Chili and Cornbread
Whether you get your protein from animal or plant sources, your body just can't function without it. For meat-lovers out there, chili is a great source of protein, especially when it's prepared with lean ground beef. Lean beef contains high levels of B6 and tryptophan, the proven mood-regulator. An even healthier option for your chili recipe is ground turkey.
Pack your chili full of beans: black, red, pinto and other types you like. Beans are a terrific vehicle for ingesting selenium and increasing levels of magnesium, a deficiency of which has been linked to depression [sources: Magee, Melone].
The perfect complement to this wintertime favorite is cornbread, which contains gluten, known for its ability to stimulate endorphin production [source: Cohen].
