Eating turkey makes you sleepy because it contains tryptophan: FALSE

Most people feel sleepy after Thanksgiving and most people blame it on the tryptophan that is in turkey.  However, the levels of tryptophan in turkey are not nearly enough to affect one's energy level.  In fact, a person would have to eat more than an ENTIRE turkey in order to feel the affects of tryptophan--and even then, it would have to be eaten on an empty stomach because that is how tryptophan reacts.  Furthermore, cheese and pork contain higher levels of tryptophan per serving than turkey does.  The reason we feel sleepy after Thanksgiving dinner is because we eat so much, not because the trytophan is drugging us.
