4 Your Health: questioning bone protecting vitamins; air pollution worse for seniors.

Posted: Updated:

Air pollution poses serious health risks to older adults.

That's according to a new study from Harvard University. Researchers found short-term exposure to ozone and fine particulates, even at levels below national standards, was linked to early death in senior citizens.

The risk was even higher among elderly who were low-income, female or black. Experts said no matter where you live, breathing in bad air is dangerous.

Limits to vitamins preventing bone fractures

A separate study of elderly adults reveals calcium and vitamin-D supplements do not protect against bone fractures.

Scientists in China tracked over 50,000 seniors. People who took vitamin-D, calcium, or both, did not have a lower risk of bone breaks regardless of the dose, sex of the patient, or their fracture history.
