Product Description

A clearly-written guide to antioxidants - what they are, what they do and information to decide if, when, why and how they should be a part of your diet. Millions of people take vitamins to supplement their diet, believing these pills and powders will help maintain good health and ward off illness. This belief drives an enormous industry for manufacturing, packaging and distributing vitamins. In addition to the thousands of drug store and supermarket shelves stocked with vitamin bottles, there are more than 11,000 health food stores and nutrition centres in the United States that sell only vitamins and their related products. One type of vitamin, antioxidants -including familiar vitamins as C, E, beta-carotene and melatonin, as well as dozens of lesser known antioxidants - has become especially popular and equally controversial. However, reliable information about this important subject has been scanty. Oxidants are naturally occurring chemicals in our bodies that are derived from oxygen to facilitate essential biochemical operations. For example, white blood cells of the body's immune system attack and kill invading pathogenic bacteria and viruses. The weapons they use to do this include highly poisonous oxidants. It is the role of antioxidants to counteract oxidative stress, which consists of the overproduction of these otherwise useful chemicals or failure of normal antioxidant mechanisms. Oxidative stress has been linked to the development of a wide range of chronic diseases, including coronary heart disease, cancer, diabetes, asthma, Alzheimer's disease, schizophrenia and AIDS. Smythies surveys and evaluates the current scientific work on this subject in detail and suggests that a high proportion of many of these diseases can be prevented, or their onset delayed, by attention to the proper intake of antioxidants in the diet. He examines the debate over whether this necessary intake can be achieved by increasing the amount of fruits and vegetables in the diet or whether supplements are needed. Smythies surveys the toxicity of antioxidants and under what circumstances they should be given with caution, or at all. He also discusses whether medical supervision is necessary for someone planning to take supplements, and lists good sources of antioxidants in fruits and vegetables.

Review
Smythies clear explains the basic science of antioxidants and then describes the actual studies supporting the importance of these nutrients to health promotion and disease prevention, providing a strong foundation for his practical advice about diet and supplements. It's a rare treat to see full citations provided for follow-up by the interested reader. -- Jeffery B. Blumberg, Chief, Antioxidants Research Laboratory; Jean Mayer USDA Human Nutrition Research Center on Aging, Tuffs University

Smythies takes an extremely detailed and comprehensive look at the current scientific knowledge of the role of antioxidants in human health. A book for the educated lay person that's well balanced and free of the hype that often accompines the topic of antioxidants! -- Balz Frei, editor of Natural Antioxidants in Human Health and Disease

Thorough and documentated
My ony complaint about this book is that Professor Smythies is a little bit too professorial. There were parts where I really had to concentrate and re-read in order to understand his explanation. However, he is very thorough in his explanaiton of the varieties of anti-oxidants and how they help maintain good health. Unfortunately, we don't get enough of the in our foods these days and must turn to supplements. His cautionary advice is good too.
