May 23, 2012 - The Food and Drug Administration is approving the first drug to prevent HIV. The drug, Truvada was approved in 2004 to treat people already infected with HIV. The experts are basing their decision on groundbreaking studies conducted among gay men and heterosexual couples at high risk of becoming infected with HIV. Those trials showed that Truvada cut the risk of new infection by at least 44 percent in healthy gay and bisexual men and by 73 percent in heterosexual couples in which one partner had HIV but the other did not.
Also, if high blood pressure runs in your family, there is something you can do about it. Moderate exercise, and better cardiovascular fitness can significantly reduce your risk of having high blood pressure. Researchers at the University of South Carolina studied more than 6 thousand people, and those who were fit, had a 34 percent lower risk of developing high blood pressure, even if they had a parent who had the disease.
