seems like responses here were assuming you meant the french press somehow had chemicals, but you're saying that the coffee beans have substances that maybe a filtration system removing from the coffee makes it better? Can you source that, because people have been drinking coffee a long time and I don't think that's a concern. After all, coffee is a plant material harvested then burned grinded up and suspended in water. Like most plants it probably contains substances, which in great quantities could kill humans, but if it were toxic we'd know by now. Plus the fact that you can buy chocolate covered espresso beans, where you consume the bean entirely. That would surely be the most toxic no? Never seen a warning on those.
No, it's Cafestol, which unlike dietary cholesterol does substantially increase serum cholesterol. Whether it's the harmful kind (LDL pattern B), I've been unable to figure out.
