Antioxidants play an important role in the progression of major human degenerative diseases and conditions. This book covers antioxidants and their mechanisms of action; their role in a whole array of conditions including coronary heart disease, malignant disease, diabetes, cataracts, respiratory disease, cystic fibrosis, cognitive functions, and aging; their indicators for oxidative stress; and consumer issues. The majority of chapters have been developed from papers presented at the 6th World Congress in Clinical Nutrition, held in Banff, Canada, July 1997.
