In short, we shouldn't drink anything at all.
There is what health tells us, and there is what we like. Very often, those are not very compatible. I personally like coffee a lot, but as a plain coffee. I know exaggerating is definitely not good for my health... but I like it, so, I only try not to exaggerate ;)
For the rest, it is at the end a matter of that there is no free lunch. There is always a price to pay and we need to live with it.
