A seeming-human character who is extraterrestrial, supernatural or otherworldly (or just has very strange eating habits) may not eat the same things as ordinary humans. Aside from their Alien Lunch, they may be unable to eat or be repulsed by human foods. In other cases, they can and will eat human food, but the fact that they don't need to (or may need to chow down on something else as well) proves to be important.
May act as a Red Right Hand that reveals that the character isn't what they seem.
- In Dragon Ball Z Piccolo and Namekians in general only consume water because they're photosynthetic. That's right, Piccolo is a plant. Although before that revelation, Piccolo has been shown eating other things, mainly fish. The general consensus is that they only need water and sunlight, but are capable of eating. It may have to do with Kami (and therefore Piccolo) being from before the disaster that wiped out all Namekians except Guru, whose children may have been altered - much as King Piccolo's demon sons did not look like regular Namekians. Another factor could be that Namek has three suns, while Earth only has one.
- Sailor Moon's Eiru and An, Sibling alien lover... thingies. Really only brought forth in the two episodes where they're directly confronted with Earth food, and none of the cast members catch on to it (even when An flat out says that she doesn't eat food, though she catches herself).
- The metabolism of the Seven Lucky Gods (and their people) in Ranma Ĺ: Big Trouble in Nekonron, China can only handle rice and pickled vegetables. When trying an alternative meal, Kirin actually collapsed in agony and cried out for "P-P-P-PICKLEEEES!" Then again, said alternative meal was prepared by Akane, so...
- In Urusei Yatsura, the Oni can eat most human foods and even produce equivalents of their native dishes by inhuman amounts of spice, but some earth cuisine is beyond their capacity to handle. Umeboshi, which are basically pickled sour plums, get them totally plastered (humans, meanwhile, traditionally use them as a hangover and overindulgence remedy), though sake can cure them from being drunk, and they find the scent of garlic so strong and nauseatingly overpowering it has the same effect on them as tear gas.
- In Inuyasha, Sesshomaru references this to Rin after she brings him a meal to thank him for saving her life after they met. He literally tells her that he doesn't eat human food and simply wonders why she she just keeps smiling at him.
- In Cardcaptor Sakura, neither Kero nor Yue, being magical guardians, actually need to eat at all. Kero mooches food off of Sakura during the course of the entire anime and manga series solely for his own amusement.
- Inverted, of course, with Yukito, Yue's Sleep-Mode Size, who uses caloric energy to supplement any insufficient magic energy source.
- In the CLAMP series Wish Kohaku, being an angel, is nauseated by any food that's ever been alive, including plants (though she can eat honey); she gets her nutrition by bathing in sunlight.
- In Yokohama Kaidashi Kikou Alpha, a Ridiculously Human Robot, is absolutely fine with any plant based food (which she does indeed eat, despite being a robot), and actually can drink wine, but is lactose intolerant. It is heavily implied that any animal protein gives her (and, probably, other robots) a severe indigestion.
- An odd example in Hellsing comes from Seras tries to remain human by refusing to drink blood and trying to eat human food. The problem comes from the fact that, being dead, she can not only not process human food, but trying to eat it is outright painful; she can't even swallow it without immense effort.
- Alucard on the other hand, is seen enjoying a bottle of wine more than once. On an airplane. In broad daylight. Over the Pacific Ocean. He's just so powerful that the weaknesses suffered by other vampires tend not to apply.
- Inverted in Ergo Proxy where a mysterious man living all alone in a castle drinks nothing but wine, to excess beyond belief; it makes him just as creepy as someone who doesn't eat or drink.
- Al from Fullmetal Alchemist is a disembodied soul bound to a suit of armor, meaning he can't eat or drink anything. To people who don't know that there's nobody inside the armor, this can be a tip-off that Al's not what he seems (as if the freaking armor itself isn't enough of a tip-off).
- He's in training! You know, for his Alchemy.
- In Tokyo Ghoul, Ghouls are not only unable to digest any human foods save for Coffee, but find the taste so repulsive that it tends to make them throw up in response. Those choosing to pass as humans practice tricks to swallow enough to look like they're actually having a meal, but this requires that they throw it up shortly afterwards to avoid getting sick. When Kaneki becomes a Half-Human Hybrid, his inability to eat human food is his first sign that something went horribly wrong during his surgery.
- The Vision averts this trope despite being a synthezoid (android with a human mind and soul inside). He once explained that he has learned to simulate eating and drinking so that he could better blend in with humanity.
- Universal's Dracula (1931) of course, as the Trope Namer. The exact line is "I never drink— wine." He breaks his word about wine in House of Frankenstein, however.
- Dracula's Daughter also never drinks wine, giving the same line. But tea is no problem.
