As I understand it, the blood sugars and corresponding insulin levels
directly impact the serotinin levels which directly effect the mood. (Prozac
works because of its effect on serotinin). I am not aware of any other
psychoactive substances, but depressed people are sure known to attack the
carbs in eating binges and thereby start a cycle.
I will look for the references if needed
