A study published by the International Journal of Cancer showed a
possible connection between regular mushroom consumption and a lower risk of
prostate cancer.
The researchers recruited more than 36,000 men ages 40 to 79 and found that men who consumed mushrooms once or twice a week — an average of about 3 ounces per serving — had an 8% lower risk of prostate cancer compared with those who ate no mushrooms. And among men who ate mushrooms three or more times per week, risk was 17% lower. The link held regardless of the men's intake of other vegetables and fruit or how much meat and dairy they consumed.
The findings cannot prove cause and effect, but suggest that mushrooms' high levels of ergothioneine, an antioxidant and potential cancer preventive, may play a factor. For information, shiitake, oyster, maitake and king oyster mushrooms have the highest concentrations of ergothioneine.
