That daily cup of coffee may be good for your brain.

Drinking coffee has already been linked to a lower risk of developing Alzheimer's. But a new study at the University of North Dakota may explain why.

Researchers fed a high cholesterol diet to rabbits for 12 weeks. Those given a caffeine supplement showed a vital barrier between the brain and the main blood supply. Caffeine showed an ability to stabilize a brain filter and helped block the damage that cholesterol can inflict on the body.

Medical experts are calling this latest finding the best evidence yet of the benefits of caffeine.
