Jim, there are loads of threads on here about diet. We have had members here who commit themselves entirely to the Jane Plant diet (you can buy her book on Amazon), others who keep it in mind but not slavishly, others who follow the Prostate Cancer Research cook book (which you can buy on Amazon). Lots of members have taken Pomi-T for years.
It isn't that diet can't be discussed on here; it is about balance. Jane Plant died, despite her diet. Almost all of the forum members who were most evangelical about it are dead. There is no convincing research to say that diet makes any difference once you have been diagnosed with prostate cancer - but I cut dairy and red meat out of John's life as soon as he was diagnosed just in case. Following a strict anti-cancer diet is not a good idea when you start RT - any supplements should be checked with the onco. But the general principles of Plant and PCR - reduce dairy and red meat, increase soya, alium, tomatoes, broccoli, etc - are good health advice anyway. Basically, a Mediterranean diet is a good thing, except during RT.
