Myth Busted: Turkey Doesn’t Make You Tired!

Sliced TurkeyPeople often say that eating turkey makes you tired. And after consuming a gut-clogging Thanksgiving dinner, most of us feel a bit sluggish. But, according to experts, turkey isn’t the true culprit.

Turkey contains tryptophan, an amino acid that’s a component of the brain chemical serotonin. It gets converted into a sleep-inducing hormone called melatonin.

But turkey isn’t alone in containing tryptophan. It’s also in other poultry. In fact, all these foods have more tryptophan than turkey – including, per 200-calorie serving, crab, fish, duck and even spinach.

According to Live Science, it’s not the turkey that makes you tired but all those carbohydrates:

Consuming carbs triggers the release of insulin, which removes most amino acids from the blood, but not tryptophan — that dearth of competitors allows tryptophan to enter the brain and form serotonin and, ultimately, melatonin.

Moreover, the blood sugar spike is followed by a low-energy crash. Add alcohol into the equation (and listening to your Uncle Bruce blabber endlessly), and it’s no wonder that so many of us want an afternoon nap.
