-->--'''''Series/LawAndOrderSVU''''', "Juvenile"

Alice and Bob are sitting down at a restaurant to eat. Alice orders spaghetti. Then Bob, who is a doctor, starts talking about how he operated on a patient with flatworms today, and describes in graphic detail how he pulled out the long, thin, white, worms from the patient's intestines...

...And on second thought, Alice decides she'll have a salad instead.

This trope is when a character had planned to eat a certain food, but changes their mind based on a conversation or experience that causes them to make a mental association between it and something nasty. The character doesn't [[LostMyAppetite lose their appetite]] ''entirely'', they just can no longer stand the thought of eating that ''particular'' thing.

It does happen in Real Life.

* ''TourOfTheMerrimack'': In ''The Myriad'', Captain Farragut describes over dinner how gorgons melt into caustic brown slime when they die, then tells his chef to skip the French onion soup.
* ''{{Slayers}}'': In the light novel ''The Battle of Saillune'', Lina and Gourry are attacked by a number of lesser demons that possessed items of food, including a nasty tentacle monster that emerges from their squid stew. After the fight, they order more food, and Gourry requests they skip the squid stew -- though Lina disagrees, saying it'll take more than that to make her lose her appetite.
* ''Literature/{{Animorphs}}'': In ''The Android'', Marco's parents try to serve him chicken for dinner after he was nearly killed by a bird while in spider morph. Marco opts out.
* During the dinner at ''Literature/TheRestaurantAtTheEndOfTheUniverse'', Arthur initially orders a steak, changes to a salad when he finds out what the steak comes from, and eventually settles for a glass of water.
* Happens to Jessie and Cooper in ''[[Literature/{{Spellbent}} Shotgun Sorceress]]'' when they discover that, as a side-effect of some necromantic magic they performed, they can feel the death of each item of food they taste. They regretfully pass up the rib-eye steak in favor of a salad.
* ''Literature/TheCanterburyTales'' has an example in the description of The Cook in the prologue. While the Cook is a SupremeChef, Chaucer unfortunately can't enjoy a dish of his because its appearance reminds him too much of a nasty running sore the Cook has on his leg.
* During ''Literature/DrFranklinsIsland'', Semi "chooses" to become a fish, Miranda "chooses" to become a bird. They're locked in a small suite and delivered meals while they wait for [[InvoluntaryTransformation the changes]] to start, and Semi starts refusing seafood, but Miranda still eats chicken. [[spoiler: Appropriately, Semi becomes a manta ray-like creature which eats only plankton, and Miranda becomes an ambiguous hooked-beak bird which is repeatedly compared to a BigBadassBirdOfPrey.]]
