[PRESS RELEASE, 28 February 2011] Fear of free radicals may be exaggerated, according to scientists from Karolinska Institutet. A new study, published in The Journal of Physiology, shows that free radicals act as signal substances that cause the heart to beat with the correct force.
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.
"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.
