I continue to disagree because there is nothing to back it up, except in some
rare cases. A much bigger healer by far is the placebo effect. If
you think you are doing something to help your condition, you as spirit will
improve regardless of whether or not you really did something with nutrients,
supplements, or medications.
I too have overcome years of depression - and severe, suicidal, PTSD, without
meds, without nutrition. I did it with a spec of counseling (which was of
no help - except to point out that I had difficulties in life that could be the
cause) and loads of meditation. It was meditation that pulled me out of
both of them.
A proper nutrition helps all kinds of mental and physical illness, but to say
that it cures them is very misleading.
