Linked to lower cancer risk in some studies
Epidemiological studies have associated higher cruciferous vegetable intake with lower risk of certain cancers, including lung and colorectal. The National Cancer Institute notes the evidence is suggestive but not conclusive - worth knowing, not worth overstating.

Glucosinolates and sulforaphane
Crucifers contain sulfur-rich compounds called glucosinolates, which break down into biologically active products like sulforaphane - the subject of a large body of research on cellular defense mechanisms.
