When companies have engineers sitting around figuring out the precise amounts of salt, sugar, and crunch required to force a person to eat 4 servings of something in one sitting… yeah, at least put a warning label on it. I don’t know that I agree with outright bans or anything, but people should be properly warned about the risks.
As another commenter pointed out, those are hyperpalatable foods, not 'ultraprocessed foods'.
Besides, 'ultraprocessed food' itself is and has always been a useless buzzword (buzzphrase?).
