Study: Link ties Vitamin D deficiency to dementia

A new study suggests a link between Vitamin D and dementia.

Among people over the age of 65, researchers say those who are moderately deficient, more than double their risk for developing dementia. For those who are severely lacking, the risk increases to 125 percent.

You can get Vitamin D by eating more salmon, mushrooms and fortified dairy or you can go outside and get more sun.

Researchers say people should aim for 20 minutes a day, three times a week.
