Thanksgiving is a time for tradition.
Roast turkey with stuffing and cranberry sauce. Family members gathering from near and far. It's also a time for strongly held beliefs, but some ideas associated with the big meal and holiday eating in general are just so much gobbledygook. One familiar bit of folk wisdom holds that it's the turkey itself that leaves holiday diners snoozing. In our own bodies, tryptophan is a precursor to serotonin, a substance associated with sleep regulation.
