Is it bad for your health? Most reports say no, and they all peg the 'healthy' intake anywhere from 4-5 cups a day (pregnant women should limit themselves to 2-3 cups). As long as you're below the limits, most of the reports encourage coffee drinking. Coffee lovers are 80% less likely to develop Parkinsons and 25% less apt to develop colon cancer. Some of the latest Parkinsons drugs are actually being developed from a derivative of the same caffeine in your average cup o'Joe.
