Mushrooms сan protect men from prostate cancer, study says

September 13, 2019  20:27

Japanese researchers have found a link between eating mushrooms and lowering the risk of prostate cancer. Although the effect is relatively small, the results are likely to inspire further research, Medical News Today reported.

The National Cancer Institute predicts that 174,650 new cases of prostate cancer will be reported in the US in 2019.

Although the treatment for this type of cancer is constantly improving, there is no way to cure it or a way to prevent it. However, evidence suggests that a healthy diet can reduce the risk of illness.

Scientists recently conducted a study and found that mushrooms can help prevent prostate cancer.

As it turned out, some mushroom compounds have anti-cancer, anti-inflammatory and anti-diabetic properties. More specifically, studies on both cultured cells and animal models have shown that extracts of certain types of fungi can slow tumor growth.

Researchers have found that the fungus extract reduces the level of specific prostate antigen (PSA) - the main biomarker of prostate cancer - and increases the body's immune response to cancer.

Researchers have access to data on 36,499 Japanese men aged 40 to 79 years. Scientists used questionnaires to collect information on diet, medical history, levels of physical activity, smoking, drinking habits, educational levels, and more.

Participants were divided into five groups depending on the consumption of mushrooms:

almost never: 6.9% of participants

once or twice a month: 36.8%

once or twice a week: 36.0%

three or four times a week: 15.7%

almost every day: 4.6%

During the observation period, 1204 cases of prostate cancer were recorded, which amounted to 3.3% of the participants. After examining the mixed variables, the researchers noticed that compared with those who ate mushrooms less than once a week, those who ate mushrooms once or twice a week had a 8% lower risk of prostate cancer. Those who ate mushrooms three or more times a week had a relative risk of 17% lower.

However, it is worth noting that the increase in the incidence of prostate cancer between those who eat less mushrooms and those who eat more is only 0.31% (3.42% compared with 3.11%, respectively).

Also, the effect was significant only in men older than 50 years. The authors believe that this may be due to the fact that prostate cancer is less common in young men.
