I'm always skeptical about the foods as cures posts here, but the last couple of patient news letters from City of Hope have highlighted some of their studies on food and food extracts as tools against prostate and breast cancers. The mushroom study included human in vivo via "white mushroom powder."
So I asked Dr. Dorff about white mushrooms and just eating the real food to get the compounds (as many here jump onto doing when a food study comes out based on compounds/extracts injected into mice), since I'd started eating them daily.
Her response was that "it was 28 pills per day on our trial...it was a big chunk of powder (she held her hand out to demonstrate)." I said just eating mushrooms wasn't the same thing, and she said "I don't know, seems like we really had to escalate the dose in the trial to get results."
She did add that there was "other stuff that seemed to be helpful like pomegranate juice, lycopene, soy, and green tea, so having those things in your diet has to be a positive." She didn't mention blueberries but they are one of the things painted on the walls.
"Seemed to be helpful" is a long way from cure in my mind, but like I say in many responses here, they won't hurt you, but I wouldn't expect them to cure you.
My bottom line is be skeptical of studies that don't include human trials, and realize that compounds and extracts injected into rodents don't always translate into the same results in humans, and would probably require much larger doses. And I've seen smarter people than me post here that they are leery of supplements because of dosing.
Just thought I'd share those comments. I love mushrooms and will continue eating some grilled ones frequently, but for the taste, not in hopes of being a real impact on my aPCA.
