Frequent consumption of mushrooms and cruciferous vegetables may help inhibit the formation and growth of cancerous cells and tumors in the stomach, colon, and rectum.

​This study looked at how the intake of mushrooms and cruciferous vegetables affects the risk of developing stomach and colorectal cancer. Researchers followed 632 Japanese men and women, monitoring their diets and incidence of colorectal and stomach cancer. 

Researchers discovered subjects who ate the most amounts of cruciferous vegetables had better chances of preventing both stomach and colorectal cancer. Similar trend was observed among high consumers of mushrooms, but it was only for stomach cancer. This study strengthens the body of evidence that generous intake of mushrooms and cruciferous vegetables may confer individuals with significant protection against stomach and colorectal cancer.
