I don't see why not? It just has to be more specific -- chicken breast requires processing, but one is pretty much like another, unlike say, some morning cereal

I don't see why not? It just has to be more specific -- chicken breast requires processing, but one is pretty much like another, unlike say, some morning cereal from TV ads. Actually that might be a good heuristic, I don't remember the last time I bought food that even has ads. The store itself does have some ads that feature some of the items, I guess.