- Subverted in Dracula: Dead and Loving It. "I never drink... wine... oh, what the hell. Let me try it." (As it turns out, he's asleep and having a "day-mare".)
- Dracula 2000 uses a variant when Lucy offers Dracula coffee: "I don't drink... coffee."
- Love at First Bite includes this line, which adds "...and I do not smoke shit."
- Played with in the Underworld movies - after Michael is turned he tries to satisfy his craving for blood by eating a rare steak. He has no problem getting it down, but it doesn't quench his hunger at all.
- Bram Stoker's Dracula uses the line verbatim in a shout out to Lugosi's performance.
- In Henry Sellick's Coraline, the Other Mother cooks fantastically delicious meals, but we never see a speck of it on her plate. We find out later that she eats...other things...
- Angels in Dogma are unable to drink alcohol, after a pair of them got drunk and flipped off God. The Metatronnote is seen getting around this rule by taking sips of alcohol and spitting it back into another glass. It's not drinking if he doesn't swallow.
- In Ed Wood, Criswell gets Bela Lugosi to say it during dinner by asking him if he'll have a glass of wine.
- In Van Helsing, this gets playfully toyed with, when Anna sees one of the Brides sitting over a corpse, holding a wineglass full of his blood.
Aleera: Thirty years old. Perfectly aged.
- In Under the Skin, the alien (Scarlett Johansson) tried to eat chocolate cake but spits it out immediately. But according to the book, the alien's preferred diet is human.
- Nightfall Series: Averted. Vampires are not only able to drink wine, but do so a lot. Especially the Wicked Cultured Magnificent Bastard Prince Vladimir is always seen with A Glass of Chianti in his hand.
- In Anathem by Neal Stephenson, there's a character who doesn't eat ordinary food; this is eventually revealed to be a sign that he's from a universe where the laws of physics are different (ours, to be precise).
- Mackenzie in Tales of MU points out repeatedly that she doesn't need to eat food, and at first is so out of the habit that it makes her ill. Several of the other characters don't need to eat food, though some do anyway (though a few, such as Puddy, stick to only their favorites).
Sally: Oh, ha ha. I'm perfectly fine with, sarcastic pause, "vine", thank you. What I shouldn't have drunk is sticky drinks with funny names made up by someone with no sense of humour.
- Variations on the line used many times throughout the novels but especially in Carpe Jugulum, where the vampires are encouraged to try wine by their forward-thinking father. Igor also says the line, though it turns out that it's just wine he doesn't drink. Scumble on the other hand...
- Also in Thud!, where Angua, a werewolf, needles Sally, a vampire, with a variation on this line while they're both drunk.
- In Unseen Academicals, one of the more Genre Savvy characters asks for clarification as whether Vetinari "does not drink wine" or "does not drink ... wine." Later we are treated to Vetinari offering his vampiric lady friend some ...wine. The ellipsis is his.
- In Monstrous Regiment, we find that Maladict doesn't drink...horse piss.
- Also in Carpe Jugulum is a group of anti-Emo Teen vampires who invert the trope, and do drink... ''vine'', all the time. Really. Well, a glass of port every so often. Once. A couple of sips of shandy, and most of us threw up, but Donald wears a corkscrew around his neck, and he sometimes has a real cork on it! Fine, so it's not inverted! You Never Respect Me, Vampire Dad!
- Chelsea Quinn Yarbro's Saint-Germain series of historical fantasy is otherwise excellent, with the painful exception of the vampire protagonist's stubborn insistence on repeating the title of this trope at least once in every book of the series.
- In The Prophecy of the Stones Elphorys munches his "sticky purple mass" while Elyador eats his rather mundane bread and turkey.
- In Bloodsucking Fiends, Jody takes a tentative sip of water as she tries to come to terms with being a vampire. She has to spit it back up immediately, as she literally can't swallow it.
- Amren in A Court of Thorns and Roses. It's never specified exactly what she is, aside from a member of The Fair Folk(like most of the main cast), or why she seems to have such a thing for hearts.
- While the famous line doesn't appear in the book Dracula, Jonathan Harker does notice that he never sees the Count drink or eat...food.. The line that does appear in the book is "I have dined already, and do not sup", meaning that he has already eaten an early evening meal, and does not eat late. However, Dracula does apparently keep a good wine cellar for guests, as Harker comments very favorably on the "... excellent bottle of Old Tokay" he is served with his first supper at Castle Dracula.
- Anita Blake actually invoked this. When a waiter asks Jean-Claude what he's having, he responds with this line, prompting a Spit Take from Anita.
- In Neverwhere, the sort-of-vampire Lamia, when offered food: "I do not eat... curry."
