A new study on osteoporosis shows that calcium-rich diets can combat thinning of the bones among young women athletes if the condition is detected early.Researchers from the University of California Medical Center at San Francisco studied young woman athletes who suddenly stop menstruating, a group that has been known for several years to suffer reduced bone mass, putting them at high risk for osteoporosis.

The UCSF team found that bone mass remains 12 percent lower than normal as long as 10 to 15 years after the athletes' periods had resumed, but also found that increased dietary calcium could partly restore bone density in that group.
