Honestly, I enjoy the philosophical musings. Most isekai don't really look into the kind of influence you can spread in a new world with that kind of genre.
And, personally, I am so against the promotion of consumerism here by Shiro here.
The anthropology of food is a pretty cool topic though. There can be immense economic and political implications when a certain cultural food becomes popular. A modern example is sushi becoming popular in many other countries and how Norway made salmon sushi more accepted in order to sell their overabundance of salmon, which traditionally wasn't eaten raw in Japan.
