===Diet===
Vulcans are [[Vegetarianism|vegetarians]] by choice and were [[omnivore]]s in ages past.<ref>In the [[Star Trek: The Original Series|''Star Trek'' original series (''TOS'')]] episode "[[All Our Yesterdays (Star Trek: The Original Series)|All Our Yesterdays]]", Spock willingly consumes meat; partly as a result of the effects of time travel 5,000 years into the past.  Vulcans are repeatedly stated to be  [[Herbivore|herbivorous]] in the ''[[Star Trek: The Animated Series|TAS]]'' episode "[[The Slaver Weapon]]", by the carnivorous [[Kzin]]ti.</ref> It is a Vulcan custom for guests in the home to prepare meals for their hosts.<ref>''[[Star Trek: Enterprise]]'' episode: "Home"</ref>

Vulcans are said to not drink alcohol, though they are often depicted as doing so.<ref>''[[Star Trek: Voyager]]'' episode "[[Repression (Star Trek: Voyager)|Repression]]", humans and Vulcans are shown drinking a Vulcan alcoholic drink called "Vulcan [[Brandy]]". In the ''TOS'' episode "[[The Enterprise Incident]]", as part of his diversionary role during an espionage mission against the [[Romulan]]s, Spock shares a drink known as Romulan ale with the female Romulan commander. In a later ''TOS'' episode "[[Requiem for Methuselah]]", Spock specifically requests a [[Saurian]] brandy after [[Leonard McCoy|Dr. McCoy]], while serving himself and [[James T. Kirk|Captain Kirk]], observes that he had no expectation that Spock would be joining them in a drink for fear that the alcohol would affect his logic faculties. Spock claims that he wants a brandy because he is experiencing an unaccustomed envy for his host's artwork. In ''[[Star Trek: First Contact]]'', when the Vulcans first meet [[Zefram Cochrane]], Cochrane serves them alcoholic beverages, which they take in lieu of dancing.</ref>

In an episode of ''[[Star Trek: Deep Space Nine]]'', [[Quark (Star Trek)|Quark]] alludes to Vulcans becoming inebriated by ingesting [[chocolate]].<ref>[[The Maquis (Star Trek: Deep Space Nine)]] offers a Vulcan client some Vulcan Port or chocolate</ref> This is confirmed in the novelisation of [[Star Trek IV: The Voyage Home]]. Kirk buys some candy to get change for the bus. When he gives one to Spock, Spock asks if it contains sucrose. When Kirk asks why, Spock tells him that sucrose has the same effect on Vulcans as alcohol has on humans.

The first draft of an episode of ''[[Star Trek: Voyager]]'' mentions that Vulcan coffee is poisonous to humans.
