We’ve all been there: Asleep (or dozing) on the couch after a big Thanksgiving meal. The turkey’s the star of the show, so the poultry must be responsible for making you so darn tired—right? 

Let’s Start With the Facts…

Turkey does contain tryptophan, an amino acid that’s associated with sleep

Your body uses tryptophan to create a B vitamin called niacin, which helps to create a neurotransmitter called serotonin, which gets converted to a hormone called melatonin

You’ve probably seen melatonin pills in the drugstore alongside other natural remedies. Melatonin is known for inducing sleep, so it makes sense that some people have made the connection between turkey and drowsiness.

So Does Eating Turkey Really Make You Sleepy?

Here’s the thing: Chicken, meat, cheese, yogurt, eggs, and fish also contain tryptophan, according to Sleep.org. These foods aren’t usually blamed for making people tired, but poor turkey takes all the heat—especially around Thanksgiving. 

Furthermore, consuming tryptophan doesn’t impact your serotonin levels right away. There are a ton of amino acids in foods like turkey, and all of these amino acids have to compete to get to the brain. Since tryptophan is often one of the least represented amino acids in these foods, it doesn’t always make it. 

There is a way to give it a boost, however. Carbs release insulin, which lowers the levels of the other amino acids and allows tryptophan to more easily get to the brain. 

So, if you’re feeling sleepy after indulging on Thanksgiving, it’s probably not just the turkey that did it—it’s also all that stuffing and mashed potatoes you had on the side.  

More than likely, though, you’re tired because Americans eat a lot of food on Thanksgiving. Stuffing your face takes energy, people!
