My first reaction, being an ardent lover of many ethnic cuisines, was "of course I'd never use something like that" but then I got to this line:
Eating to me is a leisure activity, like going to the movies, but I don't want to go to the movies three times a day.
Suddenly, I'm imagining "A DVR for eating." You have a steady intake of Soylent (the name absolutely must change), and when you have time to prepare a nice meal or go out to a restaurant, you adjust your intake ahead of time so your hunger level is appropriate. Crazy, but now I have another ingredient for my sci-fi universe.
