Vitamin E in Human Health

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 shouldalso 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.

The start of each chapter presents a summary of key chapter points One of few professional texts focusing exclusively on vitamin E Written by distinguished experts in their respective fields

This comprehensive volume examines the role of vitamin E as an essential micronutrient in human health and its extensive clinical benefits. Sections cover a wide breadth of topics, including vitamin E intake and recommended daily allowance, understanding the biological activities of Vitamin E and observed physiological effects, benefits of vitamin E on upper respiratory infections, cardiovascular disease, age-related macular degeneration, Alzheimer's disease, and intake safety. The text serves to emphasize the importance of vitamin E in relation to disease prevention as well as to raise awareness of the number of health conditions where an increased intake of vitamin E can be of potential significance. It explores vitamin E in an up-to-date, science based, applicable real-life perspective and offers pragmatic solutions for its safe and personalized use beyond the various methodological and statistical controversies.

Intended for the medical and nutritional community, Vitamin E in Human Health will not only be an expansive resource for healthcare professionals, but also makes efforts to stimulate increased support for vitamin E research and further exploration of the safe and efficacious use for this essential micronutrient.
