You still need this stuff while people's diets change, though - diets generally have a good amount of cultural, religious, and family ties and it takes time. Then there is the entire issue of trying to change the diets of poor people at a time when places (like the US) aren't even making sure the folks at the bottom can get enough calories and nutrients nor are we making sure diabetics and others have a diet fit for them, let alone trying to make sure folks aren't eating badly for their teeth. And I'm sure I'm not considering things like changing the crops being planted and things like that. But we have this stuff, perhaps. It isn't moronic considering we probably aren't going to change diets suddenly.
