People who suffer from depression often lack vitamin B. There are plenty of mood-lifting foods, though, that can come to the rescue. Avocados, for example, are one of the richest sources of this vitamin, and bananas (packed with magnesium) can help relieve stress and anxiety. The selenium found in Brazil Nuts and the in folic acid found in asparagus can also help stabilize your mood. Other "happy foods" are orange juice, oatmeal, turkey, low fat cheese and chocolate!
