Every year, on the fourth Thursday in November, the United States celebrates a holiday called Thanksgiving. Part of the tradition, along with watching football (the American version), is eating mountains of food, including a roasted turkey. And this is where Uncle George regales the guests with the turkey tryptophan myth – that is, eating a mountain of turkey, which he claims is high in tryptophan, makes you sleepy.
Because I know the average reader of this blog is pro-science and snarky, I post this article for you to embarrass Uncle George. Well, he’s probably a Trump supporter who wouldn’t know any science because it isn’t a pedophile in Alabama. Oh sorry, I did go there.
Back to Thanksgiving and the turkey tryptophan myth. Only a few countries celebrate Thanksgiving, and just a handful of countries eat turkey in any amount, other than the USA and Canada. Surprisingly, 87% of English holiday dinners will include turkey, a bird that is native to North America. So, I guess when gobby Uncle George (loyal Chelsea football fan) starts with the turkey tryptophan tosh, you can tell him to bugger off with this article.
Just in case you want to impress friends and family, the other places that celebrate Thanksgiving, similar 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, an Australian territory of like 1500 people. The only thing I thought that was on Norfolk Island was the Norfolk Island pine. And now I wonder if they import turkeys for the dinner.
For Americans, 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 tonnes 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!
Generally, everyone, after finishing this dinner, would want to take a long nap. Thus, we find the origin stories of the turkey tryptophan math. However, the science of eating, sleeping, turkey and tryptophan doesn’t support this myth. Not even close.
