Free radicals are molecules that react readily with other substances in the body, and this can have negative effects on health in certain circumstances, through the damage caused to cells. Free radicals can be counteracted by substances known as 'antioxidants', which are common ingredients in many dietary supplements. The idea that free radicals are generally dangerous and must be counteracted is, however, a myth, according to scientists who have conducted a new study of the role that free radicals play in heart physiology.Still think they have any idea what they are talking about?
"As usual, it's a case of everything in moderation. In normal conditions, free radicals act as important signal substances, but very high levels or long-lasting increases can lead to disease", says Professor Håkan Westerblad, who has led the study...
"Free radicals play an important role, since they contribute to the heart being able to pump more blood in stress-filled situations", says Håkan Westerblad. "On the other hand, persistent stress can lead to heart failure, and chronically increased levels of free radicals may be part of the problem here."
