I've come across opinions that depression (mood disorders, and some other disorders like impulse control or OCD) can be caused or made worse by neurotransmitter imbalances which are caused by deficiencies in certain amino acids resulting from poor digestion and absorption of proteins. It was true in my case, but I had to fix more than just diet. But yes, I managed to beat a serious depression I suffered from throughout most of my teens and early twenties.
