What was the first cereal?

While there were earlier forms of breakfast foods that could be considered precursors to cereal, Granula was the first to be marketed as a ready-to-eat, dry breakfast food.

Here's a bit more about Granula:

* Ingredients: It was made from unsifted graham flour baked into hard biscuits that had to be soaked overnight before consumption.

* Health Focus: Jackson promoted Granula as a healthy and wholesome alternative to the heavy, meat-based breakfasts of the time.

* Popularity: Despite its popularity, the process of preparing Granula was quite tedious, leading to the development of more convenient options later on.

While Granula might not be on supermarket shelves today, it paved the way for the cereal industry we know and love.
