Drinking coffee can effectively prevent Alzheimer's disease.
Drinking a cup of coffee a day can effectively prevent Alzheimer's disease, according to research published on the 3rd in the United States.
Researchers at the University of North Dakota School of Medicine and Health have found that caffeine in coffee blocks the damaging effects of high cholesterol on brain nerves. The rabbits were given 3 milligrams of caffeine a day-the equivalent of a cup of coffee a day for an average-sized person. During this period, rabbits also ate cholesterol-rich foods daily. After 12 weeks, laboratory tests showed that the blood-brain barrier was denser in the rabbits that consumed caffeine daily.
The blood-brain barrier can block certain substances from reaching the brain nervous system through blood circulation, and high cholesterol can destroy the blood-brain barrier, causing brain nerve damage such as Alzheimer's disease.
