The article (and the related book[1], written by a linguist) introduce the term to refer to cultural rules around what foods to combine, either at the same time or sequentially.
Eating habits is a very general term. The first 3 google results I got[2][3][4] aren't really related to what the article refers to as food grammar. I'd say referring to habit stresses the individual preference, while referring to a grammar stresses the cultural preference.
I'll say that if the Google results for grammar inside the book are exhaustive, the concept isn't fully developed though. I'd have expected a longer, systematic list of food-grammatical rules.
