The word "cereal" has been employed in literature with a remarkable range of meanings. In some contexts, such as in etiquette manuals by Emily Post, it straightforwardly denotes a common food item served at breakfast, as in the description of its placement alongside toast and eggs [1, 2, 3]. Meanwhile, culinary texts like Apicius’s recipe illustrate cereal as an ingredient absorbed into cooking practices, where it is soaked and boiled with legumes [4]. Additionally, works by William H. Ukers expand the term’s scope to include not only the grain itself but also its role in commercial and substitution contexts—ranging from manufactured cereal packages to its use in coffee substitutes [5, 6, 7, 8, 9]. Finally, in anthropological studies by James George Frazer, cereal transcends its utilitarian role and is even sanctified as a divine force, invoking the imagery of a cereal deity who is venerated by believers [10, 11].
