Researchers say that we can blame turkey for many things, but one thing we CAN’T blame it for is that nap we always take after eating a big Thanksgiving dinner.
Some researchers say that tryptophan, an amino acid found in turkey, has proved itself to be an effective sleep aid, causing that post-Thanksgiving meal sleepiness. But poultry expert Scott Beyer says that while tryptophan can make people sleepy, it is not solely responsible for that post-Thanksgiving meal sleepiness.
Only a small percentage of tryptophan can be found turkey, Beyer says. The sleepiness caused after a Thanksgiving dinner probably has more to do with the actual meal, which is high in fat and carbohydrates, and if you had any alcohol with the meal.
