Drink a cup of coffee a day is not only a stimulating effect, but also protects the brain from the harmful effects of cholesterol, say scientists from the University of North Dakota. According to scientists, the excess cholesterol affect the blood-brain barrier, which is more permeable, so. The risk of dementia The blood-brain barrier - a filter between the blood and the central nervous system, the brain from toxins and microbes in the blood vessels protects caught. Scientists led by Jonathan Geiger led an experiment conducted. They fed rabbit food high in cholesterol. In addition, some of the animals received water containing 3 mg of caffeine (equivalent to a cup of coffee). As a result, after 12 weeks in rabbits treated with caffeine, the blood-brain barrier much faster than their counterparts who had consumed pure water, said Geiger. The researchers performed a histological examination of the brain of rabbits, the increased activity of astrocytes showed - brain microglial cells and decreased permeability of the blood-brain barrier. Scientists believe that it will help in the fight against Alzheimer's disease, for which there is an increase in blood cholesterol levels and thus the destruction of the blood-brain barrier, the scientists believe.
