NewsHour: Can we blame it on the bird?
Dr. Markel: Most people blame it on simply stuffing one's stomach with too much food. More medically-minded folks cite the myth that a huge meal causes a diversion of the blood supply to the gastrointestinal system as it digests all that turkey, dressing, potatoes, and pumpkin pie. But in reality, the blood that is diverted tends to come from skeletal muscle tissue and is helped along by the heart's ability to increase the volume of blood pumped forward with each beat. In fact, the flow of blood and oxygen to the brain is rigidly controlled by the cardiovascular system and does not drop after any meal.
