A parade of food makes its way from the kitchen to the table to your plate. Your plate is piled high with all the trimmings: turkey, stuffing, mashed potatoes dripping with butter, green beans, and\u00a0cranberry sauce. The wine bottle makes its way around the table, followed closely by the\u00a0pumpkin and pecan pies.After chatting with relatives and taking a second helping of potatoes, you find yourself fast asleep under a blanket on the nearest couch.Have you ever wondered why Thanksgiving often ends in a nap? Many are divided as to why people often feel so sleepy after the big \u201cturkey day\u201d meal.What Is in Turkey That Makes You Sleepy?The cause of this post-feast grogginess has long been debated around the dinner table. Many attribute it to\u00a0tryptophan, an amino acid found in turkey, but despite the persistence of the myth, turkey isn\u2019t to blame for the Thanksgiving nap\u201cLike many other foods, turkey does contain tryptophan, which is essential for the production of serotonin,\u201d says Tessa Wellmon, RD, a registered dietician at UPMC Hamot. \u201cSome serotonin is then converted to melatonin (a hormone that controls sleep cycles). Turkey, however does not have more tryptophan than other meats, dairy products, nut, or seeds that you would consume daily.\u201dAlong with other meats, dairy products, nuts, and seeds, even\u00a0vegetarian fare like tofu includes tryptophan. So, if tryptophan caused drowsiness, we would feel groggy after eating just about any protein (which is not the case).So if tryptophan isn\u2019t the culprit, why do we feel so sleepy after our Thanksgiving meal?While tryptophan can help people relax, it isn\u2019t the only amino acid in turkey. The other amino acids would outweigh tryptophan\u2019s effect in reaching the brain. However, eating carbohydrates \u2013 like in stuffing or pie \u2013 causes your body to release insulin, which removes non-tryptophan amino acids from your blood.It seems the enormous amount of food we often consume during the holidays is more to blame than turkey alone. So, if you want to stay awake on Thanksgiving Day, opt for\u00a0smaller portions\u00a0and skip the second helping of pie. You can always enjoy the leftovers the next day!Turkey Making You Sleepy Is a MythTurkey might get the blame for your post-meal nap on Thanksgiving, but there are other factors for your sleepiness.The first is overeating in general. Eating high-calorie meals tends to lead to fatigue afterword, according to a 2018 study.That\u2019s especially the case when it comes to the type of food people generally consume at their Thanksgiving meals. Many of the most popular Thanksgiving dishes are carbohydrates that rank highly on the glycemic index, which ranks foods based on their ability to raise a person\u2019s blood sugar. Foods high on the glycemic index scale will raise your blood sugar more quickly, which can cause the release of insulin and can trigger sleepiness. Those include potatoes, white bread, and high-glucose foods such as pie.Drinking alcohol can help make you tired as well.And then there\u2019s the exhaustion of the day in general. Waking up early to begin meal preparation, and the work that goes into it, can cause fatigue.How to Avoid That Sleepy FeelingIf you want to avoid the dreaded Thanksgiving food coma, there are steps you can take:Don\u2019t skip other meals: Avoiding eating earlier in the day can make it more likely that you\u2019ll overeat when the turkey, stuffing, potatoes, and more are in front of you.Pay attention to your carbs: Carbohydrates release insulin into your blood, which enhances the effect of tryptophan. Limiting them during your Thanksgiving meal can help you stay awake.Eat slowly: It\u2019s easier to overeat when you eat quickly because you may not realize you\u2019re full until it\u2019s too late. Taking your time during Thanksgiving dinner may help you avoid overeating.Eat smaller portions: This also helps you avoid overeating. Try a smaller helping of stuffing to avoid getting stuffed.Don\u2019t forget your vegetables: Vegetables such as sweet potatoes, yams, corn, lima beans, carrots, and peas cause a slower rise in insulin levels than many of the carbs you eat on Thanksgiving.Cut back on dessert: Sugary, high-carb desserts like pumpkin pie can raise the likelihood of that tired feeling.Avoid too much alcohol: Consuming alcoholic beverages can make you tired, especially in the short term after drinking them.Take a walk: Going for a walk around the neighborhood after dinner can help with your digestion.Editor's Note: This article was originally published on November 23, 2014, and was last reviewed on July 13, 2023.SourcesLouise L.
