People who experience this trope may wish it was.
When you experience something of the highest possible standards, like eating Impossibly Delicious Food, the amount of happiness you feel is immeasurable. There are no pleasures in the world that could possibly compare to what you're feeling in that moment. Unfortunately, this tends to have the side effect of making everything else incredibly disappointing in comparison, often resulting in the inability to enjoy the things in life that you were once accustomed to. In the worst cases, those who go through this may end up going insane or committing suicide, either out of despair or due to being done with life.

- Dragon Ball: Cell has the word "Perfection" as his motto. Being an amalgamation of many of the strongest fighters in the series by their DNA, Cell aspires and boasts to be the strongest fighter in the galaxy. Having the DNA of Vegeta and Frieza explains his arrogance. To further the point, his last words before being obliterated are "THIS CAN'T BE!! I AM PERFECTION!!!"
- Food Wars!: This seems to be the case for those who have the God Tongue in the Nakiri family in regards to food. At the start of the series we see that Erina Nakiri's palate won't accept anything less than a dish she deems as "perfect" by her high standards, to the point she'll always find the exact flaws in any dish with a single taste. It's also combined with Blessed with Suck given that it'll eventually cause those who possess it to be unable to enjoy food at all due to a Sensory Overload disorder that comes with it, like it happened to Erina's mother Mana.
- Invoked in Inside Out when Disgust is charged with coming up with Riley's school outfit.
Disgust: When I'm through, Riley's gonna look so good, all the other kids will look at their own outfits and barf.
- In The Spiderwick Chronicles, people who've tasted faerie fruit have to live off it for the rest of their lives, because human food tastes utterly revolting in comparison.
- The fruit in Rossetti's "Goblin Market" seems to be an example as well.
- Isaac Asimov's George and Azazel stories include one of a man who wished for his ex to sing perfectly for one night. The narrator claims that the woman herself never sang afterwards, but for the audience, they had it far worse. He, himself, cannot listen to any music now, and as for the guy whose idea it was, he has to walk around with earplugs.
- In a Diary of a Wimpy Kid book, Greg used to swim at the pool in the country club and it was so fancy that when he got kicked out, he found it hard to "go back to being an ordinary Joe at the local pool".
- The Lemony Narrator describes this effect in The Last Battle, in regards to the fruit in Aslan's country. Unlike most examples of this trope, though, the characters eating it never have to return to their own worlds and eat normal food (having died and gone to heaven) so the negative parts of the trope are avoided.
- Downplayed in How I Met Your Mother Marshal once ate the perfect burger and claims all others taste like his grandpa's feet; however, he is shown being able to eat all other foods without any issues.
- Comprises an entire episode of The Adventures of Pete & Pete, as the underwear inspector Young Pete befriended is such a perfectionist that everyone else in the neighborhood attempts to live up to his high standards. It's only broken when he eats barbecue chicken so cleanly that he doesn't need a wet-nap - as that apparently defeats the entire point of eating barbecue chicken.
- An episode of Corner Gas has several characters getting "bumped up to a new X bracket" on various foods, having tried a higher quality version than what they're used to and finding themselves unable to go back. They view this as a bad thing, since the higher quality version is also much more expensive (for example, Oscar and Emma get bumped up from a $7 bottle of wine to an $18 bottle of wine, over double the cost).
- In Dungeons & Dragons, if a native of the Material Plane visits the Feywild and eats or drinks anything there, there is a risk that for the rest of that mortal's life, all mundane food and drink will taste like ash or dust to them, potentially even causing them to starve to death.
- In Warhammer 40,000 this is one of the ways that the Chaos God(dess) Slaanesh can cause people to fall to Chaos— in particular, Space Marine Primarch Fulgrim of the Emperor's Children.
- Changeling: The Lost: The Glutton was once a chef who was abducted by Crumbcoat and Ganache, a pair of cooking-obsessed True Fae. After he escaped from Arcadia, he found that food in the mortal world was completely tasteless to him. Eventually he moved into the Hedge full-time, subsisting on what he could harvest from there, the closest he could get to Arcadian food.
- Speedruns in general invoke this trope. Many speedrunners will practice for incredibly long times on a certain game (or even just a certain section of a game) trying to complete it as fast as possible. The livestreams take it Up to Eleven where the speedrunner will restart the entire game when they make even one mistake, and in some cases scream in anger and possibly Rage Quit entirely.
- In The Sims 4's "Get Famous" expansion, a Celebrity Sim who has eaten a lot of Excellent-quality meals will obtain the "Refined Palate" quirk, preventing them from enjoying any meal that's of Poor or even Normal quality.
- This is the reason that knots of rosary cord are so difficult to find in the Catholicism-inspired theocratic setting of Blasphemous. One character from the lore was so skilled at making rosaries that the church officially decreed her rosaries to be the only ones worth using, and ordered all others destroyed. Since she's long dead, there aren't any new ones getting made.
- The SCP Foundation gives us SCP-294, a coffee machine that can dispense any type of liquid in existence. When someone uses it to order "the perfect drink" and consumes the resulting liquid, they committed suicide soon after, leaving behind a note saying, "I'm sorry, but at this point, everything's just one big letdown."
- In the first major I'm a Marvel... and I'm a DC story arc, "After Hours", when Lex Luthor believes he's won, he muses that he'll never be able to top this and any further victories will be akin to "eating garbage". It sets Superman up to quote, "That's funny... I've never seen garbage eat garbage before." as he gets up and breaks his hand, so, never came to it.
- In Sword Art Online Abridged when Supreme Chef Asuna prepares a meal using an S-class ingredient Kirito brings her, the result is so impossibly delicious that both Kirito and Asuna think normal food tastes like garbage in comparison afterwards, and Kirito screams in dismay that they "Flowers for Algernon'd [their] taste buds".
- In the Rick and Morty episode "Morty's Mind Blowers", Morty has a euphoric reaction after stepping on a floor that Rick has made truly, perfectly level. However, as soon as he steps off:
Morty: Oh... everything is crooked! Reality is poison! I wanna go back, I hate this! Can't live like this, I can't live like this... LAMBS TO THE COSMIC SLAUGHTER!!!
- One Treehouse of Horror episode of The Simpsons has Homer accidentally cut off his own finger, which lands on his barbecue grill. Out of curiosity, he eats it, and finds it's the best food he's ever had - to the point he can't bring himself to eat anything except his own flesh.
