Selenium dietary supplements may raise a person's risk of developing diabetes, not lower it as had been suspected, researchers reported Monday in the Annals of Internal Medicine. People who took a 200-microgram daily dose of the mineral for seven years had a 50% higher risk of developing type 2 diabetes compared with the placebo, the study found. About 60% of Americans take multivitamins, most of which include 33 to 200 micrograms of selenium. In the U.S.

Giving selenium, an antioxidant mineral sold as a dietary supplement, to HIV patients modestly reduced the amount of virus in their blood, according to a study published Monday. Patients taking 200 micrograms of high selenium yeast daily saw an average 12% drop in blood virus levels, according to the study in the Archives of Internal Medicine. "I liken selenium to a lion tamer in a circus," said lead author Barry Hurwitz, a professor of psychology and medicine at the University of Miami.

A dozen wild bird eggs plucked from nests on the west side of the San Joaquin Valley show how easily things can go awry when trying to clean up the region's tainted farm drainage. The eggs, collected last year in fields that are part of a treatment project, contained the same lethal levels of selenium that poisoned migrating waterfowl more than two decades ago at the Kesterson National Wildlife Refuge near Los Banos.

What foods are high in selenium? I've been told this mineral may help prevent arthritis. Research presented in November at the annual meeting of the American College of Rheumatology showed that people with low selenium levels were more prone to osteoarthritis. Brazil nuts are the richest food source of this mineral, with 544 micrograms an ounce. Don't overdo, though. More than 400 micrograms of selenium daily may be excessive.

Whether you get enough of the essential trace mineral selenium may depend, in part, on where you live. Research suggests that people who live in areas with low soil selenium levels (which affect the amount that gets into plants) have higher rates of some types of cancers. * Uses: Selenium contains antioxidants that could help protect the body from free-radical damage. It may also promote better functioning of the immune system and thyroid gland.

Something strange is happening to rodents at a wildlife refuge where thousands of birds were poisoned by selenium years ago. Both male and female reproductive organs were found in one-third of the 87 field mice, house mice, harvest mice and California voles trapped last year on land that once collected toxic runoff at the Kesterson National Wildlife Refuge. Just 3% of rodents trapped there showed such characteristics in 1995.
