Large swathes of the US now have an ALDI supermarket where you can buy genuine German schwarzbrot. Much tastier than psyllium husk in orange juice, although fans of white bread will find it a bit chewy at the beginning.
Come to Denmark, we have 100's of different kinds of rye bread that is significantly better than schwarzbrot. Or just make it yourself, it's not difficult.
We have "smørrebrød" which is quite delicious, and there is something for everyone. One particular famous smørrebrøds restaurant has a list of over 200 different kinds to choose from.
