Ah, the Thanksgiving post-meal nap. Is there anything more glorious?
Of course, we can all blame that pesky chemical tryptophan in the turkey for our comatose states ... right?
It turns out tryptophan might be a bit of a holiday scapegoat left over from the 1980s, when tryptophan was sold as a popular sleep aid, according to LiveScience.
The belief in tryptophan's soporific powers is widespread.
For Thanksgiving Day, 2014, Google even featured the question on its homepage. "Ok Google, what is tryptophan?"
"Tryptophan is one of the essential amino acids. Essential, because people have to get it from their food." "The body uses tryptophan to make seratonin, a brain chemical that promotes feelings of well-being and relaxation." (Video via YouTube / BitesizeScience)
Turkey does contain tryptophan, but here's a Thanksgiving bomb drop: turkey has no more tryptophanthan pork or chicken! And the list of everyday foods that contain tryptophan?
Chocolate, milk, cheese, bananas, peanuts, oats, pumpkin and sunflower seeds ... it's exhaustive, and exhausting.

So enjoy that Thanksgiving dinner to its fullest. Just remember that it's likely the sides, not the size of your turkey serving, that are putting you to sleep afterward.
