Jesshosy's Notes

I think enjoying my 1 cup of coffee or tea everyday is one of the most pleasurable moments of the day (I limit myself to only 1 cup a day). However, having heard of medical experts encouraging us to have less coffee and tea due to it’s’ caffeine nature, I think the below caffeine information can guide us in selecting the best type of caffeinated beverage.

Caffeine is found in varying quantities in beans, leaves, and fruits where it acts as a natural pesticide. It is commonly found in coffee plant and leaves of the tea bush. Caffeine in human act as a central nervous system (CNS) stimulant, used to temporarily ward off drowsiness as well as restoring alertness.
