I will weigh in with my standard answer on what I feel on the subject, and it is based on the opinions of my long term GP, my uro/surgeon, and my radiation oncologist.
(Disclaimer: being on a heart healthy or Mederteranian type diet would have good overall health aspects for any person)
As far as diet, my radiation doc says that the cat is already out of the bag, even if a certain food, tea, juice, etc could be proven beyond a shadow of a doubt to improve things, by the time you are dx with cancer, it would way to late to help. She said a lot of men jump on that wagon because they either feel false guilt for getting cancer, or they want to feel like they have somesay so or control in the cancer.
As far as supplements, and i have discussed this at length with all 3 different types of my doctors, including the dietician at the oncology rehab program I am about to start, is that none of them can be proven to help pre or post cancer dx. I think my GP said it correctly, when he said that all men end up with is having expensive urine.
They agreed that there is nothing wrong with cancer being a wake up call to healthier choices and lifestyle changes. Doesnt mean you give up on life and not even try. All agreed, that quitting smoking is still the number 1 health change you can make, if you are a current smoker. I have noticed whenever that subject has been mentioned here at HW, it gets dropped real fast. All the dietary changes or supplement use will never have the single ability to help your remaining life as much as quitting smoking. All my doctors agree with that.
I know my answer won't be the popular one in this case. We all have our vices (mine is sweets) and I am trying to learn moderation there, and no, I don't have or have ever had any problem with diabetes.
In the end, each of us will do what we think is right for ourselves. And will never agree to the merits or lack of merits with the dietary and/or supplement changes.
