News on Selenium and Heart Disease
Since the 1980s, there have been claims that the trace element selenium, which
contains antioxidants, is good for your heart. People who lived in countries
where the heart disease rate was high tended to be lacking in selenium in their
diets. But in recent years, the thinking on selenium has been changing.
A study published last month in the Journal of Epidemiology looked at more
than 1,000 adults in the U.S. for seven and a half years. Some took 200 micrograms
of selenium per day and some took a placebo. Researchers took health habits
and family background into account, but still found that selenium had no effect
on the risk of developing heart disease.
The study also found that the group of people who took selenium had lower rates
of lung, prostate and colorectal cancer, but it's too early and there's too
little research from other studies to draw any conclusions about that at this
