Tryptophan Isn’t What Puts You Under on Thanksgiving. It’s the Carbs

Many people believe that the turkey consumed on Thanksgiving is the reason for the post-meal drowsiness, due to the amino acid tryptophan found in it. However, the reality is that it’s the high amount of carbohydrates consumed during the feast that actually makes you feel sleepy.

Carbohydrates, such as those found in mashed potatoes, stuffing, and pie, trigger the release of insulin in the body. This insulin release helps the amino acid tryptophan enter the brain, where it is then converted into serotonin and melatonin, which are known to induce relaxation and drowsiness.

Therefore, it’s not the tryptophan alone that is responsible for the post-Thanksgiving meal slump, but rather the combination of carbohydrates and tryptophan leading to increased serotonin and melatonin production.

It’s important to note that not all carbohydrates have the same effect. Simple carbohydrates, like those found in sugary desserts, can cause a spike in blood sugar levels and a subsequent crash, contributing to the feeling of fatigue.

Despite the common misconception about tryptophan being the culprit, it’s actually the carb-heavy sides and desserts that are more likely to blame for those post-Thanksgiving naps and food comas.

So next time you’re feeling sleepy after indulging in a Thanksgiving feast, remember that it’s not the turkey but rather the carbs that are putting you under. Enjoy the meal, but be mindful of your carbohydrate intake to avoid feeling overly drowsy afterwards.
