...I have a personal connection to this. My brother is currently trying this as well as he also has prostate cancer.
JP, can you say if your brother had any success with the baking soda thing?
I've just completed a couple of baking soda 'protocols' which is basically eating more alkaline-forming foods (mostly plants and veggies) and baking soda as needed to keep my urine pH at 8.0 and above. I did two 6 to 8 day runs at this, then a PSA test yesterday. The results were that my PSA went up, from 6.9 a month ago to 7.3 today.
Sigh, well it did look promising from the couple of you tube people who claimed it cured them, one with stage 4 PC. I'm still of the opinion that keeping your body pH at 7.0 or above through healthy eating is a good goal; it turns out that most plants are on the alkaline side.
So I'm moving on with an MRI coming up in two months. I guess of greater concern is that my PSA continues to rise, started at 6.3 ~4 mo ago, 6.9 a mo ago and now 7.3. I've gone vegan, I'm fasting (IM) 16 hrs/day, lost 20 pounds in the last 2 months, exercising 5 to 6 days per week and I'm not slowing it down. I fear that after my final PSA just before my MRI in Aug and chat with the urologist I'll need to make a decision between surgery or radiation.
The only thing I have not done yet is a focused low-carb diet (somebody recommended that to me on this forum but I can't remember who), and stress reduction techniques (breathing, yoga, meditation). That will be started shortly.
I'm starting to feel that this is a freight train that I can't stop by any means other than medical intervention. I guess that's just the nature of the beast.
