'Good' cholesterol may lower Alzheimer's risk

WASHINGTON A new study out of Columbia University in New York City followed more than 1,100 seniors who had no history of memory trouble or dementia.

Researchers studied the participants for four years.

They found that the people with the highest HDL, or good cholesterol, levels had about a 60-percent lower risk of developing Alzheimer's disease.

The study did not provide an explanation for the link.

Exercising, eating more soy and taking omega three fatty acid supplements are a few ways to boost HDL levels.
