Holiday good mood foods

At work, we joke that what really gets people depressed around the holidays is the saturation of stories in the paper about holiday depression.
That said, here's a good piece from Web MD about keeping your mood up by eating the "right" foods. It's good food for thought (so to speak) anytime of year--but especially now, when we're prone to binge.
Some ideas? Whole grain cereal with milk. Spinach with chicken.
