Sincerely held secular beliefs are protected in many jurisdictions (and should be in all). Vegans have been fighting for this issue a lot, because it is an ethical principle, held as deeply, if not more, than most religions but not religious in nature (the less charitable way to put it is the ethics are based on reality instead of fictional stories. In a sensible world it would clearly receive more support from the legal system than religious beliefs…).

This seems a little different. This seems more about “enjoyment” as opposed to a sincerely held belief.

Some places also respect that. Famously, the Norwegian terrorist who killed 77 people demanded, and received, a PlayStation 3. And if this jurisdiction had similar laws as Norway they probably would have provided vegemite.
