Basically the only thing that would do it is by force, either by scarcity, or by transmitted allergens to kinds of meat.

Super common near me! Worst part is ppl will still eat red meat because it's all that is available other than refried beans from the 7/11. It's scary what hunger will push people towards but even ppl with celiac disease will often be put in positions where it's starve or eat the fucken wheat.
