Coffee is one of the world's top three drinks.
Coffee, tea and cocoa are the three major drinks in the world today. Coffee contains caffeine, polyphenols, aromatic oils, resins and other ingredients. Among them, caffeine can excite brain nerves. This is the reason why drinking coffee has a "refreshing" effect.
Recently, according to foreign medical journals, drinking coffee can also prevent Parkinson's disease (a degenerative brain neuropathy). A large-scale survey conducted by an European medical organization over the years shows that people who drink 3-4 cups of coffee a day are 90% less likely to develop Parkinson's disease after the age of 65 than those who never drink coffee. So why does drinking coffee prevent Parkinson's disease in old age? Western medical researchers speculate that both caffeine and flavonoid polyphenols in coffee can pass through the blood-brain barrier and act on brain tissue. It is likely that the synergistic effect of these substances plays a key role in the prevention of cerebral neurodegeneration.
European medical researchers also pointed out that drinking coffee not only has this pharmacological effect, but also has the effect of preventing Parkinson's disease. Because green tea also contains a certain amount of caffeine (so tea is also refreshing) and polyphenols such as catechins. Therefore, whether drinking coffee or green tea has a certain health effect on the brain.

Women drinking more coffee can effectively reduce the risk of stroke.
American scholars analyzed the data of 83076 women (with an average age of 56 years) in the nurse health study. The results showed that from 1980 to 2004, there were 2280 cases of stroke. After adjusting for several stroke risk factors, the researchers found that drinking caffeinated coffee was significantly negatively associated with stroke risk. Compared with those who drank less than 1 cup of coffee per month, those who drank 2 or 3 cups of coffee per day died.
