The goal of the project is to study coffee addiction its causes and effect of coffee withdrawl in 3
persons.
Coffee is a brewed drink prepaired from roasted seeds, commonly called coffee beans, of the coffee
plant. They are seeds of coffee cherries that grows on trees in over 70 countries , cultivated primarily
in Latin America, Southeast Asia and Africa. Green unroasted coffee is one of the most traded
agricultural commodities in the worlds. Due to its caffeine content , coffee often has a stimulating
effect on humans.
Today coffee is the third most popular drink in the world , behind water and tea. Some controversy is
associated with coffee cultivation and its impact on the environment. Many studies have examined
the relationship between coffee consumption and certain , medical conditions ; whether the overall
effects of coffee are ultimately positive or negative has been widely disputed. The method of
brewing coffee has been found to be important to its health effects.

7. CONCLUSION
Though the effect of coffee or caffeine on your body is debated many
agree for it being positive while many agree for it being negative. The
most accurate statement at such a debate will be using it in a
controlled way can be useful rather harmful. As it well said
Conscience keeps more people awake than coffee.
