title_body: How does Caffeine-free coffee affect your body?
upvoted_answer: I personally couldn't taste any difference between decaf and regular coffee but depends on the brand. According to some resources is decaf the biggest source of antioxidants in the western diet and it has positive impact on health if you drink 2-3 cups per day. From my personal experience, you can drink probably as much decaf as you want since it doesn't have any negative side effects, regarding regular coffee you might get breath problems and high blood pressure if you drink too much. There are lot of good brands of decaf where you don't taste any difference between it and regular coffee.
