Rhetoric of food is very idiosyncratic and personal to the individual author. However food is what connects us to each other. Every human being likes and needs food. Regardless of the type of rhetoric an author uses in his or her writing, every one can relate to the writing because food ties us all together. Driven by what we eat and where we eat it, food rhetoric is often beautiful because of all the cultures involved. Whether you’re from Indonesia or South Africa, you enjoy eating food. Rhetoric of food is about unity, because it unifies all cultures, races, genders, and political views. Rhetoric of food is a tool or a vehicle. Food writing is used as a vehicle to share something personal (opinion piece), as a tool to promote activism (investigative pieces), or even as a tool to teach (recipe).
I completely agree that the rhetoric of food is personal to the author and their purpose for food writing. I also agree that it unifies cultures, especially through simple, staple foods that can be prepared in so many different ways based on the origin or ethnicity of the author.
