Phytonutrients and Antioxidants
Cruciferous vegetables contain unique phytonutrients called glucosinolates. When broken down, these compounds form indoles and isothiocyanates, which have potential anti-cancer properties.
Sulforaphane, a powerful antioxidant, is formed from glucosinolates in cruciferous veggies. It may help reduce inflammation and oxidative stress in the body.
These vegetables are also rich in carotenoids, including beta-carotene, lutein, and zeaxanthin. These compounds support eye health and act as antioxidants.

Some people may experience gas when eating cruciferous veggies. Starting with small amounts and slowly increasing intake can help reduce this effect.
Cancer Prevention
Cruciferous vegetables contain compounds that may help prevent cancer. These compounds are called glucosinolates.
When the vegetables are chopped or chewed, glucosinolates break down into active compounds. These include indoles and isothiocyanates.
Studies show these compounds may:
- Stop cancer cells from growing
- Kill cancer cells
- Prevent tumors from forming new blood vessels
Research suggests eating cruciferous veggies may lower the risk of several types of cancer. These include lung, colorectal, breast, and prostate cancers.
