I know it's non-paleo, but I am quite partial to coffee. I also see that Neanderthin recommends green tea, which I have started drinking occasionally instead. I have two questions: 1. Is green tea really paleo? Were people drinking it 100,000s of years ago? 2. Green tea does contain some caffeine, I believe. So is the objection to coffee (apart from it not being paleo) that it contains a lot more caffeine, or is there more to it? In other words, is it better to drink decaff coffee than caffeinated, or does coffee contain/do something else which is so bad that one should avoid it altogether? Thanks for any opinions. Jo
