Free radicals have been implicated in a entire host of different human disease states, which suggests that although they may not have a pivotal causal role, they are involved in the perpetuation of disease. In recent years, it has become evident that although free radicals most certainly do have this role in perpetuating inflammatory reactions, they have perhaps a far more important role in acting as second messenger systems to maintain normal cell function. It is the perturbations of these reactions which pose the most intriguing therapeutic challenges.

What are antioxidants? What do they do? Should you be taking them? How much is enough, or too much? Dr. John Smythies explores these and other questions you need to have answered about antioxidants in Every Persons Guide to Antioxidants. Oxidants are naturally occuring chemicals in our bodies that derive from oxygen to facilitate essential biochemical processes. However, most oxidants are potentially toxic molecules and the body contains a number of antioxidants for protection against these toxic effects. Overproduction of oxidants, or underproduction of antioxidants, leads to oxidative stress, which has been linked to a wide range of chronic diseases, including heart disease, cancer, diabetes, and Alzheimers. Smythies thoroughly evaluates current scientific work on this subject and suggests that a high proportion of many of these diseases can be prevented, or their onset delayed, by proper intake of antioxidants. He examines the pros and cons of the debate over how this necessary intake should be achieved, by eating more fruits and vegetables or by taking supplements in pill form. Smythies surveys the toxicity of antioxidants and recommends under what circumstances they should be given with caution or not at all. He also discusses whether taking supplements requires medical supervision and lists good sources of antioxidants in fruits and vegetables

The current volume entitled, ""Free Radicals and Diseases"" integrates knowledge in free radical-associated diseases from the basic level to the advanced level, and from the bench side to bed side. The chapters in this book provide an extensive overview of the topic, including free radical formations and clinical interventions.
