My mother was an RN & a "health nut." She made all our food home-made: bread, everything. We picked our fruit out in the countryside, in the mountains etc. (my father was a geological surveyor so we moved around, lived in all regions). We had fresh squeezed OJ every morning. But I was still super manic. At college, I worked on a Mennonite goat farm. Organic. Made my own yogurt from the goats' milk. Ate all that healthy fresh picked Mennonite food. But was super manic & would crash to horrible illnesses with high fevers & strep throat, etc. That's my story. Everyone is different! I think a healthy diet is important but from all I've read (tons), bipolar disorder is a genetic brain condition.
