Have you heard the news? Turkey is not to blame for the post-meal Thanksgiving naps. It’s been well-known for years that turkey contains tryptophan. Tryptophan is a precursor of serotonin, the neurotransmitter than regulates sleep.
However, tryptophan makes up 1% of the protein in turkey. One percent is the typical content of meat and actually half the tryptophan content of milk (2.34%).
Instead of turkey being at the root of Thanksgiving Dad sleepiness, it’s the carbohydrates in all those side dishes – stuffing, mashed potatoes, etc. The extra carbohydrates boost insulin production. It’s speculated that this extra insulin may result in amino acids (excluding tryptophan) to be pulled into muscles for use, leaving a high level of tryptophan in the bloodstream, hence the need for a nap.
Have a great turkey day!
