Supplement Selenium to Stay Healthy
Tuesday, October 17th 2006
A study recently came out reporting that this essential mineral on its own doesn't prevent heart disease. That's what the headlines focused on, but the real story was much more positive.
Selenium - significant cancer fighter
Selenium appears to be a significant cancer fighter. In fact, that was the actual point of the study - to determine how well selenium worked in the battle against cancer. The results were stellar: After more than seven years of taking daily 200-microgram selenium supplements, participants enjoyed a much lower risk of several cancers (compared to the subjects who got the placebo). Like 26 percent fewer cases of lung cancer, 52 percent fewer cases of prostate cancer, 54 percent fewer cases of colorectal cancer, and 41 percent fewer overall cancer deaths.
Other studies have indicated that selenium deficiencies may contribute to blood vessel damage brought on by oxidative stress, a condition causing structural damage to cells. Selenium's antioxidant powers help prevent that oxidative stress - particularly when it's consumed along with other nutrients like vitamins C, E and B3.
Selenium helps thyroid function
Selenium is also critical for optimal thyroid function. This mineral not only helps the thyroid gland fulfil its hormone-producing responsibilities, it also makes sure that the right amount of hormones are produced. Low levels of selenium have also been linked to rheumatoid arthritis, and studies are under way to see if selenium supplements can help treat this extremely painful condition.
The current RDA for selenium (for adults) is 55 micrograms (mcg), but studies put the cancer-preventing dose at 200mcg daily. Apparently some of the best sources are seafoods - just 11 gm of shrimp, cold, snapper, or halibut should provide over 50mcg of Selenium. The mineral is also abundant in roasted turkey bread, dried sunflower seeds, rye and barley. The current NZ Dietary Supplement Regulations 1985 sets the limit for Selenium at 150mcg per daily dose.
