The Benefits of Selenium
Although it doesn't get much credit, selenium could be your best bet in preventing cancer. Selenium is in many foods, and you probably didn't even know it. All selenium that is found in animal tissue is found in their proteins, or they can be found naturally in nuts and liver.
Much of the testing that has been done over the past years prove the effectiveness of selenium in animals, but in 1996 a study was conducted at the University of Arizona in Tuscon proved the same theory in humans.
People who were given 200mg of selenium a day for four years reduced their chances of getting cancer by 32%, and their risk of dying from cancer by 50%. Additional research shows that people with a certain genetic makeup benefit more from the supplement selenium.
