Abstract

In vivo and in vitro evidence has shown that mushrooms have the potential to prevent prostate cancer. However, the relationship between mushroom consumption and incident prostate cancer in humans has never been investigated. In the present study, a total of 36,499 men, aged 40–79 years, who participated in the Miyagi Cohort Study in 1990 and in the Ohsaki Cohort Study in 1994 were followed for a median of 13.2 years. Data on mushroom consumption (categorized as <1, 1–2 and ≥3 times/week) was collected using a validated food frequency questionnaire. Cox proportional hazards regression analysis was used to estimate multivariate hazard ratios (HRs) and 95% confidence intervals (CIs) for prostate cancer incidence. During 574,397 person‐years of follow‐up, 1,204 (3.3%) cases of prostate cancer were identified. Compared to participants with mushroom consumption <1 time/week, frequent mushroom intake was associated with a decreased risk of prostate cancer (1–2 times/week: HRs [95% CIs] = 0.92 [0.81, 1.05]; ≥3 times/week: HRs [95% CIs] = 0.83 [0.70, 0.98]; p‐trend = 0.023). This inverse relationship was especially obvious among participants aged ≥50 years and did not differ by clinical stage of cancer and intake of vegetables, fruit, meat and dairy products. The present study showed an inverse relationship between mushroom consumption and incident prostate cancer among middle‐aged and elderly Japanese men, suggesting that habitual mushroom intake might help to prevent prostate cancer.

Four types of Mushrooms which are most beneficial are (1) Reishi (2) Turkey tail (3) Shitaki and (4) Maitaki.

Fresh ones are not available near us..so I use a supplement capsule which contain a combination of powder of these mushrooms.

What about psilocybin ? I recommend a wild mushroom pizza to foodies ..

[MateoBeach in reply to Hidden]

Mmmmm. Psylocybin mushroom pizza? Deliver me a large supreme. Pepperoni optional! Have you read "How to Change Your Mind" by Michael Pollan? I have done the "experiment" of monitored high-dose single session treatment. And yes it is life changing for cancer patients. "But first: Are you experienced . . . " (Jimmy H)

[Hidden in reply to MateoBeach]

Yet to read the book . We had two good experiences with ayahuasca however ..I felt a great sense of well being and connectivity

to the world .a week later i got my first clears scans .. that’s felt great .

[MateoBeach in reply to Hidden]

You would like it then. A great read, or listen to the audiobook while doing walks, etc. I was inspired to try the experiment modeled after the original experiments and recent research with cancer patients: a single high-dose mushroom experience in a safe comfortable and monitored setting with positive expectations (set and setting).

Was very transformative for me also. Four hours of being able to ask any question (of my deep Self or of the universe) and have insightful answers come back immediately. Anything. The meaning and purpose of my life; Best direction for me now; Death altogether! Ha! How liberating, even for a very experienced lifelong meditator. When I am able to come visit you will share some insights from that. I actually flew to Canada to have a dear and trusted friend be my monitor/guide for it. (Besides he grows really excellent mushrooms.)

When I was in my prime (long long time ago) they used to call me a fungi.....that's why the ladies always kept in the dark....

Good Luck, Good Health and Good Humor.

I felt that there was a fungus amongst us?.. Now I know? Luv ya man!😘

[treedown]

I eat all of the mushrooms Learnall mentions weekly as well as others I have found references to in relation to cancer. Not all are available in raw edible form which is my preference so I add the powder form to bone broth or tea. I also eat Lions Main, Oyster, Queen Oyster, White Button, Bunapi-shimeji, Chantrelle when in season.

I guess I will see how that works out for me. Not a big fan of the psilocybin, tried it once maybe twice decades ago.

[Hidden in reply to treedown]

Hey tree! At our local farmers market they have a “ mushroom farmer” a varied array of fungi... mmmm

[treedown in reply to Hidden]

Very cool, my local food coop keeps a really nice selection in stock. Also Costco here has Shitake and White Button for great deals and they are organic. Needless to say I eat quite a lot of mushrooms.
