Daily Dose of Cruciferous Veggies Linked to 20% Lower Colon Cancer Risk
A meta-analysis of 17 studies with 97,595 participants found that consuming 40–60 grams of cruciferous vegetables per day (about ½ cup broccoli or 2–3 cups raw kale) may cut colon cancer risk by ~20%, with the benefit plateauing around that amount. The protection is linked to glucosinolates that form anti-cancer isothiocyanates, which aid detoxification, reduce inflammation, and may slow cancer cell growth, while also boosting gut health through fiber and nutrients. Practical tips include adding broccoli in the air fryer, beef-and-broccoli stir-fries, roasted cauliflower with kale, or sneaking greens into smoothies or sauces; maintain variety (30+ plant types weekly) and stay on top of screenings, noting some people may experience gas when increasing cruciferous intake.
