Hello, everyone! Let’s dive into an interesting topic today—food comas. You know that sleepy feeling you get after a big holiday meal? It’s not just in your head; it’s a real thing called postprandial somnolence. This is when you feel so full that you just want to lie down and take a nap.
When you eat a large meal, your autonomic nervous system, which controls things like your heartbeat and digestion, shifts gears. It has two main parts: the sympathetic nervous system, which gets you ready for action, and the parasympathetic nervous system, which helps you relax and digest food. After eating, your body focuses more on resting and digesting, which can make you feel sluggish.
During the holidays, turkey often gets blamed for making people sleepy. This is because turkey contains an amino acid called tryptophan, which helps produce serotonin in your brain. Serotonin makes you feel good and relaxed, and it can turn into melatonin, which makes you sleepy. But here’s the thing: tryptophan is also found in other foods like chicken, cheese, and eggs, and turkey actually has less tryptophan than chicken.
Carbohydrates are a big part of why you feel sleepy after eating. When you eat carbs, your body produces insulin, which helps move sugar into your cells for energy. Insulin also helps certain proteins move out of your blood, leaving more tryptophan behind. This extra tryptophan can then enter your brain more easily, leading to the production of serotonin and melatonin.
Interestingly, tryptophan can be stored in your body, so you might feel sleepy even after some time has passed since your meal. That slice of pie you had for dessert could be the final push your body needs to start making more serotonin.
It’s important to remember that everyone’s body processes tryptophan differently. If you’re not feeling well or are taking certain medications, your experience of a food coma might be different from others.
So, as you enjoy your holiday meals, now you know why you might feel like taking a nap afterward. It’s all about how your body processes the food you eat. And remember, it’s not just the turkey!
Feel free to share your thoughts about food comas and holiday meals. And if you’re curious about why turkey gets a bad rap for making you sleepy, check out more discussions online. Thanks for learning with us!
Design an infographic that explains the food coma phenomenon. Include key points such as the role of the autonomic nervous system, the myth about turkey, and how carbohydrates contribute to post-meal sleepiness. Use visuals and concise text to make your infographic engaging and informative.
After your next big meal, survey your classmates about their levels of sleepiness. Record what they ate and how they feel afterward. Analyze the data to see if there’s a pattern between the types of food consumed and the level of sleepiness experienced.
In groups, create a short skit that demonstrates what happens in the body after eating a large meal. Assign roles such as the sympathetic and parasympathetic nervous systems, insulin, and tryptophan. Perform your skit for the class to help everyone visualize the process.
Research other foods that contain tryptophan and how they affect the body. Prepare a short presentation to share your findings with the class. Discuss whether these foods have the same impact on sleepiness as turkey and why.
Write a journal entry reflecting on your personal experiences with food comas. Consider what types of meals make you feel sleepy and why you think that happens. Share your thoughts on how understanding this phenomenon might change your eating habits.
Here’s a sanitized version of the transcript:

Hello, everyone! Amy here on DNews. It’s the holidays! This means it’s time to visit family and enjoy a significant number of large meals, which often leads to that familiar feeling of lethargy known as a food coma. While it may sound amusing, a food coma is actually a medically recognized condition. Properly referred to as postprandial somnolence, it describes the sensation of being so full that you feel unable to move until you eventually fall asleep.
Medically speaking, a food coma results from a shift in activity within the autonomic nervous system. This system controls involuntary actions of organs, the heart, and glands, and includes the sympathetic nervous system, which is responsible for the “fight or flight” response, and the parasympathetic nervous system, which allows your body to rest and digest. After consuming a large meal, the autonomic nervous system tends to favor the parasympathetic nervous system, reducing your awareness of the sympathetic nervous system and making you feel sluggish.
Often, turkey is blamed for this sleepy feeling during the holidays. The myth is that tryptophan in turkey causes drowsiness. While there is some truth to this, tryptophan is an amino acid that produces serotonin in the brain, contributing to that satisfied feeling, and serotonin in turn produces melatonin, which makes you sleepy. However, tryptophan is also present in other poultry, meats, cheese, yogurt, fish, and eggs—foods that non-vegans consume throughout the year—so turkey isn’t solely responsible for the drowsiness, and it actually contains less tryptophan than chicken.
Tryptophan binds to other proteins in the blood, making it difficult to cross the blood-brain barrier on its own. Other smaller proteins can cross more easily, which prevents tryptophan from entering the brain and triggering the production of serotonin or melatonin. Tryptophan requires assistance, which it gets from carbohydrates. Yes, carbohydrates play a significant role in food comas.
Here’s how it works: consuming carbohydrates stimulates insulin production, which helps your body convert sugar into energy. Insulin also facilitates the movement of proteins from the bloodstream into cells. However, some proteins, like albumin, remain in the blood and bind to tryptophan. When protein levels drop after a rise in insulin, the relative amount of tryptophan increases, allowing it to cross the blood-brain barrier more easily and produce serotonin and melatonin.
Additionally, tryptophan can be stored in your body, meaning you can experience a carb-induced food coma long after finishing your meal. That slice of pumpkin pie might provide the carbohydrate boost your body needs to initiate serotonin production.
So, enjoy your holiday meals and understand why you might feel sleepy afterward. Keep in mind that how your body processes tryptophan-bound proteins can vary if you’re unwell or on certain medications, so everyone’s experience of a food coma may differ.
Speaking of turkey, Anthony and Cristen discuss why turkey gets a bad reputation for making you sleepy in another video. We’ll include a link in the description for mobile viewers.

Food – Any nutritious substance that people or animals eat or drink to maintain life and growth. – Eating a balanced diet with a variety of foods is essential for maintaining good health.
Coma – A state of deep unconsciousness that can be caused by illness or injury, where a person cannot be awakened. – After the severe head injury, the patient was in a coma for several days before regaining consciousness.
Tryptophan – An essential amino acid that is a precursor to serotonin, often found in foods like turkey and cheese. – Consuming foods high in tryptophan can help increase serotonin levels in the brain.
Serotonin – A neurotransmitter that contributes to feelings of well-being and happiness, often influenced by diet and exercise. – Regular exercise can boost serotonin levels, improving mood and overall mental health.
Melatonin – A hormone that regulates sleep-wake cycles, often produced in response to darkness. – Exposure to bright screens before bedtime can reduce melatonin production and disrupt sleep.
Carbohydrates – Organic compounds found in foods and living tissues, including sugars, starch, and cellulose, that provide energy. – Whole grains are a good source of carbohydrates, providing energy for daily activities.
Insulin – A hormone produced by the pancreas that regulates blood sugar levels by facilitating the uptake of glucose into tissues. – People with diabetes may need to take insulin to help control their blood sugar levels.
Digestion – The process by which the body breaks down food into small components that can be absorbed into the bloodstream. – Proper digestion is crucial for the body to obtain nutrients from the food we eat.
Nervous – Relating to the body’s network of nerve cells and fibers that transmits signals between different parts of the body. – The nervous system plays a critical role in controlling both voluntary actions and involuntary responses.
Energy – The capacity to do work, which in biological terms is often derived from the breakdown of nutrients in food. – The body converts carbohydrates into energy, which is used to fuel physical activities and bodily functions.
