This should be a rhetorical question...

[The Might]

I think that due to the special link between their bodies and their souls they were not so easily ifluenced by such pleasures such as food, drink, or..,you know what I mean

They are not easily deceived by their own kind; and their spirits being masters of their bodies, they are seldom swayed by the desires of the body only, but are by nature continent and steadfast. ~ Laws and Customs of the Eldar, Morgoth's Ring

Still, this comes a little bit in conflict with the image of Elves drinking Dorwinion wine in the Hobbit

Considering however why and how Tolkien wrote the Hobbit and the Laws and Customs of the Eldar, I am inclined to think that such abuses were only possible among more uneducated Silvan Elves, and that Noldor, Vanyar, Falmari or Sindar would have never done something like this. Still, I doubt that Thranduil's folk did that on a daily basis, and so it might have been a single case.

So no, no fast food Elves I'm afraid
