I found an interesting, rather profound and comprehensive article on the runnersweb on oxidants and antioxidants. http://www.runnersweb.com/running/rw_news_frameset.html?http://www.runnersweb.com/running/news/rw_news_20060724_ERB_Antioxidants.html
It thoroughly reviews the latest studies, and does not simply recommend substitution by all means.
Scientifically evaluated the debate on oxygen free radicals is still controversial. There is no clear-cut data that place antioxidant substitution beyond all doubts. Free radicals are not only harmful, they are for good as well, they help to remove tissue debris, kill bacteria, and they speed up metabolic processes in cells. In a healthy body radicals and the corresponding buffer systems are usually in balance. Of course, a body under excessive strain produces a surplus of radicals which might not be able to be compensated by its naturally occurring buffer systems.
Therefore the diet of an endurance athlete should consider the intake of antioxidant foods (fruits, vegetables) as essential. And in extreme cases and under extreme circumstances substitution may be taken into consideration.
But please, keep in mind, radicals are not bad per se.
I would like to ask you two questions here at this point.
1. Since when are you acquainted with antioxidants?
2. What do personally think about them?
