Forbes published an article about the health benefits of coffee.
Let’s get right to the good news: drinking coffee seems to reduce your risk of death from oral or pharyngeal cancer by about 50%. Drinking more coffee is better than drinking less, and drinking caffeinated (normal) coffee is better than decaf.
We don't have to feel guilty to have another cup of coffee! It's good for you. Also the article says...
Perhaps the most encouraging finding is this: in people who have been nonsmokers for at least 20 years, 1-2 cups of coffee per day corresponds to a 32% decrease in the risk of death from throat cancer. More than 2 cups per day corresponds to a 64% decrease. And among all participants (including former smokers), more than 4 cups a day seemed to provide the greatest benefit.
