Vitamin E is a well described and established fat-soluble essential micronutrient and as such has to be provided to the human body on a regular basis in order to avoid deficiency and maintain a healthy status. This is well established and also reviewed in a number of publications. However, a huge body of evidence has accumulated over the last decade, or so, which provides new insights on the mode of action of vitamin E, and the biological role of the tocopherol isomers, and sheds new light on the role of vitamin E in human health. Both fundamental knowledge gain and new data on the role and challenges of vitamin E as an essential micronutrient, including emerging evidence on clinical benefits, will be addressed to put this essential micronutrient in the appropriate perspective. Given this level of new evidence which has emerged over the recent years, a book on vitamin E will put into perspective the concerns which have been raised on vitamin E and which resulted in a misinformation and confusion of the public regarding the importance of vitamin E for human health. This book will reemphasize that Vitamin E is clearly required for human health and its inadequacy leads to increased risk of a variety of diseases. In addition new data of non-communicable diseases (NCD) dependent on vitamin E status show that a lifetime of low intake increases risks of development, severity and complications of NCDs. This text will put the vitamin E case into an up-to-date, science based, applicable real-life perspective and offer pragmatic solutions for its safe and personalized use beyond the various methodological and statistical controversies. The purpose of this book is also to raise awareness not only in the nutrition and medical community, but also in the public media that there are a number of health conditions where an increased intake of vitamin E can be of potential importance. Further this review should also stimulate funding organizations and agencies to increase their support for vitamin E research in order to facilitate the further exploration of the safe and efficacious use of this essential micronutrient.
This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.
Vitamin E was discovered in 1922 by Evans and Bishop as an essential micronutrient for reproduction in rats. The active substance was isolated in 1936 by Evans and was named tocopherol, although the tocopherols and tocotrienols are actually a group of eight isomeric molecules that are characterized by a chromanol ring structure and a side chain. Providing an overview of the state-of-the-art of the chemistry of vitamin E, this book reflects the issues stemming from the complexity of the role and actions in vivo as well as in vitro. It summarizes information on the properties and function of vitamin E, the current understanding of the advantages and limitations of it, and also its application in promotion of health and prevention of diseases. Based on sound, solid scientific evidence, this is a timely addition to the literature as the centennial anniversary of the discovery of this important vitamin approaches.

Over 20 experts from around the world share their wisdom on a topic of central relevance to all equine practitioners and the equine community generally. Both basic and applied (including healthy and diseased animals) nutrition and feeding management of horses and other equids (i.e. ponies, donkeys, wild equids) are covered. The book will appeal to a wide audienc: undergraduate and post-graduate students in equine science and veterinary medicine, veterinarians, equine nutritionists, horse trainers and owners. The clinical component will strengthen the appeal for equine veterinarians. Equine Applied and Clinical Nutrition will be a "must have" for anyone involved in the care of horses, ponies and other equids. The book is divided into 3 parts: - Basic or core nutrition in this context refers to digestive physiology of the horse and the principles of nutrition. - Applied nutrition deals with the particular types of foods, and how to maintain an optimum diet through various life stages of the horse. You might characterize this aspect as prevention of disease through diet. - Clinical nutrition covers various diseases induced by poor diet, and their dietary treatment and management. It also looks at specific feeding regimes useful in cases disease not specifically induced by diet. - Authoritative, international contributions - Strong coverage of clinical aspects either omitted from or only sparsely dealt with elsewhere - Full colour throughout - The only clinical equine nutrition book
Vitamin E is a group of fat-soluble compounds found in a wide variety of foods. Daily requirements of vitamin E can be met with a balanced diet. High-dose supplementation may be hazardous rather than beneficial. Vitamin E serves as an antioxidant, participates in anti-inflammatory processes, inhibits platelet aggregation, and enhances immunity. Vitamin E supplementation can be beneficial against coronary artery disease, eye disorders, cognitive decline, cancer, and skin aging. This book will mainly focus on the diverse functions of vitamin E, importance of vitamin E status to provide a healthy lifespan, and the interaction between vitamin E and several pathological conditions. Readers will receive a general overview of the importance of vitamin E in health and different pathological conditions.

The first demonstration of the existence of a vitamin and the full recognition of this fact are often attributed to the work of McCollum, who found that a sub stance in butterfat and cod-liver oil was necessary for growth and health of ani mals fed purified diets. It became obvious that an organic substance present in microconcentrations was vital to growth and reproduction of animals. Following the coining of the word vitamine by Funk, McCollum named this fat-soluble sub stance vitamin A. We can, therefore, state that vitamin A was certainly one of the first known vitamins, yet its function and the function of the other fat-soluble vitamins had remained largely unknown until recent years. However, there has been an explosion of investigation and new information in this field, which had remained quiescent for at least two or three decades. It is now obvious that the fat-soluble vitamins function quite differently from their water-soluble counter parts. We have learned that vitamin D functions by virtue of its being converted in the kidney to a hormone that functions to regulate calcium and phosphorus metabolism. This new endocrine system is in the process of being elucidated in detail, and in addition, the medical use of these hormonal forms of vitamin D in the treatment of a variety of metabolic bone diseases has excited the medical com munity.
The first 90 years of vitamin E research has produced prolific and notable discoveries, but until the last few decades, attention has been given mostly to the biological activities and underlying mechanisms of alpha-tocopherol, which we now know is one of more than eight vitamin E isomers. Currently, the non-tocopherol vitamin E molecule tocotrienol has reached a new measure of research height: more than one-third of all vitamin E tocotrienol research of the last 30 years has been published since 2009. The thriving field of tocotrienol research gives ground for publication of Tocotrienols: Vitamin E Beyond Tocopherols, Second Edition, a compilation of the latest tocotrienol research in all new chapters. Highlights Established research, including prevention and treatment of cardiovascular disease, metabolic syndrome, and cancer Emergent research, including angiogenesis, bioavailability, bone health, gastric injury, inflammation, life extension, and skin health Tocopherol interference with tocotrienol functions All new chapters and many new contributors Recognized as potent antioxidants, tocotrienols play a role in cholesterol reduction, tumor suppression, reversal of arteriosclerosis, and protection of the heart against oxidative stress. Compiling contributions from leading researchers, this book overviews tocotrienols, and examines their sources, chemistry, and mechanisms of action. Contributors discuss the role of tocotrienols in the treatment and prevention of cancer and in cardiovascular health, diabetes, and other hormone regulation by tocotrienols. In addition, the book addresses animal and in vitro as well as mechanistic and pre-clinical studies. Dr. Tan discusses the benefits of tocotrienol in a YouTube video.
