Effects of caffeine on human body.

Black coffee is the most popular drink in the world. Its flavor and aromatic properties make it a unique food material. There are two opposing views on the effects of coffee on the human body. Some people believe that coffee too disturbs the nervous system, corrupts dental health, and no longer has any effect on health. Others believe that caffeine has unique helpful microelements that the human body cannot obtain from other foods. So what does caffeine have to do with human health?

Sources of caffeine

Coffee drinks have tonic properties, and fresh coffee beans contain trace elements that are irreplaceable physiological value for humans. Not many people are aware of the fact that a substance called caffeine is not only found in coffee beans. There are three other sources of caffeine, such as cocoa beans, cola fruit, and Chinese tea.

People with a strong nervous system need more caffeine to stay awake after a sleepless night.
People who consume moderate amounts of coffee and tea regularly have increased cerebral cortex activity.
