Turkey and tryptophan – let’s science the shit out of this

turkey and tryptophan

A tiny handful of countries, most notably the US and Canada, celebrate a holiday called Thanksgiving. In the USA, the holiday is held on the fourth Thursday in November and more or less starts the so called holiday season which ends with New Year. In most of Canada (excluding the Atlantic provinces), the holiday is held on the second Monday in October. Invariably, there are stories about turkey and tryptophan, making you just want to take a nap hearing about it.

For trivia purposes only, the other places that celebrate a similar Thanksgiving to the USA and Canada are Liberia (which is populated by descendants of freed slaves who returned to Africa from the US), Grenada (a small English-speaking island in the Caribbean), Puerto Rico (a Spanish-speaking territory of the USA), and Norfolk Island Australia. Australia? I have no clue if they all talk about turkey and tryptophan over dinner.

Generally, the holiday celebrates white English settlers arriving in North America. The tales usually include some peaceful sharing of food between the white settlers and native Americans (a nice myth without much actual historical support) prior to the first winter. Canada’s backstory on Thanksgiving is much more complicated, including ships getting stuck in ice and other legends – it is very Canadian.

In both Canada and the USA, the celebration includes tons of food (per person) usually including a roast turkey. Other foods may include mashed potatoes, yams (sweet potatoes), other meats, pies, corn, stuffing, and more food. It is a high calorie meal of epic portions!

There’s a legend that eating this meal, specifically the turkey, fills your body with tryptophan, and you fall asleep.

Nice story, but the science of eating, sleeping, turkey and tryptophan doesn’t support this myth. Not even close. Continue reading “Turkey and tryptophan – let’s science the shit out of this”
