Earlier quoted context omitted.
Taco Bell doesn’t use butter, AFAIK.
Neither do many major cuisines, like Mediterranean, Mexican, Thai, Japanese and Chinese. Is butter really the problem here? Because to me it sounds like the problem is habitual over-eating.
Japanese izakayas frequently sell grilled items wrapped in foil that is swimming in butter. Again, I assume you will reply: "Oh, but that's not traditional Japanese cooking -- it doesn't count." Again, most normie readers don't care about that distinction.
