and occurrence of TFAs; analytical methods for determining the fatty acid composition including TFAs of foods; processing techniques for reducing, minimising or even avoiding the formation of TFAs; TFA alternatives in food; health and nutrition concerns and legislative aspects. It is directed at chemists and technologists working in edible oils and fats processing and product development; food scientists and technologists; analytical chemists and nutritionists working in the food industry.
