Vitamin D For Healthy Bones

Vitamin D For Healthy Bones - High doses of vitamin D increase the number of falls and fractures in older women, say Australian researchers, who warn against using the vitamin in this way.

Geoff Nicholson, of Barwon Health and the University of Melbourne in Geelong, and colleagues investigated the impact of a single annual high-dose of oral vitamin D on older women.

"We expected to find a reduction in falls and fractures but we found exactly the opposite," says Professor Nicholson, whose findings appear today in the Journal of the American Medical Association.

Vitamin D is needed in order for the body to absorb calcium, necessary for healthy bones.

It also plays a role in keeping muscles strong, especially those around the limb girdles.

Professor Nicholson says while the Sun is a major source of the vitamin, indoor lifestyles and the advent of anti-skin cancer campaigns have contributed to low vitamin D levels.

"A good proportion of the population, particularly women who are older, have lower vitamin D levels than are considered healthy," he said.

Man Hits Teen on Plane Over iPhone

Man Hits Teen on Plane Over iPhone - Police say a man on a Southwest Airlines flight from Las Vegas punched a teenager who refused to turn off his iPhone as the plane approached the Boise airport. Officers arrested 68-year-old Russell E. Miller, of Boise, on suspicion of misdemeanor battery Tuesday. He has been released from jail on bond. Witnesses told police the 15-year-old was playing games and listening to music on his cell phone when flight attendants instructed passengers to turn off their electronic devices because the plane was landing. Witnesses told police that when the teen didn't respond, Miller got angry and punched the boy in the arm. Miller says he "tapped" the teen on the shoulder after he refused to turn off the phone. He told the Idaho Statesman that he may have "overreacted," but that he did not punch the teen. Man Hits Teen on Plane Over iPhone
