I'm aware of the food. My sister is a devotee of it. Perhaps I should have been more clear. I don't consider Nutella as a personal name a problem because of the brand name, or at least, enough of a problem to justify banning its use, in
France or anywhere else. I consider the slang meanings of "nut" and "nutty" to be far more problematic, but this would apply only in English-speaking countries.
