Every year millions of families gather around their tables to enjoy delicious Thanksgiving dinners. For students, it’s a great chance to get a home cooked meal (turkey, stuffing, potatoes, and pie!) and interact with family members they haven’t seen in a while. But once the meal is done and the table is cleared, suddenly you feel quite tired. The dreaded food coma. Was it the tryptophan in Grandma’s turkey that’s the culprit, or could the extra three slices of apple pie have been the source of this sleepiness?

Q: What is the cause of my Thanksgiving food coma? (Is it the tryptophan or the overeating that makes me tired?)
A: Truth be told, the cause of the “Thanksgiving food coma” is none other than over eating at the holiday meal.
Mrs. Duffy explains:
Although tryptophan has been commonly blamed for inducing the sluggish effect many claim to experience post consumption of their festive turkey dinner, the fact is your turkey consumption does far less to cause you to want to take a nap post meal than does the actual amount of food you ingested during the traditional feast.
Keeping it simple, there is indeed a link between tryptophan and a chemical produced by the brain called serotonin. Tryptophan is an essential amino acid that the body cannot make itself and is found in poultry (like turkey), meat, dairy products, fish, and eggs. Serotonin affects mood as well as producing the hormone melatonin, which helps to control our sleep and wake cycles. This association between tryptophan and serotonin is not the sole culprit of that groggy feeling that beckons many to crawl off to the nearest sofa right after dessert on these holiday occasions. Increased carbohydrate intake, whether it’s a second serving of mashed potatoes or another slice of pie, also has a supporting role in driving the need to catch a little shut-eye once the banquet table has been cleared.
The real deal is that this lazy feeling is more directly related to over indulgence. Let’s be honest. Thanksgiving is a time that many people tend to over eat. Simply put, overeating causes the digestive system to slow down. And then the belt loosens to accommodate the expanding waist due to processing of all the food and the eye lids get a bit heavy… You get the picture, right?
One solution to avoiding this pressing desire to sleep and the uncomfortable over stuffed feeling can be practicing a bit of portion control. Knowing what your suggested serving sizes are for carbohydrates before you plate up can be a tremendous guide when it comes to putting food on your plate. For example, a single serving of mashed potatoes is half a cup or about half the size of your fist. It’s also useful to budget your calorie salary for the day. What? You don’t know what your calorie salary is? No worry. Check out the free downloadable MyFitnessPal app for help with calculating yours.

So it was those extra slices of pie. Now you know to pace yourself when indulging in your holiday feasts, so you don’t over indulge and find yourself in a post dinner slump!
