Honestly, I find a lot of these food claims somewhat dubious. Coffee seems to have a new benefit or warning every year or so, making it good one year and a killer the next. I think genetics plays a greater role. Nevertheless, I do take vitamins and herbs and have for a long time. I still got PCa, tho. I remember reading something years ago about
diet and cancer, the gist was, "...even vegetarians get cancer." I think the greater concern is what's in the meat, red or otherwise, that we eat. I have gone to an organic diet and refuse to eat anything with any kind of hormone or antibiotic additive anymore. That's been for the past year.
I can't say that I feel any different, but I believe it to be the correct decision. Why? Lyle Alzado... remember him? Took HGH trying to make a comeback in his 40's. It's widely believed that the HGH triggered the tumor that killed him to grow at an exponentially faster rate with all that additional HGH in his body. This is a tumor that may have killed him, but under normal circumstances probably not until much later in his life. Maybe I'm being ridiculous, but that was enough to scare me away from any of those kinds of supplements... and eventually led me to the organic food decision. Maybe I'm wrong, but it makes sense to me...
I drink my morning coffee, have a beer or bourbon with dinner, and still have the monthly steak on the grill. If I was told I MUST give it all up, I would... mostly.
