Gerson therapy fails on an ongoing basis for many cancer sufferers, casually I looked it up recently in forums because my aunt has a lymphoma.
As per using food as medicine, I am your man, my diet is awfully healthy and I juice. It feels great and helps my disease but I am still very sick, it is crystal clear food is not a medicine for many diseases especially the chronic ones.
Easy to see in fact, what caused the disease? Food? No? Then food cannot heal it. Diet only heals people who got sick because of their unhealthy diet...
