The answer may surprise you – decaf coffee actually contains caffeine. The decaffeination process removes 97% of the caffeine from the coffee beans, leaving a small amount of caffeine behind. However, the amount of caffeine in decaf coffee is so low that it is considered safe for most people to drink. So, if you are looking for a way to cut down on your caffeine intake, decaf coffee is a good option. Just be sure to check the label to make sure that it truly is decaffeinated.
