PHILADELPHIA (CBS) - Falls are a major problem in the elderly and they can be a leading cause of injury and long term health issues. In addition to that, people who have osteoporosis are at dramatically increased risk for fractures. So how can this be prevented?

The first step is nutrition. Among elderly people, proper nourishment and supplementation with vitamin D was shown to not only help strengthen bones but reduce falls.

Another major benefit came from exercise. Not extreme exercise but lifting with light weights and flexibility drills can help.
