Coffee knowledge men often drink coffee to relieve mental decline

New research shows that drinking coffee can keep the brain healthy. Men who drink three cups of coffee a day have the least mental decline in old age, a decade-long study has found.

Researchers at the National Institute of Public Health and Environment in the Netherlands analyzed the mental decline of some older men over the course of a decade.

676 men from many European countries took part in the test to test the effect of coffee on cognitive ability. Men who don't drink coffee at all are four times more intelligent than those who drink three cups a day. One theory that explains this is that caffeine may boost memory by having an effect on the brain's receptors. High blood pressure patients have coffee in their prescriptions. The National Institutes of Health is testing whether drinking two cups of coffee a day can help lower blood pressure.

Doctors say coffee has a certain effect on patients with high blood pressure, causing their pancreas to secrete a certain amount of insulin. Insulin is very helpful in controlling blood sugar levels. Although exactly how coffee works is unclear, scientific research has shown that coffee contains flavanols, which are good for the blood circulatory system and improve insulin sensitivity.
