Free radicals contained in the blood and considered harmful, in fact can protect the heart from disease. Molecules that lead to oxidation and have often been associated with cancer are generally regarded as extremely harmful to the body, reports The Telegraph.

Companies engaged in dietary supplements, on this made a fortune. They insisted that, taking, for example, vitamin C, you can save yourself from a whole series of diseases by suppressing free radicals. However, a recent study conducted at King's College in London and sponsored by the British Heart Foundation revealed: free radicals are able to stimulate the body, forcing to protect the heart. This statement sheds light on why the antioxidant therapy trials failed.

Commented Aya Shah, a professor of cardiology at King's College: "The bad reputation of free radicals makes antioxidants an unusually popular remedy, however, the tests of the latter did not reveal any advantages. Now we know why ".

Scientists have observed what effect the enzyme leading to oxidation, Nox4, has on the hearts of mice. They tested the effect by creating mice that did not have Nox4, and rodents, in which Nox4 was in abundance. It turned out that mice with excess Nox4 better adapted to stress, protecting the heart. Despite the results, experts still do not know how the antioxidants contained in the products affect the blood circulation and heart health.
