Mineral can prevent knee osteoarthritis
So you dislocated your knee on the soccer field and you're worried about future joint problems? Don't stress: Ingesting the mineral selenium can prevent severe knee osteoarthritis, according to research from the University of North Carolina at Chapel Hill. Researchers assessed the selenium levels in 940 osteoarthritis patients and compared those levels to x-rays of patients' knees. Patients with the highest selenium levels had 55 percent lower odds of having moderate or severe knee osteoarthritis. It doesn't take much to reap the benefit ó 55 micrograms of selenium daily is enough, says study author Joanne M. Jordan, M.D. You can get it from about 4 ounces of light tuna (canned in oil), 7 ounces of cooked beef, or enriched grains.