- In Stardust, Yvaine doesn't drink or eat anything. She just absorbs light and darkness from her surroundings.
- Silas from The Graveyard Book "consumed only one food, and it was not bananas."
- The vampires from Twilight. They can eat food, but they can't digest it and have to vomit it back up later.
- In Shai Agnon's fantastical short story The Lady and the Peddler, a Jewish peddler is seduced by a beautiful widow living alone in a mansion in the woods. She feeds him endlessly with delicious multi-course meals, but he never once sees her eat or drink. It is eventually revealed that the widow is a cannibal and has killed and eaten all of her previous husbands. In fact, her body has grown so accustomed to eating human flesh it can no longer digest regular food.
- Played to the letter in the Artemis Fowl series. Should a fairy drink spirits, basically any form of alcohol, with humans they lose a lot of their magic and are basically exiled.
- Eli from Let the Right One In declines when Oskar offers her/him some candy, and when Oskar asks, "Don't you eat candy?" answers, "I can't." (Book version only; in the movie version, Eli eats the candy to please Oskar, and then becomes violently ill.)
- Averted by Eric and the other Chee androids in Animorphs. While they don't need to eat, part of maintaining The Masquerade is looking as human as possible, which includes eating and drinking whatever the culture they're currently immersed in eats and drinks; ingested food is simply vaporized inside their body.
- The Dresden Files: In Death Masks Harry has a somewhat friendly beer with a Red Court vampire before their duel. Like most people, the vampire is pleasantly surprised by Mac's beer, and when Harry expresses surprise that he drinks anything besides blood, the vampire turns it around on him.
Ortega: All you need is the water, after all. Why drink beer?Harry: You ever taste the water in this town?
- Babylon 5
- The Minbari of literally cannot drink wine. Even a small amount of alcohol sends them into a homicidal rage. Other than that, food from most worlds is edible by most species. Minbari having an adverse reaction to alcohol is also mentioned by Marcus when he first meets Delenn and Lennier in a Down Below bar as a means of proving who he was. It is also brought up in a single line said by Lennier in response to a drink offered by Londo, who is not entirely trustworthy when it comes to drinks. In fact, in other scenes, during Sheridan and Delenn's dinner dates, you see them both drinking wine. Slightly Hand Waved in that Delenn is half human through Applied Phlebotinum at this point.
- The Pak'Ma'Ra fit this trope PERFECTLY, as they projectile vomit anything synthetic, or fish. The doctor learned this the hard way. Note that projectile vomiting is even more obnoxious than usual in the case of the carrion-eating Pak'ma'ra.
- Humans who eat mixed alien and human food can get sick. It only came up once, though. Given the different biologies (some species breathe methane), I don't think that's too unusual.
- Buffy the Vampire Slayer and Angel: Vampires only need to drink blood, but some enjoy eating human food and drinking alcohol. Angel clarifies in one episode that he'll gain no sustenance from human food.
- The Wraith of Stargate Atlantis can consume human food and drink, but they gain no sustenance from it. They do occasionally eat food for the pleasure of it, though. After all, just because it doesn't feed you doesn't mean it tastes bad. Todd the Wraith from Atlantis positively loves dropping lines Lampshading this on humans he meets.
John Sheppard: "Fruit bowl. Nice touch."Todd the Wraith: "I thought it would make our discussions a bit more... comfortable. I hope they prove as delicious as the farmers who grew them."
- In Stargate SG-1, Teal'c doesn't drink alcoholic beverages. It's unclear if it's a Teal'c thing or a Jaffa thing. He also shows an aversion to drinking milk in one episode, refusing a warm glass with the line "I prefer not to ingest bovine lactose at any temperature".
- Torchwood has Owen come back from the dead, but with absolutely no vital function; as a result, he can't digest food or drink. His attempt at drinking later results in him standing on his head to force it out the hard way.
- When Peter Tork auditioned for The Monkees, the producers offered him a cigarette; Tork's reply was, "I don't smoke...those." Guess what he did smoke.
- In Sapphire and Steel, when offered a cocktail at a fancy dinner party in Assignment 5, Steel says he doesn't drink. Sapphire, however, has a glass of champagne.
- Lois & Clark: Superman once tells Lois that he doesn't need to eat, but he likes to. Which is fairly evident since his pantry is stocked with almost nothing but junk food.
- Sanctuary's version of Nikola Tesla, being a vampire, is implied to be able to survive perfectly well on a synthetic blood substitute that Magnus developed to avoid his need for blood. However his is also a first class wine snob and since he can't get drunk he usually makes serious inroads on Magnus's wine cellar whenever he visits for any length of time.
