Have you ever thought about what makes you sleepy after eating turkey? Turkey contains tryptophan, which is a natural sedative. Although, that alone does not make you sleepy after eating turkey. When you eat sugars with tryptophan, they absorb the tryptophan, which raises the serotonin/melatonin in our brains. When that happens, we become drowsy. Examples are cranberry sauce, potatoes, and pies for dessert. Happy Thanksgiving!!!!!!
