I had schizophrenia and still have, but it's now not as prevalent after years of eating mostly vegetable, raw, and very ripe, fermented sometimes (like when peppers, onions, garlic for example are getting soft, people usually call them "rotten", but I prefer them like this actually, there can even be some bacteria formation on it, it doesn't matter). That with regular walking/running outdoor helped me so much. A typical daily meal: Red/orange peppers, onions of all kind, spinach, mushrooms, tomatoes in a bucket, rince, add lemoon juice on top, and eat slowly, masticating properly, doing nothing else, fruits as well before or after clementines, grapes, figs, persimmons, dates, walnuts, amonds (depending on the season). (I'm not vegan but I rarely eat other things as I'm full with this, I started this because it was a cheap way to eat)
