Nutrition Tip: Know about Selenium

- By Shari Liberman, PhD, CNS, FACN

In humans, a link has been found between selenium and heart disease. People found to have overt selenium deficiencies - alcoholics with cirrhosis of the liver and people receiving long-term intravenous feeding - have also been found to suffer from heart problems that respond to selenium supplementation.

In eastern Finland, which has one of the highest mortality rates from heart disease in the world, it was found that low selenium in the blood was associated with up to a six - or sevenfold increase in the risk of death from heart disease. In addition, children in certain areas of China in which the selenium content of the soil is low are known to develop a heart disease called Keshan's disease. Their heart problems, too, respond to selenium supplementation.
