At least with chocolate, during communist times in Poland AFAIK if someone was packaged as "chocolate" it had to be chocolate - it was "chocolate-like product" that you had to be wary of which was closer to american "chocolate"[1]

[1] I jest, I jest, but what is legal to be in store-bought chocolate in USA, based on things I actually ended up getting while visiting, was literally one of the ways communist poland cut chocolate to make "chocolate-like product" :V
