Dont think the changes in diet/habits is effecting whether you have pc or not. If you are only reporting <1% cancer in one of twelve cores, I think I would slow things down and make sure. If that biopsy is true, you have an extremely low grade low volume case of cancer going on, and you would would be a good candidate for almost any treatment, even AS>
It might be worth being on AS, continue to have the periodic PSA tests, and have another biopsy in a years time. Even though I am a surgery guy (whole different set of numbers than you), not sure I would want to have surgery this soon with such a low reading. But that's just me, I didn't have any other sensible options in my case.
Keep us posted, and good luck with whatever you do in the end.
