Eat mushrooms and reduce your risk of prostate cancer

Men who eat mushrooms at least 3 times a week reduce their risk of prostate cancer by 17 percent. Especially men who have passed 50 can benefit from that effect.


Eat mushrooms and reduce your risk of prostate cancer


Study
Epidemiologists from Tohoku University School of Public Health in Japan analyzed data from men who participated in two large studies, the Miyagi Cohort Study and the Ohsaki Cohort Study. Those studies started and ended in 1990-2014 and 1994-2006 respectively. When the studies started, the men were 40-79 years old.

The researchers knew the diet of the men and examined whether consuming mushrooms had an influence on their risk of developing prostate cancer. The most commonly consumed mushrooms in Japan are the shiitake, maitake, eringi and enoki.

Results
Doctors diagnosed prostate cancer in 3.3 percent of study participants.

The risk of prostate cancer decreased as the men ate mushrooms more often. In the group that consumed mushrooms 3 times a week or more, the risk of prostate cancer was 17 percent lower than in the men who never ate mushrooms. This association only became stronger as the researchers brushed away the effect of all kinds of other lifestyle factors.

When the researchers broke down their data further, they found that only in men over the age of 50, a high mushroom intake was associated with a significantly lower risk of prostate cancer.

Conclusion
"This finding suggests that habitual mushroom intake might help to reduce prostate cancer risk," the researchers write. "Further studies in other populations and settings are required to confirm this relationship."
