Free radicals call molecules that cause oxidation in the blood. Since their activities associated with the development of cancer, the scientists have long considered these molecules are harmful to human health. Companies that produce various additives, made a fortune in manufacturing and selling antioxidants Struggling with activity free radicals .
But a new study conducted by researchers from King's College London, funded by the British Heart Foundation, found that free radicals can stimulate our body to protect against heart disease. This finding provides a possible reason why almost all the impact studies antioxidants to protect the heart have failed.
"Bad reputation free radicals It forced many of us to believe that fighting them antioxidants useful for the cardiovascular system - says professor of cardiology Ajay Shah. - But all the studies that had to confirm it, failed. Our discovery may partially explain this phenomenon. In fact, some of these reactive molecules have exactly the opposite effect - they protect our heart. "
Professor Shah found that there are "harmful" free radicals And are useful. And in the future, scientists need to develop targeted therapies that will reduce to a minimum the impact of some and to support others.
