Why do people like caffeine?


Caffeine is amongst the most commonly used ingredients in the world which is found in tea, cacao plants and coffee. It is a natural stimulant that affects your brain and central nervous system to keep you alert and prevent tiredness.

Historians claim that people have been enjoying the effects of caffeine since 2737 B.C when the first tea was brewed and ever since then people have continued to enjoy caffeine in other forms such as coffee and caffeinated soft drinks.

Once consumed, caffeine is quickly absorbed into the bloodstream and makes its way to the liver where it is broken down into compounds after which it starts to affect our body.
