AskBwog: Trippin’ on Tryptophan
Bwog fell asleep at 8pm on Thanksgiving (and last night….oops), and was determined to find out why. Assuming those after-meal droopy eyes had something to do with science (the idea of a god of food comas was dismissed after much discussion), we set Bwogsleuth Zach Kagan on the trail. Here he presents a roundup of internet wisdom to reveal the cause of post-turkey sleep disorder.
It’s a familiar scene. You’re watching Thanksgiving day football, and your eyes start to droop. But it’s not just you—your whole family, aunts and cousins, that neighbor you only see three times a year—they’re all slouching in their chairs, lazily fighting the sweet embrace of sleep. Just then your Auntie Nora pipes up and says: “It’s the tryptophan! In the turkey!”
Ah! But you, seeker of truth, are just as much trapped in the cave as Auntie Nora, because the whole tryptophan in turkey causing drowsiness is but a myth. Pervasive myth at that: there’s even a Seinfeld episode where Jerry sedates his girlfriend with a big turkey dinner so he can play with her toys (it’s less creepy in context…well, on second thought it isn’t really). The truth is that that tryptophan is a mild sedative contained in turkey, but the story is a bit more complicated. It’s time to put your biochemistry caps on: tryptophan is an essential amino acid that you get from food. Your body needs it to make important stuff like boring ol’ vitamin B, but also fun neurotransmitters like serotonin and melatonin which calm you down and can make you drowsy. Case closed right? You eat lots of turkey, get ingest oodles of tryptophan, your brain goes into a serotonin producing overdrive, and you nod off to sleep halfway through Alcibiades’s speech.
If only it were that simple! There are a bunch of other amino acids in turkey as well, and tryptophan is one of the scarcer ones. Amino acids need to compete to get past the blood-brain barrier and on Thanksgiving there’s just too much competition and tryptophan gets drowned out. Really, the only way that tryptophan can make you drowsy is on an empty stomach, and how likely is that on turkey day? Turkey doesn’t even have a particularly high amount of tryptophan (both beef and soybeans contain more). So, what really makes you sleepy after Thanksgiving? The same thing that makes you sleepy after any meal.

Thanksgiving approaches quickly and many of you will be returning to your families. Bwog sympathizes with those of you who will be returning to dysfunction, disorder and other such unpleasantness. So in the spirit of the holiday, Bwog presents a list of three great Thanksgiving movies – two of which feature a pre-Tom Cruise insanity Katie Holmes. Oh, the good old days.
Bwog Lecture Hopper David Berke attended
The train from the airport emerges into open air, weaves through tired concrete apartment blocks painted in worn pastels, occasionally grants glimpses between them of an endless, rolling cityscape of similarly dilapidated structures, all suffused in a dull green-blue haze. It halts at a transfer point shrouded in fog and you exit, your face sprinkled with forty-degree rain. That’s when you remember: despite the minarets puncturing the distant horizon, the hijabs, the buzz-buzz-buzz of calls to prayer mediated by electric megaphone, Istanbul is far closer to Bulgaria than Bahrain.
one Orientalist trope after another was swept away by Atatürk’s steady – some would say overzealous – Westernizing hand. Some dissenters, naturally, have chosen to paint the city one way or another, instead. “This Istanbul is European thing is bullshit,” one grad student told me before my departure. “Most of it is just like Damascus.” In Orhan Pamuk’s Snow, on the other hand, distant Istanbul comes off no less foreign, no less “Western” to ur-Turkish Anatolia as Paris or London.
“Hey, what kind of bird is that?”
