The Great Tryptophan Lie: Eating Turkey Does Not Make You Tired

While you’re battling your cousins for the best napping spot after Thanksgiving dinner, feel free to use this as a diversion tactic: It’s a myth that eating turkey makes you tired.

It’s true that turkey contains L-Tryptophan, an amino acid involved in sleep. Your body uses it to produce a B vitamin called niacin, which generates the neurotransmitter serotonin, which yields the hormone melatonin, which helps regulate your sleeping patterns. However, plenty of other common foods contain comparable levels of tryptophan, including other poultry, meat, cheese, yogurt, fish, and eggs.

Furthermore, in order for tryptophan to produce serotonin in your brain, it first has to make it across the blood-brain barrier, which many other amino acids are also trying to do. To give tryptophan a leg up in the competition, it needs the help of carbohydrates. Registered dietitian Elizabeth Somer tells WebMD that the best way to boost serotonin is to eat a small, all-carbohydrate snack a little while after you’ve eaten something that contains tryptophan, and the carbs will help ferry the tryptophan from your bloodstream to your brain.

But Thanksgiving isn’t exactly about eating small, well-timed snacks. It’s more about heaps of potatoes, mountains of stuffing, and generous globs of gravy—and that, along with alcohol, is more likely the reason you collapse into a spectacular food coma after your meal. Overeating (especially of foods high in fat) means your body has to work extra hard to digest everything. To get the job done, it redirects blood to the digestive system, leaving little energy for anything else. And since alcohol is a central nervous system depressant, it also slows down your brain and other organs.

In short, you can still hold turkey responsible for your Thanksgiving exhaustion, but you should make sure it knows it can share the blame with the homestyle mac and cheese, spiked apple cider, and second piece of pumpkin pie.

Why Are Decaf Coffee Pots Orange?

The orange spout and handle on a decaf coffee pot have saved many caffeine lovers from having a terrible morning. Like the orange on a traffic cone, the color has become a signal both to the people who drink coffee and the servers who pour it. But the shade wasn't merely chosen for its eye-catching qualities; orange is a piece of branding left over from the original purveyors of decaf java.

According to The Cubiclist, decaffeinated coffee first arrived in America via the German company Sanka. Sanka (a portmanteau of the words sans and caffeine) sold its coffee in stores in glass jars with orange labels. The bright packaging was the company's calling card, and because it was the first decaffeinated coffee brand to hit the market, consumers started looking for the color when shopping for decaf.

In 1932, General Foods, which has since merged with Kraft, purchased Sanka and got to work promoting it. To spread the word about decaf coffee, the company sent orange Sanka coffee pots to coffee shops and restaurants around the country. Even if the waitstaff wasn't used to serving two types of coffee, the distinct color of the pot made it easy to distinguish decaf from regular.

The plan was such a success that orange eventually became synonymous not just with Sanka, but all decaf coffee. Other coffeemakers began offering decaffeinated alternatives, and when marketing their products, they chose the color Sanka had already made popular.

The reason for the orange coffee pot is just one of decaf's not-so-mysterious mysteries. Here's some of the science behind how exactly coffee makers get the caffeine out of the beans.
