Hi Radar
There's no official proof (as yet) that cutting out all the foods like salt, sugar red meat non organic is going to cure anyone.
However I know at least 2 friends that are plodding along nicely without medication on like Mediterranean diets, Garson diets, rainbow diets and certainly in one their cancer has shrunk and now gone (stomach cancer). The others have had low psa for quite a while.
I personally am trying to keep 100% Bio lots and lots of fruit, hot lemon drink first thing, no processed foods, plenty fish, plenty potatoes and verge and of course no dairy.
I'd recommend to read "the Rainbow Diet" book it is frightening execellent.
But each to their own and the main thing is to enjoy life.
I hope this helps.
It's my opinion that before long controlled test results will show what Gerson has been saying for years
Best of luck
Paul
