p.s. There is very compelling evidence and clinical results from the psychology field that schizophrenia, panic disorder etc are indeed a result of chronic DEFICIENCY of nutrients/minerals, with Niacin being frequently supplemented with amazing success.
It's a chicken/egg scenario - Many in mainstream are of the belief the mind somehow 'goes wrong' - then the body exhibits symptoms, while the other side of the fence are gaining results with treating imbalances of the body, which alongside such treatment produces amazing mental/psychological health.
If i had to bat for either team - i'd opt for the latter.. personal experience aswell as many years of research has shifted me to belief also that a depleted/toxic/infected/imbalanced body leads to an imbalanced mind-set.
