Since I had my prostatectomy a year ago, I've followed a pretty rigid "anti-PCa" diet (drawn from many sources and as Bri says, what feels right).
My PSA remains undetectable but I don't know if this is because i) all the cancer was removed with the prostate, ii) the cancer cells that are still left are yet to show their presence iii) my dietary changes are keeping any remaining little blighters at bay.
Therefore, only time will tell as to whether putting soya milk on my muesli (fortifide with every anti-oxidant nut, seed and berry you can think of) and drinking copious amounts of green tea and a litre of pomegranate juice a week have been worthwhile.
The downside I find in following a strict regime is that, I now deny myself some of the things I used to eat, not wishing to upset (as I think I could) the good results so far - crazy really.
