i s more coffee drinking injurious to health ?

I like both, but I like coffee more. My favorite is French vanilla coffee. I drink coffee every morning. As far stimulating power, I feel both are equally good. But many a times it depends on the mind set of the people. I know many people getting a headache if they dont have a cup of coffee. From the science point of view, it is proved that tea is better for health. Tea helps in reducing body cholesterol. On the flip side, coffee is slightly acidic and excess intake make cause acidity.
