Although more studies are needed, recent research shows that drinking coffee could lower the risk of liver and colon cancer, type two diabetes, and even Parkinson's disease. Futhermore, recent long-term studies of women showed that those who drank several cups a day were less likely to develop high blood pressure than those who drank less or none at all.
Other studies has shown that the rich source of "disease-fighting" antioxidants in coffee may reduce cavities, boost athletic performance, improve moods, and stop headaches -- not to mention reduce the risk of gall stones and cirrhosis of the liver (decafe). Researchers warn against extra calories that comes when you start adding milk, cream, sugar and caramel, however.
For the most part, you can expect more than from a cup of coffee. Just keep your intake to a minimum, cut back on the extra addatives, and enjoy a cup (or two - three) of black coffee - no sugar, no cream each morning.
Hope this answers your question!

Doctor: I am, bit by bit.
