Okay, leaving aside for the moment that 'seflie' is itself an abomination of a term, and yet another sign of the degeneracy of modern society, the thing that really annoys me even more about it is misuse of the term.
A 'selfie' is a photograph that you take of yourself - either directly, or in a mirror. Other people and other things can appear in a selfie, but those two rules apply - you must appear in the photo, and you must take the photo yourself. (I'm sure there's a clue there in the name, but I'm not entirely sure what it is...)
If someone else takes a photo of you, that is not a selfie - that is a photograph. I know it's a shocking concept, but there it is. Likewise, the only way to get a "food selfie" is if you're a cannibal and your food is really underdone. Otherwise, it's just you taking a photo of your food - which may or may not be an horrible and pretentious habit, but it's not a selfie.
