Decaf still has enough caffeine left in it that it affects me. So interesting how differently bodies react to different amounts. I can't even have some kinds of chocolate.
Depends on the brand. The modern Swiss Water process (which is what most high-end espresso brands use nowadays, since it's cheaper and doesn't rely on chemicals) uses osmosis to remove 99.9% of the caffeine from the coffee bean.
Wow. That's extreme. Decaf supposedly has way less than 1/20 of the caffeine of regular coffee. Maybe you are sensitive to other substances that coffee contains on top of your sensitivity to caffeine?
Things we ingest have many weird organic substances which we don't pay much attention to because they don't noticeably harm nearly all people. But there's no guarantee they will not somewhat harm anybody.
Nothing we eat or drink was perfectly designed for human consumption. We just kind of get away with it.
