Cruciferous Vegetables

The more commonly known cruciferous vegetables include broccoli, cauliflower, and kale, but there are many others in this family, such as collard greens, watercress, bok choy, kohlrabi, rutabaga, turnips, arugula, radishes (including horseradish), wasabi, and all types of cabbage.

Cruciferous vegetables can potentially prevent DNA damage and metastatic cancer spread, activate defenses against pathogens and pollutants, help to prevent lymphoma, boost your liver detox enzymes, target breast cancer stem cells, and reduce the risk of prostate cancer progression. The component responsible for these benefits is thought to be sulforaphane, which is formed almost exclusively in cruciferous vegetables.

Beyond being a promising anticancer agent, sulforaphane may also help protect your brain and your eyesight, reduce nasal allergy inflammation, manage type 2 diabetes, and was recently found to successfully help treat autism. A placebo-controlled, double-blind, randomized trial of boys with autism found that about two to three cruciferous vegetable servings’ worth of sulforaphane a day improves social interaction, abnormal behavior, and verbal communication within a matter of weeks. The researchers, primarily from Harvard University and Johns Hopkins University, suggest that the effect might be due to sulforaphane’s role as a “detoxicant.”

For all these reasons, cruciferous vegetables get their own spot on my Daily Dozen, which recommends at least one serving of cruciferous vegetables and at least two additional servings of other vegetables a day, cruciferous or otherwise.

Indeed, if you were to add only one thing to your diet, consider cruciferous vegetables. Less than a single serving a day of broccoli, brussels sprouts, cabbage, cauliflower, or kale may cut the risk of cancer progression by more than half.
