Thanks to all who have replied and a few specific comments:
English Alf and BB_Fan. I agree that ordinarily there's no way to be sure what my PSA would have been without intervention. However, prior to starting these tests, my PSA was on a well established upwards trend with a doubling time of 7 months extending over two years. As I understand it, my doubling would most likely continue at that rate, which gives an expected 0.4 now and 0.6 in another 3 months. So I will take anything less than those figures as reasonable proof that what I have been doing the previous three months has had some effect. On that basis, nothing so far.
Regarding the
Pomegranate juice: My particular supermarket brand comes from Turkey (Ersu brand), and it is sweet and syrupy which I like. The label says 100% pomegranate juice (from concentrate), so I have to assume there is no added sugar, and it is just the natural fruit sugar. Each serving has 484KJ which works out to about
120 calories or about
5-10% of my recommended daily, whatever that is. So I can live with the taste and calories, but I agree that the concentrate (pills) is a good choice for those who can't.
Jerry L I'm not sure that Abiraterone will be available in my area, but will certainly ask my uro on my next visit. If not, I may be a candidate for some other trial, even if it only turns out to be in the placebo arm.
