Eat protein first, then go lightly on the carbohydrate if want to stay alert. Caffeine can be an effective antidepressant. Despite its bad rap, caffeine can do some good. For mild cases of depression which don't need medical attention, a little caffeine can be an effective antidepressant. It has the added benefit of remaining effective without an ever-increasing dosage daily to achieve the same effect.
Folic acid is also an important counter to depression.
Folic acid deficiency has been linked to depression in clinical studies. This deficiency causes serotonin levels in the brain to decrease. Psychiatric patients with depression have much higher rates of folic-acid deficiency than the general public. Depression can be relieved by as little as 200 micrograms, an amount easily obtained in a cup of cooked spinach or a glass of orange juice. A lack of selenium can cause bad moods.
