Myth: Eating turkey makes you sleepy

Eating turkey doesn’t really make you sleepy. On the contrary, soybeans and beef contain higher concentrations of tryptophan. Apparently the tryptophan levels in a turkey causes blood levels of amino acids to rise, but not enough to create the sedative effect.
From MythBusters:

However, what does tend to make people exceptionally drowsy is eating a big, heavy meal — Thanksgiving dinner, for example. Blood is diverted to the digestive system to help tackle all the fats and carbohydrates you’ve consumed, which decreases blood flow to your brain and makes you feel lethargic. Drinking alcohol — while watching football or during the meal — only makes matters worse. So even if you didn’t eat any turkey, you’d still feel like taking a nap afterward.
