Why does turkey make you tired?

The truth is:

* Turkey doesn't contain more tryptophan than other foods. Tryptophan is an amino acid that gets converted into serotonin and then melatonin, which can promote sleepiness. However, the amount of tryptophan in turkey is similar to other proteins like chicken and beef.

* The "turkey coma" is likely due to a combination of other factors, such as:

* Large meal: Eating a large meal can make you feel sleepy due to increased blood flow to your digestive system, which can decrease blood flow to your brain.

* Carbohydrates: A traditional Thanksgiving meal is often heavy on carbohydrates, which can cause a blood sugar spike followed by a crash, leading to fatigue.

* Alcohol: Alcohol consumption can also contribute to tiredness.

* Relaxation and inactivity: The holiday atmosphere often involves relaxing and not being as physically active, which can make you feel tired.

In conclusion: It's not the turkey itself that makes you tired, but rather the combination of other factors associated with Thanksgiving meals and the holiday atmosphere.
