Caffeine, a natural stimulant, is commonly known to be used by several people to stay active and keep awake.
It is also generally tagged as bad and unhealthy, having numerous negative effects on the body.
We should however take note that this same caffeine also does as much good to our health.
Caffeine, as said earlier, is a natural stimulant that is commonly found in a variety of teas, cacao plants and also coffee. It stimulates the brain and central nervous system, causing one to stay focused/at alert and checks fatigue.
Upon consumption, it is absorbed from the gut into the bloodstream. It then goes to the liver and is decomposed into compounds that affect functions of various organs.
Caffeine’s target point is the brain. The brain is stimulated by blocking the effects of the neurotransmitter, adenosine (it relaxes the brain and causes you to feel tired).
Foods and drinks that contain caffeine include; energy drinks, coffee, espresso, soft drinks, cocoa beverages, brewed tea, chocolate milk, e.t.c. It is also found in some drugs like weight loss supplements.
