Daily coffee can protect your brain

Drinking coffee could reduce the risk of dementia by protecting the brain from the damage cholesterol can cause, it has been claimed.

It is thought the caffeine content helps create a barrier between the blood supply and the brain protecting the central nervous system from harmful chemicals in the bloodstream.

Dr Jonathan Geiger of the University of North Dakota said tests which have been conducted on rabbits could now help battle Alzheimer's because high levels of cholesterol are a risk factor for the disease.