- Odo in Star Trek: Deep Space Nine doesn't drink... Being a changeling, he has no taste buds, so it's not worth it to try eating or drinking. In social situations, he morphs part of his substance into a glass and fluid, which he then "drinks"; it helps him to fit in. As such, this is a literal statement applying to liquids in general, not just alcoholic ones:
Quark: What'll you have?
Odo: I don't drink.
Quark: A soft drink, then?
Odo: (more firmly) I don't drink.
- He mentions that he did try eating and drinking once. The end results were. . . not pleasant.
- In the Doctor Who story "The Evil of the Daleks," the Doctor questions Arthur Terrall about the fact that he's never seen eating or drinking, at least around others. It has something to do with the fact that he's mind-controlled. It's never made clear exactly what his lack of public eating signifies; it probably just shows how unsocial the mind-control is making him, and adds to his air of creepiness and wrongness.
- An inversion in A Vampyre Story: Mona, our heroine, is a vampire. This is established fact. But Mona is in hardcore denial that this is the case, and claims that she's under a curse. A curse that gives all the symptoms of being a vampire, without being a vampire. To maintain her delusion, she claims that what she drinks is wine (it helps that her captor gets the stuff himself, so she never actually sees where it comes from). By the time the game begins, this is already a very old argument between Mona and her buddy Froderick the bat, who sarcastically refers to it as a salty-tasting merlot with a slight iron aftertaste. She actually delivers variations on the line when presented with other beverages.
- If you talk to a peaceful vampire in NetHack, the message you get is "I only drink... potions."
- Inverted in Sid Meierís Alpha Centauri: The Datalinks inform us that humans do not eat... food from Planet's native life (without heavy processing). However, since Earth plants grow just fine in Planet — even better than in Earth — getting food is no problem.
- Given a nod in Conker's Bad Fur Day with Conker's vampire great-great-great grandfather.
- In Saya no Uta, Saya refuses to eat in front of Fuminori. It's because she's eating human flesh, and serving it to him, too.
- The same line spoken by Dracula is also used in Bloodrayne 2.
- In Dwarf Fortress, vampires do not eat food or drink booze like normal dwarves. This can be extremely helpful in identifying them. While they don't drink it, but they still suffer the effects of alcohol withdrawal.
- [Urist McVampire] needs alcohol to get through the working day, and can't even remember the last time he had some.
- Played straight in Vampire: The Masquerade - Bloodlines. In the Asylum club, the bartender will ask the player character what they want to drink, to which they respond "I don't drink... alcohol."
- Vampire: The Masquerade and Vampire: The Requiem:
- Both make it clear that the only thing vampires can digest properly is blood. Masquerade goes for a more instantaneous rejection; the vampire gags as the food turns to ash in his gullet, and must cough it back up violently (unless they've taken the "Eat Food" merit). Requiem actually allows vampires to partake of mortal food and drink, taste it, and store it... but not for long, as by the end of the night, they'll have to vomit it up in a bloody mess.
- The Macellarius clan in the latter game are descended from a vampiric glutton, who forced himself to devour food and drink well beyond what his body could stand (no longer being able to eat or drink infuriated him). Eventually it warped his blood enough that he and his children gained the ability to eat... human flesh. Their unique Discipline, Gustus, allows them to devour raw flesh and gain Vitae from it.
- In Warhammer 40,000, Eldrad Ulthran, famous Farseer of the Eldar craftworld of Ulthwe, appears to invoke this trope. When meeting with the primarch Fulgrim, he hosts a banquet and Fulgrim notes that Eldrad does not have any meat on his plate. When Fulgrim asks, "Does your kind not eat meat?", Eldrad replies simply "*I* do not eat meat."
- Rose from Clan of the Cats comments in her first appearance, "I never drink...beer."
- Addison Constance Loveworth from IronGate can't consume except blood, and she only drinks fresh bovine blood in a teacup taken from cows kept in stables on the property.
- Malack from The Order of the Stick does not turn up for meals with the rest of the group. When questioned about this, Tarquin replies that Malack has "a condition" which requires a very specific diet, so he eats his meals alone.
- Daniel is a vampire that can only drink blood. He states that anything else he tries to consume simply comes back up his throat.
- Gaia Online:
- Minigame Frontier Skies has a possible event in which Louie Von Helson gets a craving for cheeseburgers and depletes your food supply. Otherwise, he doesn't show any signs of understanding human cuisine. Or anything else about humans, really.
- Louie and his sisters competed in the Pie Hard pie-eating contest (the Twins lost early; Louie made it to the top six), and explained the situation with Gaian vampires and food: they can eat human-style fare, but it's just not as tasty to them. This also justifies an unused storyline that had Louie shilling a soy-based blood substitute.
