Research suggests that selenium can protect humans against cancer of the lung, ovaries, breast, colon, liver, cervix, skin, stomach and uterus. When sufficient selenium levels are achieved, the risk of getting cancer is half that of a person who is selenium deficient. There are few good food sources of selenium, so supplementation may be the best way to obtain selenium's protective benefits.
As an immune supportive mineral, selenium stimulates the development and function of all types of white blood cells and enhances the ability of lymphocytes and NK cells, or killer cells, to activate and respond to invaders such as bacteria and viruses, including the flu. Selenium works synergistically with Vitamin E, A and C as an antioxidant.
In addition, Selenium binds with many toxic minerals such as arsenic, cadmium, lead, and mercury and facilitates their excretion from the body. By detoxifying per oxidized fats, via its role in the enzyme glutathione and peroxidase, selenium inhibits their carcinogenicity (cancer promoting traits). Selenium also counteracts many of the toxic effects of smoking tobacco.
Smoking depletes the body's selenium supplies. In the liver this mineral retards the conversion of hydrocarbons into carcinogens — an important function in our polluted environment. Good food sources include Brasis nuts, brewer's yeast, organically grown vegetables, sesame seeds, garlic, seafood, liver, and mushrooms. However, modern methods of farming and processing foods has depleted their nutritional value of this much needed mineral, along with other essential minerals.
Selenium Supplementation May Reduce Cancer Risk
One in every four deaths in this country is caused by cancer. That's 1,500 people each day. Many of these cancers are caused by our own bad behaviors - tobacco and alcohol use, lack of exercise, and poor diet - which has led researchers to investigate the ability of nutritional supplements to reduce cancer risk.
There's now convincing evidence that selenium(an essential mineral found in various foods such as Brazil nuts and mushrooms) when taken daily as a supplement can significantly reduce the risk of cancer.
In one clinical study, the risk of prostate cancer was reduced 63% in men supplementing with selenium compared to a placebo group. This result has created tremendous interest in the medical community and the National Cancer Institute has funded a much larger study called SELECT (Selenium and Vitamin E Cancer Prevention Trial) that will enroll 32,000 male subjects to better determine selenium's ability to prevent cancer.
