A recent systematic review found that people who consumed more cruciferous vegetables, such as broccoli, cabbage, cauliflower or Brussels sprouts, had a 20% lower risk of colon cancer compared to those who consumed less.
The researchers analyzed data from over 17 studies, comprising a total participant pool of 639,539, with 97,595 cases of colon cancer. Including 20–40 grams of cruciferous veggies has the best protective effect per gram.
The study is published in BMC Gastroenterology.
